Failed Vulkan execution +does not retry neural inference on CPU. + +This recheck also carries the Vulkan queue/fence status through every public +GPU-only OCR stage (RGB front end, detector, DB postprocess, recognizer and +CTC). A device reset is therefore reported as `VK_ERROR_DEVICE_LOST`, not +mislabelled as an unsupported ONNX operator. The only retry allowed by the +GPU-only page batch scheduler is an N=1 Vulkan retry after a rejected N-batch; +it never invokes the CPU executor. On the local Radeon 780M / LLPC adapter, +production medium-detector `1x3x160x704` still fails closed with that result. +Changing command-segment size, forcing queue-idle, using a fresh command +buffer, using the isolated terminal-depthwise shader, or using its +generic/sliced variant did not make that shape stable. This is a driver +compatibility limit, not a CPU-fallback opportunity. + +### 2026-08-22 GPU-only deployment coverage + +`gpu_only` is a complete execution mode, not a request to accelerate only +selected layers: packed RGB upload/resize, detector, DB postprocess, +recognizer, CTC Top-1, and the real NCHW page/crop batch paths stay on one +Vulkan queue. Only final compact OCR records and UTF-8 construction reach +the host. A rejected N-batch is retried as strict Vulkan N=1; it is never +redirected to the CPU graph. + +The Vulkan loader is dynamically opened at runtime, so applications do not +link to Vulkan or ONNX Runtime. The build now embeds shaders with the +vendored Windows compiler when available, otherwise with a host +`glslangValidator`/`glslang`; the same executor is therefore buildable on +Windows x86/x64, Linux x86/x64, and Linux ARM/AArch64 when Vulkan headers and +a shader compiler are supplied. If the loader, compute queue, shader build, +or a required graph node is unavailable, constructor/runtime validation fails +closed rather than selecting CPU inference. + +After this portability change, the local Radeon 780M validation was rerun +with the rebuilt `build-gpu-only-ep` binaries: + +| Check | Result | +| --- | --- | +| tiny GPU-only OCR, `en` + `mixed` + low contrast, 2 repeats | passed; 8 records; max confidence delta `2.50e-5` | +| small GPU-only OCR, `en` + `mixed` | passed; 5 records; max confidence delta `1.0e-6` | +| tiny two-page GPU batch, `en` x2, 1 warm-up + 5 runs | serial `93.109 ms`, batch `84.491 ms`, `1.102x`; text/geometry equivalent | +| tiny GPU memory ladder, 16px through 1920px pages then back to small | all requests completed; post-large small/en/mixed returned to the warmed `596,709,376 B` private-byte baseline | + +The last memory sweep later rose by at most `9,392,128 B` after a noisy page +and finished `7,172,096 B` above that process allocator baseline.

Small-model memory +through the same small-to-large ladder returned to its warmed baseline after +the final screenshot (`1,020,276,736 B` private bytes); a low-contrast request +briefly added `14,577,664 B` in the process allocator and the final screenshot +was below baseline. `ui_dense_1920x1080` is deliberately excluded from the +qualified OCR corpus: it currently has one CPU/GPU decoded-result mismatch. +That failure is retained as a regression target rather than being masked by a +fallback or presented as a pass. + +The rebuilt `build-gpu-only-ep` binaries passed the currently qualified +coverage. The graph timing measurements below use two warmed runs on the same +machine and include the current host/device graph boundary: + +| Check | Result | +| --- | --- | +| tiny detector graph, `1x3x160x704` | passed; max error `5.63276e-7`; CPU/GPU `10.590 / 45.256 ms` | +| small detector graph, `1x3x160x704` | passed; max error `3.05939e-7`; CPU/GPU `18.676 / 66.362 ms` | +| medium detector graph, `1x3x160x640` | passed; max error `7.56991e-8`; CPU/GPU `80.312 / 272.255 ms` | +| GPU-only OCR tiny, `en` + `mixed` | passed; 5 records; max confidence delta `2.9e-6` | +| GPU-only OCR small, `en` | passed; 2 records; max confidence delta `8e-7` | +| true two-page GPU batch, tiny `en` x2 | serial-equivalent; `93.177 -> 90.993 ms` (`1.024x`) | +| true two-page GPU batch, small `en` x2 | serial-equivalent; `239.759 -> 231.595 ms` (`1.035x`) | + +The medium detector memory ladder +`64x128 -> 96x256 -> 128x512 -> 160x640 -> 64x128` also passed. At every +phase the live allocation returned to the `61,946,548`-byte immutable +constants baseline; reusable capacity reached `201,457,664` bytes and is +intentionally retained for later requests. These results validate qualified +GPU-only execution and recovery behavior, but do not claim that this UMA GPU +is faster than the AVX-512 CPU or an ORT GPU provider. + +The public GPU-only memory ladder also covered, in increasing source-size +order, `tiny_16x16`, `en`, `mixed`, `noisy_lowcontrast`, `wide_strip_3000x80`, +`tall_strip_80x3000`, `screenshot_1920x1080`, and `ui_dense_1920x1080`. +After the final large image, processing the next small image retained no extra +private bytes above the warmed large-page baseline. A later noisy page can +make the process allocator grow by about 12 MB for compact host result/control +storage; that allocation stayed bounded through the remaining large pages. +GPU replay command buffers and their pinned slots are now discarded whenever +the model uses the bounded detector/recognizer hand-off policy, so old replay +shapes cannot accumulate as device allocations. + +### 2026-08-22 hybrid Vulkan admission correction + +Hybrid terminal CTC GEMM now follows the documented policy exactly: for the +same model shape, CPU worker budget, Vulkan adapter, and Vulkan runtime +generation, it is admitted when a complete upload/compute/download boundary +is **no slower than CPU**. The older `GPU <= CPU / 2` rule could reject an +equal-speed GPU path merely because multiple recognizer crops might execute +concurrently on CPU. Queue serialization is instead controlled at the OCR +scheduler boundary. The admission cache is now also tagged with the Vulkan +runtime generation, so a device-loss rebuild always re-measures rather than +reusing an answer from the old device. + +On this Radeon 780M host, tiny `en` CTC terminal shapes measured `1.361 /` +`0.718 ms` and `1.846 / 1.281 ms` for GPU/CPU, so they correctly remain CPU +on this adapter. This is expected: the implementation enables Vulkan only on +actual no-slower results, and does not manufacture a GPU claim from a slower +boundary. The hybrid batch regression (`tiny_16x16`, `en`, `mixed`, low +contrast; 2-page scheduling) remained text/geometry equivalent and measured +`67.358 -> 63.918 ms` (`1.054x`). + +### 2026-08-21 GPU-only requalification + +#### Latest local recheck + +The strict Vulkan build was rebuilt after removing an unproven automatic +generic-tail experiment. The standard terminal scalar depthwise selection is +restored for qualified shapes. The following tests were rerun on AMD Radeon +780M / LLPC; all use the pure C++ implementation without ONNX Runtime: + +| Check | Result | +| --- | --- | +| tiny detector graph, `1x3x160x704` | passed, max error `5.63276e-7` | +| medium detector graph, `1x3x160x640` | passed, max error `7.56991e-8` | +| medium detector graph, `1x3x160x768` | passed, max error `3.25672e-8` | +| medium recognizer graph, `1x3x48x320` | passed, max error `2.66433e-5` | +| GPU-only OCR tiny, `en` + `mixed` | passed; 5 records; max confidence delta `2.9e-6` | +| GPU-only OCR small, `en` | passed; 2 records; max confidence delta `8e-7` | +| tiny graph memory ladder, `64x128 -> 96x256 -> 128x512 -> 160x704 -> 64x128` | passed; live device bytes always returned to `1,713,924` B | + +The production medium detector at `1x3x160x704` still returns +`VK_ERROR_DEVICE_LOST` on this driver after the terminal `896x5x22` depthwise +stage. With the normal 20-node segmentation the failure is observed on the +segment ending at that stage; a diagnostic command-stream grouping can submit +that tail and subsequently fails in the FPN head. This identifies a +Radeon 780M/LLPC Vulkan command-stream stability issue rather than a usable +CPU fallback point. It remains deliberately fail-closed: no CPU neural or +postprocess substitute is used. This blocks a claim of complete all-model +GPU-only qualification on the local adapter. + +The end-to-end GPU path was rebuilt from the conservative source and retested +on Radeon 780M/LLPC. A GPU crop may use a dynamic width; it is no longer +rounded to 64 columns, because padded input columns produce extra valid +CNN/CTC time rows and can alter a short crop's text or confidence. + +| GPU-only OCR pair | Corpus | Result | +| --- | --- | --- | +| tiny | `tiny_16x16`, `en`, `noisy_lowcontrast`, `wide_strip_3000x80` | 7 results; exact text/geometry; max confidence error `2.50e-5` | +| tiny replay | `en` repeated 5 times on one live OCR instance | 10 results; exact text/geometry; max confidence error `4e-7` | +| small | `en`, `noisy_lowcontrast` | 5 results; exact text/geometry; max confidence error `1.3e-6` | + +The strict graph sweep (three runs except medium detector, two) also passed: +tiny detector `9.367 / 28.870 ms` CPU/Vulkan, tiny recognizer `5.224 / 23.189 +ms`, small detector `17.976 / 48.075 ms`, small recognizer `13.320 / 62.323 +ms`, medium recognizer `30.569 / 123.212 ms`, and the qualified medium +detector shape `1x3x128x704` `78.976 / 234.478 ms`. These are full graph +latencies on this UMA GPU, not an assertion that it beats the AVX-512 CPU. +Maximum graph-output errors were `5.63e-7`, `2.18e-5`, `3.06e-7`, `3.78e-4`, +`2.66e-5`, and `6.71e-9` respectively. + +GPU arena recovery was also rerun after the correction. In every small-to- +large-to-small phase, dynamic `activation_bytes=0` after completion: + +| Graph ladder | Immutable live baseline | Final reusable capacity | +| --- | ---: | ---: | +| tiny detector through `1x3x160x704` | 1,713,924 B | 47,513,600 B | +| small detector through `1x3x160x704` | 9,813,844 B | 75,235,328 B | +| medium recognizer through `2x3x48x320` | 76,456,140 B | 174,850,048 B | + +### 2026-08-21 verification update + +The strict GPU graph replay policy was corrected for public host-input +`Run()` calls. Replay remains enabled for device-input and in-graph RGB +execution, while host-input calls now release their dynamic activation slots +when the submission completes. This is an arena-lifetime change only: every +neural operator remains a Vulkan dispatch and an unsupported or failed device +operation still fails closed. + +The reproducible tiny-detector ladder +`1x3x64x128 -> 1x3x96x256 -> 1x3x128x512 -> 1x3x160x704 -> 1x3x64x128` +now passes `ppocr_gpu_graph_mem_soak`. Its immutable live baseline is +**1,713,924 bytes**; after every sample, including the largest one, live +bytes return exactly to that baseline. Reusable arena capacity grows to +**47,513,600 bytes** at the largest input and intentionally stays available +for the final small input, so capacity is not misreported as a live-memory +leak. + +The same live-memory invariant also passed for the qualified medium-detector +ladder ending at `1x3x160x640`: its **61,946,548-byte** immutable baseline +was recovered after each sample, with a stable **216,072,192-byte** reusable +high-water capacity. + +The medium detector was rechecked at the production `1x3x160x704` input. +On this Radeon 780M/LLPC driver it still fails closed with +`VK_ERROR_DEVICE_LOST` in the terminal `896x5x22` depthwise dispatch. The +dedicated scalar shader is now selected automatically for that exact Vulkan +operator (use `PPOCR_GPU_TAIL_GENERIC=1` only for diagnostics); it also fails +closed on this production shape, as did device-local and host-cached arena +variants. The nearby qualified `1x3x160x640` and `1x3x160x768` shapes pass +CPU/Vulkan output comparison, which further confirms this is a driver/shape +interaction rather than a CPU fallback. + +Hybrid RGB front ends are now admission-driven by default: detector RGB+stem +and recognizer RGB+Conv.0 run only after their complete upload/dispatch/ +readback boundary is both numerically validated and no slower than the native +SIMD path. `PPOCR_DISABLE_VULKAN_RGB_STEM` and +`PPOCR_DISABLE_VULKAN_REC_RGB_CONV` disable those probes for diagnostics; no +enable-only switch is required. + +The default strict-graph command segment is now **20 nodes** (override with +`PPOCR_GPU_ONLY_SEGMENT_NODES`). A fresh three-run Vulkan sweep selected that +setting for the Radeon 780M: detector graph means were tiny `30.201 ms`, +small `46.590 ms`, and qualified medium `239.388 ms`; recognizer means at +`1x3x48x320` were tiny `23.169 ms`, small `60.031 ms`, and medium +`123.182 ms`. CPU/Vulkan maximum output errors remained respectively +`5.63e-7`, `3.06e-7`, `6.71e-9`, `2.18e-5`, `3.78e-4`, and `2.66e-5`. +This is a segment-lifetime optimization, not an assertion that the local UMA +GPU is faster than the AVX-512 CPU. + +Memory recovery was also exercised across detector resolution and recognizer +width/batch diversity. Small detector `64x128 -> 96x256 -> 128x512 -> +160x704 -> 64x128` always returned to its **9,813,844-byte** constants +baseline. The medium recognizer ladder `1x3x48x64 -> 1x3x48x160 -> +1x3x48x320 -> 2x3x48x320 -> 1x3x48x64` always returned to its +**76,456,140-byte** constants baseline. Capacity is intentionally retained +as reusable GPU storage; no dynamic activation remains live after a sample. + +The CPU batch executor now supports real same-shape detector NCHW batches +through both fused `MaxPool -> Concat -> Conv` and `Concat -> Conv` nodes. +Those nodes now advance each source by its own NCHW channel-plane stride, so +unequal concat branches cannot cross-contaminate pages. The varied-size +four-image detector-batch regression passes for tiny/small/medium: decoded +text and geometry are exact, while FP32 confidence is checked against its +documented bounded tolerance. `rec_batch_size` now defaults to `1` because +this PP-OCRv6 transformer export can change CTC results for N>1 recognition +crops; deployments may still opt in and qualify it independently. GPU-only +retains its separate device-resident crop batching path. + +The full small-to-large-to-small memory ladder (19 images, including +`5120x2880`, `7680x4320`, wide and tall aspect ratios) also passed for every +CPU model. Per-resolution private-byte and working-set evidence is retained +in `build-gpu-only-final/memory_ladder_{tiny,small,medium}_cpu_20260821.json`. +In each run both counters fell below the post-8K high-water during the +recovery tail; final-small private memory was within **-0.05% / +0.33% / ++1.06%** of the warmed tiny/small/medium baselines respectively. + +The current five-image CPU comparison is recorded in +`build-gpu-only-final/cpu_diverse_benchmark_20260821.json`. On this local +AVX-512 host (16 threads, two warmups, eight runs per case), native C++ beat +the installed ONNX Runtime 1.28.0 CPU provider on every case: + +| PP-OCRv6 model | weighted latency improvement | weakest case | +| --- | ---: | ---: | +| tiny | 73.54% | 63.33% | +| small | 46.16% | 36.22% | +| medium | 9.22% | 1.45% | + +This is a local CPU-only result. The installed ORT package lists +`AzureExecutionProvider` and `CPUExecutionProvider`; its observed variance, +especially on small inputs, means these figures are not a portable GPU or +architecture-wide claim. + +## CPU acceleration and architecture support + +The inference path remains dependency-free and portable across x86/x64 and +ARM/AArch64. Hot contiguous elementwise paths (Add/Sub/Mul/Div, ReLU, +HardSwish, and affine scale/shift), +pointwise `1x1` convolutions, ordinary/depthwise `3x3`/`5x5` convolutions, +spatial mean reduction, fused BatchNorm+GELU, and attention `MatMul` use +fused vector kernels: + +- x86/x64: AVX-512F/FMA when supported by the running CPU and OS; otherwise + AVX2/FMA; otherwise scalar code. Advanced ISA code is compiled into separate + translation units and selected only after runtime CPUID/OS-state checks. +- ARM/AArch64: NEON when the compiler/target exposes it, with a scalar + fallback otherwise. +- Larger GEMMs are divided over CPU cores; small GEMMs stay single-threaded to + avoid thread-launch overhead. Direct convolutions use a persistent worker set + (rather than creating threads per operator), defaulting to at most 16 workers; + `PPOCR_BENCH_THREADS` is an explicit override for deployment tuning and A/B + tests. +- PPOCR_DISABLE_AVX512=1 is an optional per-process A/B switch for x86 + deployments. It keeps all runtime safety checks and selects AVX2/FMA when a + particular AVX-512 CPU or workload performs better at its non-AVX-512 clock. +- `ppocr_kernel_smoke` verifies paired/odd GEMM rows, scalar/vector column + tails, optional bias, and a recognizer-sized projection. Run it normally and + with `PPOCR_DISABLE_AVX512=1` to cover the dynamic AVX-512 and AVX2 paths. +- PPOCR_DISABLE_AVX512_POINTWISE8=1 is a narrower A/B switch for the AVX-512 + eight-output `1x1` register tile. It retains AVX-512 and its four-output + pointwise kernel, so deployments can isolate this tile's cache/register + trade-off without changing the baseline ISA. A current three-model A/B + confirmed that this decision is shape-sensitive: do not globally force the + wider tile merely because AVX-512 is available. +- PPOCR_ENABLE_AVX512_POINTWISE_RELU8=1 opt-in enables the analogous + eight-output `1x1 Conv+ReLU` tile for deployment-local testing. The stable + four-output fused-ReLU path remains the default because the wider tile's + end-to-end result is workload/cache sensitive. +- Large stride-one `3x3` feature maps can likewise use an AVX-512 eight-output + channel tile. It shares each input vector across eight output reductions; + the dispatcher restricts it to maps of at least 16,384 pixels and falls back + to the four-output tile for smaller layers, odd channel tails, AVX2, NEON, + and scalar targets. `PPOCR_DISABLE_AVX512_CONV3X3_TILE8=1` keeps the + four-output AVX-512 path for deployment A/B. The low-level regression now + checks both an eight-channel tile and a nine-channel ReLU tail, which also + caught and fixed the prior un-clamped SIMD tail-channel bug. +- AVX-512 also has a dedicated unit-stride `2x2 SAME_UPPER` convolution path + for the detector reconstruction stem. Its large valid interior uses four + explicit FMA loads per input channel; only the final row/column runs the + ONNX zero-padding boundary formula. It is dynamically selected only on a + supported AVX-512 CPU, preserves the AVX2/scalar fallback, and can be A/B + disabled with `PPOCR_DISABLE_AVX512_CONV2X2_SAME=1`. +- Equal-shape residual `1x1 Conv -> Add` pairs are fused at graph load and, + on a runtime-eligible AVX-512, AVX2, or NEON CPU, keep the convolution + accumulators live until the final residual add/store. This removes the + intermediate Conv activation read/write. The executor validates the + residual's runtime NCHW shape before selecting that kernel; scalar, + broadcast, and unexpected-shape cases retain the existing exact + Conv-then-Add path. +- Post-folding `Conv -> Sigmoid` and `Conv -> HardSigmoid` gate pairs are + also fused. Their convolution result is activated in place, removing the + generic unary output allocation; HardSigmoid uses one exact SIMD pass for + `clamp(alpha*x+beta, 0, 1)` on AVX-512, AVX2, and NEON. +- Direct `Conv -> Add([1,C,1,1])` channel biases are folded into immutable + convolution biases at graph load. If the Add is followed by ReLU, the three + operations become one fused Conv+ReLU node. This covers the recognizer stem + and avoids a full NCHW broadcast traversal and activation allocation. +- Recognition `Conv -> Sigmoid -> Mul` Swish gates are recognized after + Conv+BatchNorm folding. The fused node writes `x * sigmoid(x)` directly into + the Conv destination, eliminating the two branch activation tensors while + retaining the exact FP32 operation order. The standalone BatchNorm variant + follows the same rule when a model cannot fold the affine layer. +- `PPOCR_APPROX_GELU=1` is an opt-in PP-OCRv6 deployment mode for eligible + model-aware fused BatchNorm+GELU planes. Its AVX-512/AVX2 dispatch is based + on per-plane shape rather than total batch size, so batching cannot change a + page's GELU implementation; generic GELU retains exact ONNX Erf semantics. + +Model constants are no longer copied for every `Run()` invocation: they stay +in the immutable model store and execution allocates only inputs and temporary +tensors. This substantially lowers peak transient memory usage for the +detector/recognizer. + +Example cross builds (use the appropriate compiler/toolchain installed by your +environment): + +```powershell +# Native ARM64 build (Visual Studio developer prompt) +cmake -S . -B build-arm64 -A ARM64 +cmake --build build-arm64 --config Release + +# Cross build using an ARM64 CMake toolchain file +cmake -S . -B build-aarch64 -DCMAKE_TOOLCHAIN_FILE=toolchains/aarch64.cmake +cmake --build build-aarch64 --parallel +``` + +The generic executor is not compiled for a host-specific ISA, avoiding +accidental illegal instructions on older x86 CPUs and on ARM targets. The +AVX-512 path remains the default on a supported CPU, while the switch is kept +for deployment-specific validation. + +## ONNX Runtime comparison benchmark + +The repository contains a repeatable CPU-only benchmark. It compares the +complete detector + recognition pipeline on the same PPM image, uses ONNX +Runtime's `CPUExecutionProvider`, warms up both engines, and reports mean, +median, p95, load latency and throughput. + +```powershell +cmake -S . -B build -G "MinGW Makefiles" +cmake --build build --parallel +powershell -ExecutionPolicy Bypass -File .\bench\compare.ps1 -Runs 20 -Warmup 3 +``` + +### 2026-08-14: wider correctness corpus and normalization A/B + +The regression runner now accepts a UTF-8-BOM JSON case manifest as well as +plain UTF-8. This makes a small PowerShell-authored subset reproducible rather +than failing before inference. The current native validation covered all three +models against ONNX Runtime text output on English, Chinese, and `3000x80` +wide text (`3/3` cases each): +`build/accuracy_default_preprocess_ab_{tiny,small,medium}_20260814.json`. + +Stress coverage also includes dense UI, tall text, and a `2560x1440` +screenshot. Tiny completed all 11 built-in cases; focused high-cost samples +completed for small (`3/3`) and medium (`2/2`), including 38 medium screenshot +regions. Reports are under `build/stress_*_current_20260814.json`. + +Preprocessing retains its exact fused bilinear + normalization path. A compact +256-entry uint8 normalization lookup implementation was evaluated, but it +regressed medium on this AVX-512 host due to indexed-load/cache pressure. It +therefore remains an opt-in A/B switch (`PPOCR_ENABLE_PREPROCESS_NORMALIZE_LUT=1`) +rather than changing the production default. The paired result is recorded in +`build/bench_preprocess_lut_ab_current_20260814.json`; this keeps the default +chosen by measured end-to-end performance, not by a microbenchmark assumption. + +The runtime AVX-512 dispatch remains dynamic: its current 15-run English A/B +against the AVX2 fallback measured **29.520 vs 34.133 ms** (tiny), **56.578 vs +80.106 ms** (small), and **212.366 vs 323.044 ms** (medium). See +`build/bench_avx512_dynamic_current_20260814.json`. Vulkan smoke continues to +pass on AMD Radeon 780M and admits the channel-affine+Swish and depthwise+Swish +GPU segments only when their complete transfer/dispatch/readback timing is no +slower than CPU. GPU-only correctly refuses construction until the complete +PP-OCRv6 device graph exists; it never silently runs CPU work. + +`compare.ps1` now treats the requested performance target as a gate. Its +`-MinImprovementPercent` parameter defaults to `30`, and it returns a non-zero +exit code when end-to-end native latency is not at least that much lower than +the paired ONNX Runtime CPU measurement. Set it explicitly when a deployment +uses a different threshold. + +`bench/ort_bench.py` requires `onnxruntime`, `numpy`, and Pillow in the Python +environment chosen by `bench/compare.ps1`. `ppocr_bench` keeps the native OCR +instance alive during all warmup/measurement iterations, so model parsing and +weight loading are excluded from steady-state latency just as they are in the +ONNX Runtime side. + +### Latest measured result + +The latest comparison is two consecutive `bench/compare.ps1` runs (tiny +det+rec, `build/regression_ppm/en.ppm`, `PPOCR_BACKEND=cpu`, 16 threads, 3 +warmup / 20 measured, `PPOCR_APPROX_GELU` unset) captured on 2026-08-20 after +fusing the inverted-residual `1x1 expand → exact GELU → 1x1 project → residual +Add` into one spatial-tiled AVX-512 kernel (10 detector + 7 recognizer sites), +plus the prior AVX-512 stem/FPN/GEMM path. Model loading is excluded from +steady-state time. Figures are copied from those two JSON blobs; they are not +averaged into a third number. + +| Run | Engine | Mean latency | Throughput | C++ / ORT | Latency improvement | +|---|---|---:|---:|---:|---:| +| 1 | Pure C++ PP-OCRv6 | 20.972 ms | 47.682 FPS | 0.208x | 79.16% | +| 1 | ONNX Runtime 1.28 CPUExecutionProvider | 100.631 ms | 9.937 FPS | | | +| 2 | Pure C++ PP-OCRv6 | 20.973 ms | 47.681 FPS | 0.209x | 79.15% | +| 2 | ONNX Runtime 1.28 CPUExecutionProvider | 100.588 ms | 9.942 FPS | | | + +Both runs used `faster_engine = ppocr_cpp`. Native median/p95 were +20.884/23.443 ms and 20.376/23.720 ms. Relative to this change's pre-change +native ceiling of 30.280 ms, the pair is 30.7% / 30.7% lower latency +(each mean ≤ 21.196 ms). This is a host-specific result, not a portable +performance guarantee; rerun on the deployment CPU before capacity planning. + +The previous pair after AVX-512 stride-2 tiles / fused MaxPool+Concat / FPN +Concat+Conv was 24.721 / 24.887 ms native vs 125.828 / 102.010 ms ONNX Runtime +(80.35% / 75.60%). The AVX2 exact-Erf GELU pair was 26.397 / 26.357 ms vs +99.273 / 111.544 ms (73.41% / 76.37%). The longer 60-run snapshot (2026-08-11, +8 warmup) on `build/en.ppm` was 33.074 ms native vs 138.359 ms ONNX Runtime. +Keep those as historical context only; the table above is the current +`compare.ps1` pair. + +Reproduce the benchmark with: + +```powershell +powershell -NoProfile -ExecutionPolicy Bypass -File .\bench\compare.ps1 ` + -Runs 20 -Warmup 3 -Threads 16 -Backend cpu ` + -NativeExe .\build-gpu-only-final\ppocr_bench.exe +``` + +`bench/compare.ps1` drives the tiny pair. For small/medium, invoke +`build/ppocr_bench.exe` and `bench/ort_bench.py` directly with their matching +models and dictionary, as shown by the commands below. + +### Current three-model CPU comparison + +After the ARM/NEON GEMM bias-broadcast correction, the current x86 AVX-512 +build was rerun on `build/en.ppm` with `PPOCR_BENCH_THREADS=16`, three warmups, +and ten timed runs per engine. The native and ONNX Runtime runs use the same +detector/recognizer pair, complete OCR pipeline, image, thread budget, and +warmup/run counts. This is a fresh shared-host snapshot rather than a portable +guarantee, but it confirms that all three supported PP-OCRv6 sizes remain well +ahead of ONNX Runtime CPUExecutionProvider: + +| Model | Pure C++ mean | ORT mean | C++ / ORT | C++ latency reduction | +|---|---:|---:|---:|---:| +| tiny | 29.757 ms | 142.158 ms | 0.209x | 79.1% | +| small | 63.395 ms | 198.205 ms | 0.320x | 68.0% | +| medium | 191.198 ms | 374.134 ms | 0.511x | 48.9% | + +The corresponding native throughput was 33.606, 15.774, and 5.230 FPS, +compared with ORT's 7.034, 5.045, and 2.673 FPS. Re-run the paired commands on +the deployment hardware before using these values for capacity planning. +The scalar/NEON GEMM fallback was also corrected to broadcast the bias by +output column (the same semantics as AVX-512/AVX2), rather than incorrectly +using one bias value for a whole output row. This is a correctness fix for +ARM targets and does not change the dynamically dispatched x86 measurements. + +### 2026-08-13: refreshed long three-model CPU/ORT comparison + +After the AVX-512 stride-one `3x3` eight-output tile was revalidated as the +default on all three model sizes, the complete `en.ppm` OCR pipeline was +rerun with 16 native/ORT CPU workers, five warmups, and 40 timed iterations +per engine. This is the longer same-host measurement; it includes detector, +crop construction, recognizer, and decoding, but excludes model loading from +steady-state latency. ORT used CPUExecutionProvider only. + +| Model | Pure C++ mean | ORT mean | C++ / ORT | C++ latency reduction | +|---|---:|---:|---:|---:| +| tiny | 32.244 ms | 119.475 ms | 0.270x | 73.0% | +| small | 67.857 ms | 151.359 ms | 0.448x | 55.2% | +| medium | 220.768 ms | 365.267 ms | 0.604x | 39.6% | + +All three exceed the repository's 30% paired CPU performance gate on this +host. The benchmark samples remain machine-specific and ORT has wider timing +variation on this shared Windows host; full raw measurements are retained in +`build/compare_three_models_tile8_long_20260813.json`, so this table is not a +cross-platform guarantee. + +### 2026-08-11: refreshed three-model exact CPU comparison + +A fresh paired short run on `regression_ppm/en.ppm` used the same complete +OCR pipeline, matching 16-thread budgets, three warm-ups, and ten timed runs. +AVX-512 was dynamically selected on this x86 host; no approximation mode was +enabled. The native and ORT measurements were executed separately on a shared +Windows machine, so these are reproducible evidence for this host閳ユ攺ot a +portable capacity promise. + +| Model | Pure C++ mean | ORT mean | C++ / ORT | C++ latency reduction | +|---|---:|---:|---:|---:| +| tiny | 31.251 ms | 129.990 ms | 0.240x | 76.0% | +| small | 70.912 ms | 201.911 ms | 0.351x | 64.9% | +| medium | 199.734 ms | 409.505 ms | 0.488x | 51.2% | + +This refresh keeps all three PP-OCRv6 sizes above the requested 30% native +CPU latency advantage on the same exact input. It follows the recognizer +executor lifetime fix that now executes `FusedBatchNormSwishAdd` in the +terminal-CTC path as well as the ordinary graph executor. The path reuses the +dying BatchNorm activation for affine + exact Swish + shortcut Add, reducing +the live feature-map frontier for small/medium crop batches. A profile confirms +the node as `ctc:FusedBatchNormSwishAdd:BatchNormalization.2_swish_add`. + +The batch/memory follow-up used six varied PP-OCRv6 tiny inputs閳ユ攩rom `16x16` +through a `3000x80` strip閳ユ敋ith English, Chinese, and mixed content. Serial and +`RecognizeBatch()` outputs were identical (10 total results); bounded two-page +scheduling measured **134.218 ms serial / 86.501 ms batch (1.552x)**. A +medium-model memory cycle spanning `16x16`, mixed text, and a dense +`1920x1080` page used 369,672,192 private bytes after warm-up and finished at ++3,145,728 bytes. This is a Windows allocator high-water observation, not a +leak assertion; it bounds the varied-shape batch check to a small transient +increase rather than retaining every crop workspace. + +## Vulkan backend status + +The public API now exposes `ppocr::Backend::{cpu_only,gpu_only,hybrid}` and +`QueryBackendInfo()`. Runtime Vulkan probing is compiled from vendored Khronos +headers and dynamically loads `vulkan-1.dll`, so the binary does not require a +Vulkan SDK installation on its deployment machine. A generated SPIR-V compute +shader and smoke executable validate FP32 Add/Sub/Mul/Div building blocks over +scalar, non-workgroup-aligned, and recognizer-scale tensor sizes. +On this host, `ppocr_demo --backend-info` and `ppocr_vulkan_smoke` report the +AMD Radeon 780M compute queue and pass those correctness checks. + +`gpu_only` deliberately fails if a complete PP-OCRv6 GPU graph is not +available; it never silently falls back to CPU. `hybrid` now connects verified +equal-shape in-place Add/Sub/Mul/Div executor nodes and eligible `1x1` Conv +nodes to Vulkan. For NCHW recognition tensors it maps N to the shader's Y +dimension, so a same-width crop batch uses one submission instead of one +submission per crop. A cached +per-shape/per-operation admission benchmark validates results and includes +host/device transfer, dispatch, and readback before it may select GPU; all +other operators remain on the portable CPU path. The Vulkan loader, instance, +device, queue, pipeline, descriptor set, command buffer, and grow-only +host-visible buffers are persistent, avoiding a per-dispatch Vulkan rebuild. + +### 2026-08-12: depthwise GPU activation fusion + +The batched Vulkan depthwise primitive now fuses its directly following +`ReLU` or exact `Swish` into the convolution writeback. This covers the +common PP-OCRv6 MobileNet depthwise-gate shape without creating a CPU-side +activation pass or an intermediate host tensor. The runtime still performs +shape-specific full-boundary admission (H2D, dispatch, fence, D2H, and CPU +SIMD comparison), and the new Vulkan smoke case validates batched odd-size +depthwise+Swish values against the scalar reference. It is therefore a +batch-capable hybrid building block, not a claim that the still-partial GPU +graph is universally faster; `gpu_only` remains unavailable. + +On the local Radeon 780M, the `N=4,C=32,H=31,W=29,3x3` admission sample was +**0.36344 ms GPU vs 0.62156 ms CPU**, so hybrid selected the fused GPU path. +The unfused depthwise sample in the same run was **0.33214 ms GPU vs 0.34084 +ms CPU**. These figures include all transfers and synchronization and are +recorded as a per-segment comparison, not an end-to-end OCR claim. + +The same depthwise kernel now also has a fused exact HardSwish variant for +PP-OCRv6 MobileNet blocks. Its smoke admission sample measured **0.32760 ms +GPU vs 0.32076 ms CPU**, so hybrid correctly retained CPU for that shape; +the decision is dynamic rather than a blanket GPU preference. + +### 2026-08-12: five-size batch and memory recheck + +After the depthwise fusion work, CPU and hybrid `RecognizeBatch()` were +rechecked against serial execution on five deliberately different inputs: +`16x16`, English text, low-contrast text, a `3000x80` ultra-wide strip, and +CJK. All three official model sizes preserved exactly the same nested OCR +results. With one page worker, `det_batch_size=4`, and `rec_batch_size=4`, the +CPU measured serial/batch pairs were tiny **204.163/190.580 ms (1.071x)**, +small **392.496/375.710 ms (1.045x)**, and medium +**1260.420/1304.108 ms (0.967x)**. This mixed-shape result confirms that +batching is bounded-capacity scheduling rather than an unconditional latency +promise. The corresponding hybrid run was also result-identical (tiny +**204.311/210.308 ms**, small **436.332/411.353 ms**, medium +**1420.791/1461.834 ms**). + +For compatible same-shape work, eight `en.ppm` pages with `det_batch_size=8` +and `rec_batch_size=8` measured **1.485x** CPU page-batch throughput for tiny +and **1.201x** for small. Medium did not benefit in that shared-host sample +(**0.911x**), and is therefore left with the conservative defaults rather +than promoting a batch size that regresses it. A two-cycle five-size tiny +memory soak started from **137,195,520 bytes** after warm-up and ended at +**+32,768** then **-151,552 bytes**, showing no retained per-shape activation +frontier. + +Decoded-text comparison against ONNX Runtime was also rerun after these +changes for tiny, small, and medium on four diverse dimensions (`16x16`, +English, low-contrast, and `3000x80`): all **12/12** cases passed. + +### 2026-08-12: GPU-aware batch regression refresh + +The GPU and batch paths were rerun after the latest Vulkan/CPU optimization +pass. The public `RecognizeBatch()` API uses an exact-shape `[N,3,H,W]` +detector batch and same-width `[N,3,48,W]` recognizer crop batch; it never +rescales or pads unrelated page sizes merely to enlarge `N`. `det_batch_size`, +`rec_batch_size`, `rec_batch_width_bucket`, and `image_batch_parallelism` +remain the bounded controls, with `ppocr_batch_smoke` checking every batched +result against serial OCR before timing it. + +On the local AVX-512 / Radeon 780M host, eight identical `en.ppm` tiny-model +pages (`det_batch_size=8`, `rec_batch_size=8`, one page worker) returned the +same 16 decoded results as serial execution. The measured CPU serial/batch +pair was **329.520 / 201.876 ms (1.632x)**; hybrid was **382.402 / 237.445 ms +(1.610x)**. A five-size small-model check (`16x16`, English, low contrast, +`3000x80`, CJK; batch sizes 4) likewise preserved all 9 results: CPU +**520.065 / 512.529 ms (1.015x)** and hybrid **438.718 / 427.016 ms +(1.027x)**. The mixed-size figures are intentionally not presented as a +universal throughput guarantee. + +The refreshed Radeon Vulkan primitive suite passed numerical validation for +every existing batch primitive. Its strict full-boundary probes again admitted +the heavier fused work where it won (affine+Swish **0.16926 ms GPU vs 0.31296 +ms CPU**; depthwise+Swish **0.36218 vs 0.66808 ms**; depthwise+HardSwish +**0.36482 vs 0.37636 ms**) and retained CPU for transfer-bound `1x1` Conv, +ordinary/transpose Conv, resize+add, and GEMM. This is intentional dynamic +selection: `gpu_only` remains explicitly unavailable until the complete +detector, recognizer, transformer, and CTC graph are device-resident. + +### 2026-08-12: three-model CPU/GPU batch baseline refresh + +The current pure-C++ build was rebuilt and rechecked on the complete +tiny/small/medium model set. The SIMD kernel suite passed under normal +AVX-512 dispatch and again with `PPOCR_DISABLE_AVX512=1`, exercising the AVX2 +fallback. The Vulkan smoke suite passed on the Radeon 780M, including batched +binary/broadcast/affine/pointwise/depthwise/ordinary-convolution/transpose/ +resize-add/GEMM primitives. In that run the full-boundary admission policy +selected Vulkan for depthwise (**0.35698 vs 0.36624 ms**), depthwise+Swish +(**0.35930 vs 0.59468 ms**), depthwise+HardSwish (**0.34864 vs 0.41902 ms**), +and affine+Swish (**0.17778 vs 0.34676 ms**); all transfer-bound primitives +stayed on CPU. The decision is shape-local and dynamic, so it lowers CPU work +without forcing a slower device boundary. + +Decoded-text parity against ONNX Runtime passed **4/4** diverse inputs for +each model (tiny, small, medium): `16x16`, English, low contrast, and an +ultra-wide `3000x80` strip. A five-size serial-versus-batch gate for medium +also preserved all 9 results in CPU and hybrid modes. Its measured CPU pair +was **1257.378 / 1292.344 ms** and hybrid was **1266.158 / 1279.121 ms**; +this heterogeneous batch did not improve latency, so it is recorded as a +correctness/capacity check rather than a throughput claim. + +For an `en.ppm` single-page steady-state snapshot (two warmups, five runs, +16 kernel workers), current CPU means were tiny **38.755 ms**, small +**73.192 ms**, and medium **208.209 ms**. Hybrid means were **34.575 ms**, +**75.141 ms**, and **238.014 ms** respectively. The short shared-host sample +therefore supports hybrid for tiny when the admitted GPU segments help, while +CPU remains the sensible choice for small/medium on this UMA device. These +numbers are host-specific and do not change the explicit `gpu_only` contract. + +### 2026-08-12: hybrid admission re-audit + +The next GPU-admission pass measured the current single-primitive boundaries +again instead of lowering thresholds blindly. On this Radeon 780M, batched +depthwise+Swish remained a useful GPU segment (**0.32756 ms GPU vs 0.57274 ms +CPU**), and the depthwise+HardSwish sample also crossed the no-slower rule +(**0.32540 vs 0.36794 ms**). Pointwise Conv, ordinary Conv, transpose Conv, +resize/add, and GEMM samples remained transfer/synchronization-bound, so they +continue on CPU. This preserves the hybrid contract: GPU is selected whenever +the complete measured boundary is equal or faster, not merely because a +shader exists. + +The current source also retains conservative size guards before invoking an +admission microbenchmark. A short experiment removing them caused extra +small-shape probes and worse end-to-end tiny behavior on this UMA device, so +the guards were retained. Fresh post-audit checks passed kernel SIMD smoke, +the full Vulkan smoke suite, three-model four-size ONNX Runtime decoded-text +parity (**12/12**), five-size serial/batch output identity, and a medium +hybrid two-cycle memory soak. The latter began at **494,878,720 bytes** after +warm-up and ended **9,105,408** and **11,042,816 bytes below** baseline. + +### 2026-08-12: GPU batch revalidation + +GPU execution remains batch-aware: equal-width recognition crops are one NCHW +Vulkan dispatch (the shader maps crop `N` to its Y dimension), while the CPU +page scheduler bounds concurrent detector/recognizer workspaces. The pointwise +Conv shader stages compact immutable `[M,C]` weights in workgroup memory and +handles normal, ReLU, Swish, Sigmoid, and residual-Swish forms without an +intermediate activation. Hybrid admission still measures the entire H2D + +dispatch + D2H path for each shape and uses GPU only when the validated result +is no slower than the CPU SIMD counterpart. + +### 2026-08-12: exact-shape detector batching + +`RecognizeBatch()` now also coalesces pages whose normal PP-OCR detector +resize dimensions are exactly equal. This is a real `[N,3,H,W]` detector +batch: no document is padded, and each result is independently DB +postprocessed from its own probability-map slice. `Options::det_batch_size` +(default `4`) bounds the detector activation frontier; the smoke harness +accepts `PPOCR_DET_BATCH_SIZE` for A/B runs. CPU batch kernels therefore see +useful detector `N` work in addition to the existing same-width recognizer +crop batches. + +The current hybrid path deliberately keeps this new detector batching at +`N=1`. Its Vulkan coverage is still partial and synchronous, so applying an +unproven large detector GPU segment would be transfer/admission-bound rather +than an optimization. CPU-only detector batches are available now; hybrid +continues to batch recognizer crops and only admits validated no-slower GPU +segments. This preserves the explicit `gpu_only` contract: full GPU OCR is +not claimed until detector, recognizer, transformer, and CTC stay +device-resident. + +On this AVX-512 / Radeon 780M host, tiny PP-OCRv6 over eight identical +`en.ppm` pages (recognizer batch `8`, one worker) produced exactly the same +16 OCR results as serial inference. The steady-state smoke measurement was +**323.281 ms serial / 195.744 ms batch (1.652x)** with `PPOCR_DET_BATCH_SIZE=8`, +versus **330.019 / 247.684 ms (1.332x)** with detector batching forced to one. +The hybrid check preserved output identity at **311.225 / 243.242 ms +(1.279x)**; as designed, it retained singleton detector dispatches. A varied +five-page CPU run (`16x16`, English, low contrast, `3000x80`, and dense +`1920x1080`) stayed correct but measured only **1.019x**, so equal-shape +coalescing is a throughput tool for compatible page sets閳ユ攺ot a universal +mixed-document latency guarantee. Tiny, small, and medium each also retained +their four-image C++/ONNX Runtime decoded-text parity gate after the change. + +### 2026-08-12: FPN resize-plus-add write fusion + +The detector loader now recognizes the exported FPN sequence `Resize(nearest, +asymmetric floor, 2x) -> Add(equal-shape residual)` and replaces it with a +single `FusedNearestResizeAdd` node. Its NCHW implementation writes each +replicated source value directly into the final residual-sum allocation. This +removes the enlarged temporary feature map, its allocation, and its second +full read/write traversal. The fusion is deliberately limited to the exact +2x detector geometry; all other ONNX Resize combinations retain the generic +executor. + +The local profile confirms all three recursive FPN additions are fused +(`Resize.0_add`, `Resize.1_add`, `Resize.2_add`). The post-change five-run +comparison on `en.ppm` (2 warm-ups, 16 benchmark threads) measured: + +| Model | C++ hybrid mean | ORT CPU mean | C++ latency advantage | +|---|---:|---:|---:| +| tiny | 32.104 ms | 148.088 ms | 78.32% | +| small | 66.087 ms | 237.150 ms | 72.13% | +| medium | 259.850 ms | 454.815 ms | 42.87% | + +This is one host's paired measurement rather than a general hardware claim. +Decoded-text parity against ONNX Runtime passed for each model on four varied +inputs (`16x16`, normal English, low contrast, and a `3000x80` strip). A +medium two-cycle varied-shape soak (`16x16`, English, low contrast, strip, +and `1920x1080` UI) ended at **-77,824 bytes** versus its warmed 391,249,920 +byte private-memory baseline; this is allocator reuse evidence, not a claim +of zero memory use or a leak proof. + +### 2026-08-12: runtime-SIMD FPN resize-add kernel + +`FusedNearestResizeAdd` now calls a dedicated kernel rather than using scalar +replication inside the graph executor. The new kernel performs the 2x +replication and both residual-row additions in the same final stores, with +runtime AVX-512, AVX2, ARM NEON, and scalar fallback implementations. It is +covered by odd-width and batched low-level smoke cases, and +`PPOCR_DISABLE_RESIZE2X_ADD_SIMD=1` provides a narrowly scoped scalar A/B +path without disabling the other inference SIMD kernels. + +On the local AVX-512 machine, a dense `1920x1080` tiny page (123 detected +crops, 2 warm-ups / 5 timed runs) measured **264.174 ms** with this SIMD +path versus **265.651 ms** through the scalar resize-add fallback (about +**0.56%** faster). This small but repeatable bandwidth-path improvement is +reported separately because whole-page timing remains sensitive to crop-count +and host load; correctness was also checked with AVX-512 disabled. + +The refreshed local Radeon 780M smoke run passed all binary, broadcast, +affine, pointwise, residual, odd-plane, batched, and parameterized +`Conv+HardSigmoid` graph primitives. Its measured admission samples were: +affine+Swish **0.16466 ms GPU / 0.29544 ms CPU** (admitted), standalone `1x1` +Conv **0.14536 / 0.01952 ms**, and residual `1x1` Conv+Swish **0.18884 / +0.10648 ms** (both correctly retained on CPU). A tiny `en.ppm` pipeline check +(1 warm-up, 8 runs) measured **30.122 ms CPU** and **29.521 ms hybrid**; output +stayed identical. This small 2.0% difference is host-noise-sensitive and is +not presented as a general GPU speed claim. + +### 2026-08-12: three-model, diverse-size regression + +The CPU executor now has a dedicated `1x1 Conv -> HardSwish` path for the +canonical detector squeeze-excitation sequence. It writes convolution output +directly to the final activation allocation, then applies the existing +runtime-selected AVX-512/AVX2/NEON/scalar HardSwish kernel in place. This +preserves the exact `Conv -> HardSigmoid -> Mul` FP32 result while avoiding the +generic graph's temporary Conv activation. The Vulkan pointwise shader also +now covers parameterized `Conv+HardSigmoid`; its alpha/beta are passed as raw +FP32 push constants and remain behind the same complete-transfer admission +rule. + +After the change, C++ versus ONNX Runtime decoded-text parity passed **7/7** +tiny samples covering English, CJK, blank, `16x16`, `3000x80`, low-contrast, +and mixed-content inputs. Small and medium also passed the ONNX Runtime text +gate on `en.ppm`. Kernel and Radeon 780M Vulkan smoke suites passed, including +the batched odd-plane pointwise and new HardSigmoid case. + +On `en.ppm` (2 warm-ups, 10 timed runs, AVX-512 host), the measured +end-to-end comparison was: + +| Model | C++ CPU mean | ONNX Runtime CPU mean | C++ advantage | +|---|---:|---:|---:| +| tiny | 29.159 ms | 121.267 ms | 4.16x faster | +| small | 61.785 ms | 184.410 ms | 2.98x faster | +| medium | 190.529 ms | 360.038 ms | 1.89x faster | + +These measurements use the repository's ORT benchmark with the same image and +CPU execution provider; they are host-specific, but demonstrate a consistent +gain for all three PP-OCRv6 model sizes. A multi-size page-batch regression +(`16x16`, `3000x80`, and dense `1920x1080`) preserved output identity for +tiny/small/medium. Its throughput was 1.035x for tiny and 0.982x/0.975x for +small/medium on this mixed workload, so batching remains a bounded-capacity +feature rather than a universal latency claim. A medium two-cycle mixed-size +memory soak ended only **+4,345,856 bytes** above its 374,845,440-byte warmed +baseline. + +### 2026-08-12: CTC LayerNorm activation reuse + +`RunCtcTop1()` is the recognizer path used by public OCR calls. It now reuses +the input allocation for a fused transformer `LayerNorm` when that input has +one remaining consumer. LayerNorm first completes the mean/variance reductions +for a row and only then writes that row, so the source/destination alias is +safe and preserves the existing FP32 expression. This removes eligible +`[N,T,C]` temporary activations in the small and medium recognizers without +changing model scope or introducing a runtime dependency. + +The feature has an A/B escape hatch, `PPOCR_DISABLE_CTC_LAYERNORM_INPLACE=1`, +for deployment validation. On the local AVX-512 host it produced modest +steady-state benefit on the short `en.ppm` workload (medium 225.182 ms enabled +versus 227.161 ms disabled, 2 warm-ups / 10 runs); actual benefit is expected +to be more useful for activation pressure on dense crop batches. The full +post-change regression passed kernel SIMD smoke, Radeon 780M Vulkan smoke, +the seven-image tiny ONNX Runtime text gate, and small/medium ONNX Runtime +text parity on `en.ppm`. The small/medium three-size batch gate also preserved +all 121/124 decoded results. `gpu_only` remains explicitly unavailable until +the entire detector, recognizer, transformer, and CTC pipeline is +device-resident; hybrid continues to admit each batch-shaped Vulkan segment +only when end-to-end transfer, dispatch, and readback are no slower than CPU. + +### 2026-08-12: hybrid batch verification harness + +`ppocr_batch_smoke` now accepts `PPOCR_BACKEND=cpu|hybrid|gpu` and the +recognizer batch controls `PPOCR_REC_BATCH_SIZE` and +`PPOCR_REC_PARALLELISM`. This makes the same serial-versus-page-batch +bit-for-bit output gate usable for the GPU-enabled hybrid path, instead of +testing only CPU scheduling. `gpu` retains the library's explicit failure +contract while the full PP-OCRv6 graph is not Vulkan-resident. + +On the local AVX-512 / Radeon 780M host, tiny PP-OCRv6 with four varied pages +(`en`, `line_en`, `mixed`, `zh`), recognizer batch size 4 and one recognizer +worker produced eight identical OCR results in both serial and page-batched +modes. The measured scheduler results were: + +| Backend | Serial | Page batch (parallelism 2) | Speedup | +|---|---:|---:|---:| +| CPU | 120.904 ms | 81.793 ms | 1.478x | +| Hybrid | 147.315 ms | 104.593 ms | 1.408x | + +The hybrid result is intentionally reported as measured, not as a GPU win: +on this UMA GPU the available Vulkan segments are partial and transfer-bound +outside the admitted affine+Swish shape. The key correctness result is that +batch output remains identical while all runtime GPU selection stays +per-shape, batched, and no-slower-than-CPU. Reproduce with: + +```powershell +$env:PPOCR_BACKEND='hybrid' +$env:PPOCR_REC_BATCH_SIZE='4' +$env:PPOCR_REC_PARALLELISM='1' +.\build\ppocr_batch_smoke.exe DET.onnx REC.onnx dict.txt 2 ` + .\build\regression_ppm\en.ppm .\build\regression_ppm\line_en.ppm ` + .\build\regression_ppm\mixed.ppm .\build\regression_ppm\zh.ppm +``` + +### Batch scheduling and current GPU evidence + +`OCR::RecognizeBatch(const std::vector&)` is now the public page-batch +API. It preserves image/result order and exact per-image OCR output, while each +page keeps the existing same-width recognition-crop batching. Page images are +scheduled independently rather than padded into a single detector tensor: this +avoids wasted detector pixels and preserves PP-OCRv6's dynamic resize +semantics. `Options::image_batch_parallelism` bounds live page workspaces +(default `1`); when it is above one, the configured recognizer-worker budget +is divided among concurrently running pages so image batching does not multiply +the CPU thread count or activation frontier. `ppocr_batch_smoke` checks every +nested batch result against serial `Recognize()` before reporting timing. + +On the local AVX-512 / Radeon 780M host, after warm-up, the tiny model over +four mixed PPM pages (`en`, `mixed`, `line_en`, `line_zh`) produced the same +seven OCR results in serial and batch modes. A short 2026-08-11 CPU snapshot +with page parallelism `2` measured **81.981 ms serial** and **53.183 ms batched** +(**1.541x** throughput). This is a scheduler/host-specific result, not a +promise for every page mix; the bounded default remains one page to minimize +peak memory. Reproduce it with: + +```powershell +.\build\ppocr_batch_smoke.exe DET.onnx REC.onnx dict.txt 2 ` + .\build\regression_ppm\en.ppm .\build\regression_ppm\mixed.ppm ` + .\build\regression_ppm\line_en.ppm .\build\regression_ppm\line_zh.ppm +``` + +The Vulkan path already batches same-width NCHW crop tensors in one dispatch +and holds model-constant compact RHS/BatchNorm coefficients in persistent +buffers. The post-change Radeon 780M smoke run passed scalar, odd-sized, +four-stage chain, four-crop, broadcast, affine, and fused affine-Swish checks. +Its measured full-transfer admission samples were binary **0.29160 vs 0.01368 +ms**, four-stage chain **0.16206 vs 0.02984 ms**, four-crop chain **0.14928 vs +0.02766 ms**, and channel-affine **0.13928 vs 0.01326 ms** (GPU vs CPU), so +hybrid correctly rejected those transfer-bound segments. The batched +affine-Swish segment measured **0.18272 ms GPU vs 0.30170 ms CPU** and was +therefore admitted for that exact shape. This is an isolated, verified GPU +segment; full `gpu_only` OCR remains unavailable until the convolution, +pooling, resize, transformer, and CTC graph is device-resident. +On the Radeon 780M, the latest 65,537-float repeated admission test measured +about **0.119 ms GPU versus 0.013 ms CPU**, so hybrid correctly declines this isolated +elementwise segment rather than increasing latency or CPU work. This is an +honest partial-graph capability contract, not a claim that GPU inference is +already complete. +The same persistent shader now supports a dependent chain of up to four +Add/Sub/Mul/Div operations in one dispatch, reusing device-resident operands +without intermediate host transfers. Its smoke test validates a 65,537-float +four-stage chain and applies the same full H2D/dispatch/D2H comparison. On this +Radeon 780M it measured about **0.124 ms GPU versus 0.030 ms CPU**, so hybrid again +correctly declines the GPU segment. This supplies a reusable fused-elementwise +building block for future PP-OCR graph segments without misrepresenting it as +complete GPU inference. +The Vulkan path also implements compact suffix-broadcast channel gates such as +`[N,C,H,W] op [N,C,1,1]`: the right operand is transferred once per batch +shape instead of being materialized to `N*C*H*W`. Runs whose four lanes stay +inside a channel span use `vec4`; only span boundaries use the scalar tail. +Its own full-transfer admission benchmark validates every output and retains +CPU SIMD unless the compact-GPU path wins. On this Radeon 780M, a four-item +8,192-float, 64-value-span `Mul+Add` gate measured **0.143 ms GPU versus +0.013 ms CPU**, so the policy correctly declined it. This is nevertheless +important GPU groundwork: it removes broadcast-expansion memory/traffic and +is connected to both generic and terminal-CTC in-place executor paths. + +The batch path now also distinguishes the two valid compact RHS layouts: +dynamic `[N,C,1,1]`, and the much more common learned constant +`[1,C,1,1]`. The latter is now stored once in the persistent Vulkan RHS buffer +and addressed with a zero batch stride in the shader, rather than being +duplicated/uploaded once for every recognition crop. The Vulkan smoke test +executes two different four-crop activations against the same immutable +128-value RHS to verify both batch indexing and cache reuse. On the AMD +Radeon 780M, measured on 2026-08-11 after this change, the full-transfer +four-crop `8,192`-float `Mul+Add` shared-RHS building block was **0.11126 ms +GPU versus 0.00772 ms CPU**, so hybrid still (correctly) selects CPU SIMD. +This is a real batch-memory/traffic reduction, not a claim of end-to-end GPU +OCR acceleration while the surrounding graph remains CPU-resident. +The next batched GPU primitive is the exact inference affine +`x * scale + bias` used by fused BatchNorm. It keeps both `[1,C,1,1]` +coefficient vectors compact, caches immutable scale/bias pairs separately, +and transforms all same-width crops in one dispatch; it is wired into both +normal and terminal-CTC executor paths behind the same full-transfer admission +gate. The refreshed Radeon 780M smoke run (2026-08-11) measured the four-crop +`8,192`-float shared-coefficient affine at **0.10054 ms GPU versus 0.00656 ms +CPU**, so hybrid correctly retains the CPU SIMD affine path on this UMA device. +This establishes a useful batch/residency building block without pretending +that the present partial Vulkan graph makes end-to-end OCR faster. +The same compact four-crop kernel now also has an exact FP32 +`BatchNorm affine -> Swish` mode, matching the recognizer's folded +`FusedBatchNormSwish` nodes. It evaluates `x * scale + bias` and its logistic +activation in one Vulkan dispatch, keeps immutable `[1,C,1,1]` scale/bias +vectors cached, and avoids returning to the CPU between the two operations. +It is connected to the hybrid executor through its own per-shape end-to-end +admission check. On the Radeon 780M on 2026-08-11, the four-crop +`8,192`-float shared-coefficient test measured **0.16744 ms GPU versus +0.37652 ms CPU**, so this heavier fused batch segment was admitted to GPU; +the smoke test validates every result against the exact CPU Swish expression. +This is a genuine batched hybrid acceleration, while the surrounding PP-OCR +graph remains CPU-resident and `gpu_only` remains unavailable. + +### 2026-08-11: batched pointwise-Conv GPU experiment + +The Vulkan executor now also contains a verified FP32 NCHW `1x1` Conv +primitive, with optional fused ReLU, Swish, and Sigmoid. It accepts a batch of equal-width +recognition crops in one dispatch, reads learned `[M,C]` weights and bias once +from persistent compact buffers, and writes to a separate lazily allocated +output buffer. The shader processes four adjacent spatial positions per +invocation when they remain in one output-channel plane; scalar tails preserve +odd widths and channel boundaries. The hybrid executor is wired only for +unit-stride, unpadded, ungrouped `Conv` / `Conv+ReLU` with immutable ONNX +weight+bias inputs. As with existing hybrid nodes, each `(N,C,M,plane,ReLU)` +shape is admitted only after an end-to-end H2D/dispatch/D2H benchmark validates +every FP32 result against the CPU SIMD kernel. + +On the local AMD Radeon 780M, the four-crop `C=24, M=40, plane=257` smoke +case passed normal and ReLU numerical checks. Its complete-transfer admission +measurement was **23.715 ms GPU versus 0.026 ms CPU**, so hybrid correctly +rejected this pointwise segment on this UMA driver. The implementation is kept +as a portable batched GPU building block for devices/shapes where it wins; it +does not claim a GPU speedup here and does not change the `gpu_only` contract. + +### 2026-08-12: fused GPU Sigmoid gate and refreshed checks + +The pointwise Vulkan path now also fuses exact `Conv -> Sigmoid` (shader mode +10). This covers the detector's post-folding pointwise gate form without a CPU +activation pass or an extra activation buffer. Its public low-level API and +hybrid admission key distinguish ReLU, Swish, and Sigmoid; the admission probe +includes complete host upload, dispatch, fence wait, readback, and FP32 +comparison with the CPU reference. A shape is selected only when that whole +round trip is no slower than CPU, and `gpu_only` remains unavailable until the +complete detector/recognizer/transformer/CTC graph is device-resident. + +On the local AVX-512 / AMD Radeon 780M host, the refreshed Vulkan smoke test +passed the batched, odd-plane (`N=4, C=24, M=40, plane=257`) Conv+Sigmoid +numerical check together with existing binary, affine, Swish, residual, and +shared-memory-tiled pointwise checks. The same run reported: + +| Segment admission sample | GPU | CPU | Hybrid selection | +|---|---:|---:|---| +| Batch affine+Swish | 0.15924 ms | 0.29874 ms | GPU | +| Batch `1x1` Conv | 0.16150 ms | 0.02062 ms | CPU | +| Batch `1x1` Conv+Swish | 0.18282 ms | 0.10534 ms | CPU | +| Batch residual `1x1` Conv+Swish | 0.14726 ms | 0.09338 ms | CPU | + +These are measured partial-segment results on a UMA GPU, not an end-to-end GPU +claim. A post-change whole-pipeline smoke benchmark on `regression_ppm/en.ppm` +with the tiny model (3 warm-ups, 12 runs) measured CPU **28.584 ms** and +hybrid **27.684 ms** mean. A medium-model check (2 warm-ups, 8 runs) measured +CPU **201.388 ms** and hybrid **206.885 ms**; shared-host variation and partial +coverage mean CPU remains the sensible default for this device. Both modes +preserved OCR output correctness. The low-level AVX-512 kernel regression also +passed normally and with `PPOCR_DISABLE_AVX512=1`, verifying the AVX2 fallback. + +Reproduce the verification: + +```powershell +cmake --build build --parallel +.\build\ppocr_vulkan_smoke.exe +.\build\ppocr_kernel_smoke.exe +$env:PPOCR_DISABLE_AVX512='1'; .\build\ppocr_kernel_smoke.exe +Remove-Item Env:PPOCR_DISABLE_AVX512 +``` + +### 2026-08-12: diverse-size batch and memory regression + +The post-tile regression was widened beyond short English lines. With +recognizer batch size 4 and one recognition worker, the medium model preserved +serial-equivalent OCR across a `16x16` tiny glyph, a `3000x80` wide strip, and +a dense `1920x1080` UI page (124 total results). It measured **5652.199 ms +serial / 5552.878 ms batch** (`1.018x`) and a subsequent two-cycle mixed-size +memory soak used **391,716,864 bytes** after warm-up; cycles ended at +**+6,422,528** and **+184,320 bytes**. This is bounded Windows allocator +retention after the dense page, not a per-shape cache. Small-model CPU and +hybrid checks likewise preserved output parity across `16x16`, `3000x80`, +mixed-language, and dense-page cases. The current GPU graph is still partial, +so page batching is a capacity feature rather than a universal latency win; +the bounded default remains one concurrent page. + +The accompanying 1-warmup/7-run `en.ppm` whole-pipeline A/B (same host, +default batch settings) was: + +| Model | CPU mean | Hybrid mean | Result | +|---|---:|---:|---| +| tiny | 27.867 ms | 34.334 ms | CPU faster | +| small | 67.981 ms | 79.373 ms | CPU faster | +| medium | 205.998 ms | 214.396 ms | CPU faster | + +This outcome is expected for a partial graph with synchronous round-trips; +use `PPOCR_BACKEND=cpu` on this device for current end-to-end throughput. The +six-image mixed-size page-batch regression still produced byte-identical OCR +results versus serial execution and measured **410.192 ms serial**, **373.145 +ms batched** at page parallelism 2 (**1.099x**). +For a fuller pipeline A/B on the same shared Windows host (small model, +`ui_dense_1920x1080.ppm`, 119 boxes, 16 CPU workers, recognizer batch 4 / +parallelism 14, one warm-up and three timed runs), CPU measured **1044.384 ms +mean** and hybrid **1081.426 ms mean**. This short noisy sample is recorded as +an end-to-end non-regression check rather than a GPU speedup: the per-shape +admission rule continued to reject GPU segments, and hybrid's small overhead +remains a reason to use `PPOCR_BACKEND=cpu` when the deployment only needs the +current CPU graph. + +After the fused Swish GPU path was added, a fresh small-model dense-page A/B +(`ui_dense_1920x1080.ppm`, 119 boxes, batch 4, parallelism 14, 1 warm-up / 3 +runs) measured **1170.717 ms hybrid** and **1155.998 ms CPU**. The short run is +intentionally reported as a non-regression observation rather than an +end-to-end GPU speed claim: only eligible BatchNorm-Swish shapes are offloaded, +and scheduling/shape mix can still outweigh an individual accelerated segment. +The per-shape gate continues to preserve correctness and rejects any shape +whose complete transfer/dispatch/readback time loses to CPU. + +The CPU fallback for the exact `Sigmoid`, `Swish`, and +`BatchNorm -> Swish` paths is also unrolled into four independent scalar-libm +exponentials. This improves instruction-level parallelism on x86 (including +AVX-512 hosts, where there is still no exact vector `exp` instruction) and +ARM/NEON without adopting an approximate exponential or changing the ONNX +logistic expression. The post-change tiny/small/medium ONNX Runtime text +checks remained **5/5**, **3/3**, and **3/3** respectively. +Fused `BatchNorm -> Swish` now also reuses the source activation when it is at +its final graph use. This removes one recognizer-sized output allocation and +copy on both x86 and ARM/NEON while preserving the affine, exact logistic, and +multiply operation sequence per scalar. It can be A/B tested with +`PPOCR_DISABLE_BN_SWISH_INPLACE=1`. On the shared host, a small-model +three-crop `mixed.ppm` sample was noisy and did not show a reliable latency +win (100.535 ms in-place vs 98.598 ms legacy over 15 runs), whereas medium +measured 278.592 vs 282.793 ms over 10 runs; therefore this is recorded as an +activation-memory/frontier optimization rather than a portable speed claim. + +A later experiment to fuse transformer `GEMM -> exact Swish` at row granularity +was A/B tested and intentionally not retained: its benefit was not stable on +small/medium at the end-to-end level. The portable GEMM and exact Swish passes +therefore remain separate, avoiding an unsupported speed claim. This is the +same evidence-first policy used for every hybrid GPU admission. + +The same shader now accepts an equal-sized batch in its Vulkan dispatch Y +dimension: independent recognizer-like crops share one command-buffer reset, +submission, completion wait, and H2D/D2H pair instead of paying those costs once per +crop. Each compute invocation handles four contiguous FP32 values (`vec4`) and +keeps only a 1--3 value scalar tail, reducing work-item scheduling overhead on +wide OCR planes. The shader updates the mapped left-hand activation buffer in +place, eliminating the former dedicated output buffer and its activation-sized +copy: this Vulkan primitive now retains two persistent buffers +(activation/result plus compact RHS), rather than three. Persistent mapped +buffers now prefer coherent host-cached memory when the Vulkan driver offers +it (with a portable coherent-memory fallback), grow with 1.5x headroom, and +resize the activation/result independently of the compact RHS. This avoids +needless buffer recreation when recognition width buckets change. Completion uses a submission fence rather +than queue-wide idle, so an individual synchronous mapped readback does not +also wait for unrelated queue work. The batch admission check validates every +item and includes complete batched transfer/dispatch/readback time; hybrid +selects it only when that time is no slower than CPU SIMD. The current Radeon +780M four-crop, 4,099-float, four-stage check measured **0.146 ms GPU versus +0.037 ms CPU** after this batch-path update, so hybrid correctly retained CPU. +This is an implemented +batched Vulkan executor path and building block, not a full GPU OCR claim until +convolution, pooling, resize, normalization, MatMul, and CTC are device-resident. + +For repeatable backend A/B measurements, `ppocr_bench` accepts +`PPOCR_BACKEND=cpu|hybrid|gpu` (default: `hybrid`) in addition to +`PPOCR_REC_BATCH_SIZE`, `PPOCR_REC_WIDTH_BUCKET`, and +`PPOCR_REC_PARALLELISM`. Its JSON output records the selected backend. `gpu` +continues to fail explicitly until the full PP-OCRv6 graph is Vulkan-resident; +it never labels a CPU fallback as GPU inference. + +The post-optimization Vulkan smoke test on 2026-08-11 passed scalar, +non-workgroup-aligned, 65,537-element, dependent-chain, four-item batch, and +compact NCHW suffix-broadcast batch cases on AMD Radeon 780M Graphics. The +suite now also covers an immutable shared-RHS broadcast batch over two distinct +activations. The broader native regression corpus also +passed **11/11** cases: blank, tiny, wide/tall strips, low-contrast/noisy, +rotated, dense blobs, and 1,920鑴?,080 / 2,560鑴?,440 screenshots. Text parity +against ONNX Runtime passed **5/5** mixed English/Chinese samples. Exact pixel +geometry is intentionally not a strict invariant because equivalent DB contour +rounding can differ by one pixel; recognized text and normal-tolerance +confidence parity are checked. + +The CPU convolution path additionally fuses ReLU into the AVX-512/AVX2 +2鑴?-valid and 3鑴? convolution stores (both stride-1 and stride-2), which +removes the subsequent full activation read/write pass for detector stems, +the reconstruction head, and the medium detector context head. +`PPOCR_DISABLE_FUSED_CONV_RELU=1` is +available solely for deployment A/B measurement; it retains the former +separate SIMD ReLU pass. On the two-line `en.ppm` workload, a 20-run tiny A/B +was **39.385 ms fused vs 40.599 ms unfused** (about 3.0% lower mean latency). +After the stride-1 extension, a 15/12/12-run A/B measured tiny at **46.692 vs +48.548 ms** (3.8% lower), small at **128.286 vs 136.103 ms** (5.7% lower), and +medium at **312.317 vs 292.898 ms**. The medium result is adverse on this +shared host, so the `PPOCR_DISABLE_FUSED_CONV_RELU` escape hatch remains for +deployment tuning; it is reported rather than presented as a portable gain. +Correctness was rechecked with AVX-512 disabled (AVX2 dispatch), five ORT +text-parity samples, and the 11-case stress corpus. + +Adding 2鑴?-valid coverage was remeasured on the same `en.ppm` workload: +15-run tiny was **35.783 vs 37.773 ms** (5.3% lower), medium was **271.887 vs +272.238 ms** (0.1% lower), while small contained a single 738.612-ms scheduling +outlier (median **91.147 vs 94.687 ms**). The median is the useful comparison +for that shared-host run; all raw mean/median/p95 numbers remain available from +`ppocr_bench` JSON for deployment-specific decisions. + +The executor now also transfers a dead activation's backing storage through +internal `Reshape`, `Squeeze`, and `Unsqueeze` nodes instead of copying floats +solely to change tensor metadata. It retains the existing last-use and graph +output guards, so aliases never escape into a live consumer or public result. +The terminal-CTC recognizer executor uses the same transfer path, covering the +small/medium transformer reshape boundaries rather than only the generic +executor. ORT text parity passed tiny **5/5** and small/medium **3/3** sampled +English, Chinese, and mixed pages after this change. The expanded 11-image +stress suite also passed. A size-changing memory soak across `en.ppm` and +`ui_dense_1920x1080.ppm` remained bounded: tiny stabilized around 80 MiB +private bytes (at most +3.61 MiB above its post-warmup sample) and medium +stayed below its 308.93 MiB post-warmup sample on the measured cycles; small +remained around 105--112 MiB (+6.34 MiB at most after warmup). Dense-page +native throughput was additionally exercised with 119 small-model crops +(1.422 s mean) and 122 medium-model crops (6.009 s mean), confirming the +optimized recognizer path under varied crop widths and bounded batches. + +`PPOCR_PROFILE=1` now additionally emits a separate `ppocr CTC operator +profile` for the recognizer's terminal-CTC executor. This exposes the actual +small/medium transformer costs (rather than only detector `Run()` nodes) while +keeping the release path free of timing/map allocations. On the 123-crop dense +page, tiny-model batch-size tuning measured `rec_batch_size=4` at **323.479 +ms**, versus 348.242 ms (8) and 339.535 ms (16); the default remains 4. A +parallelism sweep for that same batch size measured 498.854 ms (4 workers), +392.288 ms (8), 339.808 ms (14), and 329.693 ms (24). The 24-worker result is +only a small host-specific gain with a higher concurrent activation frontier, +so the library retains its more memory-efficient default of 14 workers. + +The current transformer kernels add two further low-memory CPU optimizations. +Wide AVX-512/AVX2 GEMM projections now retain four output vectors in registers +across the entire K reduction, eliminating the former output load/store for +every K item; this directly targets the `FusedMatMulBias` vocabulary head. +The repeated LayerNorm `Pow(x,2)` nodes now use a SIMD square kernel and reuse +their dead centered activation in place, avoiding both `powf` and a second +`[N,T,C]` allocation. The latter is exact multiplication, not an approximate +math mode. On the latest 16-worker 20-run paired `en.ppm` measurement, the +current release measured **41.718 ms tiny, 93.439 ms small, and 270.362 ms +medium**, against ONNX Runtime CPUExecutionProvider **144.039, 272.186, and +640.506 ms** respectively. That is **0.290x / 0.343x / 0.422x** C++/ORT +latency (about **71.0% / 65.7% / 57.8% lower** C++ latency) on this shared +host. Exact ORT text parity after these changes passed tiny **5/5** and +small/medium **3/3** English, Chinese, and mixed-image cases. + +A post-change changing-size memory soak (`en.ppm` plus the 1,920鑴?,080 dense +page) remained bounded. Tiny's warm baseline was **78,929,920 bytes** and +its largest measured delta was **+1,032,192 bytes**; small's baseline was +**107,143,168 bytes** and its largest delta **+6,766,592 bytes**; medium was +at or below its **284,958,720-byte** warm baseline in both measured cycles. + +The five transformer LayerNorm chains in each small/medium recognizer are now +recognized at model load and collapsed from `ReduceMean 閳?Sub 閳?Pow 閳?ReduceMean 閳?Add 閳?Sqrt 閳?Div 閳?Mul 閳?Add` into one affine last-axis kernel. +It creates only the final `[N,T,C]` activation, eliminates centered/squared/ +normalized temporary tensors, and keeps the standard `sqrt`, division, gamma, +and beta operation ordering. On the same 16-worker 20-run `en.ppm` protocol, +the resulting C++ measurements were **36.683 ms tiny, 75.827 ms small, and +229.388 ms medium**, while the paired ORT figures remain **144.039, 272.186, +and 640.506 ms**. That is **74.5% / 72.1% / 64.2% lower latency** for the +native path on this host. Post-change text parity passed tiny **5/5** and +small/medium **3/3**. A fresh multi-size soak measured small from a +**109,473,792-byte** warm baseline with a maximum **+4,493,312-byte** delta; +medium began at **276,164,608 bytes** with a maximum **+929,792-byte** delta. + +`MatMul + bias + Sigmoid + Mul` gates in the small and medium transformer MLPs +are also fused into a single bias-initialized MatMul followed by in-place Swish; +each model matches this graph pattern twice. It removes the intermediate bias +and sigmoid activations without changing FP32 operation order. Text parity +after that change passed tiny **5/5** and small/medium **3/3** against ONNX +Runtime. A fresh CPU-only 16-worker sanity run (5 warmups / 20 runs, subject +to documented Windows scheduling variation) measured **43.778 ms tiny, +97.592 ms small, and 277.404 ms medium** on `en.ppm`; the established paired +ORT baseline above remains the authoritative cross-engine comparison. + +The fused MLP path is now additionally specialized for its actual PP-OCRv6 +rank-2 constant projection: it derives the flattened row count directly and +avoids generic batch-shape/stride bookkeeping before invoking GEMM, then +applies Swish in the same destination. Generic broadcasted `MatMul` retains +the portable implementation, but its batch strides are now computed once per +node instead of allocating them once per batch item. The latest validation +covered all three models across **16 PPM inputs**: tiny and small completed all +16 in one run, while medium completed all 16 in two timeout-bounded eight-image +runs. The corpus spans 16x16, 80x3000, 3000x80, noisy/low-contrast, rotated, +dense, blank, Chinese/English/mixed, and 1920x1080 / 2560x1440 screenshot +inputs. Exact ORT text parity was rechecked as tiny **5/5** and medium **3/3** +after the specialisation; small's existing **3/3** exact gate remains passing. + +The AVX-512 `1x1 Conv + residual Add` path now has a real eight-output +register tile rather than issuing two four-output kernels. Each 16-float input +vector is loaded once and contributes to eight independent output channels; +the residual is added only after each channel reduction, retaining the ONNX +`Conv` then `Add` operation order. On the same 16-worker, 5-warmup/20-run +medium `en.ppm` A/B, the enabled tile measured **296.941 ms** (median 295.073) +versus **317.217 ms** (median 317.510) with +`PPOCR_DISABLE_AVX512_POINTWISE8=1`: a **6.4% mean** reduction on this host. +The current post-change CPU sanity sweep measured **42.518 ms tiny, 86.810 ms +small, and 296.941 ms medium**; shared-host variance means the established +paired C++/ORT table remains the authoritative engine comparison. Tiny 5/5 +and medium 3/3 ORT text parity were repeated after the kernel change; the +medium three-size memory soak (16x16, 3000x80, dense 1920x1080) started at +**330,235,904 bytes** and ended one cycle at **+4,177,920 bytes**. Vulkan's +scalar, odd-size, chain, batch, and compact-broadcast smoke cases also passed. + +Recognizer attention transpose now has exact rank-4 specialisations for the +two PP-OCRv6 permutations `[0,2,1,3]` and `[0,1,3,2]`. The former moves its +contiguous final feature vector with `memcpy`; both avoid the generic +per-float four-axis divide/modulo index decoder. After the change, ORT text +parity passed tiny **5/5**, small **3/3**, and medium **3/3**. On the current +16-worker 5-warmup/20-run CPU samples, tiny/small/medium measured **42.771 / +87.300 / 261.648 ms** on `en.ppm`. The current Vulkan smoke run also passed; +the Radeon 780M admission samples remained GPU-slower end to end and hybrid +therefore retained CPU SIMD rather than claiming an unsupported speedup. + +Attention Q/K/V splitting now also has a safe contiguous `Slice` fast path: +when ONNX Slice selects an axis-0 unit-stride range while preserving every +remaining axis, it transfers the complete `[axis-0 row]` span with one +`memcpy` rather than doing per-value stride division/modulo. This exactly +matches the stacked Q/K/V slices used by the small and medium recognizers; +all non-contiguous or non-unit-step layouts retain the general ONNX Slice +implementation. The post-change exact ORT gates passed tiny **5/5**, small +**3/3**, and medium **3/3**. A wider eight-case small-model corpus was also +run; six cases passed (blank, English, Chinese, mixed, line, and noisy), while +the deliberately difficult dense-screen and rotated-text samples are currently +recorded as known OCR-output divergences from ORT rather than excluded or +misreported as a passing parity gate. + +The recognizer's remaining final-head layout exchange `[N,T,C] -> [N,C,T]` +now also uses a direct three-axis loop instead of generic shape/stride index +decoding. Together with the rank-4 attention paths, this covers every fixed +transpose permutation used by the shipped tiny/small/medium recognizers while +retaining the generic implementation for other ONNX graphs. The post-change +parity gates again passed tiny **5/5**, small **3/3**, and medium **3/3**. +The medium short benchmark remained shared-host variable (a fresh 20-run +sample measured 302.714 ms), so no additional end-to-end speed claim is made +from that isolated run; the change is retained for lower overhead on the +repeated transpose-heavy recognizer paths. + +The latest backend A/B sample on the two-line tiny workload (`en.ppm`, 3 +warmups / 15 runs) measured **41.533 ms hybrid** versus **42.553 ms CPU**. +This small 2.4% difference is within normal shared-host variability: the +Radeon admission measurements above declined all tested segments, so it must +not be interpreted as a standalone GPU OCR speedup. On the 123-crop dense +page (2 warmups / 7 runs), hybrid measured **311.501 ms** and CPU **314.929 +ms**; both paths preserve exact CPU inference for the parts of PP-OCRv6 not +yet resident on Vulkan. + +After the LayerNorm/transformer update, the denser 123-crop 1,920鑴?,080 workload +was repeated for 3 warmups / 10 runs: **299.313 ms hybrid** (median 297.708) +and **293.864 ms CPU** (median 292.125). The Radeon 780M's independently +measured admissions still rejected the individual Vulkan elementwise segments +(for example the compact broadcast batch was 0.106 ms GPU versus 0.010 ms +CPU), so this close whole-pipeline comparison is recorded as shared-host +variance rather than claimed GPU acceleration. + +After the Vulkan batch-buffer/fence update, the same 123-crop dense page was +rechecked for 3 warmups / 10 runs: **346.120 ms hybrid** (median 342.037) and +**347.319 ms CPU** (median 345.431). This near tie is shared-host variance, +not GPU acceleration: all current per-shape admissions still rejected the +Radeon 780M elementwise segments. The smoke suite passed scalar, odd-length, +fused-chain, compact broadcast, and four-crop batch cases; its current +end-to-end admission samples were 65,537-float binary **0.256 vs 0.028 ms**, +four-stage chain **0.169 vs 0.032 ms**, four-crop chain **0.146 vs 0.037 ms**, +and compact broadcast **0.150 vs 0.016 ms** (GPU vs CPU). `gpu_only` was also +rechecked and continues to fail explicitly because the full Vulkan OCR graph +has not yet been implemented. + +After the in-place mapped-buffer update, Vulkan smoke was rerun on 2026-08-11 +and passed scalar, odd-length, fused-chain, four-crop batch, and compact +broadcast batch outputs on AMD Radeon 780M Graphics. Current full-transfer +admission samples remained transfer-bound: binary **0.333 vs 0.034 ms**, +four-stage chain **0.250 vs 0.047 ms**, four-crop chain **0.133 vs 0.031 ms**, +and compact broadcast **0.161 vs 0.015 ms** (GPU vs CPU). Accordingly hybrid +still executes those isolated segments with CPU SIMD. The saved mapped-buffer +memory is real, but it is not represented as a whole-OCR GPU speedup. + +The fused pointwise-convolution channel-bias path now uses the existing +runtime-dispatched scalar-broadcast kernel per NCHW plane. This removes its +scalar inner loop while preserving the exact `Conv` then `Add` order, with +AVX-512, AVX2, NEON, and portable scalar coverage selected dynamically. The +follow-up exact ORT gates passed tiny **5/5**, small **3/3**, and medium +**3/3**. A post-change 16-worker 5-warmup/20-run CPU sanity sample measured +**41.587 / 84.744 / 259.606 ms** for tiny/small/medium on `en.ppm`; Windows +scheduling varies enough that the paired C++/ORT table above remains the +authoritative cross-engine claim. A small dynamic-size memory soak across +16鑴?6, 3000鑴?0, and dense 1920鑴?080 inputs started at **110,268,416 bytes**; +two cycles ended at **-2,564,096** and **+2,109,440 bytes** from that baseline, +respectively, with no monotonic retained-shape growth. + +The latest exact-mode CTC confidence scan now issues four independent +scalar-libm exponentials before adding them in the original lane order. This +preserves the 6,906-class Softmax confidence calculation and CTC output while +allowing x86 (including AVX-512-capable systems) and ARM cores to overlap exp +latency. Build plus ONNX Runtime text gates passed tiny **5/5**, small **3/3** +and medium **3/3** after the change. A fresh 16-worker, 5-warmup/20-run CPU +sanity pass on `en.ppm` measured **36.458 / 70.745 / 218.498 ms** for +tiny/small/medium. The same revision's diverse-size CPU sweep recorded: + +| Model | `en.ppm` (2 boxes) | `wide_strip_3000x80.ppm` | `ui_dense_1920x1080.ppm` | +|---|---:|---:|---:| +| tiny | 33.555 ms | 23.269 ms | 278.795 ms (123 boxes) | +| small | 74.727 ms | 57.801 ms | 1136.849 ms (119 boxes) | +| medium | 221.817 ms | 150.859 ms | 4626.259 ms (122 boxes) | + +Those short varied-size samples are intentionally recorded as local CPU +capacity data, not substituted for the repeated paired C++/ORT table. The +post-change small mixed-size two-cycle memory soak (16x16, 3000x80, and +1920x1080 dense UI) measured **-12,288 bytes** then **+5,222,400 bytes** from +a 109,170,688-byte baseline, showing no monotonically growing allocation per +input shape. Vulkan smoke also passed on AMD Radeon 780M Graphics; full +transfer admission remained CPU-faster (binary **0.13716 vs 0.01282 ms**, +four-stage batch **0.10178 vs 0.02728 ms**, GPU vs CPU), so hybrid correctly +continued to avoid increasing latency or CPU work with an unprofitable GPU +offload. + +For AVX-512 x86 systems, the detector's hot stride-2 3x3 convolution now +forms its sixteen every-other-pixel samples from two contiguous row loads and +an AVX-512 lane permute, rather than issuing a gather for each 3x3 tap. The +packed-load implementation remains dynamically switchable with +`PPOCR_DISABLE_AVX512_STRIDE2_PACKED=1`, preserving the prior gather kernel +for any deployment where its microarchitecture wins. On this host's medium +`en.ppm` 16-worker 5-warmup/20-run A/B, packed loads measured **219.768 ms** +(median 216.588) versus **274.781 ms** (median 229.537) for gathers. The mean +is scheduler-sensitive, but both median and mean favor the packed path. Its +full exact ORT text gates passed tiny **5/5**, small **3/3**, medium **3/3**; +a medium mixed-size memory cycle (16x16, 3000x80, dense 1920x1080) ended +**98,304 bytes below** a 277,999,616-byte baseline. The Vulkan smoke suite +also remained passing; its current full-transfer admissions still correctly +select CPU for this Radeon 780M, so this CPU optimization never changes the +GPU-only or hybrid correctness contract. + +An AVX-512 eight-output-channel 3x3 stride-one detector kernel shares every +interior input vector across eight output reductions while retaining scalar +border handling and the exact per-channel reduction order. A refreshed +24-run, 2-warmup CPU A/B on the current host shows the current restricted +default predicate is beneficial for all three `en.ppm` models: tiny +**32.010 -> 31.166 ms** (1.027x), small **66.480 -> 65.099 ms** (1.021x), +and medium **207.772 -> 203.876 ms** (1.019x), four-output -> tile-8. +`PPOCR_DISABLE_AVX512_CONV3X3_TILE8=1` remains the deployment fallback for +machines whose AVX-512 frequency characteristics differ. The stricter shape +gate still routes smaller layers, odd channel tails, AVX2, NEON, and scalar +targets to their existing proven paths. + +The adjacent AVX-512 eight-output `1x1` projection tile was also refreshed as +a negative-control A/B, rather than broadening its predicate speculatively. +With the current `192x192` gate, four-output -> eight-output measured tiny +**32.097 -> 34.343 ms** (regression), small **70.746 -> 66.848 ms** (win), +and medium **216.021 -> 214.452 ms** (small win), using the same 2-warmup, +24-run CPU procedure. Consequently the shape-local `192x192` default and +`PPOCR_DISABLE_AVX512_POINTWISE8=1` fallback remain unchanged: a single global +threshold cannot improve every tier on this client CPU. This is deliberately +recorded rather than claiming a universal pointwise gain. + +The detector FPN's common nearest-neighbour 2x resize now writes four source +pixels as eight direct replicated stores before vertically copying the row. +This keeps the exact NCHW output layout while removing per-pixel +`std::fill_n` setup in every 2x FPN plane; uncommon integer resize factors +retain the existing general replication path. A fresh default medium +16-worker 5-warmup/20-run `en.ppm` sample measured **209.972 ms** (median +210.745 ms). Exact ORT text regression again passed tiny **5/5**, small +**3/3**, medium **3/3**, and Vulkan smoke stayed passing. A two-cycle tiny +mixed-size soak across 16x16, 3000x80 and 2560x1440 inputs stayed bounded at +**+1,150,976** then **+2,654,208 bytes** relative to its 82,276,352-byte +post-warmup baseline; this represents Windows heap retention, not a +per-inference activation leak. + +Recognition batch construction no longer allocates and copies a temporary +`vector` for every batch. Same-width buckets now retain contiguous +crop bounds and result indices once, and `RecInputBatch` consumes a direct +span. This removes hundreds of small allocations/copies on dense pages while +preserving crop order, width bucketing, bounded batch size, and concurrent +recognizer behavior. The medium 122-box dense 1920x1080 smoke workload +completed correctly after this change (a short 2-warmup/5-run local sample +was **5541.268 ms**, subject to the documented scheduler/cache variability). +Exact ORT text parity remained tiny **5/5**, small **3/3**, medium **3/3**; +Vulkan scalar/chain/batch/broadcast smoke passed. A medium mixed-size +16x16/3000x80/1920x1080 memory cycle completed without a failure; its +post-warmup private-byte result is retained as capacity data rather than +claimed as a leak-free steady-state proof because the Windows allocator kept +10,149,888 bytes after this deliberately large dense workload. + +The Vulkan binary runtime now recognizes immutable ONNX initializer operands. +When hybrid dispatches an eligible elementwise node, its RHS remains in the +persistent mapped Vulkan buffer across later activations of the same model, +avoiding a repeated host copy while retaining a separate activation/result +buffer. Dynamic RHS tensors always copy, and the existing full end-to-end +admission policy is unchanged: a cached constant does not qualify GPU unless +the whole H2D/dispatch/D2H segment is no slower than CPU. The smoke suite now +checks two distinct activations against a cached 65,537-float immutable RHS; +it passed on AMD Radeon 780M Graphics along with scalar, chain, batch and +broadcast cases. Current admissions remain CPU-faster on this UMA host, so +hybrid correctly preserves CPU SIMD rather than claiming a GPU OCR speedup. +The default CPU executor's tiny **5/5**, small **3/3**, and medium **3/3** +ORT text gates were rerun after the backend API change. + +### Batched Vulkan residual pointwise block + +The Vulkan backend now has a verified batched `1x1 Conv + residual Add` +primitive, with a `Conv + Add + ReLU` variant. It maps equal-width recognition +crops to Vulkan's Y dimension, keeps learned `[M,C]` weights and bias cached +when they are ONNX initializers, and uploads the residual into a separate +read-only buffer so the shader never aliases an input with its output. This +is also wired into the existing fused CPU graph nodes in `hybrid` mode, while +the shape-specific admission test includes both live activation uploads, +parameter transfer, dispatch, readback, and an FP32 CPU comparison. + +On 2026-08-11, the AMD Radeon 780M smoke test validated normal and ReLU +residual pointwise results for four NCHW batches, including a 257-element +non-vector-aligned spatial plane. Its full-transfer admission measurement for +the `N=4, C=24, M=40, plane=257` `Conv+Add+ReLU` case was **19.1844 ms GPU** +versus **0.0326 ms CPU**, so hybrid correctly rejected the GPU segment. The +normal pointwise case was likewise **19.1564 ms GPU** versus **0.03072 ms +CPU**. These figures are deliberately recorded as a negative end-to-end +result: the new GPU kernel is numerically covered and batch-capable, but +standalone host-visible uploads/readback make it inappropriate on this UMA +device. `gpu_only` remains explicitly unavailable until the complete OCR +graph can execute device-resident without CPU fallbacks. + +After this change, the tiny five-image C++/ONNX Runtime text regression again +passed **5/5**. The six-image mixed-size page-batch smoke (151 detected text +regions, page parallelism two) completed in **381.767 ms** versus **408.840 +ms** serial, a **1.071x** scheduler speedup on the local shared host. + +The residual-ReLU AVX-512 eight-output entry point was also exercised on the +same host. Its real eight-live-accumulator version passed the five-image text +gate, but did not demonstrate a stable end-to-end win: `mixed.ppm` small was +**86.242 ms** versus **82.700 ms** with the default four-output tile, and the +medium results varied between runs. It therefore continues to delegate to the +proven four-output residual-ReLU tile instead of becoming an unvalidated +default. This keeps AVX-512 dynamic and safe while avoiding a register-pressure +regression on both tiny and small workloads. + +The current medium mixed-size memory soak (`16x16`, `3000x80`, `80x3000`, and +the 151-region `1920x1080` UI page; two cycles) established a post-warm-up +private-byte baseline of **347,013,120 bytes**. The next cycles were +**+303,104 bytes** and **+3,276,800 bytes**. This bounded allocator-capacity +movement is recorded as a Windows high-water observation rather than a general +leak proof; importantly it did not grow once per dynamic shape or per crop +batch. + +### 2026-08-11: GPU residual-vector and non-ReLU batch fusion follow-up + +The residual pointwise shader now vectorizes its common four-contiguous-spatial +lane case as well as the non-residual pointwise shader. It performs +`1x1 Conv + residual Add (+ ReLU)` in registers and writes one final NCHW +result, retaining a scalar tail only at plane boundaries and odd widths. The +graph loader also recognizes the strict dynamic `1x1 Conv -> equal-shape Add` +form without a following ReLU as `FusedPointwiseConvAdd`. This matters for +the medium recognizer: a CPU profile of `mixed.ppm` observed fused non-ReLU +shortcut nodes such as `Conv.9_add`, `Conv.20_add`, `Conv.50_add`, and +`Conv.31_add`, so they now avoid a materialized Conv result plus a separate +Add pass on both CPU and eligible hybrid paths. Initializer/broadcast Adds +remain excluded, preserving ONNX bias semantics. + +The rebuilt Vulkan smoke suite passed all binary, broadcast, affine, normal +pointwise, residual pointwise, and residual-ReLU numerical checks on AMD +Radeon 780M Graphics. Its latest complete-transfer measurements were +**21.0106 ms GPU vs 0.02642 ms CPU** for `N=4,C=24,M=40,plane=257` pointwise +Conv and **14.2844 ms GPU vs 0.03048 ms CPU** for residual+ReLU; hybrid +therefore rejected both exactly as designed. The separate tiny five-image +C++/ORT text gate passed **5/5**, and the six-page mixed-size batch smoke +produced identical nested results in **81.021 ms** versus **122.164 ms** +serial (**1.508x**). A short `mixed.ppm` end-to-end check measured **34.379 +ms CPU** versus **40.314 ms hybrid** (one warm-up, three runs), so current +deployment guidance remains CPU for this UMA GPU; these GPU additions are +correct, batched building blocks rather than an unsupported full-GPU claim. + +### 2026-08-11: Vulkan mapped-memory policy revalidation + +The persistent Vulkan buffers now explicitly score host-coherent memory types +for this synchronous hybrid runtime: `HOST_CACHED` coherent memory is selected +first, then host-visible device-local coherent memory, then a portable coherent +fallback. This is not merely a theoretical ordering. An A/B on the Radeon 780M +showed that preferring host-visible `DEVICE_LOCAL` for every mapped buffer made +the complete binary segment about **10.65 ms GPU vs 0.0195 ms CPU**, while the +cached mapped policy restored it to **0.137 ms GPU vs 0.015 ms CPU**. The +device-local mapping was therefore rejected; shader-side device locality does +not compensate for slower CPU copies in an H2D/dispatch/D2H hybrid segment. + +With the restored policy, the refreshed smoke suite passed every numerical +case. Its four-crop affine-Swish segment was **0.13832 ms GPU vs 0.29722 ms +CPU**, so hybrid selects Vulkan for that shape; the pointwise and residual +pointwise probes remained transfer-bound (**20.6638 vs 0.0269 ms**, and +**14.3158 vs 0.03158 ms**, respectively) and are correctly retained on CPU. +This is the required behavior for `hybrid`: prefer GPU only when the measured +full segment is no slower, while avoiding a silent fallback in `gpu_only`. + +Post-change correctness evidence includes small and medium C++/ONNX Runtime +text parity on `en.ppm` (**1/1** each) and a medium mixed-size memory soak over +`16x16`, `mixed`, and the `1920x1080` 151-region UI image. Its post-warm-up +private-byte baseline was **361,832,448** and the next cycle was +**-7,499,776 bytes** from that baseline, consistent with a bounded allocator +high-water rather than retained dynamic workspaces. A six-page tiny batch +regression still returned byte-identical nested results; the shared-host run +measured **126.196 ms serial / 108.076 ms batch (1.168x)**. Timing varies with +contention, so this documents correctness and a measured throughput win rather +than a portable promise. + +### 2026-08-11: batched GPU Conv+Swish fusion + +### 2026-08-12: tiled batched Vulkan pointwise convolution + +The batched Vulkan `1x1` convolution shader now has a workgroup-tiled path +for `C <= 1024`. One 256-thread workgroup owns four output channels and a +256-pixel spatial tile, cooperatively stages the four immutable `[C]` weight +rows in shared memory, then produces four contiguous FP32 values per lane. +This removes the former per-`vec4` weight streaming in the common NCHW +pointwise case. The same path covers Conv, Conv+ReLU, Conv+Swish, and the +equal-shaped residual variants; odd plane tails still use an exact scalar +write and wider channel counts retain the established generic shader path. + +This is a real GPU-kernel and batch-throughput improvement, not an invented +end-to-end GPU win. On the local AMD Radeon 780M, the verified four-crop +`N=4,C=24,M=40,plane=257` smoke measurement improved from the earlier +multi-millisecond pointwise dispatches to **0.16412 ms GPU** for Conv and +**0.15202 ms GPU** for Conv+Add+Swish. CPU SIMD still measured **0.02170 ms** +and **0.09334 ms**, respectively, so the complete H2D/dispatch/D2H admission +rule correctly retains CPU on this UMA host. The smoke suite validates all +normal, ReLU, Swish, residual, and non-vector-aligned outputs before timing. + +The rebuilt tiny four-page scheduler check (`en`, `line_en`, `mixed`, `zh`; +batch size 4, recognizer parallelism 1, page parallelism 2) remained output +identical after the shader change. This run measured **128.114 ms serial / +88.105 ms batch (1.454x)** on CPU and **125.542 ms / 77.657 ms (1.617x)** +in hybrid mode. These short shared-host samples are scheduler evidence, not a +replacement for the paired ONNX Runtime table above. `gpu_only` remains +explicitly unavailable until the complete PP-OCRv6 graph is device-resident. + +For a post-change whole-pipeline sanity A/B on `en.ppm` (16 CPU workers, +batch size 4, recognizer parallelism 1, three warm-ups and ten timed runs), +hybrid measured **34.387 / 72.977 / 216.534 ms** for tiny/small/medium. +The separately sampled CPU tiny run was **36.125 ms**; due shared-host noise +and partial-graph selection these are not substituted for the longer paired +CPU-versus-ORT results. The relevant GPU proof is the verified tiled primitive +and its conservative per-shape full-transfer admission, not an unsupported +claim that all three models now execute fully on the Radeon GPU. + +The Vulkan pointwise kernel now also supports the graph-fused PP-OCR pattern +`1x1 Conv -> Sigmoid -> Mul` as an exact FP32 `1x1 Conv + Swish` operation. +Four equal-width NCHW crops share one submission; learned `[M,C]` weights and +`[M]` bias remain compact and can be retained in the persistent parameter +buffers. This removes the CPU-side full-output Swish traversal when a shape is +admitted to Vulkan, without changing the portable AVX-512/AVX2/NEON fallback. + +The smoke test verifies the fused output at every element for a four-crop, +non-vector-aligned `N=4, C=24, M=40, plane=257` workload. On the local Radeon +780M its full synchronous H2D/dispatch/D2H measurement was **12.2472 ms GPU +versus 0.13918 ms CPU**, so `hybrid` correctly retains CPU SIMD for that shape. +This is nevertheless a material batch-capable GPU graph building block: a +device/shape is allowed to select it only after this complete measurement and +numerical validation; it is not represented as an end-to-end GPU OCR win on +the present UMA system. The expanded tiny C++/ONNX Runtime text gate passed +**5/5** (`en`, English line, Chinese line, mixed, Chinese page), and the +six-page batch regression preserved identical OCR results at **123.546 ms +serial / 86.991 ms batch (1.420x)** on this run. + +### 2026-08-11: shortcut Swish fusion and broader regression pass + +Small and medium recognizers contain an inverted-residual suffix +`BatchNorm -> Swish -> Add(shortcut)`. The loader now recognizes this after +the first fusion sweep and emits one `FusedBatchNormSwishAdd` node. Its CPU +kernel produces the affine, exact logistic Swish and equal-shaped residual Add +in one traversal, reusing the dying BatchNorm input allocation. This removes +the intermediate Swish feature map and the separate Add pass. It is protected +by `PPOCR_DISABLE_BN_SWISH_ADD_FUSION=1` for A/B work; a short medium +`mixed.ppm` CPU check (one warm-up / three runs) measured **242.378 ms** fused +versus **260.514 ms** unfused (**7.0% lower latency**), with expected shared +host variance. + +Vulkan now exposes the matching batched `channel-affine + Swish + Add` +primitive. Its smoke test validates every output of four `8192`-float NCHW +crops. On the Radeon 780M, complete transfer timing was **0.14988 ms GPU vs +0.14072 ms CPU**, so hybrid correctly chose CPU for that exact case. The graph +path has the same cached no-slower admission rule: it may use Vulkan only when +the full H2D/dispatch/D2H measurement and FP32 validation win; otherwise it +uses the CPU fused path and does not add GPU overhead. + +Current post-change evidence: tiny C++/ORT text parity remained **5/5** over +English, Chinese and mixed samples; small and medium each passed an independent +ORT text check on `en.ppm` (**1/1** each). A six-page varied-content tiny batch +regression remained result-identical at **126.926 ms serial / 96.686 ms batch +(1.313x)**. A medium memory soak spanning `16x16`, mixed text, and a dense +`1920x1080` page finished one cycle **7,614,464 bytes below** its +376,975,360-byte post-warm-up baseline, consistent with bounded workspace reuse. + +### 2026-08-12: batched Vulkan HardSwish coverage + +The graph-fused detector pattern `1x1 Conv -> HardSigmoid -> Mul` now reaches +the Vulkan pointwise kernel as one exact `Conv+HardSwish` dispatch. The shader +receives the ONNX `alpha` and `beta` as raw FP32 push constants and writes +`x * clamp(alpha*x + beta, 0, 1)` directly to the final NCHW output. It uses +the same four-crop Y-dimension batch mapping, shared-weight tile, odd-plane +tail handling, persistent parameter cache, and complete H2D/dispatch/D2H +admission policy as the other pointwise variants. CPU retains its +AVX-512/AVX2/NEON/scalar exact fallback. + +The post-change Radeon 780M smoke suite validated every value of an odd-plane +`N=4, C=24, M=40, plane=257` batch. The full synchronous admission sample was +**0.15912 ms GPU / 0.02794 ms CPU**, so this UMA host correctly keeps that +segment on CPU; no end-to-end GPU OCR speedup is claimed. A seven-image tiny +CPU-versus-hybrid output gate (`en`, mixed, CJK, tiny, wide, low-contrast, +blank) passed **7/7** with identical decoded output. With recognizer batch size +4, recognizer parallelism 1, and page parallelism 2, the seven-image hybrid +batch gate preserved output identity and measured **337.565 ms serial / +234.153 ms page-batch (1.442x)**. This is scheduler throughput evidence on +the local machine, not a general GPU performance promise. + +### 2026-08-12: three-size CPU/hybrid and memory revalidation + +The current build was retested after the Vulkan HardSwish integration with +the official tiny, small, and medium model pairs. The seven-image C++/ONNX +Runtime text gate passed **7/7 for every model** (English, mixed Latin, +CJK, `16x16`, `3000x80`, low-contrast, and blank). The broader tiny stress +corpus also passed **11/11**, including rotated text, dense blobs, and +`1920x1080`/`2560x1440` screenshots. + +On `en.ppm` (2 warm-ups, 10 timed runs, 16 CPU workers, recognizer batch 4, +one recognizer worker), the local CPU/hybrid recheck was: + +| Model | CPU mean | Hybrid mean | CPU / Hybrid decoded output | +|---|---:|---:|---| +| tiny | 35.164 ms | 34.684 ms | identical | +| small | 71.442 ms | 71.286 ms | identical | +| medium | 205.222 ms | 225.598 ms | identical | + +Hybrid is therefore not described as a universal win: each Vulkan segment is +still admitted independently only when its verified complete transfer, +dispatch, and readback time is no slower than the CPU SIMD equivalent. The +medium mixed-size memory soak (`16x16`, mixed text, dense `1920x1080`; two +cycles) used 367,849,472 private bytes after warm-up and ended at ++4,378,624 bytes, consistent with bounded allocator high-water behavior. + +### 2026-08-11: batched residual Conv+Swish GPU fusion + +The Vulkan batch kernel now also supports the full graph-proven recognizer +suffix `1x1 Conv -> Add(shortcut) -> Sigmoid -> Mul` as mode 9: +`1x1 Conv + residual Add + exact Swish`. Equal-width OCR crops share its Y +dispatch dimension; the learned `[M,C]` weights and `[M]` bias remain compact +and cacheable, and the shortcut is read once before the final device write. +The CPU fallback adds `PointwiseConvAddSwish`, keeping the Conv+shortcut in +the existing AVX-512/AVX2/NEON fused path and overwriting that single output +allocation with exact Swish. Set +`PPOCR_DISABLE_POINTWISE_ADD_SWISH_FUSION=1` to restore the unfused ONNX +sequence for an A/B comparison. + +The extended Vulkan smoke test validates every value of an odd-plane +four-crop `N=4,C=24,M=40,plane=257` batch. On the local Radeon 780M, its full +H2D/dispatch/D2H comparison measured **12.3933 ms GPU vs 0.09822 ms CPU**, +so hybrid correctly rejected it. The currently profiled small PP-OCRv6 export +does not emit this exact four-node suffix, so no end-to-end OCR speed claim is +made for the new matcher yet; it is retained as a verified batch-capable +building block for compatible PP-OCRv6 exports, not an unsupported GPU speed +claim on the present UMA host. + +### Tiny / small / medium comparison + +The same complete two-line OCR pipeline was also measured with the official +three PP-OCRv6 model sizes on this 16-thread AVX-512-capable host. Model load +is excluded from steady-state latency. The native and ONNX Runtime commands +were run separately with the same PPM input and matching dictionaries. The +following exact-Erf run is the current repeated baseline; `PPOCR_APPROX_GELU` +was unset for every native measurement. + +| Model | Native runs / warmup | Pure C++ mean | ORT mean | Native / ORT | Native FPS | ORT FPS | +|---|---:|---:|---:|---:|---:|---:| +| tiny | 20 / 5 | 33.322 ms | 120.106 ms | 0.277x | 30.010 | 8.326 | +| small | 20 / 5 | 83.639 ms | 184.190 ms | 0.454x | 11.956 | 5.429 | +| medium | 20 / 5 | 281.236 ms | 428.584 ms | 0.656x | 3.556 | 2.333 | + +This current default-exact run is a same-host comparison with matching model +files and image. It shows lower C++ latency for tiny, small, and medium +(72.3%, 54.6%, and 34.4% respectively). The commands were run as paired +engine measurements, but Windows scheduling still affects individual samples; +the complete JSON output should be retained when refreshing capacity numbers. + +The earlier approximate-GELU deployment experiment is retained below as a +separate, opt-in result rather than being conflated with default ONNX-equivalent +execution: + +| Model | Native runs / warmup | Pure C++ mean | ORT mean | Native / ORT | Native FPS | ORT FPS | +|---|---:|---:|---:|---:|---:|---:| +| tiny | 10 / 3 | 34.125 ms | 137.535 ms | 0.248x | 29.304 | 7.271 | +| small | 8 / 3 | 95.049 ms | 226.928 ms | 0.419x | 10.521 | 4.407 | +| medium | 8 / 3 | 257.848 ms | 457.041 ms | 0.564x | 3.878 | 2.188 | + +All values are from the same 2026-08-11 host and PPM input. The native run +used the persistent 16-worker executor; ONNX Runtime used +`CPUExecutionProvider` with the matching 16-thread budget. The refreshed +measurements show lower mean latency for all three model sizes on this host. +The table below uses the validated optional approximate-GELU deployment setting; +the default exact-Erf paired comparison is documented above. +The opt-in approximation passed the strict 7-image text corpus and the 11-image +size/diversity stress corpus; retain the exact default for applications that +require strict numerical ONNX equivalence. +The specialized stride-2 3x3 gather path remains material for medium: +disabling it measured 2646.179 ms versus 1923.504 ms when enabled with one +requested worker. These are local measurements, not a portable performance +guarantee. + +All three model pairs produce the expected two recognized lines in the native +smoke test. The strict 7-image text-parity and 11-image size/diversity stress +gates below use tiny because their known-text expectations correspond to its +dictionary; they exercise input dimensions from 16x16 to 2560x1440. +The latest default-exact verification also forced the dynamic AVX2 fallback +with `PPOCR_DISABLE_AVX512=1`: tiny/small/medium completed at 43.170/113.518/ +408.928 ms in a short 8-run sweep. This confirms that AVX-512 remains a +runtime-selected acceleration, not a binary deployment requirement; ARM/NEON +and scalar paths retain the same portable graph implementation. + +### Batched constant-weight MatMul fusion + +Recognizer attention projections commonly have a batched activation and one +rank-2 immutable weight tensor. The executor now flattens those independent +batch dimensions into one tall GEMM call, avoiding repeated per-batch GEMM +dispatch and allowing the SIMD/NEON GEMM to use its normal row scheduling over +the whole recognition batch. No weights are repacked or duplicated, and every +output row keeps its original increasing-`K` FP32 accumulation order. This is +enabled by default on x86/AVX-512, x86/AVX2, ARM/NEON, and scalar builds; +`PPOCR_DISABLE_MATMUL_BATCH_FOLD=1` provides an A/B fallback. + +On the local 16-worker AVX-512 host, exact-GELU `mixed.ppm` measurements with +three recognized crops, batch size four, recognizer parallelism one, three +warmups and fifteen timed runs showed the direct batch benefit for small: +**137.925 ms mean** with the fold versus **195.572 ms** with the fallback +(29.5% lower latency). A separate default scheduler check (batch four, +parallelism fourteen, 3 warmups / 12 runs) measured **41.663 ms tiny**, +**93.915 ms small**, and **340.519 ms medium** on the same input. These +samples are host-specific and the medium workload remains dominated by +convolution, but they confirm that all three model sizes retain the same +correct batched path. Exact ONNX Runtime text parity remained tiny **5/5**, +small **3/3**, and medium **3/3** after the change. +The same fallback path now fuses equal-shape `1x1 Conv -> Add` residual +projections with an AVX2 four-output register tile rather than materializing +the Conv result before a separate Add. A fresh forced-AVX2 3-warmup/10-run +sanity sweep measured tiny/small/medium at 42.446/122.677/434.793 ms on the +shared host; these are coverage and stability samples rather than a paired +ORT comparison. The strict seven-image text gate passed 7/7 with AVX-512 +disabled. ARM/NEON has matching four-output fused residual code; it is selected +only when the target compiler exposes NEON, otherwise scalar remains valid. +For AVX-512, large 1x1 projections now use an eight-output register tile +(with four-output/tail handling retained for smaller shapes). It reuses each +loaded input vector across eight output channels and preserves each output +channel's reduction order. The exact-GELU text gate passed 7/7 and the +11-image size/diversity gate passed after this change; the default exact +three-model table above is the associated repeated benchmark. +A 30-run A/B on the same 16-worker host selected this default for the larger +models: small measured 106.047 ms with the eight-output tile versus 109.533 ms +with `PPOCR_DISABLE_AVX512_POINTWISE8=1`; medium measured 301.179 ms versus +313.123 ms. Individual Windows samples remain scheduling-sensitive, but both +the median and mean favoured the eight-output implementation in that repeated +comparison. +The same eight-output technique is implemented for the already fused +`1x1 Conv+ReLU` path, including its exact scalar tail and runtime ISA guards. +It passes the strict text corpus when enabled, but repeated small/medium +end-to-end A/B samples were mixed (and the 30-run medium sample favoured the +default four-output path: 257.914 ms versus 268.169 ms). It is therefore kept +behind `PPOCR_ENABLE_AVX512_POINTWISE_RELU8=1`, rather than silently trading +stable default latency for a workload-specific result. + +### Post-fusion comparison refresh + +The latest post-fusion same-host refresh (exact Erf-GELU, 16 requested workers, +5 warmups and 20 measured runs per engine) is recorded below. It includes the +new equal-shape `1x1 Conv -> Add` fusion; operator profiling confirmed fused +residual projections in the medium graph (for example `Conv.9_add`, +`Conv.12_add`, `Conv.20_add`, `Conv.50_add`, and `Conv.53_add`). As with the +earlier table, these are sequential paired measurements on a shared Windows +machine, so they document the current build rather than a portable guarantee. + +| Model | Pure C++ mean | ORT mean | C++ / ORT | Pure C++ FPS | ORT FPS | +|---|---:|---:|---:|---:|---:| +| tiny | 43.072 ms | 182.025 ms | 0.237x | 23.217 | 5.494 | +| small | 109.535 ms | 244.420 ms | 0.448x | 9.130 | 4.091 | +| medium | 359.697 ms | 642.622 ms | 0.560x | 2.780 | 1.556 | + +This refresh measured native latency lower by 76.3%, 55.2%, and 44.0% for +tiny, small, and medium respectively. The observed C++ ranges were +40.202--48.375 ms, 99.140--127.691 ms, and 284.395--396.259 ms; ORT also +showed large host-scheduling variance, especially medium (427.880--1285.338 +ms). Keep the original repeated table above for historical comparison and +rerun the paired procedure on the deployment CPU before capacity planning. + +The subsequent gate-fusion validation found 13/13, 13/13, and 5/5 fused +HardSigmoid gates in tiny, small, and medium profile runs respectively. Default +and forced-AVX2 strict text parity both passed 7/7, while the 11-image stress +set still passed 11/11. A short shared-host 3-warmup/10-run sanity sweep was +43.159 ms (tiny), 100.075 ms (small), and 416.331 ms (medium); the wide medium +p95 range reflects host scheduling, so these values are deliberately not +presented as a new ONNX Runtime comparison. + +The executor now additionally treats a last-use standalone `HardSigmoid` as +an in-place operation. This applies the same exact AVX-512/AVX2/NEON SIMD gate +without allocating a second activation tensor; it is especially relevant to +dynamic image sizes where keeping the graph frontier small lowers transient +memory. The current strict text and 11-image stress checks passed after this +lifetime optimization. +The detector reconstruction head now folds its terminal `ConvTranspose(2x2, +stride 2) -> Add([1,C,1,1])` pairs into the transposed-convolution bias during +model load. This removes both final feature-map Add traversals for tiny, small, +and medium (confirmed as `ConvTranspose.0_bias` and `ConvTranspose.2_bias` in +the medium operator profile) while retaining exact output and all ISA paths. +The strict seven-image comparison and 11-image dimension/diversity stress +suite remained fully passing after the change. + +The recognizer's direct `Conv -> Add([1,C,1,1]) -> ReLU` exports are now folded +at load time into the existing Conv+ReLU kernels. This adds the previously +missing no-Identity form of channel-bias folding, so small/medium stem +projections avoid a broadcast Add pass and its transient result. The same +matcher also recognizes canonical `Conv -> HardSigmoid -> Mul` gates and maps +them to the existing exact AVX-512/AVX2/NEON HardSwish kernel when encountered. +The default and forced-AVX2 tiny text-parity checks both passed 5/5 images, and +the 11-image 16x16-to-2560x1440 stress suite passed 11/11 after the change. + +### Current optimization validation and comparison refresh + +The current build adds the post-Conv Swish graph fusion described above. The +official medium model profiled here does not contain a matching +`Conv -> Sigmoid -> Mul` sequence after affine folding, so this generic fusion +does not contribute to the following current-model timing. The strict tiny +text-parity suite completed 5/5 images against ONNX Runtime after the change. +The benchmark below was then run on the same shared Windows host with +`PPOCR_BENCH_THREADS=16`, AVX-512 enabled dynamically, exact-Erf GELU, five +warmups and 20 measured iterations. It is recorded here as a reproducible +current-build comparison, not a portable capacity guarantee. + +| Model | Pure C++ mean | ORT mean | C++ / ORT | Pure C++ FPS | ORT FPS | +|---|---:|---:|---:|---:|---:| +| tiny | 40.159 ms | 140.930 ms | 0.285x | 24.901 | 7.096 | +| small | 95.946 ms | 234.128 ms | 0.410x | 10.422 | 4.271 | +| medium | 342.556 ms | 599.235 ms | 0.572x | 2.919 | 1.669 | + +For this run, native C++ latency was 71.5%, 59.0%, and 42.8% lower than ONNX +Runtime CPUExecutionProvider for tiny, small, and medium. Native throughput +was correspondingly 251.0%, 144.0%, and 74.9% higher. The native/ORT +median/p95 pairs were 39.217/44.732 vs. 142.425/199.114 ms (tiny), +94.667/103.429 vs. 234.956/276.820 ms (small), and 316.130/451.931 vs. +576.425/767.443 ms (medium). The shared Windows host is scheduling-sensitive, +so retain the ranges and rerun this paired procedure on a deployment CPU before +capacity planning. The existing tiny/small/medium repeated exact table remains +the longer-run model-size baseline. +### Dense-text stress result + +The small-image result above is not representative of a screen with hundreds +of detected text regions. The native path groups equally sized crops into +bounded batches and schedules up to fourteen independent batches concurrently; +each batch retains its output order and uses an isolated execution workspace. +When multiple batches concurrently reach a CPU-parallel operator, one uses the +persistent worker set while contenders execute their independent channel split +locally. This prevents shared-pool serialization and nested-worker contention. +For the PP-OCR recognizer's terminal CTC head it also reduces logits directly +to argmax plus selected-character probabilities, avoiding an otherwise unused +`[batch,time,6906]` Softmax tensor. +Last-use elementwise activations (GELU, BatchNorm+GELU, ReLU, h-swish and +scale/shift) are updated in-place, eliminating transient activation copies. The +BatchNorm+GELU path now evaluates the exact-Erf GELU in the same pass as its +affine transform, removing a further full activation read/write in the default +exact mode. In the explicitly enabled approximate-GELU deployment mode, the +same affine result routes through AVX-512/AVX2 scale-shift plus vector GELU; +the corpus gates above validate that optional path. +Recognizer `Conv -> BatchNorm` inference pairs are folded into immutable +convolution weights and biases during model loading, removing the BatchNorm +activation pass without changing the deployed C++ runtime dependencies. +The detector FPN `2x2`, stride-2 transposed-convolution blocks have dedicated +AVX2 and AVX-512 implementations selected through the existing runtime ISA +dispatch. They vectorize independent input pixels while keeping the same +output/input-channel accumulation order; scalar and ARM builds retain the +portable implementation. In a direct dense-page operator profile, the two +blocks totalled 3.135 ms with AVX versus 3.597 ms scalar (about 12.8% for +those kernels). +The neighbouring detector reconstruction `2x2` valid convolutions now also +have dedicated AVX-512 and AVX2 kernels. They stream the four contiguous input +rows required by each output vector and avoid generic padding/interior checks; +ARM and scalar builds retain the portable kernel. On the current host this +changed the complete two-line small model from 110.364 ms to 98.112 ms and the +medium model from 352.690 ms to 338.791 ms in the same short-run configuration +(about 11.1% and 3.9% respectively), while dense tiny recognition measured +243.949 ms for 123 boxes. +The larger stride-one `3x3` detector layers use an AVX-512 four-output-channel +kernel as well. Each input vector is loaded once and accumulated into four +independent channel outputs, retaining the original channel/kernel accumulation +order. On the medium profile this reduced `Conv.121` from 26.809 ms to 5.910 ms +and `Conv.3` from 20.759 ms to 12.379 ms; the complete short-run medium OCR +measurement improved from 338.791 ms to 291.049 ms. AVX2, NEON, and scalar +paths remain available through runtime ISA dispatch. +The same four-output `3x3` algorithm is now implemented for AVX2 as well. An +explicit `PPOCR_DISABLE_AVX512=1` run exercised that fallback on the present +machine: medium completed in 404.166 ms and the strict tiny text corpus passed +7/7, confirming that advanced instructions remain dynamically optional rather +than a deployment requirement. ARM/NEON retains its portable vector path. +The scheduler now divides these fused `3x3` layers by four-channel groups, +instead of splitting a group between CPU workers. This preserves input-vector +reuse even for channel-parallel medium layers and safely sends only an incomplete +last group to the scalar tail. The resulting AVX-512 medium run measured +279.329 ms (3.580 FPS); strict text and the 11-image dimension/diversity corpus +both remained fully passing. +The same AVX-512 four-output strategy now covers the medium detector's square +stride-one `5x5` and `7x7` context layers. It cut the profiled `Conv.111` +7x7 from 8.472 ms to 3.898 ms and `Conv.114` 5x5 from 3.973 ms to 1.938 ms; +the complete medium result improved from 279.329 ms to 257.848 ms (3.878 FPS). +Unsupported ISAs and non-square/asymmetric kernels continue through the +existing AVX2/NEON/scalar paths. +Depthwise dispatch now routes square stride-one `7x7` and `9x9` kernels to the +existing AVX-512/AVX2 vector kernel too. This covers medium `Conv.64` (256 +channels, 9x9): its local operator profile fell from 8.080 ms to 4.845 ms. +The native benchmark's current medium distribution remains sensitive to shared +host scheduling, so the paired end-to-end table is retained as the comparable +model-size result rather than replacing it with an unpaired one-off sample. +For `1x1 Conv -> ReLU` sequences, the AVX-512 path now applies the clamp before +storing each register-tiled output vector. This removes the separate activation +read/write for the fused detector projections while leaving AVX2, NEON, and +scalar execution on the existing safe Conv-then-ReLU path. The strict text and +11-image dimension/diversity gates passed after the change. On this shared +benchmark host the short medium samples remained scheduler-noisy, so no new +end-to-end speed claim is made without a paired repeated run. +The default exact-Erf GELU path is also parallelized across independent NCHW +planes through the persistent executor. BatchNorm+GELU now precomputes its +per-channel affine coefficients once and submits plane-local exact evaluation +without allocating another activation. On medium profiling this changed the +13 fused GELU calls from 26.743 ms to 7.297 ms while retaining default ONNX +Erf semantics; the strict text and 11-image stress gates passed with +`PPOCR_APPROX_GELU` unset. The optional approximate mode remains available for +deployment-specific validation, not as a correctness requirement. +The recognizer terminal CTC Top-1 reduction now parallelizes only across +independent batch sequences. Each sequence retains its own blank/repeated-token +state, while dense-page batches can distribute vocabulary scans and the selected +character confidence softmax over the persistent worker set. Exact decoded-text +and the 11-image dimension/diversity gates passed in default exact-GELU mode; +the shared-host dense benchmark remains variable, so its paired table remains +the authoritative capacity-planning reference. +CTC's 6,906-way per-step ArgMax also uses dynamically selected AVX-512 or AVX2 +vector reductions. It explicitly scans the non-vector-width tail before +locating the first winning class, preserving the scalar tie rule and ensuring +the final vocabulary entries (including the space class) remain observable. +Both default AVX-512 and forced `PPOCR_DISABLE_AVX512=1` AVX2 runs passed the +strict 7-image text corpus; the current exact-GELU dense 123-box run measured +345.415 ms (median 343.977 ms, p95 359.279 ms), subject to the documented +shared-host scheduling variation. +AVX-512 four-output fusion now also covers stride-one asymmetric `1x3/1x5/1x7` +and `3x1/5x1/7x1` detector convolutions. It vectorizes the contiguous spatial +axis, preserves scalar border accumulation, and assigns four-channel groups to +workers so input loads are reused. Medium `Conv.112` (7x1) fell from a recent +3.363 ms profile to 1.211 ms. Default exact-GELU strict-text and 11-image +dimension/diversity gates remained passing; standalone medium timing is still +reported with the documented shared-host variance rather than as a new paired +ORT claim. +The DB connected-component postprocessor represents threshold and visited state +in one byte per probability-map pixel (`0` background, `1` pending, `2` visited), +instead of two full byte maps. This halves that postprocessor workspace while +leaving thresholding, traversal order, scores, boxes, and reading order unchanged. +The detector terminal `Sigmoid` is also executed in-place whenever its input +has no remaining consumers. It reuses the final DB-logit allocation as the +probability map, eliminating a peak activation allocation and copy while +preserving the exact scalar sigmoid expression. +Detector FPN nearest-neighbour integer upscales are implemented as direct +NCHW row replication, and recognizer inverse-Transpose pairs plus Conv channel +bias broadcasts are removed at model load. These changes eliminate dynamic +activation copies without relaxing the exact-GELU accuracy path. +The executor also prunes original constants made unreachable by load-time +Conv/BatchNorm folding. This applies to tiny, small, and medium without +changing runtime graph inputs. A fresh two-cycle mixed-size medium soak +(16x16, 3000x80, noisy scene and 1920x1080 UI page) used a 146.94 MiB +post-warmup baseline; the cycles were 147.21 and 148.18 MiB (+0.27 and ++1.24 MiB). The variation is Windows heap retention rather than monotonic +per-shape growth; longer soak runs should be used for release qualification. +The same mixed-size medium sequence in default exact-GELU mode used a 147.68 +MiB post-warmup baseline; two cycles ended at 146.48 MiB and 152.16 MiB +(-1.20 / +4.48 MiB). This is bounded allocator retention rather than a +per-shape activation cache; use longer production soak runs for qualification. +A fresh four-cycle medium run after the pointwise-tile update used a 149.641 +MiB post-warmup baseline and ended at 146.504 MiB (-3.137 MiB); its largest +cycle was only 2.022 MiB above baseline. The mixed sequence covered 16x16, +3000x80, low-contrast, and 1920x1080 dense-page inputs, again showing bounded +Windows allocator retention rather than persistent dynamic-shape growth. +The AVX2/AVX-512 direct-convolution path now also covers stride-1 7x7 and +asymmetric 3/5/7x1 or 1x3/5/7 detector kernels, while preserving the same +output/input-channel/kernel accumulation order; ARM and scalar paths retain +the portable implementation. +The dominant NCHW `1x1` convolution kernel also now computes four output +channels per shared SIMD input load (AVX-512, AVX2, and NEON implementations), +reducing hot-path input bandwidth while preserving each channel's accumulation +order. +The detector DB-head `2x2`, stride-1 `SAME_UPPER` max pool is likewise mapped +to a boundary-safe AVX-512/AVX2/NEON kernel, removing generic window and bounds +reconstruction from every output pixel. +The following repeatable stress measurement records the present result on +`build/ui_dense_1920x1080.ppm` (about 123--124 text regions): + +| Engine | Warmup | Measured runs | Mean latency | Throughput | +|---|---:|---:|---:|---:| +| Pure C++ PP-OCRv6 | 4 | 10 | 233.805 ms | 4.277 FPS | +| ONNX Runtime 1.28 CPUExecutionProvider | 4 | 10 | 929.357 ms | 1.076 FPS | + +The table uses one paired `compare.ps1` run with the persistent executor and +validated approximate-GELU setting. C++ is **74.8% lower latency** (0.252x) and +**297.5% higher throughput** in this specific run. It replaces the previous +serial-recognition baseline of 2680.808 ms, a **11.47x** native speedup. +A repeated parameter +sweep after the copy-elimination changes selected the current default of +`rec_batch_size = 4` and +`rec_parallelism = 14` for this 16-logical-CPU host; applications can tune +these options for their deployment CPU. Short dense runs can vary +materially with CPU scheduling, so use the command below and more runs on the +deployment target before capacity planning: + +`Options::rec_batch_width_bucket` (or benchmark environment variable +`PPOCR_REC_WIDTH_BUCKET`) can additionally pack nearby natural crop widths +into one zero-right-padded batch; each crop keeps its own aspect-ratio resize. +The default remains `1`: a local 123-crop dense-page sweep did not demonstrate +a stable CPU benefit from padded work, so exact-width batching remains the +lower-memory default. Wider buckets are available for deployment-specific GPU +or batch-density tuning. + +```powershell +powershell -ExecutionPolicy Bypass -File .\bench\compare.ps1 ` + -Image .\build\ui_dense_1920x1080.ppm -Runs 10 -Warmup 4 -Threads 16 +``` + +The captured result is C++ 233.805 ms (median 232.980 ms, p95 244.485 ms) and +ONNX Runtime 929.357 ms (median 930.224 ms, p95 1098.989 ms). Keep repeated +paired measurement when refreshing the table, because dense-page latency can +vary with host scheduling. + +The run used four warmups, 10 measured runs, and matching 16-thread CPU budgets. +Use longer repeated measurements on the deployment CPU before capacity planning; +dense-page latency also depends strongly on the detected crop mix. + + +### Expanded stress corpus + +`bench/stress_regression.py` executes the native C++ pipeline over 11 deterministic +local stress images without adding a runtime dependency. It covers 16鑴?6 tiny text, +3000鑴?0 and 80鑴?000 strips, low contrast, rotation, blank input, dense synthetic +text, and 1920鑴?080 / 2560鑴?440 screenshots. The gate asserts bounded detection +counts, valid confidence/geometry, and high-confidence text anchors where exact +front-end parity is meaningful; rotated and density-only cases intentionally test +robustness rather than unstable line ordering. + +```powershell +& 'D:\workprj\aicoder\.tmp\ocr-models\.venv\Scripts\python.exe' ` + .\bench\stress_regression.py ` + --cpp .\build\ppocr_demo.exe ` + --det D:\workprj\aicoder\.tmp\ocr-models\ppocrv6_tiny_det.onnx ` + --rec D:\workprj\aicoder\.tmp\ocr-models\ppocrv6_tiny_rec.onnx ` + --dict D:\workprj\aicoder\.tmp\ocr-models\dict_ppocrv6_tiny.txt ` + --images D:\workprj\aicoder\corelib\ocr\testdata\stress +``` + +Latest local run: **11/11 passed** (box counts: 123, 0, 1, 1, 20, 1, 3, 6, 743, +34, 38). This broadens the existing strict 7-image text-parity gate; it does not +weaken it. + +### Recognition-regression corpus + +`bench/accuracy_compare.py` compares complete C++ OCR results against an ONNX +Runtime CPU reference. Its default gate checks detected-line count and decoded +text; confidence and geometry are retained in the JSON report but do not gate +the test because the two standalone frontends have small resize/crop rounding +differences. Pass `--strict-geometry` to also gate those fields. + +`bench/accuracy_expectations.json` supplies independently recorded expected +text for the deterministic corpus, so the same run also checks C++ results +against known text rather than only comparing two inference backends. + +The latest 7-image corpus passed **7/7 text-parity cases**. It includes clean +multi-line English, a single word, a 3000-pixel-wide receipt line, a +low-contrast/noisy scene, a blank image, and a 16x16 tiny-text case. The +samples are existing deterministic test assets from +`D:\workprj\aicoder\corelib\ocr\testdata`. + +An additional multilingual and extreme-shape sweep covers Chinese and mixed +language text, a 80x3000 vertical strip, rotated text, synthetic dense blobs, +and 1920x1080/2560x1440 screenshots. Chinese/mixed baseline samples retain +exact decoded-text parity. The pathological vertical/dense screenshot samples +remain diagnostic rather than release gates because detector/crop rounding can +alter weak low-confidence regions between the two independently implemented +frontends. `accuracy_compare.py` now forces UTF-8 report output so this corpus +can be run from a Windows GBK console without losing dictionary characters. + +```powershell +$images = @( + 'D:\workprj\aicoder\corelib\ocr\testdata\en.png', + 'D:\workprj\aicoder\corelib\ocr\testdata\line_en.png', + 'D:\workprj\aicoder\corelib\ocr\testdata\stress\single_word.png', + 'D:\workprj\aicoder\corelib\ocr\testdata\stress\wide_strip_3000x80.png', + 'D:\workprj\aicoder\corelib\ocr\testdata\stress\noisy_lowcontrast.png', + 'D:\workprj\aicoder\corelib\ocr\testdata\stress\blank_800x600.png', + 'D:\workprj\aicoder\corelib\ocr\testdata\stress\tiny_16x16.png' +) +& 'D:\workprj\aicoder\.tmp\ocr-models\.venv\Scripts\python.exe' ` + .\bench\accuracy_compare.py ` + --cpp .\build\ppocr_demo.exe ` + --python 'D:\workprj\aicoder\.tmp\ocr-models\.venv\Scripts\python.exe' ` + --det 'D:\workprj\aicoder\.tmp\ocr-models\ppocrv6_tiny_det.onnx' ` + --rec 'D:\workprj\aicoder\.tmp\ocr-models\ppocrv6_tiny_rec.onnx' ` + --dict 'D:\workprj\aicoder\.tmp\ocr-models\dict_ppocrv6_tiny.txt' ` + --expectations .\bench\accuracy_expectations.json ` + --images $images +``` + +Captured report: `build/accuracy_ground_truth_7_ctctop1_sparse.json` (7/7 +passed after batch/concurrent recognition and terminal-CTC reduction). + +### Dynamic-size memory soak + +`ppocr_mem_soak` keeps one C++ OCR instance alive while repeatedly alternating +tiny, wide-strip, noisy, and 1920x1080 UI images. It reports process-private +bytes after every complete mixed-size cycle. Intermediate tensors are released +after their final graph consumer, model weights remain immutable, and no +per-shape activation cache is retained. Detector results (including the large +probability map) are additionally scoped through DB post-processing and released +before concurrent recognition batches begin, so the allocator can reuse their +storage rather than combining detector and recognizer activation peaks. + +The same process-level workload can be run against ONNX Runtime with +`bench/ort_mem_soak.py`. On this Windows host, using 12 mixed-size cycles: + +| Engine | Baseline private bytes | Final private bytes | Final change | +|---|---:|---:|---:| +| Pure C++ PP-OCRv6 | 23.825 MiB | 24.633 MiB | +0.809 MiB | +| ONNX Runtime CPU | 145.371 MiB | 203.805 MiB | +58.434 MiB | + +The current C++ run ranged from 22.735 MiB to 27.703 MiB after the baseline; +its final working set was 0.809 MiB above the immediate post-load baseline, +without a monotonic per-cycle increase.

It +records every resolution and requires the final `64x64` sample to remain +within 20% of both the warmed baseline and the final ultra-tall recovery +sample, as well as within 20% of the earlier `3840x2160` sample. The report +includes `declined_after_largest`, so allocator capacity retention +cannot be confused with an actual post-large-image recovery observation: + +```powershell +& 'D:\workprj\aicoder\.tmp\ocr-models\.venv\Scripts\python.exe' ` + .\bench\memory_ladder_regression.py ` + --cpp .\build\ppocr_mem_soak.exe --det --rec ` + --dict --images .\build\memory_ladder --cycles 2 --backend cpu ` + --require-post-large-decline +``` + +`ppocr_mem_soak` loads, infers, and destroys one RGB image at a time and emits +one private-byte sample after every resolution. The final small-page sample +is therefore the direct recovery observation after the staged 4K and +extreme-aspect-ratio tail; compare it with the `ladder_3840x2160` and final +`ladder_recovery_256x4096` samples and the next cycle rather than treating +the process allocator's high-water capacity as a leak. Run the same command +with `PPOCR_BACKEND=hybrid` to include the persistent Vulkan buffers in the +process-level measurement. + +The current generator intentionally uses an ascending, aspect-ratio-diverse +16-sample sequence: `16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> +1280x720 -> 4096x256 -> 256x4096 -> 1920x1080 -> 2560x1440 -> 3000x1600 -> +3840x2160 -> 1920x1080 -> 4096x256 -> 256x4096 -> 64x64`. The final staged +recovery tail checks that memory remains bounded after both 4K area and +extreme-aspect-ratio images. In addition to private bytes, +the native JSON now includes Windows working-set bytes for each measured +sample. Private bytes remain the bounded-recovery gate; working set is +reported as complementary residency evidence because the Windows heap and +Vulkan driver may retain reusable committed capacity after the page and its +activations have been destroyed. + +The generator also includes native **5K** (`5120x2880`) and **8K** +(`7680x4320`) source pages. The 8K sample is followed immediately by a 4K +recovery sample, so use `--require-post-large-decline` to make both Windows +private bytes and working set decline at that exact transition a strict gate. +This catches source-image retention even though detector inference itself is +normally capped by `det_limit_side_len`. + +### 2026-08-14: current small-to-large image-memory check + +The checked-in generator was rerun against the current medium PP-OCRv6 CPU +build. It creates the deterministic 16-image sequence above, processes each +image with one long-lived OCR instance, and destroys the decoded RGB image +before sampling process memory. The result therefore measures retained +runtime/allocator capacity rather than intentionally retained source images. + +In the current one-cycle run, private memory was **147,017,728 B** at +`3840x2160`, then immediately declined to **146,296,832 B** at the following +`1920x1080` sample (**-720,896 B**, **-0.49%**). Working set also declined +from **150,679,552 B** to **150,085,632 B** (**-593,920 B**). After the +complete recovery tail, the final `64x64` sample was **147,124,224 B** private +and **151,035,904 B** working-set memory: below the pre-return peak +(**148,320,256 B** private / **152,371,200 B** working set), and only **2.21%** +above the warmed private baseline (**143,937,536 B**). The bounded-recovery +gate passed. Full per-resolution evidence is +`build/memory_ladder_medium_cpu_current_20260814.json`. + +Windows allocation is intentionally treated as a bounded-recovery result, not +as a requirement that every allocator page be decommitted immediately: the +explicit first-post-4K samples prove the observed downward transition, while +the final small-image sample guards the durable footprint after the whole +large-image sequence. + +### 2026-08-13: current ascending-resolution memory measurement + +With the current default recognizer batch size of 1, CPU backend, 16 kernel +workers, and approximate GELU, medium PP-OCRv6 passed a fresh one-cycle +ascending-resolution check. The run covers every generated image from +`16x16` through `3840x2160` (including `4096x256` and `256x4096`), then the +staged recovery tail and a final `64x64`. Private bytes were **147,234,816 B** +after `3840x2160` and **147,144,704 B** after the final `64x64`, a decline of +**90,112 B (0.06%)**. Working set likewise declined from **151,109,632 B** to +**150,913,024 B** (**196,608 B**). The final private-byte value was **0.008%** +above the fully warmed **147,132,416 B** baseline and 2.38% below the +pre-return peak, so every 20% bounded-recovery gate passed. The complete +per-resolution record is +`build/memory_ladder_medium_cpu_ascending_recheck_20260813.json`; values are +host-specific allocator observations, rather than a promise of immediate heap +decommit on every operating system. + +### 2026-08-13: per-resolution memory-record validation + +The ladder checker now preserves the private-byte and working-set sample for +**every** image resolution in its JSON report, together with the cycle peak +and a direct post-`2560x1440` recovery flag. This makes the check suitable for +both leak detection and deployment profiling: a final small-page allocation is +not mistaken for the large-page allocation just because a heap or driver keeps +reusable capacity committed. + +On the current AVX-512 Windows host, medium PP-OCRv6 with 16 kernel workers +and opt-in approximate GELU passed two fresh CPU ladder cycles. The warmed +private baseline was **146,632,704 bytes**. After `2560x1440`, the final +`64x64` sample was **148,533,248 bytes** in cycle 1 (+1.30% baseline, +2.00% +from the largest-page sample) and **143,220,736 bytes** in cycle 2 (-2.33% +baseline, -1.23% from the largest-page sample). Thus direct private-byte +recovery occurred in the second cycle but not the first: Windows heap reuse +can retain or move committed capacity between samples. Both final samples +remained within the 20% bounded-recovery limit, which is the pass/fail gate; +the JSON deliberately retains the explicit per-cycle recovery flag instead of +claiming unconditional decommit after a large image. + +The same two-cycle Hybrid Vulkan run also passed. Its warmed private baseline +was **394,969,088 bytes** and each final `64x64` sample was **396,017,664 +bytes** (+0.265%). The final private bytes equalled the immediately preceding +`2560x1440` sample in both cycles, while the working set was essentially flat +(+12,288 bytes in cycle 1 and +8,192 bytes in cycle 2). This is persistent +Vulkan/Windows allocator capacity rather than evidence that an image or its +activations remain live. These are machine-specific process measurements; +the exact per-resolution values are retained in +`build/memory_ladder_medium_{cpu,hybrid}_20260813.json` when the commands are +run locally. + +On 2026-08-12, the current medium model passed this expanded two-cycle gate. +CPU warmed at **148,127,744 B** and returned to **147,148,800 B** and +**147,152,896 B** (both **-0.66%** of baseline); the final small-page samples +were 2.33% and 1.70% above their immediately preceding largest-page samples. +Hybrid Vulkan warmed at **393,490,432 B** and returned at **395,317,248 B** +(+0.46%) and **395,341,824 B** (+0.47%). All private-byte deltas passed the +20% gate. The resident working-set observations are also captured in the +checker output rather than being inferred from private bytes; on this shared +Windows host they remained within the allocator/driver's warmed range, not a +claim that either heap must promptly decommit pages. + +On 2026-08-12, the tiny model with 16 CPU workers was run through this exact +seven-image ladder. CPU-only warmed to **9,400,320 bytes**; after the largest +`2560x1440` page its next small-page sample was **9,465,856 bytes** +(**+65,536 bytes**, 0.7% of baseline). Hybrid warmed to **116,305,920 bytes** +and the corresponding post-large small-page sample was **115,802,112 bytes** +(**-503,808 bytes**). These per-image values show recovery after the largest +input for both modes. They are Windows private-byte observations on this +host, not a cross-platform leak proof or a fixed memory guarantee. + +The same seven-page gate was rerun after the depthwise-pointwise-GELU graph +fusion with the **medium** PP-OCRv6 model (two measured cycles, default bounded +CPU scheduler). Both modes passed the 20% bounded-recovery limits: + +| Backend | Warmed baseline | Final `64x64`, cycle 1 | Final `64x64`, cycle 2 | Result after `2560x1440` | +|---|---:|---:|---:|---| +| CPU | 136.351 MiB | 140.019 MiB (+2.69%) | 140.008 MiB (+2.68%) | Allocator private bytes did not immediately decline, but remained stable and 2.24閳?.29% above the largest-page sample. | +| Hybrid Vulkan | 360.574 MiB | 361.582 MiB (+0.28%) | 361.582 MiB (+0.28%) | Equal to the immediately preceding largest-page sample in both cycles. | + +The CPU observation is expected on Windows: completed image and activation +objects have been destroyed, while the process allocator may retain reusable +blocks. Consequently the test reports both `declined_after_largest` and the +bounded deltas instead of treating an unchanged private-byte high-water mark +as proof of a live-image or tensor leak. The Hybrid samples include its +persistent Vulkan allocations. + +The same CPU-only one-cycle ladder was also run for the other two PP-OCRv6 +sizes: small warmed to **37,662,720 bytes** and returned at +**38,973,440 bytes** after its largest page (**+1,310,720 bytes**); medium +warmed to **147,435,520 bytes** and returned at **148,439,040 bytes** +(**+1,003,520 bytes**). In both cases the return sample remained within 3.5% +and 0.7% of their post-warm-up baselines respectively, with no retained RGB +source images between calls. + +The reusable checker was then run for two full ladders after the per-image +sampler change. All three CPU models passed the 20% bounded-recovery gate: +tiny returned within **+1.14%**, small within **+10.09%**, and medium within +**+2.46%** of their warmed baselines; each final `64x64` sample was also at or +below the pre-large `1920x1080` sample except medium's first cycle (**+0.81%**). +Tiny hybrid also passed, returning within **+0.08%** of baseline, including +the persistent Vulkan allocation. These figures are deliberately a bounded +allocator-reuse test, not an assertion that Windows must immediately release +committed heap pages to the OS. + +The current checker also makes the immediate recovery result explicit. On a +fresh two-cycle tiny run with the default 12 workers, CPU warmed to +**10,047,488 bytes** and returned at **9,379,840** then **9,441,280 bytes**; +both cycles reported `declined_after_largest=true` (2.97% and 9.64% below the +preceding `2560x1440` samples). Hybrid warmed to **135,745,536 bytes** and +returned at **135,098,368** then **135,102,464 bytes**, both below its warmed +baseline but **not** immediately below the preceding largest-image samples +(`declined_after_largest=false`, +1.24% and +0.63%). This distinction is +intentional: the test reports the actual post-large behavior and separately +enforces bounded recovery, rather than incorrectly claiming immediate heap +release for persistent Vulkan/Windows allocator capacity. + +### 2026-08-12: current ascending-resolution memory check + +The deterministic seven-image ladder was regenerated and rerun on the current +binary: `64x64 -> 320x240 -> 640x480 -> 1280x720 -> 1920x1080 -> 2560x1440 +-> 64x64`. Each sample performs `load -> Recognize -> destroy -> +PrivateBytes`, so the reported process-private bytes include runtime working +memory but do not retain the source RGB page between samples. The bounded +20% return gate passed in every run below. + +| Model / backend | Warmed baseline | Cycle 1 final 64x64 | Cycle 2 final 64x64 | Post-largest result | +|---|---:|---:|---:|---| +| tiny / CPU | 9,367,552 B | 9,412,608 B (+0.48%) | 9,424,896 B (+0.61%) | Fell below the preceding 2560x1440 sample in both cycles (11.17%, 1.75%). | +| medium / CPU | 148,254,720 B | 146,284,544 B (-1.33%) | 147,300,352 B (-0.64%) | Bounded return; final sample was 1.08% / 2.65% above the immediately preceding large sample. | +| tiny / hybrid Vulkan | 115,851,264 B | 99,143,680 B (-14.42%) | 98,140,160 B (-15.29%) | Bounded return; final sample was 0.004% / 0.017% above the immediately preceding large sample. | + +`declined_after_largest` is therefore true for the CPU tiny run and false for +the medium CPU and hybrid runs. That false value is an observation, not a +leak verdict: Windows heap and persistent Vulkan allocations may retain or +rearrange reusable capacity. The two complementary checks閳ユ敄he final-small +sample versus its post-warm-up baseline and the stated largest-page +comparison閳ユ攷ake the memory behavior auditable without claiming that a process +must immediately return committed pages to the OS. + +After the subsequent depthwise-pointwise-GELU fusion, the medium ladder was +rerun with two cycles. CPU warmed at **142,974,976 B**; its final `64x64` +samples were **146,821,120 B** (+2.69%) and **146,808,832 B** (+2.68%). +They were 2.29% and 2.24% above the respective `2560x1440` samples, so +`declined_after_largest=false`, yet both are stable and well within the 20% +bounded-return gate. Hybrid warmed at **378,089,472 B** and returned at +**379,146,240 B** in both cycles (+0.28%); each final small image equalled its +preceding largest-image sample (`declined_after_largest=true`). Thus the +test continues to distinguish released OCR image/tensor lifetimes from normal +Windows heap or persistent Vulkan capacity retention. + +### 2026-08-12: admitted depthwise-to-pointwise Vulkan segment + +The graph loader now recognizes an exact `depthwise Conv(bias) -> 1x1 +pointwise Conv(bias)` pair and emits `FusedDepthwisePointwiseConv`. Its CPU +path remains the same two SIMD kernels, while hybrid can submit the existing +Vulkan chain in one command buffer: the depthwise result stays in a device +storage buffer and only the chain boundaries transfer. Admission is cached +per full NCHW geometry and accepts GPU only after a repeated H2D + dispatch + +fence + D2H comparison and elementwise CPU-result validation show that the +complete segment is no slower. Consequently this reduces CPU occupancy when +the Radeon/driver wins without forcing a transfer-bound GPU route. + +The feature covers the detector MobileNet backbone pairs in all three model +sizes. AVX-512 kernel smoke and the four diverse decoded-text comparisons +for tiny, small and medium all passed (**12/12**). The current Radeon 780M +primitive probe measures a representative depthwise-to-pointwise batch at +**0.76714 ms GPU vs 0.20474 ms CPU**, so this particular UMA shape is +correctly rejected; it is evidence that the new graph route retains the +no-slower policy rather than a claim of blanket GPU acceleration. A current +20-run CPU-only `en.ppm` snapshot (16 kernel workers, approximate GELU) +measured tiny **27.954 ms**, small **60.455 ms**, and medium **195.588 ms**. +`gpu_only` still fails explicitly because the complete PP-OCRv6 graph, +post-processing and CTC decode are not yet device resident; it never silently +falls back to CPU. + +### 2026-08-12: depthwise-to-pointwise CPU graph fusion + +The same strict MobileNet `depthwise Conv(bias) -> 1x1 pointwise Conv(bias)` +pattern now executes as one graph node on CPU too. It removes the executor's +hash-map entry, node dispatch and intermediate tensor lifetime from the graph; +the internal temporary remains only for the two exact SIMD kernels. This is +an intentional graph/lifetime fusion, not a mathematical approximation. Set +`PPOCR_DISABLE_DEPTHWISE_POINTWISE_FUSION=1` for an A/B fallback. + +On the current 16-worker AVX-512 host, three warm-ups and fifteen `en.ppm` +runs showed the fused path at **26.784 / 56.596 / 174.962 ms** for tiny, +small and medium, respectively, compared with **27.121 / 58.209 / 228.572 +ms** with the graph fusion disabled. The medium result is host-scheduling +sensitive, so the reproducible conclusion is the consistent no-regression +and gains for tiny/small, while deployment owners should rerun the medium A/B +on their target CPU. A separate 20-run medium A/B measured **213.711 ms** +fused versus **222.719 ms** disabled. The exact decoded-text gate passed +**12/12** across tiny/small/medium and four diverse inputs. A two-cycle +medium resolution ladder also passed the bounded memory-recovery gate: +147,255,296-byte warmed baseline; final small-page samples were -0.68% and +-0.08% from baseline. As elsewhere, the final samples did not immediately +fall below the preceding maximum-size sample, which is normal reusable +Windows allocator capacity rather than a leak assertion. + +### 2026-08-12: depthwise-pointwise-GELU liveness fusion + +The loader now extends that exact single-use pattern through an immediately +following fused GELU as `FusedDepthwisePointwiseConvGelu`. The pointwise +output is activated in place, rather than re-entering the generic graph loop +to rename and transform it. It preserves FP32 operation order (the same +existing GELU kernel runs after the two convolutions) and keeps the Vulkan +segment's no-slower admission boundary intact; a selected GPU segment still +returns before the exact CPU GELU pass. The targeted A/B escape hatch is +`PPOCR_DISABLE_DEPTHWISE_POINTWISE_GELU_FUSION=1`. + +The AVX-512 kernel smoke and the 12/12 decoded-text ONNX Runtime gate passed. +On this shared host, a 15-run `en.ppm` A/B did not establish a uniform +latency benefit: tiny was 29.137 vs 28.908 ms, small 62.292 vs 62.007 ms, +and medium 205.199 vs 221.369 ms (fusion enabled vs disabled). It is retained +because it removes a graph-lifetime boundary and shows a medium improvement, +but the table intentionally does not promote it to a universal CPU speedup. + +### 2026-08-12: expanded batched ordinary-Conv SIMD coverage + +`Conv2dBatch()` now carries the batch index through the existing runtime-gated +SIMD kernels for valid `2x2`, padded `5x5`/`7x7`, and asymmetric +`1x3`/`3x1`/`1x5`/`5x1` stride-one convolutions, in addition to the prior +`3x3` stride-one/two paths. This removes one worker-pool dispatch per crop +for the medium detector's context layers while preserving each output's +increasing-channel/kernel accumulation order. AVX-512 is selected only after +the existing CPUID/XCR0 guard; AVX2 and portable/NEON paths retain their safe +fallback behavior. + +The low-level smoke now compares N=3 batched output against three independent +calls for all of those shapes and ReLU tails. It passed with normal AVX-512 +dispatch and with `PPOCR_DISABLE_AVX512=1` (AVX2 fallback). A post-change +four-identical-page medium CPU batch test (`det_batch_size=4`, +`rec_batch_size=4`, three measured runs) was result-identical and measured +**793.299 ms** serial versus **710.437 ms** batched (**1.117x**). The same +tiny hybrid configuration was result-identical and measured **126.750 ms** +serial versus **85.669 ms** batched (**1.480x**). These are local scheduler +measurements, not a universal Vulkan claim: the concurrent Vulkan primitive +smoke continued to select GPU only for its no-slower affine+Swish probe and +retained CPU for the transfer-bound Conv and GEMM probes. + +The full small-to-large-to-small CPU ladder was rerun for all model sizes with +the expanded kernels. All passed the three 20% bounded-recovery limits. +Observed final-small change from the post-warm baseline was tiny **+1.72%** +and **+8.51%**, small **-1.57%** and **+8.90%**, and medium **+0.70%** and +**+0.02%** over two cycles. `declined_after_largest` is retained as a fact +rather than a pass condition, because Windows heap trimming is nondeterministic +even when the runtime has released the input and activation vectors. + +### 2026-08-12: default AVX-512 wide-context Conv tile + +The AVX-512 eight-output tile for the PP-OCRv6 medium detector's `5x5` and +`7x7` context layers is now enabled by default for its narrow, runtime-checked +shape (`C_in >= 32`, `C_out >= 8`, and both spatial dimensions at least 32). +It reuses each input vector across eight output reductions; smaller shapes, +AVX2, NEON, and scalar targets retain their existing paths. Set +`PPOCR_DISABLE_AVX512_CONV_WIDE8=1` for a deployment-local A/B test. + +On the local AVX-512 host with 12 workers, three warm-ups and twelve `en.ppm` +runs, medium CPU measured **424.234 ms** with the tile and **659.937 ms** with +`PPOCR_DISABLE_AVX512_CONV_WIDE8=1` (same model/input; shared-host variation +is reflected by the recorded medians **404.622 / 668.809 ms**). Fresh +ONNX-Runtime decoded-text comparison remained **12/12** across tiny, small, +and medium on `16x16`, English, low-contrast, and `3000x80` inputs. The medium +two-cycle `64x64 閳?2560x1440 閳?64x64` ladder also passed all bounded-memory +checks, ending at **+0.19%** and **+2.72%** from its warmed baseline. Vulkan +primitive smoke remained numerically passing; hybrid selected only its +measured no-slower affine+Swish and depthwise+Swish samples in that run. + +### 2026-08-12: medium worker and transpose-tile recheck + +A fresh worker sweep after the wide-context default confirms the library's +automatic **16-worker** ceiling remains appropriate for the broad medium +graph, while tiny/small retain their shorter-kernel behavior: on the same +`en.ppm` setup, medium measured **191.664 / 205.187 / 185.906 ms** with +8/12/16 workers; tiny measured **28.434 / 28.797 ms** and small +**57.390 / 59.147 ms** at 12/16 workers. The 16-worker medium CPU retest +(3 warm-ups, 20 runs) averaged **185.325 ms**; paired ONNX Runtime CPU on the +same image/run count averaged **260.194 ms**, a host-specific **28.8%** lower +native latency. + +The AVX-512 four-output `ConvTranspose2x2` FPN experiment was rechecked too. +It measured **186.232 ms** versus **181.971 ms** for the established +single-output implementation (3 warm-ups, 10 runs), so it remains opt-in via +`PPOCR_ENABLE_AVX512_TRANSPOSE2X2_TILE4=1`; it is not promoted merely because +it reduces some input loads. This preserves the faster default and avoids a +regression on the current target. + +### 2026-08-12: device-resident depthwise/pointwise Vulkan segment + +The Vulkan backend now has a numerically checked two-dispatch MobileNet +`depthwise Conv -> 1x1 pointwise Conv` primitive. It uploads the chain input +once, leaves the depthwise feature map in a mapped Vulkan storage buffer, +inserts an explicit compute shader write-to-read memory barrier, and reads +back only the pointwise result. Its hybrid admission measures that complete +boundary against the corresponding CPU `DepthwiseConvBatch` plus +`PointwiseConvBatch` pair and rejects Vulkan when it is slower. + +On the local Radeon 780M / AVX-512 host, the odd-shape batched numerical smoke +passed, but the representative `N=4, C=32, M=40, 31x29, 3x3` full-boundary +probe measured **0.836 ms Vulkan vs 0.271 ms CPU**. Hybrid therefore keeps +the CPU path for this segment. The primitive is deliberately not folded into +the production ONNX graph yet: its current model-level floating-point drift +needs a decoded-text tolerance gate before any performance claim or default +dispatch change. This preserves exact production behavior while retaining a +real, barrier-validated GPU building block for subsequent fully-resident +segments. + +The batch smoke executable now also prints its individual timed samples, so a +throughput claim can be audited for scheduler outliers rather than relying on +one aggregate number. With four equal `en.ppm` pages, batch size four, 16 CPU +kernel workers, two warm-ups and eight timed runs, CPU serial閳妼atch results +were **120.826閳?5.704 ms (1.410x)** for tiny, **281.621閳?27.853 ms (1.236x)** +for small, and **859.114閳?44.174 ms (1.018x)** for medium. Hybrid under the +same batch settings measured **166.786閳?08.215 ms (1.541x)** tiny, +**331.511閳?51.555 ms (1.318x)** small, and **824.029閳?49.212 ms (1.100x)** +medium. Serial/batch OCR outputs were byte-for-byte equivalent in each run. +The hybrid figures are page-batching capacity gains; they do not claim that +the partial Vulkan graph is faster than CPU for every single page. + +A fresh 12-cycle run after this lifetime change used a 23.488 MiB baseline and +finished at 26.664 MiB (+3.176 MiB); its cycle deltas ranged from -0.543 MiB to ++4.055 MiB with no monotonic growth. Windows heap retention makes the final +private-byte delta workload- and allocator-dependent, so the important release +criterion is the non-growing mixed-shape sequence, not a single final number. + +After the batched constant-weight MatMul change, a medium-model two-cycle +mixed-size check covering `16x16`, `3000x80`, `80x3000`, and the 119-box +`1920x1080` UI page used **293,961,728 bytes** after warm-up; the two cycle +measurements were **811,008 bytes below** and **471,040 bytes below** that +baseline. This verifies that flattening a batch is a scheduling change, not a +per-shape tensor cache or an activation-retention increase. As above, it is a +Windows allocator-capacity observation rather than a universal leak proof. + +After adding the Vulkan channel-affine batch buffers, the same medium mixed +sequence was rerun for two cycles with the default hybrid policy. Its +post-warm-up baseline was **290,508,800 bytes**; cycles finished at +**+5,214,208** and **+2,506,752 bytes**. The high-water movement is bounded +Windows allocator retention after the large UI page, not a per-cycle growth +trend; GPU affine admission was rejected on this host, so the extra persistent +Vulkan coefficient storage was not exercised by the CPU execution path. + +After the BatchNorm-Swish in-place activation update, a fresh CPU medium +mixed-size soak (`16x16`, `3000x80`, `80x3000`, and the dense `1920x1080` UI +page) used **286,793,728 bytes** post-warm-up. Its next two cycles were +**9,101,312** and **5,144,576 bytes below** baseline. This is a bounded +allocator observation on Windows, but it confirms the source-buffer reuse does +not retain changing-shape recognition activations. + +The captured C++ and ONNX Runtime reports are +`build/memory_soak_cpp_12.json` and `build/memory_soak_ort_12.json`. A +post-optimization 6-cycle C++ check is also retained as +`build/memory_soak_cpp_parallel4_6.json`: it finished 1.034 MiB below its +24.629 MiB post-warmup baseline, demonstrating that bounded concurrent +recognition does not retain every dynamic input shape. + +### 2026-08-12: cross-page recognition batching + +`OCR::RecognizeBatch` now keeps dynamic detector resizing per page, then +coalesces equal-width crops from all submitted pages into bounded NCHW +recognizer batches. This is useful for both CPU SIMD and the Vulkan batch-Y +dimension; it does not pad unrelated detector pages, does not change result +order, and releases each detector probability map before recognition starts. + +On this Radeon 780M / Windows host, medium PP-OCRv6, four copies of `en.ppm`, +`rec_batch_size=8`, one recognizer worker and one detector worker: + +| Path | Serial pages | Cross-page batched | Speedup | +|---|---:|---:|---:| +| CPU | 773.012 ms | 744.098 ms | 1.039x | +| Hybrid | 854.746 ms | 1249.711 ms | 0.684x | + +The batch smoke test confirms exact public `Result` equivalence with serial +inference. Hybrid is intentionally not presented as a win here: the current +UMA Vulkan implementation admits each segment only when its complete transfer ++ dispatch + readback path is no slower than CPU, while the coalesced workload +still has significant CPU-only graph work. Four-image mixed-size CPU coverage +(`en`, low-contrast, wide strip, dense 1920x1080 UI; 128 results) also passed +the serial-result check at 1.004x. A tiny-model four-page CPU check measured +143.472 ms serial and 139.913 ms batched (1.025x). Re-run these workloads on +the deployment hardware; they are measurements, not portability claims. + +### 2026-08-12: depthwise Vulkan batch kernel and hybrid batch gate + +The Vulkan depthwise-convolution path now maps one workgroup to one NCHW +channel and up to 1,024 output pixels. Its `[KH,KW]` filter is cooperatively +staged in workgroup memory (up to `16x16`), while Vulkan's Y dimension remains +the independent crop-batch dimension. PP-OCRv6's MobileNet-style depthwise +filters therefore avoid reloading the same channel filter for every output +pixel. Larger exported filters safely use the existing global-memory fallback. + +The Radeon 780M numerical smoke test passed for a padded `N=2, C=5, 7x9, +3x3` depthwise batch. Its latest complete synchronous measurement was +**0.44340 ms GPU / 0.35062 ms CPU**, so the strict H2D + dispatch + D2H +admission policy correctly retained the CPU SIMD path for that shape. This is +an optimized, batch-capable GPU primitive, not a claim that the incomplete +GPU-resident OCR graph is faster on this UMA GPU. + +The same build also ran the public batch-equivalence harness on tiny PP-OCRv6 +with `rec_batch_size=8`, one detector worker and one recognizer worker across +four varied pages (`en`, low-contrast, `3000x80`, dense `1920x1080`). All +**129** decoded results matched serial `Recognize()` exactly. The one-shot +local measurement was **1081.928 ms serial / 1167.667 ms batched** for CPU and +**1105.010 ms serial / 1075.921 ms batched** for hybrid. These scheduler +samples are intentionally retained as measurements rather than a universal +throughput promise; the dense mixed-width workload has limited equal-width +crop coalescing. A separate CPU-versus-hybrid dense-page result comparison was +also byte-for-byte identical. + +### 2026-08-12: cross-crop CPU pointwise scheduling + +The CPU 1x1-convolution path now accepts a real NCHW batch in one scheduling +call. On x86 it flattens `(crop N, output-channel tile)` into the persistent +AVX-512/AVX2 worker queue, retaining the existing per-channel FP32 reduction +order and ISA-specific four/eight-output vector kernels. ARM/NEON and scalar +builds retain their portable per-crop path. This removes repeated worker-pool +barriers for batchable recognizer projections without changing the model graph +or requiring ONNX Runtime. + +The strict CPU-versus-ONNX Runtime decoded-text gate passed **4/4** varied +inputs (`en`, `16x16`, low-contrast, `3000x80`) for **tiny, small, and +medium** after this change. The five-page public batch gate (also adding dense +`1920x1080`) passed serial-result equivalence for all three models: tiny +**130**, small **126**, medium **129** results. A local one-worker CPU batch +sample measured **0.948x / 1.162x / 1.014x** page-batch throughput for +tiny/small/medium respectively; the mixed dimensions intentionally make this +an evidence point rather than a universal latency claim. Hybrid revalidation +also preserved exact serial results at **1.003x / 1.036x / 0.983x**. + +On `en.ppm`, 2 warm-ups and 6 timed CPU runs with 16 workers, the current +native means were **44.193 ms / 84.184 ms / 256.530 ms** for tiny/small/medium. +The matched ONNX Runtime CPU samples were **127.640 ms / 244.623 ms / +513.763 ms**, corresponding to **2.89x / 2.91x / 2.00x** native latency +advantages on this host. Windows scheduling remains variable; these are +repeatable local observations, not a portable capacity guarantee. + +The five-size, two-cycle memory soak (`16x16`, `en`, low-contrast, `3000x80`, +`1920x1080`) remained bounded. Its warmed baselines and final deltas were: +tiny **113,876,992 / +3,874,816 bytes**, small **150,462,464 / -2,027,520 +bytes**, and medium **385,916,928 / -3,629,056 bytes**. The small movements are +Windows allocator high-water behavior rather than a leak assertion. + +### 2026-08-12: batched residual 1x1 projection scheduling + +Fused `Conv(1x1) -> Add`, `Conv(1x1) -> Add -> ReLU`, and `Conv(1x1) -> Add +-> Swish` now have NCHW batch kernels. On x86, one work queue covers all +`(crop, output-channel SIMD tile)` tasks: AVX-512 uses the established +four/eight-output tiles and AVX2 uses four-output tiles. ARM/NEON and scalar +builds safely retain the per-crop implementation. The Swish variant completes +the batched fused convolution/add first, then applies the existing vector +Swish once across the whole contiguous NCHW allocation; FP32 reduction and +activation order are unchanged. + +`ppocr_kernel_smoke` verifies the new Add, Add+ReLU, and Add+Swish batch +kernels against their single-crop counterparts for both SIMD-tail and large +work cases. It also passed with `PPOCR_DISABLE_AVX512=1`, exercising the AVX2 +fallback. `PPOCR_DISABLE_RESIDUAL_POINTWISE_BATCH=1` is available solely as a +per-process A/B escape hatch; it restores the prior per-crop calls. + +The four-image decoded-text comparison with ONNX Runtime remained **4/4** for +each tiny, small, and medium model. The five-size public batch-equivalence +gate also matched all serial `Result`s exactly: tiny **130**, small **126**, +medium **129**. One local CPU sample (one detector/recognizer worker, +`rec_batch_size=8`) measured serial/batch times of **909.483/907.159 ms** +(tiny, **1.003x**), **2780.569/2882.623 ms** (small, **0.965x**), and +**6781.126/6750.499 ms** (medium, **1.005x**). Mixed crop widths limit +coalescing, so these are recorded measurements rather than a portability +claim. Hybrid correctness was retained on the same corpus: tiny **1.134 s / +1.132 s** (0.994x), small **3.978 s / 3.515 s** (1.132x), and medium **7.024 s +/ 7.464 s** (0.941x). The hybrid backend still admits each Vulkan segment only +after a complete transfer + dispatch + readback no-slower check; the project +does not claim a fully GPU-resident graph or enable `gpu_only`. + +### 2026-08-12: cross-crop CPU depthwise scheduling + +The MobileNet depthwise CPU fallback now accepts the leading NCHW batch +directly. It flattens independent `(crop, channel)` jobs into one persistent +worker-pool pass, while each job continues to use the existing runtime-selected +AVX-512, AVX2, NEON, or scalar depthwise kernel. This removes repeated batch +loop scheduling around the dominant depthwise backbone stages without changing +the per-channel FP32 multiply/add order. The Vulkan depthwise route remains +separate and still receives the entire NCHW batch in one dispatch whenever its +complete transfer + dispatch + readback admission measurement is no slower +than CPU. + +The extended kernel smoke tests padded/stride-1 `3x3` and padded/stride-2 +`5x5` depthwise batches against the established per-image implementation; both +the normal AVX-512 run and `PPOCR_DISABLE_AVX512=1` AVX2 fallback passed. The +four-image decoded-text comparison with ONNX Runtime remained **4/4** for each +tiny, small, and medium model. The five-size batch-result gate likewise +remained exact (tiny **130**, small **126**, medium **129** results). + +On the varied five-page corpus with `rec_batch_size=8` and one recognition +worker, this local CPU sample measured serial/batch throughput of **1.096x** +(tiny: 1000.988/913.176 ms), **0.992x** (small: 2855.215/2878.902 ms), and +**1.006x** (medium: 6922.651/6881.270 ms). Crop-width diversity constrains +batch density, so the figures are intentionally recorded as host-specific +measurements. Hybrid preserved serial-result identity at **1.011x**, **1.058x** +and **0.924x** for tiny/small/medium; GPU segments were retained only when the +strict no-slower admission test passed. A renewed five-size/two-cycle memory +soak stayed bounded: tiny baseline **99,737,600**, final **+716,800** bytes; +small baseline **148,520,960**, final **+1,306,624** bytes; medium baseline +**384,311,296**, final **-3,907,584** bytes. + +### 2026-08-12: batched ordinary 3x3 convolution scheduler + +The group-1 non-pointwise convolution path now supports NCHW batches. For the +common `3x3` stride-1 and stride-2 OCR shapes it flattens crop and established +AVX output-channel tiles into one persistent-pool submission: AVX-512 retains +its four/eight-output tile selection; AVX2 retains four-output stride-1 tiles +and its stride-2 kernel. ARM/NEON and non-3x3 geometries continue through the +existing per-image `Conv2d` path. This changes scheduling only, not the output +channel reduction order. `PPOCR_DISABLE_CONV_BATCH=1` restores the previous +per-crop dispatch for deployment A/B work. + +The extended kernel smoke checks stride-1 tail, large AVX-512 tile, and +stride-2 ReLU batches against the prior single-image path; both AVX-512 and +forced AVX2 runs pass. ONNX Runtime decoded-text comparisons again passed +**4/4** for each tiny/small/medium model. On the five-size corpus with one +recognizer worker and `rec_batch_size=8`, the latest CPU serial/batch samples +were tiny **839.965/822.967 ms** (1.021x), small **2602.329/2656.020 ms** +(0.980x), and medium **6507.553/6500.383 ms** (1.001x), all with exact public +batch results. A consecutive A/B sample with `PPOCR_DISABLE_CONV_BATCH=1` +measured **1.023x / 0.966x / 1.005x** on the same mixed-width suite; host noise +and limited same-width coalescing outweigh this small scheduling change there, +so no universal speedup is claimed. Hybrid result equivalence held at +**1.009x / 0.778x / 0.979x**; Vulkan continues to be selected only by its +complete no-slower segment measurement. + +### 2026-08-12: batched pointwise HardSwish projection + +The remaining fused `1x1 Conv -> HardSwish` CPU path now shares the existing +cross-crop pointwise SIMD scheduler. It performs all NCHW projections through +`PointwiseConvBatch`, then runs one contiguous exact HardSwish pass over the +final allocation, instead of issuing the projection/activation once per crop. +This preserves the Conv FP32 reduction order and the canonical HardSwish +formula; AVX-512, AVX2, NEON, and scalar dispatch remain runtime portable. + +Kernel smoke now compares both tail and large batched HardSwish projections to +the established per-crop routine. Normal AVX-512 and forced AVX2 execution +passed. The four-input ONNX Runtime decoded-text gate again passed **4/4** for +tiny, small, and medium, and the varied five-page batch gate remained exactly +identical to serial results (130 / 126 / 129 results). Latest CPU +serial/batch samples on that suite were tiny **901.083/842.421 ms** (1.070x), +small **2515.113/2599.535 ms** (0.968x), and medium +**6177.222/6239.080 ms** (0.990x). Hybrid samples were **0.996x / 1.250x / +0.972x**. These mixed-width measurements are evidence, not portability +claims; each Vulkan segment continues to require its own complete no-slower +transfer/dispatch/readback admission. + +### 2026-08-12: batched FPN 2x2 transposed convolution + +The detector's `2x2`, stride-two `ConvTranspose` FPN fast path now accepts +NCHW batches. It flattens `(crop, output-channel tile)` into one scheduling +pass: AVX-512 keeps its optional four-output reuse tile (or one-output default) +and AVX2 uses its established channel kernel; ARM/scalar builds retain the +same portable per-image routine. This preserves each output channel's ordered +input-channel accumulation and eliminates repeated batch-loop scheduling. + +`ppocr_kernel_smoke` now validates small tail and large square batch cases +against the prior per-image FPN kernel, on both normal AVX-512 and forced AVX2 +paths. The tiny/small/medium ONNX Runtime decoded-text checks again passed +**4/4** each. The five-size public batch gate stayed serial-identical at +130/126/129 results. Latest CPU serial/batch observations were tiny +**808.237/821.381 ms** (0.984x), small **2467.217/2557.340 ms** (0.965x), and +medium **6063.649/6071.106 ms** (0.999x). This page mix does not batch detector +shapes and has diverse recognition widths, so it should not be read as a +universal throughput claim. Hybrid exact-result samples were **1.019x / 0.859x +/ 0.974x**. The renewed medium five-size/two-cycle soak remained bounded +(baseline **384,970,752** bytes; final delta **+3,231,744** bytes), and Vulkan +smoke retained strict complete-segment admission. + +### 2026-08-12: batched ordinary-convolution Vulkan path + +Vulkan hybrid execution now also covers ungrouped, non-dilated ordinary NCHW +convolution (`3x3` and `2x2` detector forms), in addition to the existing +pointwise and depthwise paths. The new shader maps a real crop batch to its +Y dimension and writes four adjacent output values per invocation where +possible. Learned `[M,C,KH,KW]` weights and `[M]` bias retain their compact +layouts and are cached for immutable ONNX initializers; an immediately fused +ReLU can complete before the only D2H copy. Asymmetric-stride, grouped, and +dilated convolutions deliberately retain the established CPU SIMD path. + +This remains a *hybrid* primitive, not a GPU-only claim. Every shape is +first validated against the CPU batched convolution and admitted only when its +complete H2D + dispatch + fence wait + D2H time is no slower. The new Vulkan +smoke test covers padded stride-one and stride-two `N=3,C=4,M=7,3x3` batches, +including fused ReLU and scalar output tails. On the local AMD Radeon 780M, +the larger admission sample (`N=4,C=24,M=40,31x29,3x3,ReLU`) measured +**3.53696 ms GPU / 0.83228 ms CPU** after the shared-filter tile optimization, +so the production policy correctly kept +that shape on CPU rather than adding GPU overhead. + +After the change, the five-size public batch-equivalence harness preserved +serial output identity for all official model sizes under `PPOCR_BACKEND=hybrid` +with recognizer batch size 8: tiny **130** results (**1188.492 / 1163.981 ms**, +**1.021x** serial/batch), small **126** (**3425.233 / 3507.859 ms**, **0.976x**), +and medium **129** (**7949.857 / 8198.539 ms**, **0.970x**). These are +host-specific mixed-size scheduler samples, not a universal GPU-performance +promise. `gpu_only` remains unavailable until the entire detector and +recognizer graph is device-resident. + +### 2026-08-12: final-use BatchNormalization storage reuse + +Standard inference `BatchNormalization` nodes now use the same NCHW +channel-affine kernel as fused normalization paths. When graph liveness +proves that the input has reached its final use, the executor applies the +precomputed `scale / sqrt(variance + epsilon)` and `bias - mean * scale` +directly in that dying allocation, then renames it to the output. This avoids +one complete activation allocation and copy for each eligible unfused node. +The official model bundle folds most normalisation nodes at load time, so this +extends compatible PP-OCRv6 graph coverage rather than being represented as a +separate current-model speedup. The new +`BatchNormAffine` primitive is alias-safe and dynamically dispatches through +AVX-512, AVX2, NEON, or scalar `ScaleShift`; it is used in both `Run()` and +the recognizer's real `RunCtcTop1()` path. `PPOCR_DISABLE_BATCHNORM_INPLACE=1` +is available for deployment A/B checks. + +Kernel coverage now includes separate out-of-place and in-place batch-affine +numeric tests, and passed with both default AVX-512 dispatch and forced AVX2. +The post-change C++/ONNX Runtime decoded-text gate passed **4/4** varied +images (`16x16`, normal English, `3000x80` strip, noisy low-contrast) for +both tiny and medium. A five-size medium two-cycle memory soak remained +bounded at a **457,703,424-byte** post-warm-up baseline; cycles ended at +**-9,195,520** and **+1,744,896 bytes**, consistent with allocator +high-water reuse rather than per-cycle growth. The same five-size hybrid +tiny batch equivalence test returned all **130** decoded results identically +to serial inference (**1123.880 / 1118.024 ms**, **1.005x** serial/batch). +These are validation measurements, not a claim that every normalisation node +or GPU segment is faster on every host. + +### 2026-08-12: batched Vulkan FPN transpose-convolution path + +The detector FPN's `ConvTranspose(2x2, stride=2)` projection now has a +dedicated batched Vulkan primitive. Its no-padding geometry has no overlap +between output tiles, so each output pixel maps directly to one input pixel +and one `[Cin,Cout,2,2]` filter tap; this avoids an expanded intermediate. +The kernel accepts NCHW batches, caches immutable model parameters in the +persistent Vulkan context, and uses one output readback. The command +dispatcher was also corrected to submit workgroups (256 four-float +invocations per group), rather than accidentally submitting that many times +the required groups. + +The hybrid executor now recognizes this exact ONNX form and uses it only +after an end-to-end CPU comparison for the exact batch/shape. The comparison +includes H2D, dispatch, fence wait, D2H, and FP32 output validation; rejected +shapes continue through the AVX-512/AVX2/NEON/scalar CPU kernel with no output +change. Vulkan smoke now validates an odd-size `N=3,Cin=5,Cout=7,11x13` +batch against scalar FP32 reference values, including its vector tail. + +On the local AMD Radeon 780M, the FPN admission sample +(`N=4,Cin=32,Cout=40,31x29`) measured **2.48820 ms GPU / 0.60534 ms CPU**, +so it was correctly rejected rather than being presented as an OCR speedup. +The post-change five-size tiny hybrid batch-equivalence run remained exactly +serial-identical with **130** decoded results and measured +**1098.189 / 1079.664 ms** serial/batch (**1.017x**). This is a real +mixed-size batch validation on this host, not a general GPU throughput claim. +`gpu_only` remains unavailable until the full detector and recognizer graphs +can stay device-resident. + +### 2026-08-12: FPN transpose shared-filter GPU tile and multi-model batch gate + +The Vulkan FPN transpose primitive now selects a shared-filter workgroup form +when its `[Cin,2,2]` row fits the 4,096-float local-memory budget. A +workgroup stages the non-contiguous ONNX `[Cin,Cout,2,2]` row into contiguous +shared memory once, then computes a 1,024-pixel tile for one output channel. +The staging explicitly preserves the original increasing-input-channel FP32 +reduction order. Wider exported layers retain the generic batch kernel. The +odd `N=3,Cin=5,Cout=7,11x13` Vulkan numerical test continues to compare every +result with scalar reference values. + +On the local Radeon 780M, the complete-transfer FPN admission sample improved +from the preceding **2.48820 ms** to **2.15242 ms GPU**; CPU measured +**0.45748 ms**, so hybrid still correctly selects CPU for that isolated node. +This is intentional: hybrid uses Vulkan when the measured complete segment is +equal or faster, rather than increasing CPU offload at the cost of latency. + +The five-size public hybrid batch gate (`16x16`, normal English, +low-contrast, `3000x80`, and dense `1920x1080`; recognizer batch 8, one +recognizer worker) remained serial-identical for all official models: small +**126** results (**2751.279 / 3384.936 ms**, **0.813x**) and medium **129** +results (**7358.610 / 7808.435 ms**, **0.942x**) in this shared-host sample; +tiny's same gate was **130** results (**1098.189 / 1079.664 ms**, **1.017x**). +The C++/ONNX Runtime medium decoded-text gate also passed **4/4** distinct +sizes/aspect ratios (`16x16`, English, low-contrast, wide strip). The +repository's paired benchmark scripts now accept `-Model tiny|small|medium`, +and `bench/compare_models.ps1` runs all three across the same five-size corpus +for deployment-specific ORT comparison. Mixed-size batching is not asserted +as a universal speedup; output equivalence and bounded work are the gate. + +For a fresh paired single-page sanity sample after this GPU-tile change +(`en.ppm`, two warm-ups, five runs, 16-thread CPU budget, CPUExecutionProvider +for ONNX Runtime), all three official sizes remained faster than ORT: + +| Model | C++ hybrid mean | ORT CPU mean | C++ improvement | +|---|---:|---:|---:| +| tiny | 95.490 ms | 128.475 ms | 25.67% | +| small | 157.035 ms | 270.218 ms | 41.89% | +| medium | 263.851 ms | 478.374 ms | 44.84% | + +The host is shared and short-run tiny measurements have greater variance; the +table is current measured evidence, not a portable guarantee. It uses the +same complete detector+recognizer OCR work in both implementations. + +### 2026-08-12: terminal CTC guard and scalar-reference coverage + +`RunCtcTop1()` already avoids materializing the terminal +`[N,T,6906]` Softmax activation: it keeps final logits, computes only CTC +top-1 indices and probabilities for emitted characters, then releases the +logits at function exit. This revision narrows the fast-path eligibility to +a verified class-axis terminal Softmax (`axis=-1` or `axis=2`) on the official +`[N,T,V]` exports; a terminal Softmax over any other axis now fails fast rather +than silently applying CTC semantics to the wrong dimension. The low-level +kernel smoke now compares SIMD-dispatched CTC against a scalar reference for +both a tail-heavy `N=3,T=17,V=31` case and production-width +`N=4,T=41,V=6906`, including blank and repeated-token paths. + +Validation after the guard: the expanded CTC kernel smoke passed under both +default AVX-512 dispatch and forced AVX2; C++/ONNX Runtime decoded text passed +**4/4** diverse inputs for tiny and small, while the preceding medium gate was +also **4/4**. The five-size tiny hybrid batch gate remained serial-identical +at **130** results (**1207.436 / 1297.085 ms**, **0.931x** on this shared +host). A medium five-size/two-cycle memory soak stayed bounded at a +**449,376,256-byte** post-warm-up baseline; cycles ended at **+7,770,112** and +**+5,087,232 bytes**, which is allocator high-water reuse rather than monotonic +per-cycle growth. Radeon 780M Vulkan smoke remained numerically passing; its +full-transfer policy continued to select GPU only for shapes that measured no +slower than CPU. + +### 2026-08-12: hybrid detector batch admission and benchmark controls + +`RecognizeBatch()` now permits its existing exact-shape detector NCHW batches +when `Backend::hybrid` is selected as well as on CPU. This does not change +resize semantics or pad differently sized pages: pages are still grouped only +when their independently calculated detector width and height match exactly. +Every Vulkan operator continues to make a separate batch-shape admission +decision that includes H2D, dispatch, fence wait, D2H, and numerical +validation. A rejected operator uses its CPU SIMD batch kernel, so enabling a +larger detector batch never forces a slower partial-GPU path. + +`ppocr_bench` now reads `PPOCR_DET_BATCH_SIZE`; `ppocr_batch_smoke` also +reports both effective detector and recognizer batch sizes (and accepts +`PPOCR_REC_WIDTH_BUCKET`). This makes the public batch path reproducible for +deployment A/B work. + +On the local Radeon 780M system, eight equal `en.ppm` pages, one page worker, +`rec_batch_size=8`, and `det_batch_size=8` remained exactly serial-equivalent. +One fresh steady-state sample measured CPU **296.587 / 181.402 ms** +(**1.635x**) and hybrid **343.533 / 219.900 ms** (**1.562x**) for serial versus +batched execution. Hybrid with `det_batch_size=1` measured **274.675 / +232.065 ms** (**1.184x**) in a separate run, so this host benefited from +allowing the same-shape detector batch. These are host-specific measurements, +not a claim that every GPU or page mix will have the same ratio. + +Regression coverage after the change: normal and AVX2-forced +`ppocr_kernel_smoke` passed; the Vulkan primitive smoke passed on AMD Radeon +780M; and decoded text matched ONNX Runtime for all four varied images in each +of tiny, small, and medium (**4/4 per model**). `gpu_only` remains explicitly +unavailable until the full detector and recognizer graph is device-resident. + +### 2026-08-12: fused Vulkan FPN resize/add batch primitive + +The FPN's graph-proven `Resize(nearest, 2x) -> Add(lateral)` sequence now has +a Vulkan `NCHW` batch primitive. It uploads the small source map and lateral +residual once, generates each nearest-neighbour value and sums it in one +shader dispatch, then reads only the completed result. The short-lived +expanded resize tensor is therefore never materialized on either CPU or GPU. +Odd dimensions and four-page batch addressing are covered by the Vulkan +smoke test. + +Hybrid admission is shape-specific and strict: the measured path includes +source/residual H2D copies, shader dispatch, fence wait, D2H copy, and every +FP32 output comparison against `NearestResize2xAdd`. On this AMD Radeon 780M, +the representative `N=4,C=24,31x29` probe measured **0.47230 ms GPU** versus +**0.06686 ms CPU**, so it is correctly retained on AVX-512 CPU rather than +being forced onto the GPU. This primitive is nevertheless batch-ready for +hardware where the complete path wins. + +Post-change validation: default and forced-AVX2 kernel smoke passed; Vulkan +smoke passed; tiny CPU and hybrid decoded-text comparison against ONNX Runtime +passed **4/4** varied inputs; and CPU tiny five-size/two-cycle memory soak +finished at **-139,264** and **-13,721,600 bytes** relative to a +**146,825,216-byte** post-warm-up baseline. A fresh eight-identical-page, +batch-8 smoke sample was exact-equivalent to serial: CPU **303.220 / 181.519 +ms (1.670x)** and hybrid **336.976 / 213.733 ms (1.577x)**, serial/batched. +For a single `en.ppm` page with batch sizes one, CPU averaged **37.206 ms**; +hybrid averaged **37.649 ms**, so this shared host's current partial offload +does not claim a whole-pipeline GPU gain. `gpu_only` remains unavailable until +the entire detector and recognizer graphs are device-resident. + +### 2026-08-12: recognizer CTC-path lifetime and Vulkan GEMM coverage + +The production `RunCtcTop1()` recognizer executor now directly runs fused +`1x1 Conv + shortcut` nodes, matching the ordinary executor rather than +falling through its generic node path. This removes graph-input-vector setup +on the dense residual path and releases the source feature map immediately +after the fused kernel writes its destination. It is shared by tiny, small, +and medium; the three-model CPU/hybrid decoded-text regression against ONNX +Runtime remained **4/4 per model** over tiny, normal English, noisy +low-contrast, and ultra-wide input dimensions. + +Vulkan additionally now implements row-major projection GEMM (`[R,K] x +[K,C] + bias`) for recognizer attention and CTC-head-compatible layouts. It +has a numerical smoke for odd `37x29x103` dimensions and a strict full-boundary +admission probe. The Radeon 780M measured the representative `64x128x512` +case at **0.67616 ms GPU** versus **0.15548 ms CPU**, so hybrid correctly keeps +this shape on CPU. The same smoke measured GPU wins for selected batch +depthwise and affine+Swish shapes, which hybrid admits automatically. This +keeps GPU work data-driven and prevents an isolated GPU primitive from +silently increasing complete-OCR latency. + +The AVX-512 FPN resize/add kernel was also tightened to load one contiguous +16-float source vector per iteration before two indexed broadcasts; default +and forced-AVX2 kernel smoke pass. On a fresh 16-worker `en.ppm` run (three +warmups, ten timed runs), CPU means were **33.535 / 68.351 / 215.205 ms** and +hybrid means **32.155 / 76.156 / 258.877 ms** for tiny/small/medium. Current +paired ONNX Runtime means from the same session were **176.288 / 229.349 / +572.251 ms**, so CPU remains the deployment recommendation for small/medium +on this UMA GPU while retaining a large native-vs-ORT advantage. + +A five-size tiny batch gate (`16x16`, English, low contrast, `3000x80`, dense +`1920x1080`; batch 8) returned all **130** results identically. This mixed +corpus measured **874.808 / 987.314 ms** CPU serial/batched and **1096.915 / +1107.025 ms** hybrid serial/batched, demonstrating that heterogeneous work is +not mislabeled as a throughput win. Its two-cycle memory soak stayed below its +**146,587,648-byte** post-warm-up baseline by **14,483,456** and +**14,401,536 bytes**. `gpu_only` remains explicit-unavailable until complete +detector and recognizer device residency is implemented and verified. + +### 2026-08-12: CTC residual GPU admission and true page-batch validation + +`RunCtcTop1()` is the production recognizer path, so its fused `1x1 Conv + +shortcut` blocks now use the same batched Vulkan admission path as the generic +executor. This closes a policy gap where recognizer residual blocks could not +be considered for hybrid execution even when their exact NCHW batch shape had +already been measured. The decision remains conservative and shape-local: +Vulkan is used only after the full input/residual upload, dispatch, fence wait, +readback, and CPU-SIMD numerical check are no slower than the CPU block. + +The change was verified on AMD Radeon 780M with kernel SIMD smoke, Vulkan +primitive smoke, and identical decoded CPU OCR output. A four-page equal-size +tiny batch (`4 x en.ppm`, `det_batch=4`, `rec_batch=4`, one page-scheduler +worker) returned all eight text lines identically and measured: + +| Backend | Serial pages | True NCHW page/crop batch | Speedup | +|---|---:|---:|---:| +| CPU | 148.554 ms | 91.244 ms | 1.628x | +| Hybrid | 138.904 ms | 94.528 ms | 1.469x | + +This is a same-shape batching result, not a claim for arbitrarily mixed page +sizes. The existing scheduler still groups detector inputs only when their +native PP-OCR resize shape matches and buckets recognizer crops by padded +width, avoiding semantic changes from artificial image padding. + +Fresh `en.ppm` end-to-end measurements (16 CPU workers, 3 warmups, 10 timed +runs) show the native engine remains faster than the paired CPU ONNX Runtime +baseline. These are host-specific AMD Radeon 780M / AVX-512-host measurements, +not portable guarantees: + +| Model | C++ CPU | C++ hybrid | ORT CPU | CPU latency reduction vs ORT | +|---|---:|---:|---:|---:| +| tiny | 38.215 ms | 37.812 ms | 127.162 ms | 69.9% | +| small | 78.114 ms | 76.542 ms | 220.022 ms | 64.5% | +| medium | 220.072 ms | 240.608 ms | 487.076 ms | 54.8% | + +The medium hybrid result is intentionally reported as slower than CPU. Its +individual Vulkan segments may still be admitted only where their complete +boundary beats SIMD; varying transfer/cache pressure on this shared UMA host +can make end-to-end hybrid slower. `gpu_only` still fails explicitly because +the entire PP-OCRv6 graph is not yet Vulkan-resident. + +### 2026-08-12: default CPU worker budget tuned for PP-OCR batches + +The persistent SIMD worker pool now defaults to **12** workers (still +overrideable with `PPOCR_BENCH_THREADS`). This is a measured scheduling/cache +decision, not a hardware-core-count assumption: on the local AVX-512 host, +the default PP-OCR graph's short detector/recognizer channel tiles saturated +useful memory bandwidth before 16 workers and the extra threads made all three +model sizes slower. The public crop scheduler default is aligned to the same +12-worker budget, avoiding nested page-level oversubscription. + +On `en.ppm` with CPU-only execution, three warmups and eight timed runs, the +thread sweep measured the following mean end-to-end latency: + +| Model | 8 workers | 12 workers (new default) | 16 workers | +|---|---:|---:|---:| +| tiny | 30.140 ms | 32.457 ms | 35.257 ms | +| small | 70.752 ms | 62.472 ms | 71.507 ms | +| medium | 226.918 ms | 215.528 ms | 226.332 ms | + +Tiny stays fastest at eight workers on this host, while the new default gives +the best balanced small/medium result and avoids the former 16-worker +regression. Deployments optimizing only tiny can use +`PPOCR_BENCH_THREADS=8`; larger-server CPUs can continue to tune the existing +override. + +Post-change validation covered default and forced-AVX2 kernel smoke, Radeon +780M Vulkan smoke, all three `en.ppm` models, and true NCHW batches. The +five-size corpus (`16x16`, English, low contrast, `3000x80`, dense +`1920x1080`) decoded **130** tiny-model results identically in CPU and hybrid +batch scheduling. Its CPU serial/batched timing was **446.898 / 408.895 ms**; +hybrid was **805.625 / 440.226 ms**. The two-cycle tiny memory soak over that +same five-size corpus ended **10,407,936** and **11,051,008 bytes below** its +128,106,496-byte post-warm-up baseline. + +### 2026-08-12: fused Vulkan recognizer GEMM + Swish + +The Vulkan recognizer projection primitive now has a `GEMM + Swish` mode for +the graph-fused MLP projection. It accepts the flattened rows of a real crop +batch, caches immutable weights/biases as before, and applies the exact Swish +while writing the GPU result. This removes the former complete CPU-side Swish +traversal after a successful hybrid GEMM dispatch. The shader path is covered +by an odd-tail `41x29x103` numerical smoke case and an end-to-end admission +probe against CPU SIMD `GEMM + Swish`; hybrid still uses it only when the full +upload, dispatch, fence, and readback time is no slower. This is additional +batch-aware GPU coverage, not a claim that the complete PP-OCR graph is yet +device-resident or that `gpu_only` is available. + +Validation after the change passed the normal and forced-AVX2 kernel smoke +suites, plus the Radeon 780M Vulkan suite (including the new numerical +GEMM+Swish tail case). On that smoke run the complete-boundary GEMM+Swish +probe measured **0.65962 ms GPU vs 0.15050 ms CPU**, so the dynamic policy +correctly retained CPU for that transfer-bound shape. Tiny-model decoded-text +comparison against ONNX Runtime again passed **4/4** diverse inputs. Four +identical `en.ppm` pages also remained serial-equivalent: CPU measured +**151.283 / 103.396 ms (1.463x)** serial/batched, hybrid +**133.678 / 109.307 ms (1.223x)**. These are local samples; the stricter +per-segment admission rule remains the GPU performance authority. + +### 2026-08-12: terminal CTC projection memory experiment + +The recognizer executor now contains an optional experimental +`PPOCR_ENABLE_FUSED_TERMINAL_CTC=1` path that computes a terminal +`MatMul(+bias) -> Softmax -> CTC Top-1` directly from one reusable vocabulary +row buffer. It eliminates the transient `[N,T,V]` logits allocation and +preserves the dense projection's K-order plus exact selected-class Softmax +probability. It is deliberately opt-in: on the local AVX-512 CPU the scalar +vocabulary-row implementation is not a stable latency win for every official +model, although it is useful for memory-constrained deployments and passed +the text regression on the exercised corpus. The default continues to use the +proven SIMD GEMM plus vectorized CTC scan until a native SIMD fused terminal +kernel demonstrates a three-model speedup. + +The row-buffer path is now covered in the SIMD kernel smoke with both a +small odd-tail projection and a `4x41x6906` recognizer-sized projection. +The portable regression corpus was also expanded beyond the original four +shapes: blank `800x600`, English and CJK single lines, a mixed three-line +receipt, and two-line CJK all decode with ONNX Runtime text parity for tiny, +small, and medium (**15/15 per model**). Deliberately adversarial rotation and +extreme portrait-strip images are retained as diagnostic samples, but are not +used as decoded-text parity gates because the two independently implemented +detector postprocessors can select different unstable low-confidence boxes. + +### 2026-08-12: cooperative Vulkan GEMM tile and larger page batches + +The Vulkan recognizer GEMM now has a cooperative **8-row 鑴?128-column** FP32 +tile for ordinary (non-Swish) projections. Each workgroup stages a 16-wide K +slice of A and B, reusing B across eight rows rather than rereading it per +output element. The kernel keeps K tiles in ascending order, retains the +existing scalar-tail path, and is selected only after the existing exact +CPU-versus-full-boundary admission check. `gpu_only` remains unavailable: this +is a batch-aware primitive within the hybrid executor, not a device-resident +PP-OCR graph. + +The new path is covered by Vulkan numerical smoke with a tail-heavy +`13鑴?7鑴?73` GEMM (rows, K, columns), in addition to the existing odd-tail and +GEMM+Swish cases. Normal SIMD smoke and Vulkan smoke passed on the local +AVX-512 / Radeon 780M host. Hybrid decoded-text parity against ONNX Runtime +again passed 4/4 diverse inputs for both tiny and medium (`16x16`, English, +low-contrast, and `3000鑴?0`). + +For an eight-page same-shape `en.ppm` batch with `det_batch_size=8`, +`rec_batch_size=8`, and one recognizer scheduler worker, the post-change +hybrid measurements were tiny **304.188 / 225.182 ms (1.351x)** and medium +**2029.114 / 2019.849 ms (1.005x)** serial/batched. A four-shape hybrid batch +gate (`16x16`, English, low-contrast, `3000鑴?0`; batch sizes 4) remained +serial-identical for all models: tiny **186.390 / 176.957 ms (1.053x)**, small +**379.836 / 371.670 ms (1.022x)**, medium **1209.497 / 1215.288 ms (0.995x)**. +These are one host's steady-state samples, not a universal GPU claim; the +per-shape GPU admission continues to reject transfer-bound work. + +After the latest pass, default CPU/hybrid batch regression again produced +serial-identical results across four different page shapes (`16x16`, English, +low-contrast, and `3000x80`). With bounded `det_batch_size=4` and +`rec_batch_size=4`, the local CPU/hybrid batch timings were tiny +**176.722/185.384** and **170.369/165.231 ms**; small **343.559/301.114** and +**374.170/293.868 ms**; medium **1317.190/1291.101** and +**1163.054/1122.104 ms**. A medium two-cycle varied-size memory soak started +at **495,898,624 bytes** after warm-up and ended **9,752,576** then +**10,174,464 bytes below** that baseline. These are host-local measurements, +not a general ONNX Runtime comparison claim. + +### 2026-08-12: optional PP-OCRv6 vector GELU validation + +The existing optional recognizer vector tanh-GELU path +(`PPOCR_APPROX_GELU=1`) was revalidated on AVX-512/AVX2; NEON/scalar retains +its portable fallback. This removes scalar `erf` from the MLP activation hot +path. The exact-Erf ONNX path remains the default, and the model-specific +vector path was checked against ONNX Runtime decoded text rather than being +assumed numerically interchangeable. + +With 12 worker threads, three warmups and ten `en.ppm` runs, the scalar-Erf +baseline measured **29.097 / 60.268 / 202.201 ms** for tiny/small/medium; the +optional vector path measured **23.577 / 53.054 / 191.974 ms** in the same +session (**19.0% / 12.0% / 5.1%** lower mean latency). A longer shared-host +30-run medium sample was noisier, so the 10-run paired sweep is recorded as +an optimization signal, not a portable latency guarantee. + +The decoded-text parity gate passed **4/4** diverse dimensions against ONNX +Runtime for each official model size (tiny, small, medium): `16x16`, English, +low-contrast, and `3000x80` ultra-wide. CPU and hybrid also produced identical +Chinese tiny-model text for the CJK sample. The kernel smoke still passes with +normal AVX-512 dispatch and forced AVX2 fallback. + +### 2026-08-12: AVX-512 batch-GEMM dispatch refinement + +The AVX-512 dense-GEMM path now selects its four-row by 64-column micro-kernel +per projection shape instead of applying its extra register pressure to every +recognizer tier. It stays enabled only for `K >= 384` (and can be disabled for +A/B with `PPOCR_DISABLE_AVX512_GEMM4ROW=1`); AVX-512 閳?AVX2 閳?scalar/NEON +runtime dispatch remains unchanged for all x86 and Arm targets. This keeps +large medium-model projections eligible to reuse each immutable B vector over +four output rows, while tiny/small use the lighter proven path. + +Fresh `en.ppm` CPU measurements (three warm-ups, ten runs, 12 kernel workers) +were tiny **29.699 ms**, small **59.577 ms**, and medium **196.789 ms**. The +previous all-shape four-row experiment measured small **82.637 ms** and medium +**267.150 ms** in the same benchmark configuration, so the new admission +guard is retained. A dense `1920x1080` medium page (122 boxes, +`rec_batch_size=4`, `rec_parallelism=4`, one warm-up, three runs) measured +**4,496.430 ms** with the wide tile enabled and **4,426.272 ms** with it +disabled; therefore the dense-page default now avoids that tile whenever its +projection depth is below the measured `K=384` cutoff. These are +host-local figures, not an ONNX Runtime claim. + +The normal AVX-512 kernel smoke passed after the change, as did the complete +Radeon 780M Vulkan smoke suite. The latter again verified all GPU batch +primitives numerically and dynamically admitted only full-boundary winners: +affine+Swish **0.17342 vs 0.34950 ms**, depthwise **0.34814 vs 0.47170 ms**, +depthwise+Swish **0.35624 vs 0.60330 ms**, and depthwise+HardSwish +**0.34528 vs 0.41760 ms** (GPU vs CPU). Transfer-bound GEMM and other +primitives stayed on CPU; `gpu_only` is still explicitly unavailable until +the complete PP-OCR graph is device-resident. + +### 2026-08-12: diverse-size regression and preprocessing arithmetic reduction + +The preprocessing resize path now folds PP-OCRv6's fixed input normalization +into precomputed per-channel affine coefficients. It keeps the existing +bilinear rounding, RGB-to-BGR layout, detector mean/std, and recognizer +`[-1,1]` arithmetic, while removing three per-pixel floating-point divisions +from detector and crop preparation. This applies to serial OCR and true +`[N,3,H,W]` detector/recognizer batches, without adding a temporary image +buffer or changing the x86 AVX-512/AVX2/scalar/NEON runtime dispatch. + +The post-change ONNX Runtime decoded-text gate passed **8/8** diverse PPM +sizes for every official model (**24/24 total**): `16x16`, English, noisy +low-contrast, `3000x80`, English/CJK single lines, mixed text, and CJK. A +four-page CPU batch smoke across the smallest, normal, low-contrast, and +ultra-wide samples remained byte-for-byte result equivalent to serial OCR +and measured **190.614 / 176.096 ms (1.082x)** serial/batched for tiny. +This explicitly exercises multiple aspect ratios rather than using a +same-page-only batch claim. + +A fresh `en.ppm` three-warmup/ten-run snapshot (12 kernel workers) measured +CPU tiny **35.073 ms**, small **72.582 ms**, medium **244.095 ms**; hybrid +measured **34.887 / 72.036 / 244.847 ms**. The hybrid implementation still +selects Vulkan only after per-shape numeric validation of the complete +upload, dispatch, fence, and readback boundary; therefore it may reduce CPU +work without claiming a universal latency gain on UMA hardware. `gpu_only` +remains an explicit failure until all PP-OCRv6 operators are device-resident. + +The expanded five-size memory soak (`16x16`, English, low-contrast, +`3000x80`, dense `1920x1080`) was also run twice per model. It showed no +unbounded retained activation frontier: tiny ended **14.63 MiB below** its +146,534,400-byte warm baseline; small and medium ended **8.66 MiB** and +**11.69 MiB** above their 178,892,800-byte and 425,119,744-byte baselines. +Those modest Windows allocator deltas are reported rather than hidden; a +future allocator-pool change must improve this measured dense-page result +without weakening the 24-case text-parity gate. + +### 2026-08-12: dense recognizer GEMM tile admission refinement + +The medium dense-page operator profile identified transformer dense projection +as the largest recurring recognizer cost (`FusedMatMulBias` was **28.685 ms** +for one profiled crop batch), ahead of any scalar postprocessing. The AVX-512 +four-row GEMM micro-kernel therefore now requires both `K >= 384` **and** +`N >= 384`. This keeps it on the PP-OCRv6 medium MLP expansion +`192x768` while retaining the lower-register-pressure two-row implementation +for the paired `768x192` projection. The runtime CPU hierarchy is unchanged: +AVX-512 is selected only after runtime CPUID/XCR0 checks, then AVX2/FMA, +then portable scalar/NEON. + +On the dense `1920x1080` medium UI (122 boxes, `rec_batch_size=4`, +`rec_parallelism=8`, eight kernel workers, one warm-up/three runs), the +refined default measured **4,328.474 ms**; disabling the four-row tile for +A/B gave **5,303.048 ms** (with a 6,549 ms shared-host tail). On `en.ppm`, +the same model measured **210.125 ms** versus **210.604 ms** disabled across +three warmups/ten runs. The normal AVX-512 kernel smoke, all three models' +eight-shape ONNX Runtime decoded-text gates (**24/24**), the Radeon 780M +Vulkan batch smoke, and a varied-shape hybrid batch identity check all passed. +The hybrid check continues to admit Vulkan only after complete-boundary +validation; in this sample it selected affine+Swish and depthwise variants +where GPU was faster, while keeping transfer-bound work on CPU. + +### 2026-08-12: GPU-aware NCHW batch benchmark controls + +`ppocr_batch_smoke` now supports repeatable steady-state measurements through +`PPOCR_BATCH_WARMUP` and `PPOCR_BATCH_RUNS`. It still verifies that every +batched page result (text, confidence, axis-aligned box, and four-point box) +matches serial inference exactly, then reports mean and median serial/batch +times. This exercises the existing real `[N,3,H,W]` detector batches and +cross-page recognizer crop batches; it is not a scheduler-only benchmark. + +On the local Radeon 780M / AVX-512 host, four identical `en.ppm` tiny pages +with `det_batch_size=4`, `rec_batch_size=4`, one outer worker, two warm-ups, +and five timed runs produced eight serial-identical results. CPU measured +**192.813 / 137.304 ms** serial/batched (**1.404x**); hybrid measured +**175.306 / 125.126 ms** (**1.401x**). The hybrid result remains governed by +per-shape full H2D + dispatch + fence + D2H validation, so a GPU segment is +used only when it measured no slower than SIMD CPU for that exact batch shape. + +The same hybrid configuration, with two warm-ups and three timed runs, gave +small **330.788 / 308.714 ms** (**1.072x**) and medium **991.291 / 1061.823 +ms** (**0.934x**) serial/batched. The medium result is intentionally retained: +on this shared UMA host, combining page/crop work can lose to cache pressure +and transfer-bound segments. Batch support therefore does not claim a +universal GPU gain, and `gpu_only` remains unavailable until the full graph is +device-resident. + +The latest run also reconfirmed dynamic high-ISA dispatch. With 12 kernel +workers and three warm-ups/six `en.ppm` runs, shape-gated AVX-512 pointwise +eight-output tiling measured tiny/small/medium **35.979 / 76.015 / 252.816 +ms**. Disabling only that tile via `PPOCR_DISABLE_AVX512_POINTWISE8=1` +measured **36.286 / 81.219 / 268.576 ms**. The tile remains limited to +`C_in >= 192`, `C_out >= 192`, and plane >= 256; AVX-512 selection is runtime +CPUID/XCR0-gated, followed by AVX2 and portable scalar/NEON fallbacks. + +### 2026-08-12: repeatable batch, Vulkan, memory, and model-size regression + +This pass kept the production CTC executor's terminal-logit memory mode +opt-in (`PPOCR_ENABLE_FUSED_TERMINAL_CTC=1`): it replaces a full terminal +`[N,T,V]` logits activation with a per-sequence row workspace, but remains +off by default because the regular SIMD GEMM path is faster on this host. +This preserves the lower peak-memory option without making an unmeasured +throughput trade-off the default. + +The complete CPU-side five-size private-memory soak was rerun with 12 kernel +workers over `16x16`, English, low-contrast, ultra-wide `3000x80`, and dense +`1920x1080` inputs. After all shapes were warmed, tiny finished cycle two +**10.09 MiB below** its **126,599,168-byte** baseline. Small and medium one +post-warm cycles reported **+4.07 MiB** from **178,348,032 bytes** and +**+10.47 MiB** from **425,025,536 bytes** respectively. These allocator +deltas are reported as observed rather than treated as a leak verdict. + +The decoded-text ONNX Runtime regression passed the full eight-shape corpus +for tiny and small (**8/8 each**), and the cross-model boundary subset +(`16x16`, English, low-contrast, `3000x80`) passed medium (**4/4**). The +Radeon 780M Vulkan primitive suite also passed numerical validation. In its +latest sample hybrid admitted affine+Swish (**0.18734 vs 0.37020 ms** GPU/CPU), +depthwise+Swish (**0.33626 vs 0.61096 ms**), and depthwise+HardSwish +(**0.31810 vs 0.34620 ms**); transfer-bound projection, GEMM, ordinary Conv, +and resize work stayed on CPU automatically. + +Finally, a paired six-run medium English benchmark with two warm-ups and 12 +kernel workers measured pure C++ CPU **259.037 ms** versus ONNX Runtime CPU +**297.913 ms** (**13.1% lower latency**, **3.860 vs 3.357 FPS**). The ORT +sample had shared-host variation, so this is a current reproducible snapshot, +not a universal multiplier. + +### 2026-08-12: optional large-map SIMD GELU admission + +`PPOCR_APPROX_GELU=1` now applies the PP-OCR-specific vector GELU +approximation only to tensors with at least 65,536 values. This avoids the +short, decode-sensitive boundary activations while allowing the AVX-512/AVX2 +path to amortize its approximation on genuine large feature maps. Exact +Erf-GELU remains the default, and Arm/NEON remains on the portable exact path. + +With 12 kernel workers, three warm-ups, and ten English-page runs, the gated +opt-in mode measured tiny/small/medium **27.295 / 53.594 / 204.034 ms**, +versus exact-default **28.491 / 61.181 / 214.164 ms** in the paired session: +**4.2% / 12.4% / 4.7%** lower latency. The opt-in decoded-text gate passed +tiny **8/8**, small **8/8**, and medium **4/4** across the same diverse +dimensions used above. A mixed-size hybrid page/crop batch also remained +serial-identical (four pages, seven results); it measured **161.524 / +164.530 ms** serial/batched on this heterogeneous mix, so no universal batch +speedup is claimed for unlike page shapes. + +### 2026-08-12: Vulkan batch revalidation + +After rebuilding the Vulkan batch path, the Radeon 780M primitive smoke test +again passed numerical validation. The complete-boundary policy kept the +transfer-bound binary, pointwise, depthwise, GEMM, ordinary-convolution and +resize probes on CPU; affine+Swish was the only selected GPU primitive in the +latest pass (**0.42584 vs 0.43290 ms** GPU/CPU). These are per-primitive +measurements including H2D, dispatch, fence and D2H, not a claim that the +whole OCR graph is GPU-resident. + +On four same-shape `en.ppm` pages with hybrid selected, one page worker, +`det_batch_size=4`, `rec_batch_size=4`, one warm-up and three timed runs, +the serial/batched comparison was **148.272 / 115.169 ms** (**1.287x**). +The result check remained exact at the public OCR result level (text, box and +confidence). The scheduler sends the real `N=4` tensor to both the CPU SIMD +and Vulkan primitive batch dimensions; heterogeneous inputs remain governed +by the existing width/shape buckets instead of being padded arbitrarily. + +### 2026-08-12: GPU batch-path cleanup and recheck + +The unvalidated experimental pointwise-to-depthwise Vulkan chain was removed. +It had never been reachable from the hybrid executor and had previously failed +its numerical validation, so retaining it would have overstated device-resident +graph support. The production Vulkan shader now contains only smoke-tested +primitive modes. `gpu_only` therefore continues to reject execution explicitly; +the implementation must not silently fall back to CPU until the complete +PP-OCRv6 graph, DB post-processing, and CTC decode can remain on the device. + +After the cleanup, the Radeon 780M Vulkan primitive smoke and AVX-512 kernel +smoke both passed. The same four-page tiny English batch (`det_batch_size=4`, +`rec_batch_size=4`, one outer worker, one warm-up, three timed runs) remained +serial-identical: CPU was **140.573 / 100.661 ms** serial/batched (**1.396x**), +and hybrid was **135.904 / 99.425 ms** (**1.367x**). A hybrid ONNX Runtime +text gate also passed **4/4** diverse tiny inputs (16x16, English, +low-contrast, and 3000x80 ultra-wide). These figures exercise the public +real-N detector and recognition batches; they do not claim a complete +GPU-resident inference path. + +### 2026-08-12: fused approximate BatchNorm-GELU + +When the existing opt-in `PPOCR_APPROX_GELU=1` mode is enabled, a large +fused BatchNorm-GELU group now performs its channel affine and AVX-512/AVX2 +Pad鑼?GELU approximation in one vector pass. This removes the previous +per-plane affine write/read round trip. The normal exact-Erf path is unchanged; +non-x86/NEON builds also retain its exact behavior. Set +`PPOCR_DISABLE_FUSED_BN_GELU=1` only to reproduce the former two-pass +experimental implementation for A/B measurement. + +On the local AVX-512 host with 12 worker threads, two warm-ups and six English +runs, the fused mode measured tiny **27.106 ms**, small **51.901 ms**, and +medium **225.597 ms**. The former two-pass opt-in path measured **27.241 / +62.450 / 232.207 ms** respectively, a material small-model reduction and a +positive medium improvement in that paired session. Decoded-text regression +against ONNX Runtime passed the eight-size corpus for tiny, small, and medium +(**24/24** total): 16x16, English, low-contrast, ultra-wide, English/CJK +single-line, mixed text, and CJK. The broad requirement to outperform ONNX +Runtime on every model and workload remains a continuing target, not a claim +from this one host-local optimization sample. + +### 2026-08-12: batch-invariant GELU admission correction + +The optional SIMD GELU admission was tightened so batching cannot change a +page's numerical execution path. Generic GELU is now always exact, because it +has no NCHW shape information and a total-element threshold could make a +singleton crop use Erf while the same crop in a batch used the approximation. +The model-aware fused BatchNorm+GELU path continues to use its AVX-512/AVX2 +one-pass approximation only when each NCHW plane is at least 65,536 elements; +this predicate is invariant to the leading batch dimension. Exact GELU remains +the default and ARM/NEON retains the exact fallback. + +After the correction, kernel and Radeon 780M Vulkan smoke both passed. The +hybrid decoded-text ONNX Runtime gate passed **4/4** tiny diverse inputs +(16x16, English, low contrast, and 3000x80), with `PPOCR_APPROX_GELU=1`. +The public four-page `en.ppm` batch gate also restored exact serial/batch +results at `det_batch_size=4`, `rec_batch_size=4`, and one recognition worker: +**169.174 / 123.454 ms (1.370x)** for its three-run hybrid sample. A longer +ten-run local snapshot measured CPU **165.446 / 118.013 ms (1.402x)** and +hybrid **210.649 / 142.646 ms (1.477x)**. These shared-host figures are batch +throughput evidence, not an end-to-end GPU-only performance claim; hybrid +still admits only individually validated full-boundary Vulkan segments. + +### 2026-08-12: MatMul write-only activation allocation + +The constant-weight transformer MatMul path now allocates its destination with +`resize()` rather than value-initializing it to zero. `kernels::Gemm()` writes +every output element from its bias/zero accumulator, so the previous clear was +dead memory traffic before the SIMD or Vulkan attempt. This reduces activation +write bandwidth and allocator work for the recognizer's tall batch-folded +projections without changing the CPU, hybrid, or ARM/NEON fallback semantics. + +Post-change kernel and Vulkan smoke passed, including the Radeon 780M +full-boundary admission checks. Hybrid decoded-text parity against ONNX Runtime +passed the eight-size corpus for every supported model (**24/24**): 16x16, +normal English, low contrast, 3000x80, English/CJK lines, mixed text, and CJK. +A separate eight-image mixed-aspect tiny hybrid batch check returned all 14 +serial-identical OCR results at **264.126 / 256.614 ms (1.029x)**; this is a +diversity/correctness gate and is intentionally not represented as a universal +throughput claim. + +For a current 12-worker, three-warmup/twenty-run `en.ppm` CPU comparison on +this shared host, the measured C++ / ONNX Runtime means were tiny **34.049 / +85.073 ms** (60.0% lower C++ latency), small **75.880 / 106.510 ms** (28.8% +lower), and medium **249.121 / 210.750 ms** (18.2% higher). The medium sample +does not satisfy the project performance target and is recorded explicitly: +the remaining work is medium recognizer/detector optimization and longer +device-resident Vulkan segments, not a claim that this pass has already made +all models faster than ONNX Runtime. + +### 2026-08-12: multi-adapter Vulkan selection for batched hybrid execution + +The Vulkan backend now evaluates all compute-capable adapters instead of +blindly selecting Vulkan's first enumerated queue. Its default selection is +the integrated/UMA adapter, which is the appropriate default for the current +per-segment H2D/dispatch/D2H hybrid design; set +`PPOCR_VULKAN_PREFER_DISCRETE=1` to prefer a discrete accelerator. Deployment +integration can pin an adapter with `PPOCR_VULKAN_DEVICE_INDEX=N` or select it +by substring through `PPOCR_VULKAN_DEVICE_NAME=...`. CPU Vulkan drivers are +not chosen automatically, but may still be requested by index for diagnostic +purposes. Every selected operator remains gated by its exact shape/batch, +full-boundary no-slower-than-CPU measurement. + +After this change, the Radeon 780M Vulkan smoke suite and AVX-512 kernel smoke +both passed. A four-page same-shape tiny batch (`det_batch_size=4`, +`rec_batch_size=4`, hybrid, one page worker, two warmups/five timed runs) +returned all eight public OCR results identically. The shared Windows host +showed unstable timing in the immediate post-build sample (**170.452 ms serial +/ 219.688 ms batch; batch median 119.245 ms**), so no new throughput claim is +made from that run. It nevertheless validates real `[N,3,H,W]` detector and +crop batches on the selected GPU path; it does not represent a GPU-only claim +because the complete graph, DB post-processing, and CTC decode are still not +device-resident. + +### 2026-08-12: GPU batch front-end parallelism + +The public batched API now exposes `Options::batch_preprocess_parallelism` +(default **4**), with the benchmark override +`PPOCR_BATCH_PREPROCESS_PARALLELISM`. For a same-shape detector batch, each +page's resize/BGR-normalize write owns a separate contiguous NCHW plane and is +prepared concurrently before the one batched CPU/Vulkan graph submission. +The budget is divided across concurrent dynamic-shape detector batches, so +raising `image_batch_parallelism` does not cause unbounded nested-thread +oversubscription. It is CPU front-end work that enables GPU/SIMD batching; it +does not change the strict Vulkan transfer/admission policy or imply a +GPU-only graph. + +On the local Radeon 780M / AVX-512 host with the tiny model, four identical +`en.ppm` pages, `det_batch_size=4`, `rec_batch_size=4`, one page worker, +`PPOCR_APPROX_GELU=1`, three warm-ups, and ten timed hybrid runs, the +serial-identical public result check passed in both configurations. Serial +preprocess (`PPOCR_BATCH_PREPROCESS_PARALLELISM=1`) measured **121.887 ms** +batched mean (**1.479x** against **180.328 ms** serial); the default four-way +front end measured **119.919 ms** (**1.498x** against **179.646 ms** serial). +This is a **1.6%** improvement in that controlled local batch sample. Timing +on the shared Windows host remains variable, so the README records it as a +reproducible configuration-specific result rather than a universal GPU gain. + +### 2026-08-12: experimental Vulkan tiled GEMM+Swish batch kernel + +The Vulkan shader now includes an 8-row x 128-column cooperative GEMM tile +with Swish fused into its final writeback (mode 25). It shares a 16x128 weight +tile across eight flattened recognition rows, so it is designed for real +same-width crop batches rather than per-crop dispatches. Its FP32 K reduction +remains ascending, and the shader stays behind the existing numerical smoke +and complete H2D + dispatch + fence + D2H admission checks. Enable it only for +driver-specific A/B work with `PPOCR_ENABLE_VULKAN_GEMM_SWISH_TILE=1`; the +plain tiled GEMM path remains dynamically selected as before. + +On the local Radeon 780M, AVX-512 host, the experimental tile passed kernel +and Vulkan primitive smoke plus the hybrid ONNX Runtime decoded-text gates for +tiny and medium (4/4 diverse inputs each). A quick medium four-page A/B saw +the tile at **1004.444 ms** batched mean and the default at **1041.713 ms**; +the longer shared-host samples varied enough that neither result is promoted +to the default. The default public medium batch remained result-identical and +measured **1178.757 / 1061.702 ms** serial/batched (**1.110x**) with two +warm-ups and six timed runs. This is an implementation and correctness +milestone, not a claim of a universal GPU speedup; hybrid continues to select +GPU only for primitives that win their exact full-boundary admission +measurement. + +### 2026-08-12: recognition-batch front-end parallelism + +`batch_preprocess_parallelism` now also prepares same-width recognition crops +in parallel. Each resize owns one already-zeroed, contiguous `[N,3,48,W]` +plane; output order, natural resize width, right padding, and normalization +arithmetic are unchanged. The front-end budget is divided by concurrent +recognizer batches, avoiding nested oversubscription when +`rec_parallelism > 1`. + +On the local Radeon 780M / AVX-512 host, four same-shape tiny English pages +with hybrid mode, `det_batch_size=4`, `rec_batch_size=4`, one recognizer +worker, two warm-ups and eight timed runs were public-result identical. A +serial front end measured **112.023 ms** batch mean; four-way front-end work +measured **105.894 ms**, a **5.5%** batch-latency reduction. The corresponding +serial/batch speedups were **1.523x / 1.577x**. A five-run small-model check +remained result-identical too (**314.876 / 313.329 ms** batch at one/four-way +preprocess); it is kept as evidence that the gain is input/model dependent, +not as a universal throughput claim. Kernel and Vulkan primitive smoke passed +after the change; decoded-text ONNX Runtime checks also passed the small +model's 16x16, English, low-contrast and ultra-wide inputs. Very dense/tall +synthetic pages remain a deliberately stricter diagnostic corpus: their +near-threshold DB boxes can differ from ORT by one pixel and therefore must +not be used as a text-parity gate without a geometric tolerance. + +### 2026-08-12: GPU-ready single-page crop batching + +The same crop-plane parallelism is now used by both public entry points: +`RecognizeBatch()` and ordinary `Recognize()`. A dense single page can contain +several same-width recognition crops, so this closes a scheduling gap where +only multi-page batches could prepare their real `[N,3,48,W]` input planes in +parallel. The budget is `Options::batch_preprocess_parallelism` (or +`PPOCR_BATCH_PREPROCESS_PARALLELISM`) and is divided by active recognizer +batches, which prevents nested CPU oversubscription. Each worker owns a +pre-zeroed NCHW plane; width padding and every pixel/normalization calculation +remain unchanged. + +This benefits the existing CPU SIMD and Vulkan hybrid paths equally. Vulkan +continues to receive a genuine NCHW batch, with its batch dimension mapped to +the shader dispatch Y dimension. It still offloads only an operator after its +same-shape, full H2D + dispatch + fence + D2H numerical/performance admission +test is no slower than the CPU kernel; `gpu_only` remains unavailable because +the complete PP-OCRv6 graph, DB postprocessing, and CTC decode are not +device-resident. + +Post-change verification passed the AVX-512 kernel smoke, Vulkan primitive +smoke, four-page public result identity, and a medium varied-shape hybrid +memory soak. On the local Radeon 780M / AVX-512 host, four equal `en.ppm` +tiny pages in hybrid mode (`det_batch_size=4`, `rec_batch_size=4`, one page +and recognizer worker, two warm-ups, six timed runs) measured **117.702 ms** +with serial front-end work and **110.992 ms** with a four-way front end: a +**5.7%** batch-latency improvement (serial/batch speedup **1.420x -> +1.498x**). A short medium CPU batch check also preserved all eight public OCR +results and measured **1118.404 / 1021.506 ms** serial/batched (**1.095x**). +These shared-host figures are configuration-specific benchmarks, not a claim +that every model or GPU segment is faster. + +### 2026-08-12: experimental AVX-512 wide-context tile + +Medium PP-OCRv6 detector context blocks include padded 5x5 and 7x7 +convolutions. An experimental AVX-512 eight-output tile now shares each +16-float input load across eight output channels, while keeping the existing +four-output implementation for a non-multiple-of-eight tail. It preserves +each output's increasing input/channel/kernel FMA order and has no effect on +AVX2, ARM/NEON, or scalar dispatch. Enable it only for deployment A/B work +with `PPOCR_ENABLE_AVX512_CONV_WIDE8=1`; the established four-channel tile +remains the default until it wins reliably across target CPUs. + +Both default and opt-in paths passed the kernel smoke, including padded 5x5 +and 7x7 eight-channel bodies plus nine-channel tails, and the full Radeon +780M Vulkan primitive suite. On this shared AVX-512 host, a medium `en.ppm` +CPU sample (two warm-ups/eight runs, twelve workers) measured **223.342 ms** +default and **221.962 ms** opt-in (0.6% lower mean). A 122-crop +`ui_dense_1920x1080` sample did not reproduce that gain (**4053.814 vs +4075.517 ms**, two warm-ups/five runs), so this remains deliberately opt-in +rather than a broad performance claim. Hybrid Vulkan admission remains +unchanged: every GPU primitive is still selected only when its validated full +H2D + dispatch + fence + D2H boundary is no slower than CPU. + +The same post-change CPU 12-worker `en.ppm` snapshot (two warm-ups/ten runs) +was tiny **36.902 ms**, small **72.035 ms**, and medium **272.094 ms**. +Hybrid runs (two warm-ups/six runs) were **37.502**, **72.662**, and +**255.454 ms** respectively. The medium hybrid improvement is useful on this +UMA GPU, while CPU remains slightly better for tiny/small in this run; the +per-primitive admission rule intentionally preserves that outcome instead of +forcing Vulkan. Medium decoded-text parity against ONNX Runtime also remained +**4/4** across 16x16, English, low-contrast, and 3000x80 inputs with the +experimental wide tile enabled. These measurements do not change the prior, +more representative ONNX Runtime comparison: medium has not yet demonstrated +a consistent end-to-end lead over ORT and remains the main optimization target. + +### 2026-08-12: fused GPU ordinary-Conv activation batches + +The hybrid Vulkan ordinary NCHW convolution primitive now also accepts +graph-fused **Swish**, Sigmoid, and HardSwish writebacks. Non-pointwise +detector/recognizer Conv activation chains therefore use one batched GPU +submission, with no GPU-to-CPU readback merely to apply the nonlinear pass. +The CPU SIMD fallback is unchanged. Admission remains exact per +`(N,C,M,H,W,kernel,stride,padding,activation)` and includes H2D, dispatch, +fence, D2H, and output validation against CPU Conv plus the same activation. +If this complete boundary loses, hybrid keeps CPU; `gpu_only` remains +unavailable. + +`ppocr_vulkan_smoke` now prints an independent `Conv+Swish` batch admission +measurement next to its existing `Conv+ReLU` result. This is primitive-level +evidence only; an end-to-end OCR GPU claim requires the corresponding shapes +to pass their dynamic admission measurements. + +Post-change AVX-512 kernel smoke and Radeon 780M Vulkan smoke both passed. +The new ordinary `N=4,C=24,M=40,31x29,3x3` Swish probe measured **3.58512 ms +GPU vs 1.24636 ms CPU**, so hybrid correctly retained CPU for that segment on +this UMA device. A hybrid four-page exact-shape batch regression also remained +result-identical: tiny measured **109.844 / 84.810 ms** serial/batched +(**1.295x**), and medium **920.012 / 836.339 ms** (**1.100x**) with two +warm-ups and three timed runs, `det_batch_size=4`, `rec_batch_size=4`, and +four-way preprocessing. Medium decoded-text ONNX Runtime parity passed **4/4** +for 16x16, English, low-contrast, and ultra-wide inputs. These are controlled +batch measurements on a shared host, not a GPU-only or universal throughput +claim. + +### 2026-08-12: liveness-aware in-place Concat + +Both graph executors now reuse the first dynamic input of a final-use ONNX +`Concat` as the output storage. The general implementation handles every +legal axis: after growing the vector, it moves the first input's outer blocks +backwards (overlap-safe) and copies only the additional branch spans. This is +especially relevant to the medium detector's channel-axis FPN assembly, where +operator profiling previously exposed `Concat` as a measurable cost. It avoids +one complete output allocation and the copy of the first branch while keeping +the generic path for shared/aliased/non-final-use inputs. `RunCtcTop1()` has +the same rule, so public recognizer batches do not diverge from `Run()`. + +Verification after the change passed AVX-512 kernel smoke, Radeon 780M Vulkan +smoke, and medium CPU decoded-text ONNX Runtime parity on 16x16, English, +low-contrast, and 3000x80 inputs (**4/4**). A medium hybrid seven-size memory +soak (16x16, English, low contrast, ultra-wide, ultra-tall, dense 1920x1080, +and 2560x1440 screenshot) finished one cycle at **+14,647,296 bytes** over a +453,398,528-byte post-warmup private-byte baseline. This is allocator +high-water behavior, not a leak assertion. The immediate six-run medium +`en.ppm` CPU sample measured **234.826 ms**; hybrid measured **258.733 ms** on +this shared UMA host, so the dynamic per-segment rule correctly does not claim +a blanket GPU gain. + +### 2026-08-12: hybrid GPU batching and queue-aware scheduling + +The Vulkan path continues to accept true detector and recognition NCHW +batches, and every implemented primitive uses the leading `N` dimension as +one dispatch dimension. This includes pointwise/residual, depthwise and +ordinary Conv, ConvTranspose, resize+Add, channel-affine, binary chains, and +recognizer GEMM. Immutable model weights/biases remain in the persistent +Vulkan context when an admitted segment repeats; dynamic images and residuals +are uploaded once per complete batch. The runtime restores compact descriptor +views before every dispatch, preventing a preceding cached parameter shape +from affecting a later batched operator. + +Hybrid execution has one synchronized Vulkan queue, so parallel host graph +batches cannot run device work concurrently. `Options::hybrid_graph_parallelism` +therefore defaults to **1** (benchmark override +`PPOCR_HYBRID_GRAPH_PARALLELISM`), avoiding serialized submissions together +with multiplied CPU activation workspaces. CPU-only keeps +`rec_parallelism` independent batches in flight. This is a scheduling and +memory-peak safeguard, not a restriction on the tensor batch itself; use a +positive override only after measuring the target driver. + +After the change, the AVX-512 kernel smoke and Radeon 780M Vulkan primitive +smoke both passed. On four same-shape tiny `en.ppm` pages with hybrid mode, +`det_batch_size=4`, `rec_batch_size=4`, four-way preprocessing, one warm-up, +and three timed runs, public OCR results were serial-identical. The queue-aware +default measured **150.969 / 105.663 ms** serial/batched (**1.429x**). An +explicit four-graph-worker A/B measured **131.838 / 102.749 ms** (**1.283x**) +on the same shared host. CPU-only under the same batch settings measured +**133.062 / 98.406 ms** (**1.352x**). These short, shared-host snapshots +demonstrate correct batch scheduling; they do not alter the strict +per-primitive GPU admission policy, do not claim universal GPU speedups, and +do not make `gpu_only` available. + +### 2026-08-12: refreshed three-model and varied-size baseline + +`ppocr_mem_soak` now accepts the same backend and bounded-batch environment +settings as the benchmark (`PPOCR_BACKEND`, detector/recognition batch sizes, +preprocessing, and hybrid graph parallelism). This makes the memory check +cover the production CPU/hybrid scheduler rather than always constructing a +default OCR instance. + +With `PPOCR_APPROX_GELU=1`, CPU mode, two warm-ups and eight timed `en.ppm` +runs on this AVX-512 host, current C++ means were tiny **28.602 ms**, small +**58.717 ms**, and medium **206.668 ms**. Hybrid on the same short workload +measured **32.243 / 70.071 / 259.296 ms** respectively, so CPU was correctly +retained for this particular small-map run when Vulkan segment admission did +not improve the full OCR boundary. The earlier representative ORT comparison +still establishes a lead for tiny/small; medium remains an active optimization +target and is not claimed universally ahead of ONNX Runtime. + +A medium hybrid varied-size one-cycle soak with seven samples (16x16, +English, low-contrast, ultra-wide, ultra-tall, dense 1920x1080, and +2560x1440 screenshot), `det_batch_size=4`, `rec_batch_size=4`, and four-way +preprocessing finished at **+2,134,016 bytes** over a +**436,551,680-byte** post-warmup private-byte baseline. This is a process +allocator high-water snapshot, not a leak proof; it demonstrates the current +test corpus and bounded activation behavior across materially different input +dimensions. + +### 2026-08-12: queue-aware detector batching + +`RecognizeBatch()` now applies the same queue-aware graph scheduling rule to +the detector as it already applied to recognition. `image_batch_parallelism` +still controls independent detector graphs in CPU mode. In hybrid mode, the +default is instead `hybrid_graph_parallelism=1`: one persistent synchronous +Vulkan queue cannot execute competing detector graphs concurrently, and +running several of them only retains several large detector activation +frontiers while their GPU submissions serialize. This does not reduce the +real tensor batch: same-resize pages still form bounded `[N,3,H,W]` detector +batches and all implemented Vulkan kernels map that N dimension to one +dispatch. Set `PPOCR_HYBRID_GRAPH_PARALLELISM` above one only after a +driver-specific A/B measurement. + +Post-change AVX-512 kernel and Radeon 780M Vulkan primitive smoke both +passed. Four identical `en.ppm` pages, `det_batch_size=4`, +`rec_batch_size=4`, four-way preprocessing, two warm-ups and five timed runs +were serial-result-identical. With the hybrid default, tiny measured +**147.010 / 107.388 ms** serial/batched (**1.369x**) and medium measured +**1050.363 / 1026.150 ms** (**1.024x**). The matching CPU-only measurements +were **136.004 / 105.275 ms** (**1.292x**) for tiny and **994.335 / 976.100 +ms** (**1.019x**) for medium. An explicit hybrid four-graph-worker experiment +was not a win in this sample: tiny batched latency rose to **158.929 ms**; +medium rose to **1096.940 ms**. A four-image varied-size medium hybrid smoke +also stayed serial-result-identical at **1242.143 / 1205.323 ms** (**1.031x**). +These shared-host measurements validate the scheduler and batch correctness; +they do not claim a universal GPU advantage. `gpu_only` remains unavailable +until the full PP-OCRv6 graph and post-processing are device-resident. + +### 2026-08-12: medium CPU parallelism retune + +The persistent CPU kernel executor's automatic ceiling is now **16** workers +(bounded by available hardware); `PPOCR_BENCH_THREADS` remains the explicit +deployment override. The previous automatic ceiling of 12 left measurable +medium-detector channel/tile parallelism unused on this AVX-512 host. Tiny and +small keep their short-kernel thresholds, so this is not a promise that every +model launches sixteen workers. + +On the local AVX-512 host with `PPOCR_APPROX_GELU=1`, two warm-ups and twelve +timed `en.ppm` runs, the default CPU path measured tiny **28.124 ms**, small +**61.297 ms**, and medium **188.145 ms**. A medium 3000x80 strip measured +**130.692 ms** over eight runs. The controlled medium A/B was 12 workers: +**215.234 ms** mean, 16 workers: **189.517 ms** mean (both twelve-run +samples); 20 and 24 workers regressed, so the automatic cap is deliberately +16 rather than unbounded. The current same-host ORT eight-run `en.ppm` +snapshot is tiny **74.609 ms**, small **86.288 ms**, and medium **147.779 +ms**: tiny/small retain clear native wins, while medium remains slower than +ORT on that comparison and is not claimed as meeting the final target. + +The latest Radeon 780M Vulkan primitive suite still passed. Its full-boundary +admission selected GPU for the Swish channel-affine and depthwise-Swish batch +shapes, while ordinary Conv, pointwise Conv, GEMM and resize/add samples +remained transfer-bound and correctly retained CPU. A medium hybrid `en.ppm` +sample was **295.677 ms** (eight runs), versus the CPU result above, confirming +that a device-resident multi-operator graph segment閳ユ攺ot forced standalone +dispatches閳ユ攰s required before claiming a medium GPU end-to-end win. + +### 2026-08-12: N=8 GPU-aware page batch and PPM stress gate + +The public batch route was rechecked with eight identical tiny `en.ppm` +pages. It forms an exact `[8,3,H,W]` detector tensor and packs compatible +recognition crops into `[N,3,48,W]`; no page or crop is resampled merely to +fill a batch. Vulkan maps that leading N dimension to one compute-dispatch +dimension for each implemented hybrid primitive. With 16 CPU kernel workers, +`det_batch_size=8`, `rec_batch_size=8`, eight-way preprocessing, one graph +submitter, two warm-ups and eight timed runs, serial results and batch results +were exactly identical (16 decoded OCR results): + +| Backend | Serial mean | N=8 batch mean | Batch speedup | +|---|---:|---:|---:| +| CPU | 337.102 ms | 233.977 ms | 1.441x | +| Hybrid Vulkan | 454.287 ms | 239.397 ms | 1.898x | + +This is a same-host batch scheduling measurement, not a claim that the +partial Vulkan graph makes whole-image OCR faster than CPU on the Radeon 780M: +the hybrid N=8 mean was still 2.3% above the CPU N=8 mean. It does verify that +Vulkan-enabled batching is a real single-NCHW submission path with correct +output, rather than eight independent GPU calls. + +### 2026-08-13: front-end address reduction and expanded recovery check + +The fused RGB bilinear-resize/NCHW-normalization front end now hoists its two +source-row bases out of the destination-pixel loop. This removes four +row/column address multiply-add chains per output pixel, without changing the +four source samples, interpolation order, integer rounding, or model input. +It applies to both detector-page resize and recognizer-crop resize paths, so +the benefit is architecture-neutral and composes with the existing AVX2, +AVX-512, and NEON graph kernels. + +The change passed the complete low-level SIMD smoke suite and decoded-text +comparison with ONNX Runtime for all model sizes: tiny, small, and medium each +passed **4/4** inputs (`16x16`, English two-line, low-contrast text, and an +ultra-wide `3000x80` strip), for **12/12** total. The wider robustness corpus +also passed **11/11** cases for tiny and small: blank, word, rotated text, +low-contrast text, wide/tall strips, dense blobs, dense UI, and 1920x1080 / +2560x1440 screenshots. Medium passes the same semantic corpus except its +current detector threshold produces extra low-score components on the blank +and dense-blob synthetic cases; this is tracked as DB-postprocess tuning work, +not hidden as a performance success. + +A fresh exact `N=4` CPU batch recheck (`det_batch_size=4`, +`rec_batch_size=4`, four-way preprocessing, one warm-up, five timed runs) +kept all eight decoded outputs serial-identical. Mean batch speedups on this +shared AVX-512 Windows host were tiny **1.490x**, small **1.129x**, and medium +**1.243x**. The medium value has visibly variable shared-host samples, so +these figures are evidence of the batched code path rather than portable +capacity guarantees. + +The expanded `16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> 1280x720 +-> 1920x1080 -> 2560x1440 -> 64x64` memory ladder was rerun for medium. CPU +passed two cycles from a 146,903,040-byte warmed private baseline and returned +to 143,212,544 bytes (-2.51%) and 144,183,296 bytes (-1.85%); private bytes +and working set both declined after the largest image in both cycles. Hybrid +Vulkan also passed: its 392,998,912-byte baseline returned to 393,195,520 +bytes (+0.050%) in both cycles. Hybrid private bytes remained 0.0031% above +the immediately preceding largest sample while working set declined, which is +expected persistent Vulkan/Windows allocator capacity rather than retained +image or activation memory. + +### 2026-08-13: selective SIMD GELU dispatch + +The opt-in `PPOCR_APPROX_GELU=1` path now reaches independent generic +`FusedGelu` activations as well as the existing fused BatchNorm+GELU route. +On x86 it dynamically selects AVX-512 first, then AVX2; the baseline exact +Erf implementation and ARM/NEON fallback remain unchanged. The approximate +Pad鑼?tanh polynomial is intentionally limited to broad activations of at +least 262,144 elements. That preserves the established exact path for the +short, decision-sensitive tiny/small recognizer tensors while accelerating +the large medium feature maps. `PPOCR_DISABLE_APPROX_GELU_SIMD=1` is a direct +deployment A/B escape hatch. + +The AVX2 generic GELU kernel was also made genuinely vectorized: it no longer +stores each vector and calls scalar `tanh` eight times. AVX2 and AVX-512 now +use the same bounded Pad鑼?approximation for vector bodies and scalar tails. +The low-level smoke verifies separate and in-place large/tail GELU buffers, +and passed in both approximate and default exact modes. + +With 16 workers on the local AVX-512 host, a paired medium CPU `en.ppm` A/B +(two warm-ups, eight timed runs) improved from **216.867 ms** with the new +generic SIMD route disabled to **205.715 ms** enabled (**5.1% lower** mean +latency). Tiny, small and medium each again passed all four decoded-text +comparisons against ONNX Runtime (`16x16`, English, low contrast and +`3000x80`), **12/12** total. The same-host 12-run CPU snapshot after the +change was tiny **34.335 ms** and small **75.072 ms**; shared-host variance +means these are compatibility snapshots, not portable throughput guarantees. + +### 2026-08-13: SIMD terminal-CTC memory route + +`PPOCR_ENABLE_FUSED_TERMINAL_CTC=1` now computes each reusable terminal-logit +row through the normal runtime-dispatched GEMM kernel instead of a separate +scalar `K鑴砎` loop. It still avoids materializing the full terminal `[N,T,V]` +logits tensor, but now uses AVX-512, AVX2, or ARM/NEON GEMM as available and +uses the existing ISA argmax. The K-order, selected-class Softmax calculation, +blank/repeat CTC recurrence, and output confidence remain unchanged. + +With this opt-in mode and 16 CPU workers, all three models passed the four +diverse ONNX Runtime decoded-text inputs (**12/12**). The new N=4 public batch +smoke was serial-result-identical and measured **1.367x** (tiny), **1.149x** +(small), and **1.188x** (medium) batch speedup on this shared AVX-512 Windows +host. Two warm-ups/eight English-page runs measured **35.933 / 74.952 / +246.148 ms** for tiny/small/medium. The medium two-cycle +`16x16 閳?閳?閳?2560x1440 閳?64x64` CPU memory ladder also passed: a +**147,066,880-byte** warmed baseline returned to **143,347,712 bytes** +(-2.53%) and **147,116,032 bytes** (+0.03%), both below their pre-return +cycle high-water marks. The regular full-terminal-logits SIMD route remains +the default; this stays an explicit memory/performance deployment option. + +### 2026-08-13: four-row terminal-CTC GEMM tile + +The optional terminal-CTC route now projects up to four adjacent time steps +into its bounded vocabulary workspace at once, then performs the CTC scan in +the original time order. This keeps memory bounded to `4 鑴?vocab` values per +active sequence rather than `[N,T,V]`, while allowing the AVX-512/AVX2 GEMM +microkernels to reuse immutable projection weights across rows. The final +partial tile and every blank/repeat transition retain the same semantics. + +On the 16-worker AVX-512 host, two warm-ups/eight `en.ppm` runs with +`PPOCR_ENABLE_FUSED_TERMINAL_CTC=1` measured **32.647 / 70.079 / 226.250 ms** +for tiny/small/medium. Compared with the preceding one-row fused-CTC sample, +this is **9.1% / 6.5% / 8.1%** lower latency. The post-change N=4 CPU smoke +remained serial-result-identical for all models and measured **1.350x**, +**1.201x**, and **1.195x** batch speedup respectively. The low-level kernel +smoke, all three four-image ONNX Runtime decoded-text comparisons (**12/12**), +and Radeon 780M Vulkan primitive/admission smoke passed. As intended, hybrid +continues to select GPU only for shapes that win the full transfer boundary; +the terminal CTC tile is a CPU-memory optimization, not a GPU-only path. + +### 2026-08-13: four-row terminal-CTC resolution-ladder memory recheck + +The deterministic `16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> +1280x720 -> 1920x1080 -> 2560x1440 -> 64x64` ladder was rerun after the +four-row terminal-CTC tile, with `PPOCR_BENCH_THREADS=16`, +`PPOCR_APPROX_GELU=1`, and `PPOCR_ENABLE_FUSED_TERMINAL_CTC=1`. The CPU +medium model passed the two-cycle bounded-recovery gate. Its warmed private +baseline was **143,339,520 bytes**; the post-large `64x64` samples were +**148,660,224 bytes** (**+3.71%**) and **147,742,720 bytes** (**+3.07%**). +They were only **+0.68%** above the immediately preceding `2560x1440` +sample in each cycle, well below the 20% gate. + +In this particular shared-Windows-host run, neither private bytes nor working +set immediately declined after the largest page: the allocator retained or +reused capacity, rather than keeping the RGB image or activation objects +alive. The checker records this explicitly as `declined_after_largest=false` +and retains every per-resolution private-byte/working-set sample in +`build/memory_ladder_medium_fused_ctc_tile4_cpu_20260813.json`; it therefore +does not mislabel stable allocator capacity as immediate memory release. The +completed image is destroyed before every sample, and the bounded-recovery +pass is the portable regression condition. + +### 2026-08-13: AVX-512 reconstruction 2x2 four-output default + +The CPU dispatcher now enables the existing AVX-512 four-output tile for +valid `2x2` reconstruction convolutions by default when the shape has at +least eight input channels. It reuses each 16-float input vector across four +output filters while retaining the same per-output reduction order, scalar +tail, AVX2, NEON, and baseline fallbacks. This covers the tiny/small/medium +detector reconstruction pairs (`8閳?6`, `12閳?4`, and `32閳?4` channels) without +introducing an ISA requirement. Set `PPOCR_DISABLE_AVX512_CONV2X2_TILE4=1` +for a deployment A/B fallback. + +On the local shared AVX-512 Windows host (`PPOCR_BENCH_THREADS=16`, opt-in +approximate GELU and four-row terminal CTC), the medium English page improved +from **237.935 ms** to **230.035 ms** across 16 timed runs (**3.3% lower** +mean latency). A two-run dense `1920x1080` sample also reduced from +**4,740.695 ms** to **4,208.679 ms** (**11.2% lower**); this dense figure is +intentionally short and host-variable, so it is directional rather than a +portable throughput guarantee. A fresh 2-warmup/8-run CPU snapshot measured +tiny **35.970 ms**, small **79.078 ms**, and medium **235.396 ms** on `en.ppm`. + +All three models passed the four varied ONNX Runtime decoded-text cases +(**12/12**: `16x16`, English, low contrast, and `3000x80`) with the new +default. The N=4 public batch smoke stayed serial-result-identical and +measured **1.314x**, **1.210x**, and **1.087x** speedup for tiny, small, and +medium. The low-level exact/approximate SIMD smoke and the Radeon 780M Vulkan +admission smoke also passed. A current short hybrid sample was **35.627 / +84.529 / 294.957 ms** (tiny/small/medium), so the transfer-inclusive admission +rule continues to select Vulkan only for segments that actually meet the +no-slower condition; this does not claim complete GPU-only PP-OCRv6 support. + +### 2026-08-13: terminal-projection SIMD coverage expansion + +The dependency-free kernel smoke now includes the exact terminal projection +geometries of every shipped recognizer: `4x80x6906` for tiny and +`4x120x18710` / `4x192x18710` for small/medium, plus the bounded terminal-CTC +route. This explicitly exercises wide vocabulary tails, bias initialization, +the AVX-512 four-row GEMM reuse tile, and the unchanged scalar/AVX2/NEON +fallback contract rather than inferring coverage from a smaller synthetic +matrix. + +A renewed CPU A/B on the English page (three warm-ups, 12 runs, 16 workers, +exact terminal logits) measured tiny/small/medium at **28.508 / 62.702 / +192.242 ms** with the default reconstruction tile, versus **28.950 / 63.142 / +198.772 ms** with `PPOCR_DISABLE_AVX512_CONV2X2_TILE4=1` (**1.5% / 0.7% / +3.3% lower**). Separately disabling the already-default AVX-512 four-row +GEMM tile produced **30.019 / 63.584 / 196.993 ms**, confirming that its main +measured benefit is medium's wide transformer projections. These remain +shared-host snapshots, not cross-machine guarantees. + +### 2026-08-13: batched AVX-512 2x2 reconstruction tile + +`Conv2dBatch` now uses the same AVX-512 four-output `2x2` valid-convolution +tile as the single-image dispatcher. Its scheduler owns one +`[batch, output-channel-tile]` task instead of one output plane, preserving +the exact per-channel reduction order while reusing every loaded input vector +over four filters for detector batches. The existing AVX2, NEON, scalar, tail, +and `PPOCR_DISABLE_AVX512_CONV2X2_TILE4=1` fallback paths remain intact. + +With four equal English pages, `det_batch_size=4`, `rec_batch_size=4`, +four-way preprocessing, two warm-ups, and five timed runs, serial-vs-batch +results remained bit-identical. The tile-enabled batch means were **91.918 / +213.696 / 781.774 ms** for tiny/small/medium, versus **93.346 / 223.177 / +939.356 ms** with the tile disabled: **1.5% / 4.2% / 16.8% lower** batch +latency on this shared AVX-512 host. The corresponding complete +serial-to-batch speedups were **1.290x / 1.194x / 1.096x**. All three models +also passed their four-image ONNX Runtime decoded-text checks (**12/12**). + +### 2026-08-13: refreshed small-to-large memory ladder + +The native memory regression now exercises one live medium PP-OCRv6 instance +over a deterministic ascending image sequence: `16x16 -> 64x64 -> 160x120 -> +320x240 -> 640x480 -> 1280x720 -> 1920x1080 -> 2560x1440 -> 64x64`. Each +image is decoded, inferred, destroyed, and only then sampled. The report +therefore records process private bytes and Windows working-set bytes for +every resolution, plus whether the final small image returns below the +pre-large high-water mark and whether it immediately declines from the +preceding largest-image sample. + +A fresh CPU run with 16 workers and `PPOCR_APPROX_GELU=1` passed two cycles +from a **143,192,064-byte** warmed private baseline. The final `64x64` +samples were **148,197,376 bytes** (+3.50%) and **147,365,888 bytes** +(+2.91%); both were below the respective pre-return peaks of **149,053,440** +and **150,142,976 bytes**, and comfortably passed the 20% bounded-recovery +gate. In this particular shared-Windows-host measurement, neither final +sample immediately fell below its directly preceding `2560x1440` sample +(+1.67% / +1.76%), and working set showed the same allocator-capacity +retention. This is reported as `declined_after_largest=false`, not presented +as an immediate decommit: the completed large image and its inference +temporaries have already been destroyed before measurement. The durable +per-resolution report is +`build/memory_ladder_medium_cpu_tile4_20260813.json`. + +### 2026-08-13: tiny resolution-ladder recovery rerun + +The same native small-to-large-to-small memory gate was also run against the +tiny PP-OCRv6 model with 16 CPU workers and `PPOCR_APPROX_GELU=1`. It uses +the deterministic sequence `16x16 -> 64x64 -> 160x120 -> 320x240 -> +640x480 -> 1280x720 -> 1920x1080 -> 2560x1440 -> 64x64`, sampling only after +each decoded image and its inference temporaries have gone out of scope. + +Both cycles passed the 20% bounded-recovery gate from a **9,195,520-byte** +warmed private-byte baseline. Immediately after `2560x1440`, the final +`64x64` sample fell from **9,940,992** to **9,232,384 bytes** (**-7.13%**) in +cycle one, and from **10,711,040** to **9,330,688 bytes** (**-12.89%**) in +cycle two. Working set declined in both cycles as well. This directly +confirms recovery after the largest image on the current host; the durable +per-resolution report is `build/memory_ladder_tiny_cpu_latest.json`. + +### 2026-08-13: Vulkan terminal-GELU chain and immutable-chain cache + +The Vulkan MobileNet `depthwise -> pointwise` chain now has an optional mode +that applies the existing opt-in AVX2/AVX-512 GELU approximation in its final +GPU writeback. It avoids the former GPU readback followed by a full CPU GELU +pass for the medium-only graph fusion. This path is selected only when +`PPOCR_APPROX_GELU=1` and the CPU dispatcher would make that same approximate +choice for the same logical tensor size; exact ONNX Erf-GELU, ARM/NEON, and +small tensors keep their established CPU behavior. The chain also reuses its +immutable depthwise weights, bias, and packed pointwise parameters across +consecutive submissions, while invalidating that cache whenever a shared +Vulkan scratch binding is overwritten. + +The AMD Radeon 780M Vulkan smoke validates both regular and GELU-fused chain +outputs against the shared CPU kernels. Hybrid admission still measures the +complete upload, dispatch, fence, and readback boundary and only chooses GPU +when it is no slower; on this host the representative depthwise-pointwise +chain remained CPU-preferred (**0.601 ms GPU / 0.183 ms CPU**), while +affine+Swish and depthwise+Swish primitives were admitted in the same smoke. +This is intentional: the change makes a qualifying GPU segment cheaper +without relaxing the no-slower policy. + +With 16 workers and `PPOCR_APPROX_GELU=1`, decoded-text parity versus ONNX +Runtime passed all four diverse inputs for each official model (**12/12**): +`16x16`, English, low contrast, and `3000x80` ultra-wide text. The paired +eight-run `en.ppm` CPU/hybrid snapshots were tiny **32.042 / 34.855 ms**, +small **63.781 / 70.924 ms**, and medium **191.886 / 219.099 ms**. Thus this +UMA run correctly retains CPU for the complete models; it is not presented as +a blanket GPU speed claim. Reports are +`build/accuracy_{tiny,small,medium}_vulkan_gelu_fusion_20260813.json` and +`build/bench_{tiny,small,medium}_cpu_hybrid_gelu_fusion_20260813.json`. + +The two-cycle medium `16x16 -> ... -> 2560x1440 -> 64x64` CPU memory ladder +also passed from a **147,148,800-byte** warm baseline. Private bytes fell +immediately after the largest image in both cycles (**-2.01%** and **-1.39%**) +and working set fell as well; the durable report is +`build/memory_ladder_medium_cpu_vulkan_gelu_fusion_20260813.json`. + +### 2026-08-13: refreshed ascending-resolution memory measurement + +A fresh two-cycle medium CPU run (16 kernel workers, +`PPOCR_APPROX_GELU=1`) reconfirmed the deterministic +`16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> 1280x720 -> 1920x1080 +-> 2560x1440 -> 64x64` sequence. The checker samples process private bytes +and Windows working set only after each source image and its inference result +have left scope. It passed the 20% bounded-recovery gate from a +**143,245,312-byte** warmed private baseline. + +In cycle 1 the final `64x64` sample was **146,501,632 bytes** (+2.27% from +baseline, -0.63% from the pre-return private-byte peak); in cycle 2 it was +**143,319,040 bytes** (+0.05%, -4.66%). The returned small image was below +the pre-return private-byte and working-set peaks in both cycles. It was +**1.89%** above the immediately preceding `2560x1440` private-byte sample in +cycle 1, but **2.04%** below it in cycle 2; the working set follows the same +pattern. Therefore the report truthfully records +`declined_after_largest=false` for cycle 1 and `true` for cycle 2 instead of +claiming unconditional immediate decommit. This distinguishes bounded +live-memory recovery from Windows allocator capacity retention. Full +per-resolution evidence is in +`build/memory_ladder_medium_cpu_latest_20260813.json`. + +### 2026-08-13: SE-gate fusion investigation + +The detector's largest squeeze-excitation block (`ReduceMean -> 1x1 -> ReLU +-> 1x1 -> HardSigmoid -> channel Mul`) was profiled as a large-page memory and +traffic candidate. A strict graph fusion was added behind +`PPOCR_ENABLE_SE_GATE_FUSION=1`: it retains the dying NCHW source allocation, +forms only compact `[N,C,1,1]` gate storage, then scales the source in place. +It preserves the original per-channel FP32 reduction and gate order, and the +tiny/small/medium text regression passed **12/12** cases with it enabled. + +It is intentionally **not** a production default yet. On the current +16-worker AVX-512 host, the 30-run `en.ppm` A/B was favourable for tiny +(**30.926 -> 29.772 ms**, 1.039x), but regressed small (**61.034 -> 63.710 +ms**) and was neutral for medium (**205.271 -> 205.028 ms**). A three-run +medium `2560x1440` page A/B was also within noise but not a reliable win +(**2924.075 -> 2952.852 ms**). Retaining this as opt-in prevents a +memory-oriented fusion from silently violating the all-three-model latency +requirement; the exact gate pattern remains available for a future +device-resident Vulkan chain. + +After this investigation, a fresh medium two-cycle resolution ladder again +passed the 20% bounded-recovery gate. Its warmed private-byte baseline was +**143,261,696 bytes**. The final `64x64` sample fell below the immediately +preceding `2560x1440` sample in cycle 1 (**-1.70%**) and remained within the +gate in cycle 2 (**+2.13%**); working-set results and every resolution are in +`build/memory_ladder_medium_cpu_post_se_experiment_20260813.json`. + +### 2026-08-13: AVX-512 stride-two NCHW batch tile + +The AVX-512 `3x3, stride=2` NCHW batch scheduler now assigns one task to a +four-output-channel tile instead of invoking the kernel one channel at a +time. Its SIMD body therefore shares every gathered/packed source vector +across four filters, exactly as the single-image dispatcher already did. +Output-channel ownership remains disjoint and each output retains the same +ascending FP32 accumulation order. The optimization is dynamically entered +only after the existing AVX-512 runtime feature check; AVX2, scalar, and ARM +NEON paths are unchanged. Set +`PPOCR_DISABLE_AVX512_STRIDE2_BATCH_TILE4=1` for a deployment A/B fallback. + +The low-level kernel smoke and Vulkan smoke passed. Decoded-text comparison +against ONNX Runtime passed all four varied inputs (`16x16`, English, +low-contrast, `3000x80`) for tiny, small, and medium (**12/12**); reports are +`build/accuracy_{tiny,small,medium}_stride2_batch_tile4_20260813.json`. + +On four equal English pages, real detector and recognizer NCHW batches +(`det_batch=4`, `rec_batch=4`, exact width, two warm-ups, twelve timed runs) +remained serial-result-identical and measured these complete +serial-to-batch speedups on the 16-worker AVX-512 host: **1.573x** tiny +(184.036 / 116.981 ms), **1.379x** small (407.445 / 295.523 ms), and +**1.279x** medium (1105.502 / 864.359 ms). This exercises the new stride-two +batch route directly, rather than inferring a batch benefit from a single +page. Exact sample records are +`build/batch_{tiny,small,medium}_stride2_batch_tile4_20260813.txt`. + +The same refreshed eight-run single-English CPU/Hybrid check measured +CPU **33.938 / 71.164 / 206.282 ms** and Hybrid +**36.744 / 74.706 / 292.331 ms** for tiny/small/medium. On this UMA Radeon +780M host, Hybrid remains slower end-to-end, while individual admitted +Vulkan affine+Swish and depthwise+Swish segments still obey the +transfer-inclusive no-slower policy. The result is not presented as a +whole-model GPU speed claim. + +### 2026-08-13: heterogeneous-size batch regression + +`bench/heterogeneous_batch_regression.py` adds a repeatable multi-size page +batch gate around `ppocr_batch_smoke`. Its PPM corpus deliberately combines +`16x16`, ordinary two-line text, low-contrast text, `3000x80` wide text, +`80x3000` portrait text, a dense `1920x1080` UI page, and a `2560x1440` +screenshot. It executes both exact-width (`PPOCR_REC_WIDTH_BUCKET=1`) and +a candidate padded-width grouping, while `ppocr_batch_smoke` verifies every +batch result is identical to serial inference. The JSON records both timing +samples rather than promoting a padding policy from a narrow equal-page test. + +On the current 16-worker AVX-512 CPU with approximate GELU, all three models +passed serial-identity on this seven-image / 186--188-result corpus. The +exact-width batch means were **473.748 ms** (tiny), **1771.887 ms** (small), +and **8437.291 ms** (medium), with serial-to-batch speedups of **1.258x**, +**1.156x**, and **1.038x**, respectively. A 16-pixel candidate bucket +measured **487.901 ms** (+3.0%), **1796.819 ms** (+1.4%), and **8945.280 ms** +(+6.0%). Exact-width therefore remains the lower-memory CPU default; the +candidate remains an exposed deployment knob for workloads where reduced +shape fragmentation pays back its bounded right-padding. Reports are in +`build/heterogeneous_batch_{tiny,small,medium}_bucket16_20260813.json`. + +### 2026-08-13: batch-invariant GELU policy + +The selective GELU dispatch now receives the logical per-sample element count +from every generic and fused graph route. Consequently, packing four equal +pages/crops into an NCHW batch cannot change a short tensor from exact Erf to +the opt-in approximate formula merely because the batch has four times as many +elements. This closes a batch-correctness edge case while keeping the medium +large-map AVX-512/AVX2 acceleration. The low-level GELU smoke passed in both +exact and approximate configurations, and all three models again passed the +four-image ONNX Runtime decoded-text gate (**12/12**). + +An N=4 CPU public-batch smoke with `det_batch_size=4`, `rec_batch_size=4` and +four-way preprocessing remained serial-result-identical for every model. On +this shared AVX-512 host it measured tiny **1.346x**, small **1.090x**, and +medium **1.055x** serial-to-batch speedup. A new paired medium CPU A/B (two +warm-ups, eight runs) measured **211.217 ms** with the corrected SIMD route +and **219.778 ms** with `PPOCR_DISABLE_APPROX_GELU_SIMD=1` (**3.9%** lower +mean latency). Hybrid measured **314.123 ms** in the same short sample; the +strict transfer-inclusive Vulkan admission therefore remains necessary and +continues to retain CPU for transfer-bound operators. + +### 2026-08-13: Vulkan batch-admission parity correction + +The per-shape Vulkan admission probes for pointwise Conv and residual +pointwise Conv now benchmark the same batched CPU SIMD kernels used by live +`[N,C,H,W]` OCR execution. Previously these two probes used a serial loop of +single-image kernels even though the executor flattens batch/channel tiles; +that could make a GPU segment appear no slower than a weaker CPU reference. +The correction does not change model arithmetic or force a GPU path. It makes +the hybrid policy stricter and accurate: Vulkan is selected only when its full +upload, dispatch, synchronization, readback, and validation boundary is no +slower than the real batched CPU alternative. + +`ppocr_vulkan_smoke` and the full SIMD kernel smoke passed on the local AMD +Radeon 780M / AVX-512 host. The current primitive measurements correctly +retain CPU for pointwise Conv (`0.22340 ms` GPU versus `0.02218 ms` CPU) and +residual pointwise Conv+ReLU (`0.24984 ms` versus `0.03832 ms`), while keeping +GPU for the validated depthwise+Swish sample (`0.41966 ms` versus `0.42462 +ms`). This is explicit evidence of the requested no-slower hybrid policy, +not a claim of universal GPU speedup or GPU-only availability. + +### 2026-08-13: current three-model CPU/hybrid snapshot + +With `PPOCR_BENCH_THREADS=16` and `PPOCR_APPROX_GELU=1`, a refreshed CPU +measurement on the two-line English PPM used two warm-ups and twelve timed +runs. Tiny measured **33.025 ms** (30.280 FPS), small **70.530 ms** (14.178 +FPS), and medium **246.420 ms** (4.058 FPS). A controlled medium worker scan +on the same shared host measured 8 / 12 / 16 workers at **366.673 / 282.361 / +246.420 ms**, respectively; this validates the current 16-worker ceiling for +the broad medium graph without claiming that all deployments share that curve. + +Hybrid mode with the same model/input and two warm-ups/eight runs measured +tiny **37.400 ms**, small **75.953 ms**, and medium **235.987 ms**. Medium +therefore saw a **4.2%** lower mean latency on this local hybrid run, while +tiny/small correctly remain CPU-preferred at the segment level when transfers +do not pay back. A paired medium ONNX Runtime 1.28 CPUExecutionProvider run +(matching 16-thread budget, two warm-ups/eight runs) measured **399.188 ms**; +the native medium CPU snapshot is **38.3%** lower latency and hybrid is +**40.9%** lower on this host. These are shared-host measurements rather than +portable guarantees; model accuracy and the hybrid admission rule remain +independent of benchmark mode. + +`bench/stress_regression.py` now resolves a default `.png` case to a sibling +`.ppm` case when necessary. The checked-in native regression corpus can +therefore run directly without duplicating the large source images or adding +an image decoder to the C++ executable. The tiny-model CPU stress gate passed +all **11/11** cases: dense UI, blank, single word, ultra-wide/tall strips, +tiny, low-contrast, rotated, dense blobs, and two screenshot sizes. + +### 2026-08-13: Vulkan GELU-chain smoke repair and refreshed checks + +The Vulkan smoke's depthwise-to-pointwise mode 30 test now calculates the +same explicit Pad鑼?tanh GELU approximation as the shader. Previously the test +accidentally compared this opt-in approximation with exact `kernels::Gelu()` +when `PPOCR_APPROX_GELU` was unset, producing a false failure even though the +shader's mode was correct. This is a test-only correction: it does not change +the default exact-GELU execution policy or GPU admission rule. The rebuilt +AVX-512 kernel smoke and Radeon 780M Vulkan primitive suite passed, including +the device-resident depthwise閳姫ointwise閳墱ELU chain. + +The refreshed CPU-versus-ORT `en.ppm` comparison (16 kernel workers, opt-in +approximate GELU, 2 warm-ups/20 timed runs) measured native tiny **40.480 ms** +versus ORT **122.008 ms** (**66.8% lower latency**), small **79.199 ms** versus +**183.173 ms** (**56.8% lower**), and medium **242.245 ms** versus **291.551 +ms** (**16.9% lower**). These are local shared-host measurements, not a +portable guarantee. Decoded-text parity against ORT also passed four diverse +inputs for each model (English, mixed text, single-line text, and low-contrast +multi-line text): **12/12**. + +Hybrid retains the strict full-boundary admission rule and therefore only +uses a Vulkan segment when its measured H2D閳妿ispatch閳姁ence閳墬2H result is no +slower than the matching CPU SIMD work. A seven-image varied-size hybrid batch +(16x16, English, low contrast, ultra-wide, ultra-tall, 1920x1080 UI, and +2560x1440 screenshot) stayed serial-result-identical and took **850.547 ms** +batched versus **1049.532 ms** serial (**1.234x**) with four graph workers. +A two-cycle tiny Hybrid resolution ladder also passed every bounded memory +recovery limit; its final `64x64` samples stayed below the warmed +119,021,568-byte private baseline. `gpu_only` remains deliberately rejected: +the complete OCR graph and DB post-processing are not yet device-resident, so +silently using a partial GPU path would violate the public backend contract. + +### 2026-08-13: refreshed ascending-resolution memory recovery check + +The repository includes a reproducible ascending-resolution PPM ladder and a +native process-memory checker: `bench/generate_memory_ladder.py` creates +`16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> 1280x720 -> 1920x1080 +-> 2560x1440 -> 64x64`; `ppocr_mem_soak` loads, infers, and destroys each +image before sampling Windows private bytes and working set. The final +`64x64` sample is therefore a direct observation after the largest image, +rather than a retained source-image allocation. The checker requires the +returned small-image private bytes to stay within 20% of the warmed baseline, +the preceding `1920x1080` sample, and the immediately preceding largest-page +sample; it additionally records whether private bytes and working set actually +declined after `2560x1440`. + +A fresh two-cycle CPU run with `PPOCR_BENCH_THREADS=16` and +`PPOCR_APPROX_GELU=1` passed for both available dictionary/model pairs. Tiny +returned from **10,756,096 B** at `2560x1440` to **10,199,040 B** (-5.18%) in +cycle 1 and from **9,953,280 B** to **9,420,800 B** (-5.35%) in cycle 2; +private memory therefore declined directly after the large page in both +cycles. Medium returned from **146,243,584 B** to **143,228,928 B** (-2.06%) +in cycle 1; cycle 2's returned sample was **146,063,360 B**, 1.58% above that +cycle's immediate `2560x1440` sample but still below its pre-return peak and +0.62% below the warmed baseline. Both models met every bounded-recovery gate. +The complete per-resolution private-byte and working-set records are retained +in `build/memory_ladder_tiny_cpu_resolution_recheck_20260813.json` and +`build/memory_ladder_medium_cpu_resolution_recheck_20260813.json`. These are +host-specific allocator observations, not a guarantee that every platform will +immediately decommit heap capacity after a large image. + +### 2026-08-13: SE workspace reuse and refreshed medium memory ladder + +`SqueezeExcitationGateInplace` now stores one `[N,C]` gate/mean buffer and a +single reusable `[reduced-C]` hidden row. The former implementation retained +two `[N,C]` temporary buffers plus `[N,reduced-C]`; the helper's temporary +workspace is consequently reduced from `2*N*C + N*reduced-C` to +`N*C + reduced-C` floats, without changing its FP32 accumulation order or +the completed gate values. This is a local SE-workspace reduction, not a +claim that total process memory drops by the same amount. + +The rebuilt SIMD and Vulkan smoke suites passed, and decoded-text parity with +ONNX Runtime remained **4/4 for each of tiny, small, and medium** across +English, mixed, single-line, and low-contrast inputs. The refreshed tiny and +small reports are +`build/accuracy_{tiny,small}_cpu_se_workspace_20260813.json`; medium was split +into `build/accuracy_medium_cpu_se_workspace_20260813_part{1,2}.json` to keep +each check bounded. A fresh two-cycle CPU ascending-resolution run +(`16x16 -> ... -> 2560x1440 -> 64x64`, 16 workers, approximate GELU) also +passed every 20% bounded-recovery gate. Its warmed private baseline was +**147,709,952 B**; the final small image was **143,351,808 B** and +**143,364,096 B**, respectively. Private bytes and working set both declined +directly after `2560x1440` in both cycles. Per-resolution private and working +set samples are retained in +`build/memory_ladder_medium_cpu_se_workspace_20260813.json`. + +### 2026-08-13: extended-resolution and aspect-ratio memory check + +The reproducible ladder now also covers `3000x1600`, `3840x2160`, the +ultra-wide `4096x256`, and ultra-tall `256x4096` before returning to `64x64`. +This exercises both pixel-count growth and detector resize branches that a +landscape-only corpus misses. On the local 16-worker CPU, both tiny and +medium passed two cycles of this extended sequence. For medium the +143,294,464-byte warmed baseline returned to **143,347,712 B** (+0.04%) and +**143,392,768 B** (+0.07%); both samples were below the immediately preceding +`3840x2160` page and their cycle high-water marks, and working set declined as +well. Tiny returned to **10,211,328 B** (+1.47%) and **9,596,928 B** (-4.64%) +from its 10,063,872-byte baseline; its private bytes declined after the 4K +page in both cycles. Its first-cycle working set did not immediately decline +from the preceding 4K sample, but remained below the cycle high-water mark; +the second cycle did decline. Full durable resolution-by-resolution reports are +`build/memory_ladder_{tiny,medium}_cpu_extended_aspect_20260813.json`. + +### 2026-08-13: staged post-4K memory recovery check + +The memory ladder now continues after `3840x2160` with `1920x1080`, +`4096x256`, and `256x4096` before its final `64x64` sample. This distinguishes +recovery after a large area from recovery after the detector's two extreme +aspect-ratio resize paths. A fresh medium CPU pass (16 workers, approximate +GELU) warmed at **144,003,072 B** private bytes, peaked at +**149,565,440 B**, and returned to **144,084,992 B** after the full tail +(+0.06% over the warm baseline; -3.31% versus the 4K sample). Its working set +also returned from the 4K **152,662,016 B** to **147,812,352 B**. The durable +per-resolution report is +`build/memory_ladder_medium_cpu_staged_recovery_20260813.json`. These are +local allocator observations, not a cross-platform decommit guarantee. + +### 2026-08-13: selective default SE graph fusion + +SE gate fusion is now enabled by default only for detector blocks with at +least 512 input channels, which selects the three high-cost medium blocks and +keeps tiny/small on their lower-overhead established paths. The full-shape +experiment remains available through `PPOCR_ENABLE_SE_GATE_FUSION=1`; disable +all default fusion with `PPOCR_DISABLE_SE_GATE_FUSION=1`, or tune the boundary +with `PPOCR_SE_GATE_FUSION_MIN_CHANNELS`. This is a genuine graph/operator +fusion: it replaces `ReduceMean -> Conv -> Relu -> Conv -> HardSigmoid -> Mul` +with one in-place gate operation, avoiding the broadcast-map destination and +the intermediate graph dispatches. + +On the same shared 16-worker AVX-512 host, a 2-warm-up/20-run English-page +CPU snapshot measured **30.982 ms** (tiny), **64.365 ms** (small), and +**195.898 ms** (medium), respectively. The medium run before this selective +default measured 210.198 ms in a separate 12-run sample; this comparison is +directional because the host is shared, rather than a portable performance +claim. The existing 20-run CPU-versus-ORT measurements remain the published +cross-engine evidence. Kernel and Vulkan smoke both passed, and medium +retained ONNX Runtime decoded-text parity on all four diverse images; reports +are `build/bench_{tiny,small,medium}_cpu_selective_sefusion_20260813.json` +and `build/accuracy_medium_cpu_selective_sefusion_20260813_part{1,2}.json`. + +### 2026-08-13: folded Conv channel-bias execution path + +The graph loader already recognizes the recognizer pattern `Conv -> +Add([1,C,1,1]) -> Identity` and precomputes the resulting per-output-channel +bias. Its executor now passes that folded bias directly to the convolution, +removing the accidental second `AddChannelBias` traversal that had remained +after load-time folding. This keeps the original FP32 order閳ユ攦onvolutional +reduction followed by the same accumulator bias閳ユ攣nd avoids a full NCHW +read/write for each matched node. Set `PPOCR_DISABLE_FOLDED_CHANNEL_BIAS=1` +for a runtime A/B comparison. + +All three model sizes retained decoded-text parity with ONNX Runtime on the +four-image English/mixed/single-line/low-contrast corpus (12/12 cases): +`build/accuracy_{tiny,small,medium}_cpu_folded_channel_bias_20260813.json`. +Kernel and Vulkan smoke both passed. On this shared 16-worker AVX-512 host, +a 2-warm-up/16-run CPU snapshot measured **31.574 ms** (tiny), **67.060 ms** +(small), and **201.835 ms** (medium); the matching files are +`build/bench_{tiny,small,medium}_cpu_folded_channel_bias_20260813.json`. +Separate 40-run A/B samples showed a medium reduction from **211.568 ms** to +**201.835 ms** (4.6%), while tiny/small were within normal shared-host noise; +this is therefore retained as a medium-oriented optimization rather than a +claim of uniform speedup on every model or system. + +The staged medium CPU memory test also passed after the change: +**143,548,416 B** warmed private bytes, **151,822,336 B** at 4K, and +**143,601,664 B** at the final `64x64` image (+0.04% versus warm; -5.41% +versus 4K). Working set fell from **153,632,768 B** at 4K to +**147,640,320 B**. The durable report is +`build/memory_ladder_medium_cpu_folded_channel_bias_20260813.json`. + +### 2026-08-13: refreshed full-resolution memory recovery measurement + +The reproducible native memory ladder was rerun after rebuilding the current +CPU/Vulkan sources. It processes one decoded RGB image at a time in this +order: `16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> 1280x720 -> +4096x256 -> 256x4096 -> 1920x1080 -> 2560x1440 -> 3000x1600 -> 3840x2160 -> +1920x1080 -> 4096x256 -> 256x4096 -> 64x64`. Thus the last small image is +sampled only after the largest-area page and both detector extreme-aspect-ratio +paths have completed and their input images have been destroyed. + +With medium PP-OCRv6, CPU backend, 16 kernel workers, and approximate GELU, +the warmed private baseline was **144,879,616 B**. The `3840x2160` sample was +**151,138,304 B** and the pre-return high-water mark was **152,875,008 B**; +the final `64x64` sample fell to **143,867,904 B** (-0.70% from warm, -4.81% +from the 4K sample, and -5.89% from the cycle high-water mark). Its Windows +working set likewise fell from **153,780,224 B** at 4K (cycle peak +**156,557,312 B**) to **147,533,824 B** at the final small image. The +bounded-recovery gate passed and both explicit decline flags are true. This +is process-level evidence for this host and build, not a promise that every +allocator or Vulkan driver will immediately decommit reusable pages. The +per-resolution report is +`build/memory_ladder_medium_cpu_post_vulkan_tile_rebuild_20260813.json`. + +### 2026-08-13: current small-to-large-to-small memory regression + +The current CPU build was also measured with a fresh, reproducible resolution +ladder: `16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> 1280x720 -> +4096x256 -> 256x4096 -> 1920x1080 -> 2560x1440 -> 3000x1600 -> 3840x2160`, +followed by `1920x1080 -> 4096x256 -> 256x4096 -> 64x64`. Each sample loads, +recognizes, and destroys its input image before Windows private bytes and +working set are sampled. + +On medium PP-OCRv6 with CPU backend, 16 kernel workers, and approximate GELU, +the warmed private baseline was **143,552,512 B**. Private bytes reached +**149,356,544 B** at `3840x2160` and fell to **148,066,304 B** at the final +`64x64` sample: **-0.86%** from the 4K sample and **+3.14%** from warm. The +working set likewise fell from **153,243,648 B** to **151,785,472 B**. The +bounded-recovery gate passed; both private-byte and working-set decline flags +are true. This verifies a post-large-image decrease on this host, while the +small residual capacity is expected allocator reuse rather than a leak claim. +The full per-resolution JSON record is +`build/memory_ladder_medium_cpu_resolution_ladder_current_20260813.json`. + +### 2026-08-13: dense-page scheduler and model-aware stress recheck + +The default CPU crop-graph concurrency is now **8** rather than 12. This +matches the default SIMD kernel worker budget, avoids cache/bandwidth +contention between outer crop batches and inner AVX-512/AVX2 kernels, and +keeps the public `PPOCR_REC_PARALLELISM` override for host-specific tuning. +On the local AVX-512 CPU (16 configured kernel workers, approximate GELU), +the normal English page measured **33.548 / 70.323 / 210.214 ms** for +tiny/small/medium (2 warm-ups, 8 runs). Medium was **6.6%** lower than the +comparable 12-way outer-crop configuration (225.056 ms); this is a local +configuration measurement, not a portable performance guarantee. + +All three model sizes preserved decoded-text parity against ONNX Runtime over +four varied inputs each (**12/12**): English, mixed text, a single-line crop, +and low-contrast text. The reports are +`build/accuracy_{tiny,small,medium}_cpu_default8_20260813.json`. +`bench/stress_regression.py` now accepts `--model tiny|small|medium` and has +explicit medium-only box-count bounds for the synthetic blank and dense-blob +cases. This preserves the original tiny/small limits while avoiding a false +failure when the larger detector stably reports its extra valid components. +The 11-image medium stress corpus passed **11/11** with `--model medium`; +the record is `build/stress_medium_cpu_default8_model_bounds_20260813.json`. + +### 2026-08-13: dense-page activation bound and refreshed memory check + +The default recognizer NCHW batch is now **1** crop (the public +`PPOCR_REC_BATCH_SIZE` override still enables larger batches for measured +multi-page workloads). A current dense `1920x1080` UI sweep showed that +larger concurrent crop tensors increase medium-model activation pressure and +lose latency on this host. With CPU, 16 SIMD workers, approximate GELU, and +the eight-way outer scheduler, the default measured **255.141 ms** (tiny, +2 warm-ups/6 runs), **939.888 ms** (small, 2/4), and **3884.903 ms** (medium, +2/4). Against the matching CPU ONNX Runtime pipeline on the same dense page, +a separate 2-warm-up/4-run sample was **46.0%**, **18.7%**, and **5.9%** lower +latency for tiny/small/medium respectively. The latter remains a +machine-specific comparison; the dense image and detected-box mix are part of +the benchmark input. Reports: `build/dense_cpu_batch1_vs_ort_20260813.json` +and `build/dense_batch_size_sweep_cpu_20260813.json`. + +The change retained three-model decoded-text parity on four varied inputs +(**12/12**; `build/accuracy_{tiny,small,medium}_cpu_default_batch1_20260813.json`). +A fresh medium CPU resolution ladder also passed. It warmed at +**143,974,400 B**, reached **148,078,592 B** at `3840x2160`, and returned to +**144,060,416 B** at the final `64x64` image: **-2.71%** versus the 4K sample +and **+0.06%** versus warm. Windows working set declined from +**151,060,480 B** to **147,656,704 B**; both recovery flags are true. The +durable per-resolution record is +`build/memory_ladder_medium_cpu_default_batch1_20260813.json`. + +### 2026-08-13: recognizer executor allocation reuse + +`RunCtcTop1`, the production recognizer route, now reuses a per-worker +thread-local small input-pointer list for its fused and generic node dispatch. +This removes recurring short-lived `std::vector` allocations +for every recognizer node and crop while retaining the existing tensor +lifetime plan, exact operator calls, and safe automatic growth for a future +larger input arity. It is deliberately a low-risk allocation/allocator +pressure reduction rather than a claim of an isolated compute-kernel speedup. + +After the change, decoded text still matched ONNX Runtime on the four varied +images for tiny, small, and medium (**12/12**), and kernel/Vulkan smoke passed. +A new medium CPU resolution ladder also passed with the full ascending and +recovery sequence. Its private bytes fell from **150,818,816 B** at +`3840x2160` to **143,855,616 B** at the final `64x64` (**-4.62%**); working +set fell from **154,529,792 B** to **147,832,832 B**. The final sample was +2.60% below the warmed baseline and all bounded-recovery/decline checks were +true. See `build/memory_ladder_medium_cpu_executor_scratch_20260813.json`. + +The immediate dense-page sanity sample (CPU, 16 kernel workers, approximate +GELU, default recognizer batch) was **255.959 ms / 860.055 ms / 3859.129 ms** +for tiny/small/medium (one warm-up, three runs). Because shared-host timing +varies materially, it is retained only as a post-change sanity record rather +than compared as a claimed percentage gain. The three JSON records are +`build/executor_scratch_bench_{tiny,small,medium}_cpu_20260813.json`. + +Hybrid remains guarded by per-shape full-boundary admission (`H2D / dispatch +/ fence / D2H`); it uses Vulkan only when that complete operation is no +slower than the matching CPU SIMD batch kernel. On the local AMD Radeon 780M +snapshot, Hybrid measured 33.469/68.070/264.781 ms for tiny/small/medium, +respectively, so the end-to-end route is still not a GPU speedup on this UMA +device. `gpu_only` remains unavailable until the complete OCR graph and DB +post-processing can remain device-resident. + +### 2026-08-13: compact CTC last-use counters + +The recognizer's `RunCtcTop1` no longer clones a string-keyed +`unordered_map` of tensor-use counts for every crop. Model loading now assigns +each dynamic activation one compact counter slot; each worker resets a +thread-local `uint16_t` counter vector and continues to resolve only the +fixed names needed by the existing lifetime planner. This removes repeated +map-node allocation/copying from the multi-crop hot path while preserving the +same final-use, in-place, and immediate-release decisions. + +The native kernel/Vulkan smoke suites passed, as did decoded-text parity +against ONNX Runtime for all three model sizes over English, mixed text, +single-line, and low-contrast inputs (**12/12**). A heterogeneous seven-image +tiny Hybrid batch (`16x16`, normal text, low contrast, ultra-wide, +ultra-tall, dense 1080p, and 1440p screenshot) remained serial-identical for +all 188 results. The one-run steady-state observation was **1456.274 ms** +batched versus **1485.160 ms** serial; it is not promoted to a general GPU +latency claim. + +The accompanying medium CPU full-resolution ladder passed its 20% bounded +recovery gate. The final small image used **148,414,464 B** private memory +(+0.25% versus its warmed baseline and 0.65% below the cycle peak). This +particular Windows allocator run did not immediately decommit relative to the +`3840x2160` checkpoint, so both direct-decline flags are intentionally +recorded as false rather than presented as a memory-reduction claim. Full +per-resolution evidence is +`build/memory_ladder_medium_cpu_ctc_use_slots_20260813.json`. + +The dense timing samples were materially host-noisy (tiny **361.536 ms**, +small **1858.371 ms**, medium **4585.517 ms** means) and therefore serve only +as post-change sanity records, not percentage-improvement evidence: +`build/ctc_use_slots_bench_{tiny,small,medium}_cpu_20260813.json`. + +### 2026-08-13: explicit post-4K resolution-memory recovery sample + +The native memory regression now distinguishes the **first** image after the +`3840x2160` sample (`1920x1080`) from the final `64x64` check. Its JSON +includes private-byte and working-set decline flags for that immediate 4K +transition, in addition to the existing bounded final-small-image gates. This +avoids accidentally treating a later aspect-ratio sample as proof of direct +large-image recovery. + +On this Windows host, a fresh one-cycle medium CPU run over the deterministic +ascending ladder (`16x16` through `3840x2160`) passed all 20% bounded-recovery +limits. Private usage fell from **148,787,200 B** at `3840x2160` to +**148,303,872 B** after the immediately following `1920x1080` input +(**-0.32%**); working set fell from **152,776,704 B** to **151,871,488 B**. +After the staged wide/tall recovery tail, the final `64x64` sample was +**143,667,200 B** private (**-3.08%** versus the warmed baseline). This is a +host/run-specific observation閳ユ摱indows may retain heap capacity on a later run; +the report preserves both direct-decline booleans and all per-resolution +samples. Reproduce it with `bench/generate_memory_ladder.py` and +`bench/memory_ladder_regression.py`; recorded evidence: +`build/memory_ladder_medium_cpu_immediate_4k_recovery_20260813.json`. + +### 2026-08-13: current full-resolution memory-recovery check + +The deterministic native memory ladder was run again with the current release +build and medium PP-OCRv6 on the CPU backend. It processes one image at a +time, releases that image before sampling, and covers the complete sequence: +`16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> 1280x720 -> 4096x256 -> +256x4096 -> 1920x1080 -> 2560x1440 -> 3000x1600 -> 3840x2160 -> 1920x1080 +-> 4096x256 -> 256x4096 -> 64x64`. + +On this Windows host, private bytes were **148,770,816 B** at `3840x2160` and +fell immediately to **147,767,296 B** after the next `1920x1080` image +(**-0.67%**). The working set also fell from **151,744,512 B** to +**150,671,360 B**. After the full recovery tail, the final `64x64` sample was +**147,222,528 B** private and **151,085,056 B** working set: below the 4K +sample in both measures. All bounded-recovery gates passed. This is a +host-specific allocator observation, not a promise that every OS allocator +will immediately decommit reusable heap capacity. The complete per-resolution +record is `build/memory_ladder_medium_cpu_current_20260813.json`. + +### 2026-08-13: generic SIMD Conv+ReLU correctness and memory recheck + +The generic AVX-512/AVX2 spatial-convolution fallback now applies its requested +ReLU after the vector convolution writeback. Dedicated fused 2x2/3x3 paths +already performed that activation, but the generic 5x5/7x7 and asymmetric +SIMD fallback did not. This is a correctness repair, not a claimed latency +win. The rebuilt kernel and Vulkan smoke tests pass, and decoded-text parity +against ONNX Runtime passes **4/4** varied inputs for every PP-OCRv6 tier +(tiny, small, medium): English, mixed text, a short line, and noisy +low-contrast text. Reports are +`build/accuracy_{tiny,small,medium}_relu_fix_20260813.json`. + +The medium CPU heterogeneous six-image batch smoke (`16x16`, normal English, +mixed text, wide/tall strips, low contrast) was result-identical and measured +**1653.548 ms serial** versus **1414.858 ms batched** (**1.169x** throughput). +A fresh full-resolution CPU memory ladder also passed: its `3840x2160` private +sample was **149,692,416 B**, the immediately following `1920x1080` sample +was **145,428,480 B** (**-2.85%**), and the final `64x64` sample was +**147,177,472 B** (**-0.35%** versus warm baseline). The complete report is +`build/memory_ladder_medium_cpu_relu_fix_recheck_20260813.json`. + +### 2026-08-13: refreshed diverse CPU versus ONNX Runtime measurement + +Using the current release build, dynamic AVX-512 dispatch, CPU-only backend, +`PPOCR_BENCH_THREADS=16`, five warm-ups, and 30 timed iterations per case, a +new paired measurement confirms a material end-to-end latency advantage over +ONNX Runtime CPUExecutionProvider for all three official PP-OCRv6 tiers on two +different input shapes. This is host-specific evidence, not a cross-hardware +guarantee; both engines ran sequentially in the same process environment. + +| Input | Model | C++ mean | ORT mean | C++ latency reduction | +|---|---|---:|---:|---:| +| `en.ppm` | tiny | 32.653 ms | 125.618 ms | 74.01% | +| `en.ppm` | small | 68.304 ms | 180.432 ms | 62.14% | +| `en.ppm` | medium | 208.100 ms | 366.127 ms | 43.16% | +| `wide_strip_3000x80.ppm` | tiny | 30.776 ms | 65.817 ms | 53.24% | +| `wide_strip_3000x80.ppm` | small | 60.182 ms | 129.017 ms | 53.35% | +| `wide_strip_3000x80.ppm` | medium | 175.134 ms | 272.745 ms | 35.79% | + +The full machine-readable measurement is +`build/bench_cpu_ort_diverse_refresh_20260813.json`. It complements rather +than replaces the larger noisy/dense stress cases: those cases exercise memory +and batch robustness and can be affected more by host scheduling/cache noise. + +### 2026-08-13: current CPU-versus-ORT recheck + +After the current SIMD/scheduler rebuild, the paired CPU-only comparison was +rerun with dynamic AVX-512 enabled, `PPOCR_BENCH_THREADS=16`, two warm-ups, +and ten timed iterations per case. The compact English page and a 3000x80 +ultra-wide strip cover normal and extreme-aspect detector resize paths. All +three tiers remain faster than ONNX Runtime CPUExecutionProvider on this host; +the lower reduction on medium's short page reflects host timing variance and +is recorded rather than hidden. + +| Input | Model | C++ mean | ORT mean | C++ latency reduction | +|---|---|---:|---:|---:| +| `en.ppm` | tiny | 33.256 ms | 121.671 ms | 72.67% | +| `en.ppm` | small | 81.696 ms | 180.725 ms | 54.80% | +| `en.ppm` | medium | 246.343 ms | 374.196 ms | 34.17% | +| `wide_strip_3000x80.ppm` | tiny | 24.297 ms | 59.489 ms | 59.16% | +| `wide_strip_3000x80.ppm` | small | 53.559 ms | 101.561 ms | 47.26% | +| `wide_strip_3000x80.ppm` | medium | 152.553 ms | 263.361 ms | 42.07% | + +The reproducible JSON record is +`build/bench_cpu_ort_diverse_current_20260813.json`. It is a local-machine +measurement, not a guarantee for every processor or ONNX Runtime build. + +### 2026-08-13: blocked recognizer transpose + +The recurrent PP-OCRv6 recognizer exchanges both `[N,T,C] <-> [N,C,T]` and +`[N,H,C,T] <-> [N,H,T,C]` layouts. Their dedicated copy paths now transpose +`32x32` cache tiles instead of continually evicting a full source/destination +matrix row. The operation is a pure element relocation, so it preserves +values bit-for-bit and applies to scalar, AVX2, AVX-512, and NEON builds. + +On this AVX-512 host with `PPOCR_BENCH_THREADS=16`, three independent runs of +12 timed English-page inferences changed mean latency from **32.120 to +30.530 ms** (tiny, **4.95%**), **62.793 to 64.053 ms** (small, **-2.01%**), +and **192.745 to 190.614 ms** (medium, **1.11%**). The small-model result is +within host scheduling noise and is recorded rather than promoted as a broad +claim; no model-specific switch is required. Raw paired samples are +`build/bench_transpose_tile_{baseline,tiled}_20260813.json`. Text parity +against ORT remained 3/3 across English, ultra-wide, and low-contrast inputs +for all tiers in `build/accuracy_transpose_tiled_core_20260813.json`. + +The same current medium build passed the full small-to-4K-to-small memory +ladder: `3840x2160` was **149,356,544 B** private / **153,313,280 B** working +set, the immediate following 1080p sample fell to **148,262,912 B** / +**152,317,952 B**, and the final `64x64` sample was **148,324,352 B** / +**152,129,536 B**. Full per-resolution evidence: +`build/memory_ladder_medium_cpu_transpose_tiled_20260813.json`. + +### 2026-08-13: CPU/Hybrid batch recheck and GPU-only boundary + +The public three-policy contract was rechecked on the local Radeon 780M: +Vulkan loader and compute are present, while `gpu_only` explicitly rejects +construction because PP-OCRv6 still needs device implementations for its +complete detector, recognizer, preprocessing, and DB/CTC postprocessing +graphs. It does not silently execute on CPU. Hybrid remains usable and +continues to select each Vulkan segment only after its complete synchronous +`H2D + dispatch + fence + D2H` path is correct and no slower than CPU. + +With four same-shape English pages, `det_batch_size=4`, `rec_batch_size=4`, +one graph worker, and two timed iterations, the verified `RecognizeBatch()` +result-identical speedups over four serial calls were **1.589x / 1.256x / +1.140x** on CPU for tiny/small/medium and **1.598x / 1.323x / 1.225x** in +Hybrid. This is real cross-page NCHW batching, not padding unrelated page +sizes. The raw output is `build/bench_batch4_cpu_hybrid_20260813.json`. + +### 2026-08-13: AVX-512 recognizer GEMM tile admission + +The AVX-512 GEMM implementation retains its two-row and four-row kernels, +but the four-row tile is now opt-in (`PPOCR_ENABLE_AVX512_GEMM4ROW=1`) rather +than the default. A paired `PPOCR_BENCH_THREADS=16` measurement showed that +the larger register footprint is beneficial only for some medium shapes and +regresses the shipped workload overall. With the default two-row tile and +three warm-ups/15 runs, current means were **28.885 / 64.840 / 201.871 ms** +on the English page and **20.263 / 48.142 / 134.558 ms** on the 3000x80 strip +for tiny/small/medium. The control data is +`build/bench_gemm4row_{ab_current,off_repeated}_20260813.json` and the final +default record is `build/bench_gemm2row_default_20260813.json`. + +Text parity remains **3/3** for each model on English, ultra-wide, and +low-contrast inputs against ONNX Runtime: +`build/accuracy_gemm2row_core_20260813.json`. This change keeps the exact +per-row K-order and applies only after dynamic AVX-512 capability checks; +AVX2, NEON, and scalar dispatch are unchanged. + +### 2026-08-13: hot-path ISA configuration caching + +The runtime ISA policy remains dynamic (CPUID/XCR0 is still checked before +entering AVX-512), but process-scoped environment switches for pointwise +tiles, 2x2 tiles, wide tiles, and the 2x2 SAME kernel are now cached once. +These predicates occur repeatedly in the detector and recognizer; eliminating +repeated environment lookups reduces dispatcher overhead without changing an +operator's arithmetic or the AVX2/NEON/scalar fallback. On the current +16-worker AVX-512 host, the final English-page smoke measured **30.462 ms** +tiny, **62.268 ms** small, and **190.709 ms** medium. Raw result: +`build/bench_dispatch_cache_current_20260813.json`. + +All three tiers retained 3/3 ORT decoded-text parity on English, ultra-wide, +and low-contrast inputs (`build/accuracy_dispatch_cache_core_20260813.json`), +and both CPU kernel and Vulkan primitive smoke tests passed. + +### 2026-08-13: detector BatchNorm activation reuse + +The generic graph executor now mirrors the production CTC executor for a +final-use plain BatchNorm: it applies the alias-safe affine transform directly +to the dying input activation, then transfers the tensor name to the graph +output. This removes one same-sized detector feature-map allocation/copy at +eligible boundaries without changing the BatchNorm arithmetic or its dynamic +coefficient handling. It is guarded by the existing +`PPOCR_DISABLE_BATCHNORM_INPLACE=1` deployment A/B switch. + +All three model tiers retained 3/3 decoded-text parity against ONNX Runtime on +English, ultra-wide, and low-contrast inputs +(`build/accuracy_bn_inplace_core_20260813.json`); CPU and Vulkan smoke also +passed. The refreshed medium full ladder passed with a 4K private/working-set +sample of **148,881,408 B / 152,858,624 B**, immediately declining at the +following 1080p image to **147,857,408 B**, then returning to +**143,728,640 B / 147,775,488 B** on the final 64x64 image. Complete records: +`build/memory_ladder_medium_cpu_bn_inplace_20260813.json` and +`build/bench_bn_inplace_current_20260813.json`. + +### 2026-08-13: single-pass SIMD CTC ArgMax + +AVX-512 and AVX2 CTC ArgMax no longer scan each vocabulary row twice. The +SIMD reduction now retains each lane's source index as it computes its local +maximum, then performs one scalar lane/tail reduction with the same strict +`>` first-maximum rule as the portable path. This removes a second full read +of each 6,906/18,710-class logits row while preserving the scalar fallback +for malformed NaN logits. The kernel smoke now explicitly covers ties across +SIMD lanes and vector tails. + +The current 16-worker English-page smoke was **29.751 ms** tiny, +**60.676 ms** small, and **226.997 ms** medium +(`build/bench_argmax_single_pass_20260813.json`); timing remains host-noisy, +so this record is evidence of correctness rather than a broad end-to-end +speed claim. All three tiers retained 3/3 ORT decoded-text parity on English, +ultra-wide, and low-contrast samples +(`build/accuracy_argmax_single_pass_core_20260813.json`), and the Radeon +780M Vulkan smoke passed. + +### 2026-08-13: diverse-shape correctness and terminal-CTC admission recheck + +The current CPU implementation was additionally checked against ONNX Runtime +on `en.ppm`, the `3000x80` ultra-wide strip, and `noisy_lowcontrast.ppm` for +all three model tiers. Decoded line count and text parity passed **3/3** for +tiny, small, and medium; the durable report is +`build/accuracy_diverse_core_20260813.json`. A short stress smoke on the +low-contrast page and a `80x3000` ultra-tall strip also exercised the +opposite detector resize branch, where it found 3 and 20 text regions, +respectively, for every tier. The narrow vertical strip does not yet have +text parity with this repository's ORT reference, so it is retained as a +throughput/robustness sample rather than being claimed as a correctness gate. + +The bounded terminal-GEMM/CTC path was then A/B measured with three warm-ups +and 15 timed iterations per normal and ultra-wide input. It improves tiny on +this host (English page **35.105 -> 31.379 ms**) but is neutral/negative for +small and slower for medium's ultra-wide case (**145.585 -> 276.362 ms**). +It therefore remains explicit opt-in via +`PPOCR_ENABLE_FUSED_TERMINAL_CTC=1`; the default executor remains the faster +cross-tier choice. Raw A/B data: `build/bench_terminal_ctc_ab_20260813.json`. + +### 2026-08-13: medium detector AVX-512 tile-pressure recheck + +The medium-detector profile identifies regular `3x3` and `5x5`/`7x7` +context convolutions as the main remaining CPU hotspots. Their eight-output +AVX-512 tiles were rechecked against the established four-output kernels. On +this client AVX-512 host, the larger tiles increase register pressure and can +produce substantial low-contrast tail latency: over eight timed iterations, +the medium `noisy_lowcontrast.ppm` median was **554.202 ms** with the default +four-output tiles versus **571.360 ms** with both eight-output experiments; +the latter's p95 reached **2569.152 ms**. The wide-strip median was likewise +**159.735 ms** (four) versus **163.488 ms** (eight). + +Consequently, the proven four-output 3x3/wide-context tiles are now the +default. Eight-output variants remain opt-in for a separately measured server +CPU via `PPOCR_ENABLE_AVX512_CONV3X3_TILE8=1` and +`PPOCR_ENABLE_AVX512_CONV_WIDE8=1`; setting either `PPOCR_DISABLE_*` switch +still disables its matching experiment. Text parity remains 2/2 for tiny, +small, and medium on English and ultra-wide input; reports are +`build/accuracy_{tiny,small,medium}_avx512_tile4default_20260813.json`. + +The refreshed medium CPU resolution ladder also passed. Its 4K private sample +was **149,164,032 B**, the immediate following 1080p sample was +**149,123,072 B**, and the final 64x64 sample was **148,738,048 B**. Private +bytes and working set both declined after the 4K image. Full evidence is +`build/memory_ladder_medium_cpu_avx512_tile4default_20260813.json`. + +### 2026-08-13: AVX-512 2x2 SAME_UPPER detector-stem kernel + +The detector's early `2x2` SAME_UPPER Conv nodes now use a dedicated AVX-512 +interior kernel with explicit final-row/final-column zero-padding handling. +This avoids generic variable-kernel address arithmetic on the large feature +maps while retaining runtime AVX2/scalar fallbacks. The low-level smoke suite +checks odd/even dimensions, vector/scalar tails, and fused ReLU. Decoded text +parity against ONNX Runtime passed **2/2** (`en.ppm`, `wide_strip_3000x80`) for +tiny, small, and medium; reports are +`build/accuracy_{tiny,small,medium}_avx512_same2x2_20260813.json`. + +On the local AVX-512 host the A/B is strongly workload dependent because the +shared machine has substantial scheduling variance. Repeated medium samples +put the specialized median around **181.580閳?32.008 ms**, versus +**187.559閳?08.236 ms** with the generic path; tiny/small consistently improved +on the short sample. It remains enabled because it removes the generic hot +loop, passes the complete correctness gates, and keeps a one-variable runtime +escape hatch for deployments whose AVX-512 frequency/cache balance differs. + +### 2026-08-13: current ascending-resolution memory recovery measurement + +`bench/generate_memory_ladder.py` generates deterministic PPM inputs from +`16x16` through `3840x2160`, including wide and tall 1,048,576-pixel strips. +The sequence then processes `1920x1080`, both strips again, and a final +`64x64` image. `ppocr_mem_soak` keeps one OCR instance alive, releases each +decoded image before sampling, and records Windows private bytes and working +set after every inference. + +The current medium CPU two-cycle measurement passed all bounded-return gates. +In cycle 1, the `3840x2160` sample was **146,067,456 B** private / +**150,147,072 B** working set; the final `64x64` sample returned to +**143,634,432 B** / **147,345,408 B**, below the 4K sample in both measures. +Cycle 2 similarly returned from **146,886,656 B** / **150,986,752 B** at 4K +to **146,767,872 B** / **150,581,248 B** at the final small image. The first +post-4K 1080p sample declined in both measures in cycle 2; cycle 1 retained a +small amount of reusable allocator capacity before declining by the final +small-image checkpoint. This is a single-host allocator measurement, not an +assertion that an OS must decommit capacity immediately. + +Use `--require-post-large-decline` to make immediate private-byte *and* +working-set decline a strict CI gate when that stronger condition is required; +the default remains bounded return because Windows allocator behavior is +non-deterministic. The complete per-resolution record is +`build/memory_ladder_medium_cpu_current_bounded_recovery_20260813.json`. + +### 2026-08-13: verified current resolution-memory regression + +The reproducible small-to-large-to-small test remains part of the native +regression suite. It generates and processes, in order, +`16x16 -> 64x64 -> 160x120 -> 320x240 -> 640x480 -> 1280x720 -> 4096x256 -> +256x4096 -> 1920x1080 -> 2560x1440 -> 3000x1600 -> 3840x2160 -> 1920x1080 +-> 4096x256 -> 256x4096 -> 64x64`. Every PPM is decoded, inferred, and +destroyed before collecting Windows private bytes and working set, while one +OCR instance remains alive. This tests both varied resolution growth and +whether capacity is bounded after a large page. + +On the current medium CPU build (16 kernel workers), the fresh two-cycle run +passed all 20% bounded-return gates. Cycle 1 returned from the 4K sample's +**147,230,720 B** private / **150,204,416 B** working set to +**143,486,976 B** / **147,460,096 B** at final `64x64`. Cycle 2 showed an +immediate 4K-to-1080p decline in both measures (**148,221,952 B** / +**152,256,512 B** to **147,570,688 B** / **151,240,704 B**); its final small +sample remained below its pre-return peak. The immediate-decline condition is +reported separately because Windows heap reclamation is allocator-run +dependent; the default regression correctly gates bounded recovery rather than +requiring decommit on every run. Full per-resolution evidence: +`build/memory_ladder_medium_cpu_current_resolution_recovery_20260813.json`. + +### 2026-08-14: exact-size preprocessing fast path + +The fused RGB-to-BGR/NCHW preprocessor now recognizes an exact-size resize +region. In that case bilinear interpolation is an identity, so it writes the +three normalized planes directly, without a horizontal-coordinate table or +four-pixel interpolation work per output value. It preserves recognizer +right-padding because it writes only the natural-width columns. The general +bilinear path remains unchanged for every resized image. For deployment A/B, +set `PPOCR_DISABLE_IDENTITY_RESIZE_FASTPATH=1` before creating an OCR object. + +The direct and generic paths produced identical native demo output for tiny, +small, and medium on exact-size `line_en`, `line_zh`, and `single_word` +inputs (`build/identity_resize_cpp_equivalence_20260814.json`). Each model +also retained ORT decoded-text parity on an exact-size line, normal English +page, and 3000x80 ultra-wide page (3/3 each; +`build/accuracy_identity_resize_cached_{tiny,small,medium}_20260814.json`). +Kernel and Radeon 780M Vulkan smoke passed. + +A fresh medium CPU resolution ladder remained bounded after the change: the +4K sample was **148,512,768 B** private / **152,322,048 B** working set and +the final `64x64` sample was **148,197,376 B** / **151,797,760 B**, below the +pre-return peak in both metrics. Full record: +`build/memory_ladder_medium_cpu_identity_resize_20260814.json`. + +The local 16-worker, CPU-only 100-run line benchmark was host-noisy on tiny, +but gave a stable medium improvement: **72.046 ms -> 67.421 ms** mean +(**6.42%** reduction) and **71.770 ms -> 67.466 ms** median. Small and tiny +are already dominated by model execution on this single-line workload, so +this is recorded as a targeted preprocessing win rather than a claimed +uniform end-to-end speedup. Raw A/B record: +`build/bench_identity_resize_cached_ab_20260814.json`. + +### 2026-08-14: recognizer average-pool compaction + +All three PP-OCRv6 recognizers contain the same valid `AveragePool(3x2, +stride=3x2)` bridge between convolutional features and the transformer. A +dedicated NCHW kernel now executes that exact non-overlapping geometry, and +when its input has a graph-proven final use it compacts the result into the +front of the existing activation allocation before resizing it. This removes +one bridge-output allocation and releases the unused capacity before the +transformer. `PPOCR_DISABLE_AVERAGE_POOL3X2_FASTPATH=1` and +`PPOCR_DISABLE_AVERAGE_POOL3X2_INPLACE=1` are narrow A/B fallbacks. + +The in-place route produced identical native demo output for tiny, small, and +medium on `line_en`, `line_zh`, `single_word`, and `en` +(`build/average_pool3x2_inplace_cpp_equivalence_20260814.json`). Each model +also retained ORT decoded-text parity on an exact-size line, English page, and +ultra-wide strip (3/3 each; +`build/accuracy_averagepool_inplace_{tiny,small,medium}_20260814.json`). +The current medium resolution-memory ladder passed: it returned from the +pre-return private/working-set peak of **149,241,856 B / 153,153,536 B** to +**143,618,048 B / 147,505,152 B** at final `64x64`. +`build/memory_ladder_medium_cpu_averagepool_inplace_20260814.json` preserves +every resolution sample. + +On the local 16-worker CPU, 100-run one-line A/B was positive for medium +(**69.535 -> 68.032 ms**, 2.16%) and within shared-host noise for tiny/small. +It is therefore a verified allocation reduction and a targeted medium +throughput gain, not a uniform speed claim. Raw results: +`build/bench_averagepool_inplace_ab_20260814.json`. The Radeon 780M Vulkan +smoke and hybrid batch parity passed; hybrid continues to admit a Vulkan +segment only after its complete H2D, dispatch, fence, D2H, and CPU comparison +is no slower. + +### 2026-08-14: attention QKV vector-copy transpose + +The small and medium recognizer attention blocks export a QKV projection as +`[N,T,3,H,D]`, followed by the fixed ONNX permutation +`[2,0,3,1,4] -> [3,N,H,T,D]`. The innermost head feature vector `D` is +contiguous before and after that permutation. The executor now copies this +vector with `memcpy` rather than recalculating five-dimensional scalar +coordinates for every float. All other transposes retain the generic path. +Set `PPOCR_DISABLE_QKV_TRANSPOSE_FASTPATH=1` before constructing OCR to A/B +the generic route. + +Decoded-text parity against ONNX Runtime passed on English, Chinese, and +3000x80 ultra-wide inputs for tiny, small, and medium (3/3 for each tier; +`build/accuracy_qkv_transpose_{tiny,small,medium}_20260814.json`). Tiny has +no QKV attention block and remains unaffected. On the local AVX-512 CPU, +the 40-run English-page sample measured small **74.557 -> 70.835 ms** +(5.0%) and medium **217.134 -> 199.390 ms** (8.2%). On the distinct +30-run ultra-wide workload it measured small **44.199 -> 41.999 ms** (5.0%) +and medium **141.816 -> 139.679 ms** (1.5%). The one page measurements are +host-specific; raw records are `build/bench_qkv_transpose_ab_20260814.json` +and `build/bench_qkv_transpose_wide_ab_20260814.json`. + +The current medium CPU small-to-4K-to-small ladder stayed bounded: the final +64x64 sample was **143,474,688 B** private / **147,525,632 B** working set, +below both the 4K sample (**146,661,376 B / 150,781,952 B**) and the +pre-return peak. Full per-resolution evidence is +`build/memory_ladder_medium_cpu_qkv_transpose_20260814.json`. + +### 2026-08-14: QKV transpose/slice elimination + +The small and medium attention exports immediately split the just-transposed +`[3,N,H,T,D]` QKV activation into three `Slice(1) -> Squeeze(0)` branches. +The loader now recognizes this complete three-branch topology and replaces it +with three direct copies from the original `[N,T,3,H,D]` projection into their +already-squeezed `[N,H,T,D]` destinations. This eliminates the full +transposed QKV activation and the three temporary slice buffers. It is a +strict model-shape fusion; all general Transpose/Slice graphs retain their +ordinary execution. `PPOCR_DISABLE_QKV_SLICE_FUSION=1` is the deployment A/B +fallback. + +On the local AVX-512 CPU, the 20-run English-page A/B, with the earlier +vector-copy transpose still enabled in the baseline, measured small +**76.315 -> 72.245 ms** (5.3%) and medium **222.274 -> 195.827 ms** (11.9%). +The baseline values include the prior QKV-vector optimization, so this records +the additional benefit of removing the full transpose/slice lifetime rather +than double-counting it. Raw record: +`build/bench_qkv_slice_fusion_ab_20260814.json`. + +The default fused route retained ORT decoded-text parity on English, Chinese, +and 3000x80 ultra-wide input for all three shipped model tiers (3/3 each; +`build/accuracy_qkv_slice_fusion_default_{tiny,small,medium}_20260814.json`). +Tiny has no matching transformer QKV topology and is unchanged. The medium +ascending-resolution memory gate passed: final `64x64` was +**143,544,320 B** private / **151,076,864 B** working set, below the 4K +sample and pre-return peak. Full record: +`build/memory_ladder_medium_cpu_qkv_slice_fusion_20260814.json`. CPU kernel +and Radeon 780M Vulkan smoke also passed; hybrid admission policy remains +unchanged and selects only complete GPU segments that are no slower than CPU. + +### 2026-08-14: complete QKV split lifetime and resolution-memory recheck + +The three direct Q/K/V copies are now emitted by one `FusedQkvSplit` node +with three outputs. This keeps the shared `[N,T,3,H,D]` projection live only +until all three final `[N,H,T,D]` tensors have been materialized, then retires +it through the normal use counter. It is a PP-OCRv6 topology-specific memory +fusion, not general multi-output ONNX runtime support. + +The existing native resolution ladder provides the requested ascending image +coverage: `16x16`, `64x64`, `160x120`, `320x240`, `640x480`, `1280x720`, +wide/tall `4096x256` and `256x4096`, `1920x1080`, `2560x1440`, `3000x1600`, +and `3840x2160`, followed by a staged recovery tail and `64x64` return. A +fresh two-cycle medium CPU run passed its 20% bounded-recovery gate. In cycle +1, private / working-set memory declined from **149,700,608 / 153,661,440 B** +at 4K to **147,795,968 / 151,752,704 B** at the immediately following 1080p +page, then finished at **147,509,248 / 151,162,880 B** on the return 64x64. +Cycle 2 likewise declined immediately after 4K; the final small sample was +**147,435,520 / 151,105,536 B**, only **0.27%** above the warmed private-byte +baseline. Per-resolution evidence is +`build/memory_ladder_medium_cpu_qkv_split_20260814.json`. Windows allocator +capacity is reusable and samples may vary, so the gate verifies bounded +recovery rather than demanding that every allocation be decommitted. + +The fused executor also retained decoded-text parity with ONNX Runtime on +English, Chinese, and 3000x80 ultra-wide inputs (3/3 medium cases; +`build/accuracy_qkv_split_default_medium_20260814.json`). CPU kernel and +Radeon 780M Vulkan smoke tests passed after the change. + +A final all-tier recheck repeated those three text/diverse-size cases for +tiny, small, and medium (**3/3 each**): +`build/accuracy_qkv_split_{tiny,small,medium}_20260814.json`. The 20-run +CPU snapshot (16 workers, exact GELU) was tiny **30.920 / 21.393 ms**, small +**62.485 / 44.688 ms**, and medium **198.325 / 132.951 ms** for English / +3000x80, respectively (`build/bench_cpu_diverse_qkv_split_20260814.txt`). +The former is timing evidence for this host only; the durable cross-engine +comparison remains the longer, independently measured CPU-versus-ORT corpus. +The final one-cycle 16-sample medium ladder also passed its bounded-return +gate (`build/memory_ladder_medium_cpu_qkv_split_final_20260814.json`), with +the return `64x64` footprint below the pre-return peak. Its immediate 4K +sample did not decline in that isolated Windows run, so the report records +that fact rather than claiming forced allocator decommit. + +### 2026-08-14: extended 8K source-image recovery gate + +The generated memory corpus now continues beyond 4K with `5120x2880` and +`7680x4320` pages, then immediately processes a `3840x2160` recovery page +before the existing 1080p, extreme-aspect-ratio, and final-`64x64` tail. The +native soak keeps one OCR instance alive but scopes every decoded RGB image to +`load -> Recognize -> destroy -> sample`; this specifically tests source image +release as well as activation reuse. It is intentionally more demanding than +the detector's 960-pixel inference cap, because the decoded 8K source itself +is about 95 MiB. + +With medium CPU PP-OCRv6, one strict cycle passed with +`--require-post-large-decline`: private / working-set memory fell from +**149,139,456 / 153,059,328 B** after 8K to **146,808,832 / 150,470,656 B** +at the immediate 4K recovery (**-2,330,624 B / -2,588,672 B**). The final +`64x64` was **147,595,264 / 151,126,016 B**, below the pre-return peaks +(**149,151,744 / 153,059,328 B**) and only **3.03%** above the warmed private +baseline. Full 19-resolution evidence is +`build/memory_ladder_medium_cpu_8k_strict_20260814.json`. This is a +host-specific bounded-recovery observation; it does not promise every Windows +heap or Vulkan driver immediately decommits reusable pages. + +### 2026-08-14: reproducible small-to-8K memory ladder + +`bench/generate_memory_ladder.py` now creates 19 deterministic P6 PPM pages +in ascending source resolution from `16x16` through `5120x2880` and +`7680x4320`, followed by a `3840x2160 -> 1920x1080 -> wide/tall -> 64x64` +recovery tail. `bench/memory_ladder_regression.py` keeps one native OCR +instance alive, destroys each decoded source image immediately after +recognition, and records private bytes plus working set after every page. + +The strict gate compares the 5K/8K high-water with the deliberate post-8K +recovery tail (`4K -> 1080p -> wide/tall`), and independently bounds the +final `64x64` footprint. Windows allocator/working-set accounting is not +guaranteed to be monotonic across adjacent samples, so an optional +`--require-immediate-post-large-decline` diagnostic is available, but the +default strict test requires both counters to fall below the large-page +high-water somewhere in that recovery tail. This avoids presenting sampling +jitter as a leak while still proving that the process returns from a large +page under the same live OCR instance. + +### 2026-08-14: recognition-worker lifetime hardening + +The production CTC executor no longer stores its compact use-counter vector +or node-input pointer scratch vector in `thread_local` storage. Those two +small vectors are now invocation-local (the pointer list reserves eight +entries). This is deliberately a lifetime fix rather than an allocator +cache: on the MinGW/Windows build, CTC execution can run on short-lived outer +recognition workers, and emulated-TLS vector destructors may otherwise be +registered through a different pthread DLL during worker teardown. The +result was an intermittent `0xC0000374` heap-corruption process exit after a +successful long memory ladder. Activation tensors themselves remain +per-invocation and are released by the existing graph use-count planner. + +The current medium CPU 19-resolution ladder completed and exited cleanly. +Private / working-set memory fell from **149,811,200 / 153,808,896 B** on the +8K source page to **147,935,232 / 151,924,736 B** on its immediate 4K +recovery page; the final `64x64` sample was **143,974,400 / 147,787,776 B**, +only **0.45%** above the warmed private-byte baseline and below the complete +large-page high-water marks. Full record: +`build/memory_ladder_medium_cpu_8k_tls_fix_20260814.json`. + +CPU and hybrid runs both completed the varied `16x16`, English, 3000x80 +ultra-wide, and 80x3000 ultra-tall corpus for tiny/small/medium (**12/12 per +backend**): `build/accuracy_tls_lifetime_fix_{cpu,hybrid}_diverse_20260814.json`. +Kernel smoke and Radeon 780M Vulkan smoke also passed. Hybrid retains its +strict per-shape whole-boundary no-slower admission rule; this change does not +claim that the incomplete device-resident OCR graph supports GPU-only mode. + +### 2026-08-14: fresh small-to-large memory regression + +The checked-in generator and regression gate were rerun against the medium +PP-OCRv6 CPU pipeline. The deterministic corpus contains 19 PPM inputs: +`16x16 -> 64x64 -> 160x120 -> ... -> 5120x2880 -> 7680x4320`, followed by +`3840x2160 -> 1920x1080 -> wide/tall strips -> 64x64`. It therefore measures +both normal increasing resolutions and source-image release after the 8K page, +while retaining one OCR instance for the whole sequence. + +The strict gate passed for both Private Bytes and Working Set. The 8K sample +was **148,996,096 / 152,911,872 B**; the immediately following 4K recovery +sample was **147,918,848 / 151,826,432 B** (**-1,077,248 / -1,085,440 B**). +The final 64x64 sample was **143,548,416 / 147,689,472 B**, only **0.25%** +above the warmed Private-Bytes baseline and below the pre-return high-water +mark. The complete per-resolution record is +`build/memory_ladder_medium_cpu_strict_final_20260814.json`. + +Reproduce it with: + +```powershell +python bench/generate_memory_ladder.py --output build/memory_ladder_images +python bench/memory_ladder_regression.py --cpp build/ppocr_mem_soak.exe --det D:/workprj/aicoder/.tmp/ocr-models/ppocrv6_medium_det.onnx --rec D:/workprj/aicoder/.tmp/ocr-models/ppocrv6_medium_rec.onnx --dict build/dict_ppocrv6_latin.txt --images build/memory_ladder_images --cycles 1 --backend cpu --require-post-large-decline --report build/memory_ladder_medium_cpu_strict.json +``` + +### 2026-08-14: current resolution-memory validation + +The reproducible ladder was generated again and run with one live medium CPU +OCR instance. It records Private Bytes and Working Set after every one of the +19 pages, with decoded PPM storage destroyed before each sample. The run +passed the bounded-return gate: + +| Checkpoint | Private Bytes | Working Set | +| --- | ---: | ---: | +| warmed baseline | 143,437,824 B | 閳?| +| 8K (`7680x4320`) | 148,480,000 B | 152,453,120 B | +| first 4K recovery | 148,000,768 B | 151,769,088 B | +| final `64x64` | 146,055,168 B | 150,097,920 B | + +Both counters fell immediately after 8K in this run; the final small image was +**1.82%** above the warmed private-byte baseline and below the complete +pre-return peak. The full per-resolution evidence, including the recovery +tail decision, is +`build/memory_ladder_medium_cpu_strict_current_20260814.json`. Results are +machine/run-specific process accounting, not a fixed cross-platform memory +guarantee. + +### 2026-08-14: revalidated varied-resolution memory recovery + +The 19-image ascending-and-recovery ladder was regenerated and rerun with one +medium PP-OCRv6 CPU instance (`PPOCR_BENCH_THREADS=16`). Each PPM is loaded, +recognized, destroyed, and only then sampled, so source RGB storage from a +large page cannot be hidden by retaining the input vector. The strict +post-large recovery gate passed for both Windows Private Bytes and Working Set: + +| Checkpoint | Private Bytes | Working Set | +| --- | ---: | ---: | +| warmed baseline | 142,888,960 B | n/a | +| 5K peak (`5120x2880`) | 148,463,616 B | 152,395,776 B | +| 8K (`7680x4320`) | 146,882,560 B | 151,015,424 B | +| first 4K recovery | 147,435,520 B | 151,506,944 B | +| final `64x64` | 146,251,776 B | 150,216,704 B | + +The observed peak was the 5K page rather than 8K, which is valid for Windows +process accounting and the detector's bounded tensor resize. Both counters +were already below that high-water mark at the first 4K recovery sample; the +final small image remained below it and was 2.35% above the warmed private-byte +baseline. The machine-specific, per-resolution JSON evidence is +`build/memory_ladder_medium_cpu_strict_revalidated_20260814.json`. + +### 2026-08-14: zero-copy top-level ONNX protobuf traversal + +Model construction no longer copies the complete embedded ONNX `GraphProto` +before parsing it. The model reader now exposes bounded protobuf byte spans; +the top-level graph is parsed directly from the already-owned model file buffer. +Nested node, attribute, initializer, and operator-set messages retain their +existing owning parse paths, so the supported PP-OCRv6 graph semantics and +runtime's no-ONNX-Runtime dependency remain unchanged. This removes one +transient full-model allocation/copy during startup and lowers model-loading +work without altering per-inference numerical operations. + +On the local Windows AVX-512 host (`PPOCR_BACKEND=cpu`, 16 kernel workers, +one warm-up and five English-page measurements), constructor-to-ready load +time changed as follows: + +| Model | Before | After | Lower load time | +| --- | ---: | ---: | ---: | +| tiny | 27.184 ms | 17.808 ms | 34.5% | +| small | 102.254 ms | 72.066 ms | 29.5% | +| medium | 519.523 ms | 294.587 ms | 43.3% | + +The per-model evidence is +`build/bench_model_load_span_parse_ab_20260814.json`; the post-change +inference snapshot is `build/bench_model_load_span_parse_20260814.json`. +Kernel and Vulkan admission smoke passed. CPU and hybrid also completed the +five-size `16x16`, English, low-contrast, ultra-wide, and ultra-tall corpus +for tiny/small/medium (30 successful executions per backend); the recorded +outputs are `build/smoke_span_parse_diverse_{cpu,hybrid}_20260814.json`. +One medium ultra-wide confidence differs only in the last reported digits in +hybrid because its transfer-inclusive channel-affine/depthwise-Swish admission +can select a numerically valid Vulkan segment; decoded text and geometry are +unchanged. GPU-only remains deliberately rejected until the complete graph is +device-resident. + +### 2026-08-14: invocation-local executor input scratch reuse + +Both the general graph executor and the production CTC executor now reuse one +invocation-local, non-owning node-input pointer vector. Previously, the general +path allocated a separate small vector at each generic operator and at several +in-place fast paths. The new scratch has eight reserved entries (larger future +operator signatures still grow it safely), is never shared across OCR calls, +and retains the existing no-TLS lifetime rule for MinGW worker teardown. + +This removes repeated allocator traffic without changing tensors, reduction +order, CPU SIMD dispatch, or the Vulkan admission policy. A fresh CPU English +snapshot (`PPOCR_BENCH_THREADS=16`, two warm-ups, twelve runs) measured +**30.817 / 61.215 / 182.730 ms** for tiny/small/medium. The varied-shape CPU +snapshot additionally completed ultra-wide at **19.090 / 44.437 / 127.590 ms** +and dense `1920x1080` at **265.831 / 1133.132 / 4880.140 ms** (three-run +shared-host samples, therefore directional rather than portability claims). + +The 19-resolution medium memory ladder passed again: its 5K high-water was +**149,815,296 / 153,812,992 B** (Private Bytes / Working Set), the first 4K +recovery was **146,288,640 / 150,216,704 B**, and final `64x64` was +**146,501,632 / 150,388,736 B**, still below the pre-return high-water. The +complete evidence is `build/memory_ladder_medium_cpu_input_scratch_reuse_20260814.json`. +All 15 tiny/small/medium varied-size cases completed in both CPU and hybrid; +their decoded text and geometry agree across backends. Kernel and Radeon 780M +Vulkan admission smokes passed, with channel-affine Swish and depthwise-Swish +still selected only when measured full-boundary GPU cost is no slower than CPU. +Records: `build/bench_input_scratch_reuse_{en,diverse}_20260814.json` and +`build/smoke_input_scratch_reuse_diverse_{cpu,hybrid}_20260814.json`. + +### 2026-08-14: small-to-large image memory recovery regression + +The repository includes a native process-memory regression for long-lived OCR +services. `bench/generate_memory_ladder.py` produces deterministic PPM pages +that increase from `16x16` through `7680x4320`, including wide and tall +aspect-ratio cases, then process a staged `4K -> 1080p -> wide/tall -> 64x64` +recovery tail. `bench/memory_ladder_regression.py` keeps one OCR instance alive +and records Windows Private Bytes and Working Set after every resolution. + +Run the full test with: + +```powershell +$env:PPOCR_BENCH_THREADS = '16' +python bench/generate_memory_ladder.py --output build/memory_ladder_images +python bench/memory_ladder_regression.py ` + --cpp build/ppocr_mem_soak.exe ` + --det D:/workprj/aicoder/.tmp/ocr-models/ppocrv6_medium_det.onnx ` + --rec D:/workprj/aicoder/.tmp/ocr-models/ppocrv6_medium_rec.onnx ` + --dict build/dict_ppocrv6_latin.txt ` + --images build/memory_ladder_images --cycles 1 --backend cpu ` + --require-post-large-decline ` + --report build/memory_ladder_medium_cpu_compact_uses_20260814.json +``` + +On the current Windows x86 host, the test passed after the compact executor +use-count change. The `7680x4320` sample reached **150,474,752 B / 154,353,664 +B** (Private Bytes / Working Set). The recovery tail fell to **147,111,936 B / +151,142,400 B** at `1920x1080`, and the final `64x64` checkpoint was +**148,066,304 B / 151,736,320 B**. Thus both counters declined below the +post-large high-water without restarting the OCR instance. The adjacent first +4K recovery measurement may briefly exceed the 8K sample because of Windows +allocator/working-set accounting; the enforced gate intentionally verifies a +decline in the complete post-large recovery tail instead of claiming a brittle +single-sample monotonic property. Full per-resolution evidence is +`build/memory_ladder_medium_cpu_compact_uses_20260814.json`. + +### 2026-08-14: refreshed exact detector batching across three model sizes + +The true same-shape detector NCHW batch was rerun after the memory work with +four copies of the English page. The check compares every text, quadrilateral, +bounding box, and confidence against four serial calls. Recognition retained +`rec_batch_size=1`: an investigation confirmed that forcing four recognizer +crops through the transformer can change exact CTC confidence on this host, so +it is not used for the exact-output benchmark. + +With `PPOCR_BENCH_THREADS=16`, `PPOCR_DET_BATCH_SIZE=4`, +`PPOCR_REC_BATCH_SIZE=1`, and `PPOCR_BATCH_PREPROCESS_PARALLELISM=4`, the +three-run means were: + +| Model | CPU serial | CPU batch | CPU speedup | Hybrid serial | Hybrid batch | Hybrid speedup | +| --- | ---: | ---: | ---: | ---: | ---: | ---: | +| tiny | 133.272 ms | 76.211 ms | 1.749x | 157.468 ms | 128.652 ms | 1.224x | +| small | 282.395 ms | 177.486 ms | 1.591x | 442.434 ms | 390.907 ms | 1.132x | +| medium | 1241.956 ms | 1013.146 ms | 1.226x | 1230.259 ms | 1138.408 ms | 1.081x | + +The corresponding exact-parity record is +`build/batch_detector_rec1_current_20260814.json`. Hybrid remains an +honest per-segment policy: Vulkan is selected only when the full measured +host-to-device, dispatch, and device-to-host boundary is no slower than CPU; +on this Radeon 780M run, small channel-affine Swish and depthwise-Swish +segments met that rule while the remainder correctly stayed on SIMD CPU. + +### 2026-08-14: verified four-page detector NCHW batching + +`RecognizeBatch()` was rechecked on four same-shape English pages for every +PP-OCRv6 tier. The detector receives one real `[4,3,H,W]` tensor; each +result, including text, quadrilateral, bounding box, and confidence, was +checked against four serial `Recognize()` calls by `ppocr_batch_smoke`. +Recognition remains `rec_batch_size=1` in this comparison: packing unequal +recognizer widths by right-padding changes transformer attention and can alter +CTC confidence, so it is not represented as exact-output acceleration. + +With 16 CPU workers, `det_batch_size=4`, four preprocessing workers, one +warm-up, and five measured CPU iterations, serial-to-batch time was: + +| Model | Serial mean | Batched mean | Throughput gain | +|---|---:|---:|---:| +| tiny | 146.914 ms | 86.413 ms | 1.700x | +| small | 318.376 ms | 204.255 ms | 1.559x | +| medium | 1289.731 ms | 1011.596 ms | 1.275x | + +The corresponding hybrid recheck (three iterations; the same exact-output +gate) measured **1.218x / 1.138x / 1.079x** for tiny/small/medium. Hybrid +still admits each Vulkan segment only after its complete H2D + shader + D2H +path is no slower than the matching CPU path; this is not a claim that the +incomplete full graph supports `gpu_only`. The host-specific full record is +`build/bench_batch_detector_nchw_current_20260814.json`. + +Reproduce the CPU measurement with: + +```powershell +$env:PPOCR_BACKEND='cpu'; $env:PPOCR_BENCH_THREADS='16' +$env:PPOCR_DET_BATCH_SIZE='4'; $env:PPOCR_REC_BATCH_SIZE='1' +$env:PPOCR_BATCH_PREPROCESS_PARALLELISM='4'; $env:PPOCR_BATCH_WARMUP='1'; $env:PPOCR_BATCH_RUNS='5' +.\build\ppocr_batch_smoke.exe DET.onnx REC.onnx dict.txt 1 en.ppm en.ppm en.ppm en.ppm +``` + +### 2026-08-13: Vulkan ConvTranspose + Add primitive groundwork + +The Vulkan backend now has a numerically tested `ConvTranspose(2x2, +stride=2) + equal-shape Add` primitive. It keeps the projection in device +buffer D, inserts a compute write/read barrier, adds the residual in a second +dispatch, and copies only the final sum back. Its hybrid admission is strict: +it measures and validates complete `H2D + two dispatches + fence + D2H` +against the matching CPU SIMD sequence, then selects Vulkan only when no +slower. + +On this Radeon 780M test shape (`N=4, Cin=32, Cout=40, 31x29`), GPU was +**2.771 ms** versus CPU **0.535 ms**, so CPU correctly remains selected. This +is backend coverage, not an end-to-end GPU speed claim. The current PP-OCRv6 +FPN export folds its following `[1,C,1,1]` Add into the transpose bias, so the +new equal-shape-residual primitive is intentionally not claimed as active for +that model revision. `ppocr_vulkan_smoke` covers it; tiny/small/medium CPU +text parity passed **2/2** each on `en.ppm` and `wide_strip_3000x80.ppm`, +recorded in `build/accuracy_{tiny,small,medium}_convtranspose_add_20260813.json`. + +## Build + +### 2026-08-14: compact execution liveness and resolution-memory revalidation + +The detector's generic executor now resets compact `uint16_t` use counters +indexed once at model load, rather than cloning a string-keyed use-count map +for every page. This removes per-inference hash-table bookkeeping while +retaining the existing last-use tensor release rules. The change applies only +to the fixed PP-OCRv6 graph topology; arbitrary graph values still retain +their original tensor ownership and output semantics. + +The CPU multi-size smoke completed tiny/small/medium over five distinct +shapes (`16x16`, English, ultra-wide, ultra-tall, and dense `1920x1080`). The +record is `build/bench_diverse_compact_uses_20260814.json`; its three-run +means are intentionally retained as per-host measurement evidence rather than +portable speed claims. Kernel and Radeon 780M Vulkan admission smokes also +passed. Hybrid retains its full transfer-inclusive rule: a Vulkan segment is +used only after measured `H2D + GPU + D2H` is no slower than the same CPU +segment. GPU-only remains deliberately rejected because the complete graph is +not yet device-resident. + +The 19-resolution medium CPU ladder was revalidated with one OCR instance +alive throughout. It passed `--require-post-large-decline`: the `7680x4320` +sample measured **147,972,096 B / 151,748,608 B** (Private Bytes / Working +Set), then the recovery tail reached **146,042,880 B / 148,320,256 B** at the +wide `4096x256` sample. The final `64x64` checkpoint was **147,783,680 B / +151,691,264 B**, below the largest-image private-byte value and below the +pre-return high-water. Full per-resolution evidence is +`build/memory_ladder_medium_cpu_compact_uses_final_20260814.json`. + +### 2026-08-14: current ascending-resolution memory regression + +The same long-lived medium CPU instance was rerun over all 19 generated +images, in ascending source sizes from `16x16` to `7680x4320`, followed by +`3840x2160 -> 1920x1080 -> 4096x256 -> 256x4096 -> 64x64`. Each page is +scoped to `load -> Recognize -> destroy -> sample`, so the measurements expose +both inference activation reuse and whether a decoded large source image stays +resident after its OCR call. + +The strict recovery gate passed. At 8K, Private Bytes / Working Set were +**148,131,840 B / 152,174,592 B**. The immediately following 4K page was +**147,681,280 B / 151,670,784 B**, a drop of **450,560 B / 503,808 B**. The +final `64x64` checkpoint was **147,587,072 B / 151,429,120 B**, below both the +8K sample and the pre-return high-water (**150,106,112 B / 154,062,848 B**), +without recreating the OCR instance. Per-resolution samples and the enforced +pass/fail decision are recorded in +`build/memory_ladder_medium_cpu_current_resolution_recovery_20260814.json`. + + +### 2026-08-14: refreshed three-tier CPU / Hybrid comparison + +`bench/compare.ps1` now accepts `-Backend cpu|hybrid|gpu` and passes the +choice through to the native benchmark. This makes the CPU and Hybrid runs +explicit in the same ONNX Runtime comparison harness instead of inheriting an +ambient process environment. + +On the local AVX-512 host, `en.ppm`, 2 warm-ups and 6 measured runs, the +native CPU implementation measured **32.315 ms** (tiny) and **67.419 ms** +(small), versus ONNX Runtime CPUExecutionProvider **113.453 ms** and +**149.804 ms**: **71.5%** and **55.0%** lower mean latency respectively. The +same harness measured medium Hybrid at **239.765 ms** versus ONNX Runtime +**333.395 ms** (**28.1%** lower). These are machine/run-specific samples; +reproduce before treating them as deployment guarantees. + +The medium high-density `dense_blobs` stress bound was refreshed to +`[100, 3600]`. The current native medium detector produced 2,903 valid +components and the full 11-image varied-size stress suite passed. + +### 2026-08-14: terminal CTC projection is now the default + +The recognizer's final vocabulary projection is now executed through the +bounded `GemmCtcTop1` route by default. It computes each small time-step tile, +performs the CTC argmax/probability reduction, and releases that tile rather +than materializing the full `[N,T,V]` logit tensor. Set +`PPOCR_DISABLE_FUSED_TERMINAL_CTC=1` only for an A/B comparison with the older +materialized-logit route. + +On the dense `ui_dense_1920x1080` corpus the default route reduced measured +CPU latency in this local run from **279.538 to 263.995 ms** for tiny +(123 crops), **1077.122 to 965.587 ms** for small (119 crops), and +**6285.383 to 5621.346 ms** for medium (122 crops). These samples are +machine-specific; text parity against ONNX Runtime passed 4/4 varied inputs +for each model after enabling the default. + +### 2026-08-14: refreshed 16x16-to-8K memory recovery measurement + +The deterministic 19-image ladder was rerun with one live medium CPU OCR +instance. It processes ascending source resolutions from `16x16` through +`7680x4320`, then a `3840x2160 -> 1920x1080 -> 4096x256 -> 256x4096 -> +64x64` recovery tail. Every input is scoped to `load -> Recognize -> destroy +-> sample`, so this measures both activation reuse and release of a large +decoded RGB source image. + +The strict post-large recovery gate passed. The 5K/8K high-water was +**150,675,456 B / 154,615,808 B** (Private Bytes / Working Set); the first +4K recovery sample was **150,036,480 B / 154,087,424 B**, and the final +`64x64` sample was **148,877,312 B / 151,830,528 B**. The final small-image +footprint was 3.63% above the warmed private-byte baseline and below both +pre-return peaks, confirming bounded memory recovery without recreating the +OCR instance. Full per-resolution evidence is +`build/memory_ladder_medium_cpu_post_large_20260814.json`. Windows allocator +accounting may fluctuate between adjacent samples; the enforced condition is +that both counters return below the 5K/8K high-water somewhere in the +post-large recovery tail. +### 2026-08-14: CTC tile-policy validation and final memory recheck + +The four-row bounded terminal-CTC projection remains the default. An +experimental automatic eight-row choice for the wider recognizers was tested +on the high-density `1920x1080` sample, but was slower in the paired local +runs: small measured **914.427 ms** versus **897.369 ms** with four rows, and +medium measured **4829.971 ms** versus **4529.301 ms**. The larger tile +remains available only through `PPOCR_FUSED_TERMINAL_CTC_TILE_ROWS` for +platform-specific experiments; it is not used as the portable default. + +After this decision, the complete 19-resolution medium CPU memory check +passed again. Private Bytes / Working Set fell from **147,623,936 B / +151,322,624 B** at the 8K sample to **146,046,976 B / 149,807,104 B** at the +first 4K recovery; final `64x64` was **143,917,056 B / 147,906,560 B** +(**0.04%** above the warmed private-byte baseline), below the full pre-return +high-water. The durable per-resolution record is +`build/memory_ladder_medium_cpu_tile4_20260814.json`. +### 2026-08-14: recognizer hotspot profiling and Vulkan Hybrid revalidation + +`PPOCR_PROFILE=1` now reports the terminal-CTC executor even when its fused +`GemmCtcTop1` path returns early. On the medium ultra-wide crop, that direct +measurement identifies the terminal vocabulary projection as the largest +recognizer operation (**40.456 ms** in this local profile), followed by the +existing fused 1x1/residual convolutions. This makes future optimization work +measurable instead of inferring recognizer cost from detector-only profiles. + +The Vulkan Hybrid policy was revalidated on AMD Radeon 780M. It measures each +implemented segment as a complete synchronous `H2D + dispatch + D2H` path and +selects GPU on `gpu_mean <= cpu_mean`; smoke selected GPU for channel-affine +Swish (**0.193 vs 0.404 ms**) and depthwise-Swish (**0.341 vs 0.346 ms**), +while transfer-bound primitives correctly remained on CPU. Tiny, small, and +medium Hybrid text parity all passed on normal and ultra-wide inputs (6/6). +GPU-only remains deliberately unavailable until the complete detector, +recognizer, and post-processing graph is device-resident; it does not silently +fall back to CPU. + +The AVX-512 four-row GEMM microkernel was also retested against the stable +two-row default. It remains an explicit +`PPOCR_ENABLE_AVX512_GEMM4ROW=1` deployment A/B option only: its effect varied +between otherwise similar paired runs, so it is not enabled by default. + +### 2026-08-14: medium terminal-CTC projection parallelism + +The terminal CTC projection now uses a bounded **32-row** vocabulary tile for +the medium recognizer (`depth >= 384`, `vocab >= 1024`); tiny and small retain +the prior four-row tile. This gives a single ultra-wide medium crop enough +independent GEMM rows to use the persistent SIMD pool, while keeping CTC +blank/repeat state serial in time order and the workspace bounded. The +`PPOCR_FUSED_TERMINAL_CTC_TILE_ROWS=1|2|4|8|16|32` override remains available +for deployment-side A/B. + +On this AVX-512 Windows host (16 workers), paired ultra-wide `3000x80` +measurements improved medium from **189.408 ms** (four rows) to **150.969 ms** +(32 rows), a **20.3%** reduction; small improved from **61.882 to 56.759 ms** +in that isolated wide test, but dense-page runs were less stable, so its +conservative default remains four rows. Medium dense `1920x1080` also improved +from **5237.145 to 4671.601 ms** in the paired run. These figures are local +host measurements, not portable latency guarantees. + +The associated 19-resolution medium CPU memory gate passed: 8K was +**150,437,888 B / 154,501,120 B** (Private Bytes / Working Set), immediate +4K recovery was **148,398,080 B / 152,215,552 B**, and final `64x64` was +**144,076,800 B / 148,070,400 B**, below baseline and all large-page +high-water marks. Per-resolution evidence: +`build/memory_ladder_medium_cpu_ctc32_20260814.json`. + +The same gate was rerun after the final CTC policy validation. It again +passed the enforced `--require-post-large-decline` condition: the 5K/8K +high-water was **149,454,848 B / 153,169,920 B**, the first post-8K 4K page +fell to **146,534,400 B / 150,233,088 B**, and the final `64x64` checkpoint +was **147,755,008 B / 151,703,552 B**. This is **0.37%** above the warmed +**147,210,240 B** private-byte baseline and below both pre-return peaks, so +large decoded images and inference workspaces do not remain pinned after the +large-image sequence. The ladder deliberately covers 19 inputs from `16x16` +through `7680x4320`, including wide/tall aspect-ratio branches and a staged +`4K -> 1080p -> wide -> tall -> 64x64` recovery tail. Full JSON evidence: +`build/memory_ladder_medium_cpu_ctc32_recheck_20260814.json`. + +### 2026-08-14: CTC workspace reuse experiment rejected + +A CTC vocabulary-tile reuse experiment was measured on the 123/119/122-crop +dense `1920x1080` page. Sharing one preallocated tile per in-flight sequence +increased the medium batch workspace enough to cause a memory-recovery gate +failure on one fresh run, while its latency did not improve reliably. The +production implementation therefore retains a short-lived, per-worker bounded +tile: it has a strict `32 * vocab`-float cap for medium and `4 * vocab` for +tiny/small, releases promptly after each recognition task, and avoids unsafe +MinGW thread-local destructors. This choice is deliberately evidence-led: the +restored implementation passed the 19-resolution CPU memory gate again, with +the first recovery-tail point below the 8K private/working-set high-water at +`1920x1080` (**146,456,576 B / 149,090,304 B**) and final `64x64` still below +the pre-return peak. Evidence: +`build/memory_ladder_medium_cpu_ctc_workspace_reverted_20260814.json`. + +### 2026-08-14: hardware-aware recognition worker bound + +The 12-way CPU recognition default is capped at +`std::thread::hardware_concurrency()`. This retains the measured 12-way +policy on the local 16-logical-core AVX-512 machine while preventing a small +x86 or ARM target from constructing more independent crop graphs than its +available logical CPUs. Hybrid deliberately keeps its separate +`hybrid_graph_parallelism` policy because its Vulkan queue is serialized. The +public `PPOCR_REC_PARALLELISM` override remains available for host-specific +tuning. + +### 2026-08-14: dense-page recognition scheduler tuning + +The CPU default `rec_parallelism` is now **12** (override with +`PPOCR_REC_PARALLELISM`). A 16-worker AVX-512 sweep on the 123/119/122-crop +dense `1920x1080` page measured 8-way versus 12-way versus 16-way outer +recognition scheduling. Twelve was the stable cross-model choice: tiny +improved from **282.675 to 241.928 ms** (14.4%), small from **949.373 to +**885.617 ms** (6.7%), and medium from **3968.286 to 3905.875 ms** (1.6%). +At 16 ways medium regressed to **4375.612 ms**, so the default deliberately +leaves headroom for its larger SIMD kernels and avoids multiplying dense-page +activation lifetime further. + +A fresh default run measured **236.679 / 854.346 / 4136.895 ms** for +tiny/small/medium respectively (3/3, 3/3, and 2/2 measured samples). Normal +and ultra-wide decoded-text parity against ORT remained 6/6. The 19-resolution +medium memory gate also passed: after the 8K page, Private Bytes / Working +Set fell from **149,106,688 / 153,096,192 B** to **147,845,120 / +151,638,016 B** at the first 4K recovery page; the final `64x64` checkpoint +remained below the large-page high-water. Evidence: +`build/memory_ladder_medium_cpu_recparallel12_20260814.json`. + +### 2026-08-14: multi-image native/ORT gate repair and revalidation + +`bench/compare_models.ps1` now reliably expands a comma-separated or native +PowerShell `string[]` image list, forwards the selected CPU/Hybrid backend, +and distinguishes a latency-weighted corpus gate from an explicit per-case +floor. This prevents a one-image invocation from being presented as a +multi-resolution result and makes each model/image pair independently auditable. + +A fresh CPU validation used normal English and ultra-wide `3000x80` text, +16 workers, one warm-up, two timed runs, and required every one of the six +model/image pairs to beat ONNX Runtime CPU. All passed. The latency-weighted +native reductions were **68.1%** (tiny), **56.2%** (small), and **22.9%** +(medium); no model had a losing case in this run. Full machine-specific +evidence: `build/compare_models_cpu_normal_wide_gate_20260814.json`. + +The same wrapper also supports `-Backend hybrid`; on this Radeon 780M UMA +host, it preserves the transfer-inclusive Vulkan admission policy rather than +claiming universal end-to-end GPU gains. + +### 2026-08-14: refreshed three-tier ONNX Runtime comparison + +The current 16-worker CPU comparison (2 warm-ups, 6 measured `en.ppm` runs) +continues to show substantial native gains over ONNX Runtime CPUExecutionProvider: +**33.084 vs 118.015 ms** for tiny (**72.0% lower**), **72.522 vs 195.894 ms** +for small (**63.0% lower**), and **222.385 vs 402.871 ms** for medium +(**44.8% lower**). These are paired local-host measurements and include the +complete native OCR pipeline, not an isolated kernel claim. + +An additional selected-class CTC-softmax parallelization experiment was +rejected: it was neutral on a single wide crop and slower on a dense medium +page, so the shipped path retains the lower-variance temporal CTC scan. +Hybrid text parity was rerun for tiny/small/medium on normal and ultra-wide +inputs (6/6); the GPU decision rule remains unchanged: choose Vulkan only +when the complete transfer-inclusive segment is no slower than CPU. + +### 2026-08-14: Vulkan device-resident graph foundation + +The Vulkan backend now has a `VulkanTensorArena` separate from Hybrid's five +short-lived scratch bindings. It allocates FP32 storage slots by tensor size, +reuses a released slot only after the caller's final-use decision, and reports +live versus retained capacity. Graph boundaries can upload inputs/constants +and download requested outputs, while intermediate elementwise values remain +in Vulkan buffers. The first device-resident operators are exact binary +in-place updates and the NCHW 1x1 Conv family used throughout the recognizer; +both insert compute write-to-read barriers before their output can feed the +next graph node. + +The Radeon 780M Vulkan smoke now verifies slot allocation/reuse, upload, +device binary and dependent binary-chain execution, plus device-resident +pointwise convolution against CPU FP32 reference values. The regular SIMD and +all existing Hybrid primitives remain covered. This is infrastructure for the +complete GPU-only graph, not a claim that `gpu_only` is available yet: pool, +LayerNorm, attention Softmax/QKV, transposes, concatenation, detector DB +post-processing, and remaining graph dispatches still need device paths. + +### 2026-08-14: GPU-only graph operator expansion + +The device arena now additionally supports a real destination-writing NCHW +suffix broadcast (`[N,C,H,W]` with compact `[C,1,1]` coefficients) and exact +Erf-form GELU on the shader. Both are numerically checked by +`ppocr_vulkan_smoke` on the AMD Radeon 780M; neither reads an intermediate +activation back through the CPU. The broadcast form is required for SE gates +and compact graph scale paths, while exact GELU covers a fused-model operator +present in every supported detector/recognizer pair. + +This does **not** enable `--backend gpu`: the complete graph still lacks +device implementations for graph concatenation/shape-slice metadata handling, +unfused resize forms, SE composition, and the full OCR image/DB/CTC pipeline. +Construction continues to fail explicitly rather than silently executing an +activation on CPU. No end-to-end GPU-only benchmark is recorded until that +contract can be exercised and compared fairly. + +The same arena now includes device-resident two-to-four input `Concat` and +integer-factor asymmetric/floor nearest `Resize` (including unequal height / +width factors). These are validated with multi-outer-block and `N=2` smoke +cases. They remove two more detector-FPN activation boundaries; they do not +change the strict GPU-only availability gate because a complete model graph +and OCR front/back-end still require verified device dispatches. + +Medium-model SE is now represented as one device-resident arena routine: +spatial mean, both 1x1 projections, ReLU, HardSigmoid, and final channel +multiply all remain in Vulkan buffers. The Radeon smoke checks every output +against an independent FP32 reference for `N=2,C=4,reduced-C=3,plane=13`. + +The ONNX executor now also has a strict Vulkan graph-execution scaffold with +device value metadata, graph-use-count slot reclamation, device copy for +branch fan-out, metadata-only reshape/squeeze/unsqueeze, pointwise unary and +binary aliases, Concat, and fused SE routing. It returns failure immediately +on an uncovered graph node; the public GPU-only gate remains closed until the +entire detector, recognizer, and OCR pipeline can use that path. + +The strict graph executor now maps normal/fused NCHW Conv and Max/AveragePool +to their device-arena implementations. When an activation fan-out prevents an +in-place update, it first uses the new GPU copy primitive; this preserves +graph arithmetic rather than overwriting a still-live branch. Unsupported +geometry or nodes still terminate GPU-only execution instead of invoking CPU. + +### 2026-08-15: strict Vulkan graph coverage extended + +The strict device graph now also covers detector depthwise/pointwise blocks, +residual 1x1 projections, compact SE-style broadcasts, spatial means, +integer nearest resize and resize-add, 2x2 stride-two transpose convolution, +SAME padding for Conv/Pool, inference BatchNorm channel-affine, rank 2--4 +transpose, and final matrix projection/Softmax. `FusedConvHardSigmoid` was +corrected to run its exported alpha/beta activation as a separate Vulkan unary +after convolution; it no longer risks returning an ungated Conv result. + +`ppocr_gpu_graph_smoke` was added as a direct CPU-versus-strict-device graph +tool. It deliberately does not mark public `gpu_only` OCR as available: the +full image preprocessing, DB detector postprocessing, crop generation and +CTC decoding must still be moved onto Vulkan before that user-facing contract +can be truthfully enabled. On 2026-08-15 the Radeon 780M low-level Vulkan and +SIMD smoke suites passed; full-graph parity is still gated while the remaining +recognizer attention nodes and final numerical-error envelope are completed. + +### 2026-08-15: GPU-only recognizer scheduling progress + +The strict Vulkan executor now runs the PP-OCRv6 small/medium recognizer's +dynamic shape-metadata chains (`Shape`/`Slice`/`Squeeze`/`Unsqueeze`/`Concat`), +scalar attention scale, fused QKV split, rank-3/rank-4 attention `MatMul`, +Softmax, and residual transformer blocks without downloading an activation. +Only integer shape descriptors are interpreted on the host; feature maps stay +in arena buffers. The generic GEMM path is the current correctness baseline; +the experimental tiled GEMM requires `PPOCR_ENABLE_VULKAN_GEMM_TILE=1`. + +Verification on the AMD Radeon 780M: `ppocr_vulkan_smoke` and +`ppocr_kernel_smoke` pass, and the normal tiny Hybrid OCR benchmark remained +functional at **10.775 ms** mean over two measured runs on `line_en.ppm`. +The ordinary-Conv shared-memory route is now gated by the same large-output +threshold in host dispatch and shader dispatch. Previously a compact SE gate +could be launched through the generic host geometry but interpreted as a +channel-tiled shader geometry, leaving stale arena values. With that mismatch +removed, strict CPU-versus-Vulkan forward parity now passes for every shipped +network on the Radeon 780M: tiny/small/medium detector at `1x3x960x960`, and +tiny/small/medium recognizer at `1x3x48x320`. The largest observed final +absolute errors are `2.42644e-06`, `6.57933e-06`, and `7.00675e-09` for the +detectors, and `5.88894e-05`, `2.09391e-04`, and `8.39829e-05` for the +recognizers, respectively. + +`ppocr_gpu_graph_smoke` now accepts an optional `RUNS` argument and prints +CPU/GPU graph means, including the current GPU graph boundary. The initial +two-run reference on this UMA Radeon machine measured tiny detector +`124.284 / 610.187 ms`, tiny recognizer `8.190 / 173.200 ms`, small detector +`219.862 / 1613.830 ms`, small recognizer `20.697 / 370.361 ms`, medium +detector `1033.580 / 8530.580 ms`, and medium recognizer `33.085 / 577.311 +ms` (CPU / strict Vulkan). These are correctness-baseline measurements, not +a GPU speed claim: each current graph operator submits and waits separately, +so command-batch compilation and persistent model constants are the next +Vulkan performance work. + +### 2026-08-15: strict graph single-submit command recording + +The strict neural Vulkan executor now records a complete forward graph into +one command buffer and waits only at its output boundary. Every dispatch gets +an immutable descriptor set from a dedicated resettable graph pool, preventing +later descriptor writes from changing earlier recorded bindings. Hybrid keeps +its original synchronous descriptor pool and full-boundary admission policy. + +The local Radeon 780M verification passed the Vulkan primitive suite, SIMD +kernel suite, and all six strict graph parity cases at the published shapes. +The current two-run CPU / Vulkan means are tiny detector **223.271 / 1042.440 +ms**, tiny recognizer **29.517 / 319.981 ms**, small detector **195.110 / +1249.390 ms**, small recognizer **18.378 / 291.485 ms**, medium detector +**812.492 / 10669.200 ms**, and medium recognizer **39.293 / 564.885 ms**. +Final tensor parity was exact in these runs (max absolute error `0`). The UMA +driver still makes this graph implementation slower than the AVX-512 CPU +baseline; eliminating submission fences alone is not enough to claim a +speedup, so the public GPU-only OCR contract remains closed. + +### 2026-08-15: persistent GPU model weights and lower Conv tile threshold + +Strict `OnnxLite` GPU models now retain their immutable initializer slots in a +model-owned Vulkan arena. Activations are released after every successful or +failed run, and the arena is guarded for the complete graph recording; this +removes repeated model-weight allocation/upload and prevents per-inference +arena growth. The ordinary-Conv shared-filter tile threshold was lowered from +16,384 to 4,096 output pixels in both host and shader dispatch logic, while +retaining the compact SE fallback path. + +With a warmed model, Radeon 780M three-run strict graph means were **tiny +detector 111.399 / 264.214 ms**, **small detector 229.969 / 858.226 ms**, +**medium detector 820.237 / 8059.020 ms** (medium: two runs), **tiny +recognizer 7.915 / 86.976 ms**, **small recognizer 18.101 / 122.982 ms**, and +**medium recognizer 34.873 / 354.897 ms** (CPU / Vulkan). Exact parity held +for all six models. The tiny detector resolution ladder also passed at +`320²`, `640²`, and `960²` with zero final error; warmed Vulkan means were +**40.471**, **109.382**, and **264.214 ms**, respectively. A real `N=4` +tiny-recognizer batch at `4x3x48x320` also remained exactly equal to CPU. + +These results are a substantial reduction of strict-device scheduling and +weight-transfer overhead, but this Radeon 780M UMA configuration is still not +faster than its AVX-512 CPU path for complete PP-OCRv6 graphs. Hybrid retains +its measured per-segment policy: when Vulkan is equal or faster for the full +boundary it is selected, otherwise CPU is retained to avoid consuming GPU +time without a latency benefit. + +### 2026-08-15: expanded Conv tile range + +The ordinary-Conv shared-weight tile is now eligible from a `256`-pixel +output plane (host and SPIR-V use the same gate), extending reuse to smaller +detector feature maps without changing compact SE convolutions. The regenerated +shader and strict graph test passed with final error `0` on tiny detector +`320x320` and `960x960`; warmed Vulkan means were **37.13 ms** and +**236.52 ms**, respectively. Lowering the threshold again to `64` regressed +both shapes, so `256` is retained. + +### 2026-08-15: GPU-only front/back-end groundwork + +The Vulkan arena now has a live-slot graph handoff API, fused BatchNorm+Swish +dispatch, RGB bilinear-resize+NCHW-normalization shader, device threshold-mask +shader, and device CTC Top-1 reduction. `ppocr_gpu_frontend_smoke` verifies +the RGB path on Radeon 780M; its maximum detector-normalized difference from +the scalar front-end was **0.0175072**, below one source uint8 normalization +step. The strict tiny detector and recognizer graph regressions remained exact +at their final tensors. + +This is deliberately not advertised as a completed public GPU-only OCR mode: +DB box scores/unclip parity and whole-image decoded-text parity still require +an end-to-end validation suite. Accordingly `Backend::gpu_only` continues to +fail explicitly rather than returning potentially different OCR results. The +experimental device orchestration never falls back to the CPU NN executor, +but it is not enabled through the public API until that parity evidence exists. + +### 2026-08-15: strict graph memory ladder and default recognizer GEMM tile + +`ppocr_gpu_graph_mem_soak` is a new model-level Vulkan memory regression tool. +It warms one model, drives it through an ascending resolution/batch ladder, +then repeats a small input and reports both allocated arena capacity and live +bytes. Capacity is deliberately reusable high-water storage; the required +invariant is that live bytes return to the model's persistent-weights baseline +after every run. + +On the Radeon 780M, tiny detector `320x320 -> 640x640 -> 960x960 -> 320x320` +grew capacity to **214,007,808 bytes** while live bytes returned after every +sample to **1,713,620 bytes**. Tiny recognizer +`1x3x48x80 -> 1x3x48x320 -> 4x3x48x320 -> 8x3x48x640 -> 1x3x48x80` reached +**67,633,152 bytes** and recovered each time to **4,417,112 bytes**. The +same invariant passed on small detector (**303,267,840 / 9,813,412 bytes**) +and medium recognizer (**191,889,408 / 76,456,032 bytes** capacity/live +baseline). This explicitly covers both varied detector images and recognition +batch/width growth without retaining dynamic activations after a large run. + +The verified non-Swish strict-graph GEMM tile is now default-enabled for +`rows >= 8, depth >= 16, columns >= 128`; set +`PPOCR_DISABLE_VULKAN_GEMM_TILE=1` for an A/B fallback. On the same host, +final tensor parity remained exactly zero for all three recognizers. The +current short strict-recognizer means at `1x3x48x320` were tiny +**9.869 / 37.195 ms**, small **23.498 / 107.000 ms**, and medium +**45.271 / 389.620 ms** (CPU / Vulkan). This is an improvement for the +device graph but not a claim that this AVX-512 + Radeon 780M UMA system beats +CPU or ONNX Runtime end-to-end; Hybrid still uses its full-boundary +no-slower admission rule. + +### 2026-08-15: parallel Softmax writeback + +The strict Vulkan Softmax now retains its sequential max/sum reduction for +numerical stability, then spreads the independent exponential/writeback stage +across the 256-lane workgroup. This removes a serial device loop in +recognizer attention and terminal class Softmax without adding an activation +allocation. Final tensor parity remained **0** for tiny, small, and medium +recognizers at `1x3x48x320`, and at a real `4x3x48x320` batch. The short +post-change means were tiny **37.470 ms**, small **94.376 ms**, and medium +**382.981 ms** for the single-crop strict Vulkan graph; the small recognizer +improved from the preceding **107.000 ms** sample. Device output is still +slower than the local AVX-512 CPU baseline, so this is a verified incremental +improvement rather than an ONNX Runtime superiority claim. + +The public `gpu_only` OCR switch remains deliberately disabled. Image resize +and normalization upload, DB connected-component/unclip postprocessing, crop +generation, CTC top-1/decode, end-to-end output parity, and memory recovery +must be completed before the public contract can truthfully promise complete +GPU-only OCR. + +### 2026-08-15: device-resident OCR path validation gate + +The experimental OCR route now feeds strict Vulkan detector/recognizer graphs +from the fused Vulkan RGB resize, BGR conversion and normalization dispatch; +it no longer builds detector or recognizer NCHW activations with CPU floating +point code. Detector probabilities are downloaded for the existing DB +connected-component/score/unclip control path, and only compact CTC Top-1 +metadata is downloaded for string assembly. `ppocr_gpu_ocr_smoke` compares +the public OCR result (text, quad, bounding rectangle and confidence) with +CPU-only OCR. + +On the Radeon 780M, tiny and small models passed `en.ppm`, `line_en.ppm` and +`mixed.ppm` (6 decoded regions each), with maximum confidence differences +of **0.0000061** and **0.0000019**, respectively. Tiny also passed `en.ppm` +alone at **0.0000026**. These runs establish that the NN graph has no silent +CPU operator fallback, but do not establish complete release coverage: +the dense 1920x1080 page diverged in detector/recognizer results (tiny result +72; small result 16), and medium detector strict submission at its real +`1x3x160x704` shape produced an all-zero probability map (while its 128x704 +pipeline smoke passed). Therefore `full_graph_gpu_available` deliberately +remains false and `Backend::gpu_only` continues to reject construction. This +is a correctness gate, not a performance claim; no ONNX Runtime comparison or +superiority is asserted for the incomplete GPU-only route. + +### 2026-08-15: GPU-only completion status + +The implementation now has an all-device neural graph path, fused RGB-to-NCHW +front end, device CTC Top-1 and no CPU floating-point inference fallback. +However, it is still an experimental path rather than the requested released +GPU-only mode: on the Radeon 780M, the medium detector's true +`1x3x160x704` graph still returns `VK_ERROR_DEVICE_LOST` at the final +896-channel `5x22` depthwise block, even with one-node submissions. The +standalone arena regression for that exact depthwise geometry passes, which +isolates the remaining defect to full-graph/resource interaction. In addition, +the existing DB connected-component/unclip geometry stage remains CPU control +code, and dense `1920x1080` OCR parity is not yet exact. The public gate is +therefore intentionally still closed; advertising it as complete GPU-only +inference would be incorrect. + +### 2026-08-15: GPU-only revalidation (current workspace) + +The strict Vulkan implementation was rebuilt after repairing the source file +and revalidated on **AMD Radeon 780M Graphics** with +`PPOCR_GPU_ONLY_SEGMENT_NODES=1`. It remains a no-CPU-fallback neural graph +path, but the public `Backend::gpu_only` gate is still intentionally false. +The following current CPU-versus-device graph checks passed: + +| Model | Shape | Max absolute output error | CPU mean | Vulkan mean | +|---|---:|---:|---:|---:| +| tiny detector | `1x3x160x704` | `4.83182e-07` | 28.844 ms | 224.343 ms | +| small detector | `1x3x160x704` | `1.91038e-07` | 41.481 ms | 301.020 ms | +| medium recognizer | `1x3x48x320` | `8.39829e-05` | 60.583 ms | 552.145 ms | + +The Vulkan primitive suite also passes, including the standalone +`C=896,H=5,W=22` depthwise convolution that resembles the medium detector +terminal block. The remaining release blocker is reproducible only in the +complete medium detector graph: `ppocrv6_medium_det.onnx` at +`1x3x160x704` loses the Radeon device (`VK_ERROR_DEVICE_LOST`) even with one +node per command-buffer submission. This makes public GPU-only OCR unsafe; +therefore no ONNX Runtime performance-superiority claim is made. + +`ppocr_gpu_graph_mem_soak` now provides a device-arena recovery check. On the +tiny detector, its `1x3x64x128 -> 1x3x96x256 -> 1x3x128x512 -> 1x3x64x128` +run grew reusable capacity from 18,874,368 to 27,721,728 bytes, while live +bytes returned after **every** sample to the 1,713,668-byte immutable-model +baseline. Capacity is intentionally retained for reuse; recovered live bytes +are the leak/lifetime invariant. +## Model files + +Get `ocr-models.zip` from the MaClaw `Model_Release` and unpack it. Pass a +matching detector, recognizer, and dictionary. The small/medium dictionary +is `D:\workprj\aicoder\corelib\ocr\dict_ppocrv6.txt`; the model archive +contains `dict_ppocrv6_tiny.txt` for the tiny recognizer. + +## Demo + +The included demo uses binary P6 PPM to avoid coupling a specific image +decoder to the inference library: + +```powershell +.\build\ppocr_demo.exe ppocrv6_tiny_det.onnx ppocrv6_tiny_rec.onnx dict_ppocrv6_tiny.txt image.ppm +``` + +For PNG/JPEG/BMP, decode with the host application's existing image library +and construct `ppocr::Image { width, height, packed_rgb }` before calling +`ppocr::OCR::Recognize`. + +## Scope + +The C++ pipeline contains PP-OCRv6 BGR preprocessing, dynamic detection and +recognition sizing, CTC greedy decoding, and DB-style threshold/score/unclip +text region extraction. Its ONNX reader accepts the standard embedded +float/int initializers used by the official model bundle; it intentionally +does not support arbitrary ONNX graphs, custom operators, or external tensor +data. + +### 2026-08-15: strict GPU-only execution revalidation + +The strict Vulkan graph executor now uses a device-resident submission boundary +per graph node by default. This is a GPU-to-GPU synchronization boundary: model +constants and live activations remain in `VulkanTensorArena`, and there is no +CPU operator fallback. A compact, separate depthwise SPIR-V pipeline is used +for narrow high-channel feature maps, avoiding the monolithic-shader tail on +Radeon UMA hardware. + +On AMD Radeon 780M, CPU versus strict GPU graph checks passed for: + +| Model | Shape | Max absolute output error | CPU mean | Vulkan mean | +|---|---:|---:|---:|---:| +| tiny detector | `1x3x160x704` | `4.83182e-07` | 22.184 ms | 113.042 ms | +| small detector | `1x3x160x704` | `1.91038e-07` | 42.603 ms | 193.311 ms | +| medium detector | `1x3x160x704` | `6.56222e-04` | 128.313 ms | 757.807 ms | +| medium recognizer | `1x3x48x320` | `8.39829e-05` | 39.960 ms | 472.034 ms | + +The medium detector memory ladder (`64x128 → 96x256 → 128x512 → 160x704 → +64x128`) also passed: its grow-only arena reached `291,667,968` bytes, while +live allocation returned after every run to the immutable-model baseline of +`61,946,548` bytes. + +Public `Backend::gpu_only` remains deliberately unavailable. Tiny and small +completed end-to-end CPU/GPU OCR parity on `en.ppm` (maximum confidence errors +`0.0000029` and `0.0000001`); however, a real-image medium detector input still +reproducibly produces `VK_ERROR_DEVICE_LOST` on this Radeon 780M at the final +896-channel depthwise layer. The same graph succeeds with the deterministic +regression tensor, therefore this is a driver/input-specific reliability +failure rather than an unsupported ONNX operator. Enabling the public API until +that real-image path is stable would violate the requested correct inference +contract. The measured Vulkan route is also slower than the AVX-512 CPU on this +integrated GPU, so no superiority claim is made. + +### 2026-08-15: GPU-only arena lifetime and current recheck + +Strict Vulkan graph segments now close only after their final input consumers +have been retired. The following segment opens lazily, after the completed +fence, so released activation buffers are eligible for arena reuse immediately. +This is a device-to-device scheduling/lifetime change: no activation is +downloaded, re-uploaded, or evaluated by the CPU. + +Current Radeon 780M checks with `PPOCR_GPU_ONLY_SEGMENT_NODES=1`: + +| Model | Shape | Max absolute output error | CPU mean | Vulkan mean | +|---|---:|---:|---:|---:| +| tiny detector | `1x3x160x704` | `4.83182e-07` | 19.293 ms | 100.492 ms | +| small detector | `1x3x160x704` | `1.91038e-07` | 29.877 ms | 187.476 ms | +| medium detector | `1x3x128x704` | `7.48696e-09` | 85.258 ms | 716.522 ms | +| medium recognizer | `1x3x48x320` | `8.39829e-05` | 40.103 ms | 481.122 ms | + +The tiny-detector device memory ladder +`64x128 -> 96x256 -> 128x512 -> 64x128` recovered to its +`1,713,668`-byte immutable-constant baseline after every sample. Reusable +capacity grew from `18,874,368` to `27,525,120` bytes and remained stable on +the final small input. + +The real medium detector at `1x3x160x704` still loses the Radeon device at +`p2o.pd_op.depthwise_conv2d.12.0` (`896x5x22`, `VK_ERROR_DEVICE_LOST`), even +with one device-resident node per fenced submission and isolated GPU copies. +Therefore `full_graph_gpu_available` remains false: enabling the public +`gpu_only` API would advertise a mode that is not correct on the tested +hardware. These measurements also show that this strict implementation is +not yet faster than the local AVX-512 CPU, so the README makes no GPU or ONNX +Runtime superiority claim. + +`PPOCR_GPU_ARENA_RETAIN_MB` is available for deployment diagnosis of the +device arena. Its default is `128` MiB; `0` retires every completed free +activation allocation between fenced GPU segments without touching live +values or immutable model constants. It did not resolve the Radeon medium +`160x704` driver reset, so it is a memory-pressure control rather than a +claim of GPU-only completion. + +### 2026-08-15: GPU-only reliability status (latest) + +The strict Vulkan graph remains fully device-resident between its input and +output boundaries: all PP-OCRv6 neural operators execute in Vulkan buffers, +and failure is reported rather than silently executing a CPU operator. The +experimental generated `vulkan_depthwise_tail.comp` route was removed because +the runtime was still bound to the established checked-in depthwise SPIR-V +module; retaining an unused second shader would make qualification results +ambiguous. + +Current Radeon 780M verification with `PPOCR_GPU_ONLY_SEGMENT_NODES=1`: + +| Model | Shape | Max absolute output error | CPU mean | Vulkan mean | +|---|---:|---:|---:|---:| +| tiny detector | `1x3x160x704` | `4.83182e-07` | 21.400 ms | 103.202 ms | +| small detector | `1x3x160x704` | `1.91038e-07` | 35.271 ms | 182.782 ms | +| medium detector | `1x3x128x704` | `7.32689e-09` | 103.195 ms | 779.817 ms | +| medium recognizer | `1x3x48x320` | `8.43406e-05` | 42.774 ms | 492.075 ms | + +The complete medium detector at its production `1x3x160x704` shape still +reliably reports `VK_ERROR_DEVICE_LOST` at the final `C=896, H=5, W=22` +depthwise block. The standalone primitive and the `128x704` full graph pass, +so the fault is an unresolved full-prefix/driver interaction, not a CPU +fallback or missing ONNX operator. `Backend::gpu_only` therefore remains +intentionally unavailable. The measured device route is also slower than the +local AVX-512 CPU, so the project makes no performance-superiority claim over +ONNX Runtime or CPU inference. + +### 2026-08-15: GPU-only qualification recheck + +The strict neural-graph implementation remains pure Vulkan: activations and +model constants stay in `VulkanTensorArena`, and a failed device graph throws +instead of falling back to the CPU executor. The temporary fresh-allocation, +arena-purge, and isolated-depthwise diagnostics used to investigate the Radeon +reset were removed because they did not resolve it; this keeps the production +path reproducible and free of behaviour-changing environment switches. + +The current clean build (`cmake -S . -B build-gpu-only-clean`) and Radeon 780M +recheck passed Vulkan primitive coverage plus strict graph parity for tiny and +small detector `1x3x160x704`, medium detector `1x3x128x704`, and medium +recognizer `1x3x48x320`. The GPU RGB front-end -> detector hand-off passed on +the real `en.ppm` page for tiny and small. The production medium detector +`1x3x160x704` still returns `VK_ERROR_DEVICE_LOST` at its final `896x5x22` +depthwise operation. Consequently, `Backend::gpu_only` and +`full_graph_gpu_available` remain disabled: enabling a supposedly complete +GPU-only API before that failure and end-to-end medium OCR parity are fixed +would violate the correctness contract. No GPU/ONNX Runtime speed claim is +made for this UMA adapter. + +### 2026-08-15: Vulkan full-OCR requalification and MSVC portability + +### 2026-08-16: complete GPU-only reliability work — current status + +The strict Vulkan executor now builds a second, purpose-specific SPIR-V module +for the medium detector's final `896x5x22` depthwise convolution. The module +uses the same five-buffer descriptor layout and 44-byte push constants as the +main graph, but contains only the scalar pad-one depthwise operation. Thus it +does not create a CPU fallback or an activation copy: model constants and all +intermediate tensors remain in the Vulkan arena. + +The shader embedding rule was also fixed for multi-shader builds: each SPIR-V +header now uses an output-specific staging filename, preventing one embed pass +from truncating the other generated C++ header. + +On the local AMD Radeon 780M / LLPC stack, the isolated tail pipeline still +ends the production medium detector `1x3x160x704` execution with +`VK_ERROR_DEVICE_LOST`. It also fails when every node is separately fenced, +when the command buffer object is fresh for every segment, and when free +activation retention is disabled. Tiny detector `1x3x160x704`, small +recognizer `1x3x48x320`, and low-level Vulkan primitive coverage pass after +this change. Consequently the public `Backend::gpu_only` gate remains closed +for correctness: a complete GPU-only API must not claim support on this +adapter until the medium production model passes repeated end-to-end OCR +parity. No CPU neural-network fallback is taken on failure. + +The Vulkan source now defines `NOMINMAX` before including Windows/Vulkan +headers. This prevents the Windows `min`/`max` macros from corrupting C++ +`std::min`/`std::max` calls, and a clean MSVC 19.51/Ninja Release build now +compiles the Vulkan backend and smoke tools. The low-level depthwise route +also no longer records the same descriptor-set bind twice per dispatch. + +On AMD Radeon 780M, refreshed strict-graph checks (three warm passes, upload, +graph, and output download included) were: + +| Model | Shape | Max absolute output error | CPU mean | Vulkan mean | +|---|---:|---:|---:|---:| +| tiny detector | `1x3x160x704` | `4.85918e-07` | 43.604 ms | 61.394 ms | +| small detector | `1x3x160x704` | `1.92900e-07` | 76.702 ms | 123.783 ms | +| medium detector | `1x3x128x704` | `7.23958e-09` | 156.387 ms | 627.358 ms | +| tiny recognizer | `1x3x48x320` | `4.70877e-06` | 12.895 ms | 54.201 ms | +| small recognizer | `1x3x48x320` | `8.94070e-07` | 26.585 ms | 153.499 ms | +| medium recognizer | `1x3x48x320` | `4.17233e-06` | 54.486 ms | 407.467 ms | + +GPU RGB front-end plus strict graph validation passed for tiny and small +detectors on five varied PPM pages (`en`, `zh`, mixed, English-line and +Chinese-line), spanning `64x320`, `128x704`, and `192x704` detector inputs. +The corresponding full public OCR parity test passed all five pages for tiny +and small: 9 decoded results, with worst confidence deviation `2.9e-06` and +`1.7e-06` respectively. The ascending tiny detector device-arena regression +`64x128 -> 96x256 -> 128x512 -> 160x704 -> 64x128` reached 41,385,984 bytes +of reusable capacity and returned after every sample to the 1,713,668-byte +constants-only live baseline. + +The production medium detector at `1x3x160x704` still loses the Radeon +device during the complete FPN tail. Its graph at `1x3x128x704`, standalone +operators, and the tiny/small public OCR paths pass, but the production-size +medium public OCR path does not. Therefore `gpu_only` remains hard-gated; +it never silently falls back to CPU. Hybrid keeps its per-shape full-boundary +rule and only selects Vulkan when measured upload + execution + readback is no +slower than CPU. These results do not support a claim of being faster than +ONNX Runtime on this UMA GPU. + +After a device-loss return, the Vulkan runtime now tears down that invalid +logical device before its next use. A following strict tiny-graph run and the +Vulkan primitive suite both completed successfully in the same process +sequence, confirming that recovery remains GPU-only and does not turn a later +request into a CPU fallback. + +### 2026-08-15: GPU-only allocator/recovery hardening + +The strict Vulkan arena now exposes a monotonically changing resource +generation. `OnnxLite` compares it before each GPU-only run and discards its +model constant-slot cache after a device reset, then re-uploads constants to +the new logical device. This fixes the stale-slot ownership hazard after a +`VK_ERROR_DEVICE_LOST` recovery without allowing any CPU execution path. + +Arena allocations are also rounded only to the required 64-KiB granularity +(rather than adding an unused 1.5x reserve to every independent buffer), and +the graph descriptor pool has 8,192 sets of headroom. On the Radeon 780M this +reduced the medium detector's observed allocated arena capacity before its +FPN-tail reset from about 146 MiB to about 128 MiB. The `1x3x160x704` medium +detector nevertheless still reaches a driver `VK_ERROR_DEVICE_LOST` around +the first FPN `Resize + Add` tail operation. Disabling the FPN fusion and +placing an explicit device-only submit/fence between resize and add did not +remove that fault. The public GPU-only gate remains closed until the complete +medium detector and end-to-end OCR parity pass; there is no silent CPU +fallback and no unsupported performance claim. + +Post-change MSVC Release checks on AMD Radeon 780M passed the Vulkan primitive +suite, tiny detector strict graph (`1x3x160x704`, max error `4.85918e-07`, +GPU `52.2832 ms`) and small recognizer strict graph (`1x3x48x320`, max error +`8.9407e-07`, GPU `96.6479 ms`). Those GPU timings remain slower than the +local AVX-512 CPU for these shapes, so Hybrid retains its full-boundary timing +admission rule. + +### 2026-08-15: GPU-only medium-tail qualification + +The strict Vulkan executor now has an explicitly exercised scalar FP32 +depthwise dispatch for the high-channel `896x5x22` tail shape. It uses an +unallocated shader mode (`52`) and correctly dispatches workgroups (256 +invocations each), avoiding the earlier frontend-mode collision and the +erroneous one-workgroup-per-output-value launch. The Vulkan primitive smoke +validates this exact `C=896, H=5, W=22, 3x3, pad=1` path against a CPU +reference. The full medium detector at `1x3x160x704` nevertheless still +returns `VK_ERROR_DEVICE_LOST` immediately after its final tail dispatch on +the local Radeon 780M/LLPC stack. Therefore this remains a diagnostic, +GPU-only kernel improvement rather than a completed public GPU-only release: +the `gpu_only` gate stays closed and no CPU fallback or performance claim is +introduced. + +### 2026-08-15: device-local Vulkan arena experiment + +The Vulkan tensor arena now supports a device-local storage-buffer route with +host-visible staging buffers. `vkCmdCopyBuffer` transfers only public graph +inputs, constants, and requested outputs; all intermediate PP-OCR feature maps +remain in device-local buffers. Set `PPOCR_GPU_ARENA_DEVICE_LOCAL=0` only to +run the former directly-mapped compatibility path for comparison. + +On the Radeon 780M, primitive arithmetic, image front-end parity, and the +tiny detector graph still pass with this route. The transfer-backed graph did +not resolve the production medium `1x3x160x704` device loss, and on this UMA +adapter its additional boundary copies did not improve timing. The default +CPU/Hybrid admission rule therefore remains unchanged: Hybrid selects Vulkan +only when a measured complete boundary is no slower than CPU. No ONNX Runtime +superiority is claimed from this experiment. + +### 2026-08-15: multi-size GPU graph and residency recheck + +The graph smoke matrix now covers detector inputs from `64x128` through +`192x704`, plus recognizer widths `64` and `320`, across all tiny/small/medium +families. On the Radeon 780M, all listed runs had device/CPU output parity: + +| Model | Shape | CPU ms | Vulkan ms | Max abs. error | +|---|---:|---:|---:|---:| +| tiny detector | `1x3x64x128` | 5.675 | 16.897 | `1.13e-09` | +| tiny detector | `1x3x192x704` | 22.467 | 55.239 | `2.66e-05` | +| small detector | `1x3x64x128` | 10.150 | 38.459 | `7.74e-09` | +| small detector | `1x3x192x704` | 41.085 | 99.252 | `4.60e-07` | +| medium detector | `1x3x64x128` | 24.039 | 75.144 | `4.22e-10` | +| medium detector | `1x3x128x704` | 132.380 | 477.800 | `7.24e-09` | +| tiny recognizer | `1x3x48x64` | 5.274 | 16.755 | `3.52e-06` | +| small recognizer | `1x3x48x320` | 20.938 | 82.170 | `8.94e-07` | +| medium recognizer | `1x3x48x320` | 46.774 | 351.068 | `4.17e-06` | + +The ascending tiny detector memory soak +`64x128 -> 96x256 -> 128x512 -> 160x704 -> 64x128` ended every sample at the +same constants-only live baseline (`1,713,668` bytes), proving activation +release after the largest input. `ppocr_gpu_graph_mem_soak` now reports both +logical device capacity and total allocated residency; at the largest shape +these were `31,719,424` and `63,438,848` bytes respectively because the +device-local route has a matching host staging allocation. These measurements +remain slower than the local AVX-512 CPU and are not ONNX Runtime comparisons; +Hybrid consequently admits only independently measured no-slower segments. + +### 2026-08-16: GPU-only full-path requalification + +The strict Vulkan path remains the intended implementation for complete +GPU-only OCR: image resize/normalization, detector and recognizer graphs, and +terminal CTC Top-1 execute on Vulkan storage. Only compact OCR control data is +returned to the host for DB connected-component traversal and UTF-8 assembly; +there is no CPU neural-network fallback. `gpu_only` remains hard-gated until +the production detector and end-to-end OCR suite pass. + +For the Radeon 780M/LLPC failure investigation, the scalar `896x5x22` +depthwise tail can now be split into GPU-resident channel windows. The normal +path uses four windows; `PPOCR_GPU_TAIL_SLICES=1..896` is a diagnostic +granularity setting, `PPOCR_GPU_TAIL_SUBMIT_SLICES=1` fences those windows +without copying activations to the host, and `PPOCR_GPU_TAIL_GENERIC=1` +selects the original packed route. All three routes still report +`VK_ERROR_DEVICE_LOST` for the production medium detector +`1x3x160x704`; with per-window submission the loss occurs on the first +`C=0..223` scalar window. This localizes the remaining issue to the driver +interaction before/at that dispatch rather than an unsupported ONNX operator. + +Current release checks passed: Vulkan primitive coverage, tiny and small +detector graphs at `1x3x160x704`, medium detector at `1x3x128x704`, and medium +recognizer at `1x3x48x320`. Measured one-run timings on this shared host were +`24.018/50.106 ms`, `37.939/86.509 ms`, `121.056/487.819 ms`, and +`51.734/358.526 ms` (CPU/Vulkan); maximum output errors were respectively +`4.86e-07`, `1.93e-07`, `7.24e-09`, and `4.17e-06`. The repeated ascending +memory soak also passed, returning every sample to the `1,713,668`-byte +constants-only live baseline; at `160x704`, logical capacity was +`31,719,424` bytes and device-plus-staging residency was `63,438,848` bytes. +These results are slower than the local AVX-512 CPU and are not an ONNX Runtime +comparison, so no unsupported GPU performance claim is made. + +### 2026-08-16: pointwise-GELU Vulkan fusion qualification + +The Vulkan shader now has a direct pointwise-convolution plus FP32-GELU +write mode. It removes one full feature-map read/write and one graph dispatch +for `FusedDepthwisePointwiseConvGelu`; the normal mode preserves the existing +separate Vulkan unary GELU path. `PPOCR_GPU_FUSE_POINTWISE_GELU=1` selects the +new all-device fusion for adapter qualification, with identical graph-output +parity (tiny `4.86e-07`, small `1.93e-07`, medium `7.24e-09`). + +On this AMD Radeon 780M/LLPC system, ten-run detector comparisons showed the +fusion is device-dependent: tiny `35.466 -> 33.748 ms` (5.1% faster), small +`88.883 -> 91.514 ms` (3.0% slower), and medium `546.302 -> 643.987 ms` +(17.9% slower), normal/fused. The default therefore retains the faster +separate device kernels while the fused Vulkan implementation stays available +for discrete GPUs or drivers where it wins. This preserves the Hybrid policy: +Vulkan is selected only after a full-boundary no-slower check; no CPU fallback +or unsupported performance claim was introduced. + +### 2026-08-16: complete GPU-only OCR qualification + +`Backend::gpu_only` now executes the complete PP-OCRv6 neural path on Vulkan: +RGB resize/normalization, detector, recognizer, and CTC Top-1 remain on device. +Only DB connected-component control data and final UTF-8 text assembly return to +the CPU; there is no CPU neural-network fallback. The shared Vulkan arena now +has an explicit detector-to-recognizer hand-off that releases idle model +constants and their backing 64 MiB suballocation blocks before the next model +is uploaded. This prevents the two model families from being resident +together on UMA GPUs. + +The matching small/medium dictionary is +`D:\workprj\aicoder\corelib\ocr\dict_ppocrv6.txt` (18,708 lines; 18,710 +CTC classes); tiny uses `dict_ppocrv6_tiny.txt` (6,904 lines; 6,906 classes). +With the matching dictionaries, the public CPU-versus-GPU OCR regression passed +five varied PPM pages (`en`, `line_en`, `line_zh`, `mixed`, `zh`) for every +model tier: 9 decoded results each, with text and geometry identical. Maximum +absolute confidence differences were `0.0494437` (tiny), `0.0136318` (small), +and `0.0081339` (medium). GPU-only uses a right-zero-padded 64-column +recognizer-width grid to avoid driver-sensitive dynamic transformer widths; +this can move its confidence aggregate but does not change decoded text or +geometry on the qualified corpus. + +On the local AMD Radeon 780M / LLPC system, warmed strict-graph comparisons +(two runs; input/output boundary included) were: + +| Model | Shape | CPU mean | Vulkan mean | Max abs. error | +|---|---:|---:|---:|---:| +| tiny detector | `1x3x160x704` | 22.356 ms | 45.910 ms | `4.85918e-07` | +| small detector | `1x3x160x704` | 35.894 ms | 99.619 ms | `1.92900e-07` | +| medium detector | `1x3x160x704` | 160.500 ms | 604.553 ms | `1.81899e-08` | +| tiny recognizer | `1x3x48x320` | 8.852 ms | 36.383 ms | `4.70877e-06` | +| small recognizer | `1x3x48x320` | 20.985 ms | 93.526 ms | `8.94070e-07` | +| medium recognizer | `1x3x48x320` | 51.310 ms | 370.130 ms | `4.17233e-06` | + +The GPU memory soak `64x256 -> 96x512 -> 160x704 -> 64x256` passed. At the +largest tiny-detector input, arena capacity grew to `31,457,280` bytes, while +live storage returned after each image—including the final smaller image—to +the constants-only baseline of `1,713,668` bytes. These Radeon measurements +are slower than the local AVX-512 CPU and are not ONNX Runtime comparisons; +they do not support a claim of GPU superiority. Hybrid retains its +transfer-inclusive no-slower admission policy. + +### 2026-08-16: GPU-only true batch scheduling + +`RecognizeBatch` now has a GPU-only batch path. Pages with identical source +and detector geometry share one Vulkan RGB-resize dispatch and one detector +NCHW graph; detected crops with the same Vulkan-qualified recognition width +share one recognizer/CTC NCHW graph. The implementation retains distinct +source geometries as separate buckets, so it never pads an unlike page or +changes detector resize semantics. If a driver rejects a strict detector batch +(the local medium `N>1` high-channel tail does), it retries those pages as +independent GPU-only graphs after device recovery—never on CPU. + +On four identical `720x152` `en.ppm` pages with `det_batch=4` and +`rec_batch=4`, CPU-versus-batch result parity passed. GPU-only timing on the +Radeon 780M was `434.004 ms -> 292.536 ms` serial/batched for tiny, a `1.484x` +throughput gain. The preceding small-model run measured `1480.410 ms -> +1249.591 ms` (`1.185x`). Medium safely uses the strict N=1 fallback on this +driver; the architecture-specific limitation is explicit rather than a hidden +CPU fallback. The five-image tiny/small/medium GPU-only OCR parity suite and +the ascending memory-recovery soak continue to pass after this scheduling +change. + +### 2026-08-16: GPU-only single-page crop batching + +The same Vulkan NCHW recognizer scheduler is now also used for repeated-width +text crops within a single `Recognize()` call. It groups only crops with the +same qualified 64-column grid, writes each crop directly into its batch plane, +then runs one strict recognizer plus device CTC Top-1 graph. Thus this is a +GPU-only throughput improvement, not a CPU recognizer fallback or a change to +the page geometry contract. + +After rebuilding `build-gpu-only-final`, the five-page public OCR regression +still passed for tiny/small/medium respectively: 9 decoded results with +identical text and boxes, and maximum confidence deltas `0.0494437`, +`0.0136318`, and `0.0081339`. The GPU graph memory recovery sweep also passed +after `64x256 -> 96x512 -> 160x704 -> 64x256`: capacity reached `31,457,280` +bytes at the largest input while live storage returned after every run to its +`1,713,668`-byte constants baseline. + +On the local Radeon 780M, a renewed warmed four-page `en.ppm` batch check +with `det_batch=4`, `rec_batch=4` measured tiny `530.291 -> 311.165 ms` +(`1.704x`) and small `1496.264 -> 1277.662 ms` (`1.171x`), serial/batched. +Both preserve exact GPU-only serial/batch output parity. These are +machine-specific Vulkan figures, not an ONNX Runtime comparison or a claim of +universal GPU superiority. + +### 2026-08-16: GPU-only dense-page upload reuse and memory ladder + +GPU-only recognizer batching now uploads each source page once per +same-width crop batch, rather than uploading the full RGB page once for every +text line. The device resize still writes each crop directly to its own NCHW +plane and the recognizer/CTC graph remains strict Vulkan. This lowers upload +traffic and peak source staging lifetime on dense pages without changing text, +box, or confidence semantics. + +The cross-page scheduler also remembers a driver-rejected exact detector +batch shape. On a later occurrence it immediately schedules independent +strict GPU-only graphs instead of repeatedly provoking the same Vulkan device +recovery. The cache is keyed by source size, detector size, and N; it neither +widens to unqualified shapes nor permits CPU inference. + +`bench/memory_ladder_regression.py` now accepts `--backend gpu`, so the +existing diverse `16x16` through `7680x4320` ladder can check GPU-only host +memory as well. A current tiny GPU-only one-cycle run passed with the required +post-large decline. Its final `64x64` sample was `342,462,464` private bytes +and `363,364,352` working-set bytes, versus the 5K/8K pre-high-water +`490,450,944` and `521,076,736` bytes (about 30.2%/30.3% lower). This observes +process accounting; the separate Vulkan arena regression still proves live +tensor storage returns to the constants-only baseline. + +After the upload-reuse change, the five-page public GPU-only OCR parity suite +again passed for tiny/small/medium (9 results per tier; identical text and +geometry). A renewed warmed four-page batch run on the Radeon 780M measured +tiny `447.936 -> 295.321 ms` (`1.517x`) and small +`1542.215 -> 1280.809 ms` (`1.204x`), serial/batched. These are local Vulkan +measurements, not an ONNX Runtime comparison or a universal speed claim. + +### 2026-08-16: measured Vulkan command-segment tuning + +The strict Vulkan executor now defaults to 20 graph nodes per submitted +command segment (`PPOCR_GPU_ONLY_SEGMENT_NODES` remains an override). The +larger safe segment reduces queue/fence crossings while retaining the explicit +medium-tail device boundary and arena-lifetime hand-off. On the local Radeon +780M mixed three-line page, a 5/10/20/40-node sweep selected 20 as the best +common setting: tiny was `120.753 ms`, small `466.093 ms`, and medium +`2427.856 ms`; 40 nodes regressed all three and 32 regressed medium. The +five-page tiny/small/medium GPU-only OCR parity test still passed after making +the default change. + +For context, a current local mixed-page comparison with that default reported +CPU `41.735 / 99.223 / 336.651 ms`, hybrid `52.127 / 124.219 / 531.973 ms`, +and strict GPU-only `122.299 / 479.389 / 2462.806 ms` for tiny/small/medium. +Hybrid's individual Vulkan admissions remain transfer-inclusive and select GPU +only when that measured primitive boundary is no slower than CPU; these +end-to-end figures show that this UMA adapter does not currently justify a +broader GPU claim. They are not an ONNX Runtime comparison. + +### 2026-08-16: SIMD GPU-upload boundary coverage + +The GPU-only RGB upload boundary now uses a runtime-dispatched byte-to-FP32 +conversion: AVX-512 when the OS/CPU state enables it, AVX2 on compatible x86, +NEON on ARM, and scalar otherwise. This preserves the existing Vulkan shader +ABI and performs no CPU image resize, normalization, or neural operator—the +Vulkan front end still owns all of those operations. The change specifically +removes scalar byte-conversion pressure before GPU submission for large source +pages and detector/recognizer batches. + +The kernel smoke now validates vector blocks plus an odd tail for that upload +conversion. Release validation on the Radeon 780M passed kernel smoke, the +five-page public GPU-only OCR parity suite for tiny/small/medium (same 9 +decoded outputs and prior maximum confidence deltas `0.0494437`, `0.0136318`, +and `0.0081339`), and the strict graph live-storage recovery sweep +`64x256 -> 96x512 -> 160x704 -> 64x256`. The final test retained a +`1,713,668`-byte constants-only live baseline; capacity was `41,615,360` +bytes after the largest shape, which is reusable allocation capacity rather +than live activation storage. + +The one-cycle tiny GPU-only process-memory ladder across the existing +`16x16` through `7680x4320` corpus passed the post-large decline gate. Its +final `64x64` checkpoint was `346,824,704` private bytes and +`365,412,352` working-set bytes, below the observed `5K/8K` high-water of +`520,888,320` and `549,412,864` bytes. This is a memory-lifetime regression, +not a claim that Windows must immediately decommit every reusable allocator +page. + +The broadening corpus also exposed driver/model limits that remain explicit: +tiny/small/medium GPU-only parity passes on `en.ppm` and `mixed.ppm`, while +this Radeon/LLPC stack does not yet execute the medium strict GPU graph for +the extreme `3000x80` strip; it fails closed rather than invoking CPU neural +inference. An unrelated synthetic `ui_dense_1920x1080` page can produce +near-threshold detector-component differences between CPU and FP32 Vulkan +reductions, so it is retained as a stress case, not mislabeled as current +strict geometry parity. Consequently this update makes no claim of universal +GPU superiority or of being ahead of ONNX Runtime; that requires fresh, +matched end-to-end comparisons for every model and corpus case. + +### 2026-08-16: strict GPU-only extreme-short detector qualification + +The dedicated Vulkan depthwise-tail module now also qualifies the medium +detector's named terminal `896x1x30` shape, reached by the `3000x80` strip +after detector resizing to `32x960`. Its padding is decoded from the existing +Vulkan push constants, so both the original `896x5x22` route and the new +short-strip route remain a single purpose-built, device-resident FP32 +dispatch. No ONNX Runtime or CPU neural fallback is introduced. + +On the local Radeon 780M / AMD LLPC stack, the strict detector graph for +`1x3x32x960` completed with maximum CPU/Vulkan output error +`9.60426e-10`. The complete public GPU-only OCR check for medium on +`wide_strip_3000x80.ppm` also passed (one result; confidence delta +`0.0046322`). The standard tiny/small/medium GPU-only OCR corpus was rerun +afterwards and still passed with exact decoded text and geometry; confidence +deltas were `0.0494437`, `0.0136318`, and `0.0081339` respectively. + +The extension deliberately remains narrowly qualified. The same LLPC driver +still loses the device at the medium terminal tail for a larger `17x30` map +(for example a `544x960` detector input, which appears in the 8K memory +ladder). GPU-only continues to fail closed for that unsupported shape. The +medium GPU memory-ladder report is therefore intentionally not claimed as +passing; the already-passing tiny ladder remains the current broad +small-to-large-to-small process-memory evidence. This is correctness and +coverage work, not an ONNX Runtime performance comparison or a universal GPU +speed claim. + +The SPIR-V header generator was also changed to append sixteen bytes per +CMake write rather than one byte per write. This preserves the generated +header layout while reducing generation time for the 170 KiB graph shader and +prevents a timed-out build from leaving a partially emitted header for the C++ +compiler to consume. + +### 2026-08-16: strict GPU-only CTC confidence correction + +The terminal GPU CTC Top-1 reduction now returns the selected value from the +model's already-computed Softmax tensor. An experimental second Softmax over +those probabilities was removed because it changes the public CTC confidence +and is not a valid operator fusion. The recognizer remains entirely +device-resident through resize/normalization, every neural-network operator, +terminal Softmax, and CTC Top-1; only the compact index/probability records +cross back to assemble public text results. + +After a clean shader rebuild, `ppocr_kernel_smoke` passed and strict Vulkan OCR +regression passed for tiny and small on `en.ppm`, `line_en.ppm`, and +`mixed.ppm`, with maximum CPU/GPU confidence deltas `0.0494437` and +`0.0136318`. Medium passed the same three images plus +`wide_strip_3000x80.ppm` with a maximum confidence delta of `0.0081339`. +These runs execute no CPU neural-network operator or ONNX Runtime fallback. +As before, detector DB component traversal and final result-string assembly +are deliberately CPU control-plane work after a GPU result boundary; they are +not model inference. + +### 2026-08-16: terminal Softmax-to-CTC Vulkan fusion and broad memory check + +For the strict GPU-only recognizer, the terminal `Softmax -> CTC Top-1` +sequence is now fused without materialising the full terminal probability +tensor. The GPU CTC dispatch receives the final logits, finds the same +per-row maximum used by stable Softmax, and calculates only the winning +probability as `1 / sum(exp(logit - max))`. This retains greedy CTC indices +and confidence semantics while removing the terminal Softmax read/write and +dispatch. Ordinary public GPU graph output still executes its explicit +Softmax, so the fusion is restricted to the device CTC endpoint. + +The three-tier GPU-only OCR regression was rebuilt after the fusion. Tiny and +small passed `en.ppm`, `line_en.ppm`, and `mixed.ppm`; medium passed those +three plus the `3000x80` short strip. Decoded text and geometry stayed exact, +with maximum CPU/GPU confidence deltas `0.0494437`, `0.0136318`, and +`0.0081339`. `ppocr_kernel_smoke` also passed. + +The reproducible one-cycle tiny GPU-only ladder (`16x16` through `7680x4320` +with wide/tall recovery branches) passed the post-large-memory-decline gate. +The durable final `64x64` checkpoint was `346,030,080` private bytes and +`344,858,624` working-set bytes, below the observed pre-return high water of +`545,927,168` and `554,819,584` bytes. This demonstrates bounded host and +Vulkan arena recovery; it is not an ONNX Runtime performance claim. + +The local Radeon 780M / LLPC timing evidence still does not justify claiming +that GPU-only is universally faster than ONNX Runtime or the host AVX-512 +CPU. In particular, the available ONNX Runtime installation exposes only +`CPUExecutionProvider`, so no matched Vulkan/GPU-provider comparison is +available on this machine. Hybrid continues to use its transfer-inclusive +per-operator admission rule and selects Vulkan only when it measures no +slower than CPU. + +### 2026-08-16: reproducible native-build ORT comparison + +`bench/compare.ps1` and `bench/compare_models.ps1` now accept `-NativeExe`. +This makes a benchmark name the exact CMake build under test rather than +silently selecting `build/ppocr_bench.exe`; for example, the qualified Vulkan +release binary can be passed as +`build-gpu-only-final/ppocr_bench.exe`. The path is emitted in the JSON report +for auditability. + +On the local AVX-512 host, using 16 native/ORT CPU threads, two warmups and +eight timed end-to-end runs of the same `mixed.ppm` page, the selected native +release produced the following CPU-only results against ONNX Runtime 1.28.0 +`CPUExecutionProvider`: + +| PP-OCRv6 model | native mean | ORT mean | native latency improvement | +| --- | ---: | ---: | ---: | +| tiny | 58.679 ms | 164.644 ms | 64.36% | +| small | 100.198 ms | 251.448 ms | 60.15% | +| medium | 433.107 ms | 760.844 ms | 43.08% | + +This is a matched local CPU comparison: detector preprocessing, DB postprocess, +recognizer preprocessing and CTC decode are included by both harnesses. It +proves a substantial benefit for all three model sizes on this corpus; it +does not imply an architecture-independent guarantee. The benchmark's +installed ORT package reports only `CPUExecutionProvider` (plus Azure +metadata), so it is not evidence about an ORT GPU provider. GPU-only and +Hybrid remain available for Vulkan acceleration, while Hybrid retains its +measured no-slower-than-CPU admission policy. + +### 2026-08-16: adaptive Vulkan CTC reduction experiment + +The Vulkan CTC Top-1 shader now contains a cooperative 256-lane vocabulary +reduction for adapters where the terminal recognizer rows are a GPU bottleneck. +It preserves earliest-index tie breaking and computes the selected stable +Softmax probability on device. It is deliberately opt-in via +`PPOCR_GPU_CTC_COOPERATIVE=1`: the Radeon 780M / LLPC default remains the +previous scalar-per-row reduction because the driver-qualified path is faster +and materially more stable there. This keeps the advanced instruction/workgroup +path available for discrete GPUs without regressing the qualified UMA default. + +The default Vulkan path was rebuilt and passed the kernel smoke plus public +GPU-only OCR parity for tiny, small and medium (medium including +`wide_strip_3000x80.ppm`). The cooperative path is therefore an explicit +deployment tuning option, not a benchmark claim until it has been measured on +the destination GPU. + +### 2026-08-16: GPU-only full-network contract revalidation + +The public `Backend::gpu_only` route remains a strict Vulkan neural-network +execution path: RGB resize/normalization, detector, recognizer transformer, +terminal Softmax/CTC Top-1, and recognizer crop batching execute on Vulkan; +construction or execution fails closed if the complete model graph cannot be +lowered. CPU retains only application boundaries: image-byte upload, DB output +geometry/control processing after the detector result is returned, and final +UTF-8 string assembly. No ONNX Runtime library or CPU neural operator is used +by this route. + +The rebuilt release passed `ppocr_kernel_smoke`, the Vulkan RGB/threshold +front-end smoke, and CPU-vs-GPU public OCR parity: tiny and small each passed +`en.ppm`, `line_en.ppm`, and `mixed.ppm`; medium passed those plus +`wide_strip_3000x80.ppm`. Maximum confidence deltas were respectively +`0.0494437`, `0.0136318`, and `0.0081339`, while decoded text and geometry +were exact. + +A fresh local Radeon 780M / LLPC steady-state tiny GPU-only probe on +`mixed.ppm` (one warm-up, three timed runs) measured `137.016 ms` mean, +`131.292 ms` median, and `7.298 FPS`. This is a device-specific Vulkan result, +not a comparison with an ONNX Runtime GPU provider. The accompanying +two-identical-page GPU batch smoke (`det_batch=2`, `rec_batch=2`, one warm-up, +two runs) preserved serial result parity and measured `221.428 ms` serial vs +`194.733 ms` batched mean (`1.137x`). + +### 2026-08-16: GPU-only small-model immutable-residency cache + +GPU-only OCR now keeps a detector/recognizer pair's fused immutable Vulkan +weights resident across the detector-to-recognizer hand-off when their combined +payload is at most `64 MiB` (override with `PPOCR_GPU_CONSTANT_CACHE_MB` before +constructing `OCR`). The hand-off still releases every completed activation; +only model constants remain. Larger pairs, including the local medium model, +retain the prior conservative release-and-reclaim policy for UMA safety. + +This changes no inference operator or fallback policy. A cold comparison with +`PPOCR_GPU_CONSTANT_CACHE_MB=0` confirmed the intended boundary: on Radeon +780M/LLPC, tiny `mixed.ppm` with two warm-ups/eight runs changed from +`318.372 ms` (re-upload per stage) to `133.153 ms` with the resident pair +(`2.39x`). The resident run retained `128.241 ms` median and `7.510 FPS`. +Small and medium remain strict GPU-only graph executions and passed their +public OCR parity suites alongside tiny; all three confidence deltas remain +`0.0494437`, `0.0136318`, and `0.0081339` respectively. + +The policy is deliberately bounded rather than a blanket cache: a tiny +GPU-only `16x16 -> 1920x1080 -> 64x64` process-memory check completed with +completed-activation memory reclaimed before the small return image. The +resident constants establish a stable service baseline; the large page raised +private bytes by `15,728,640` bytes and the final small page did not grow it +further. A full ascending-to-8K ladder remains the stronger regression gate. + +### 2026-08-16: cached GPU-only 8K memory ladder and three-mode snapshot + +The full tiny GPU-only memory regression was rerun after enabling bounded +immutable-pair residency, using the existing `16x16` through `7680x4320` +resolution/aspect-ratio ladder and its recovery tail. It passed +`--require-post-large-decline`. The stable warmed baseline was `250,720,256` +private bytes; the pre-return high-water was `502,628,352` private bytes / +`528,109,568` working-set bytes, while the final `64x64` checkpoint returned +to `256,557,056` / `267,509,760` bytes. The durable report is +`build-gpu-only-final/tiny_gpu_memory_ladder_constants_cached.json`. + +For a separate steady-state `mixed.ppm` snapshot (16 native worker threads, +two warm-ups, eight timed runs), the same release measured: + +| model | CPU-only mean | Hybrid mean | GPU-only mean | preferred local mode | +| --- | ---: | ---: | ---: | --- | +| tiny | 45.476 ms | 53.561 ms | 133.153 ms | CPU-only | +| small | 93.684 ms | 170.108 ms | 462.873 ms | CPU-only | +| medium | 376.173 ms | 542.679 ms | 2435.894 ms | CPU-only | + +These figures are intentionally not presented as a universal GPU win: the +Radeon 780M is an UMA adapter and this full page is CPU-SIMD-favourable. +Hybrid's Vulkan admission remains strict and transfer-inclusive; every +qualified shape chooses Vulkan when measured GPU time is equal to or less than +the CPU segment time, otherwise it preserves the faster CPU segment and avoids +adding latency. GPU-only is available for applications that require its +all-Vulkan neural execution contract, while CPU-only remains the measured +throughput choice for this local corpus. + +### 2026-08-16: GPU-only contract recheck + +The release build was rechecked after the GPU-only integration pass. The +kernel suite, Vulkan RGB resize/normalization smoke, and the real +front-end-to-detector device-slot regression all passed. On `en.ppm`, public +CPU-versus-GPU-only OCR parity passed for tiny, small, and medium, with +maximum CTC-confidence differences of `0.0494437`, `0.0123513`, and +`0.0081339`; decoded text and box geometry were exact. A true two-page tiny +GPU batch (`det_batch=2`, `rec_batch=2`) also completed with serial-equivalent +results, proving that the public batch scheduler submits an NCHW GPU-only +detector and batched recognizer rather than invoking a CPU neural fallback. + +The term *GPU-only* is constrained precisely: packed image bytes are uploaded +from the application, and CPU performs DB connected-component geometry plus +final UTF-8 assembly after the detector/CTC result boundaries. RGB resize and +normalization, all detector and recognizer neural operators, transformer +attention, terminal Softmax/CTC Top-1, and the device crop batches remain on +Vulkan. No ONNX Runtime or CPU neural operator is linked or used by that +path; failure to submit any required Vulkan graph remains fail-closed. + +One deliberately unhidden coverage gap remains: the current Radeon 780M/LLPC +FP32 detector run differs enough from the CPU reference around threshold +boundaries that the dense `ui_dense_1920x1080.ppm` page does not yet preserve +all CPU box/text records. This is not a CPU fallback: it is a numerical-parity +issue to resolve before claiming broad dense-page GPU-only output equivalence. +The qualified normal-page and batch contract above remains passing. + +### 2026-08-16: GPU-only DB postprocess completion + +`Backend::gpu_only` now retains the detector probability map on Vulkan through +the full DB postprocess: thresholding, 8-connected-component traversal, mean +score filtering, rectangular unclip, source-coordinate conversion, and reading +order. The device kernel uses a bounded on-device FIFO (linear in detector-map +pixels); it downloads only final `{x0,y0,x1,y1,score}` records. The previous +full FP32 probability-map download and CPU DB component pass have been removed +from the GPU-only single-page and true-N detector-batch paths. As before, UTF-8 +assembly after the compact device CTC result is host-side application output +formatting, not neural inference. + +Rebuilt `build-gpu-only-final` validation on AMD Radeon 780M/LLPC passed: + +| Check | Coverage | Result | +| --- | --- | --- | +| Kernel + Vulkan front-end | SIMD kernels; RGB resize/normalize; GPU threshold | passed | +| GPU-only OCR, tiny | `en`, `line_en`, `mixed` | 6 results, max confidence delta `0.0494437` | +| GPU-only OCR, small | `en`, `line_en`, `mixed` | 6 results, max confidence delta `0.0136318` | +| GPU-only OCR, medium | `en` | 2 results, max confidence delta `0.0081339` | +| True GPU detector/recognizer batch | 2 identical tiny `en` pages, `det_batch=2`, `rec_batch=2` | serial-equivalent results; `209.975 -> 193.990 ms` (`1.082x`) | + +This is a real GPU-only execution contract—no ONNX Runtime and no CPU neural or +DB floating-point fallback are linked into the route. The published confidence +and dense-page parity caveats still apply; the table is correctness evidence, +not a claim that this UMA GPU is universally faster than CPU or an ORT GPU +provider. + +The GPU-only service path also now reclaims completed transient Vulkan storage +after each public request while retaining the bounded immutable model cache. +`PPOCR_GPU_ONLY_RECLAIM_TRANSIENT=0` is available only for deployment-local +throughput A/B testing. The new one-cycle, ascending `16x16` through +`7680x4320` memory ladder passed `--require-post-large-decline`; its durable +report is `build-gpu-only-final/tiny_gpu_memory_ladder_device_db_reclaimed_20260816.json`. +On that run, final `64x64` private bytes were `409,698,304`, below the warmed +baseline `410,071,040`, and below the pre-return peak `515,739,648`. + +### 2026-08-16: native-byte GPU-only image ingress + +The strict Vulkan front end now uploads the application RGB buffer as packed +native bytes. The resize shader unpacks those bytes on device before its +existing bilinear sampling and BGR normalization; the former CPU +AVX-512/AVX2/NEON byte-to-FP32 widening step is no longer on the GPU-only +request path. The arena remains FP32-sized for common allocator/lifetime +handling, but image ingress consumes only its byte prefix. This is a boundary +change only: detector/recognizer graph operations, DB postprocess, and terminal +CTC reduction remain Vulkan-only, with no ONNX Runtime dependency or CPU +neural fallback. + +Rebuilt validation on the local Radeon 780M/LLPC passed the kernel suite and +front-end smoke, then public strict OCR parity for tiny and small on `en`, +`line_en`, and `mixed` (six records each), and medium on the same three pages +(six records, maximum CPU/GPU confidence difference `0.0081339`). A true +two-page tiny GPU batch (`det_batch=2`, `rec_batch=2`) remained +serial-equivalent and measured `311.699 -> 227.434 ms` mean (`1.371x`) in a +three-run local probe. These are machine-specific Vulkan measurements, not a +claim about an ONNX Runtime GPU provider. + +The full native-byte one-cycle GPU-only memory ladder again passed the required +post-large decline gate. The report is +`build-gpu-only-final/tiny_gpu_memory_ladder_native_rgb_upload_20260816.json`: +the warmed baseline was `409,759,744` bytes, final `64x64` was `409,784,320` +bytes, and the pre-return private-byte peak was `592,015,360` bytes. Thus the +completed large-image workspace fell by 30.8% before the final small-image +checkpoint. + +### 2026-08-22: strict GPU-only requalification and CTC metadata correction + +`Backend::gpu_only` remains a fail-closed Vulkan path: RGB upload/resize and +normalization, detector, Vulkan DB postprocess, crop resize, recognizer, and +CTC Top-1 run on the device. The host receives only final DB records and +compact CTC metadata for UTF-8 result assembly. No ONNX Runtime is linked, and +a Vulkan error is reported instead of selecting CPU neural inference. + +The CTC hand-off now restores the CPU-visible convention that blank and +repeated rows carry zero probability. This changes only compact output +metadata after the Vulkan reduction; it neither downloads logits nor evaluates +an inference operator on CPU. + +Fresh Radeon 780M / LLPC checks from `build-gpu-only-ep`: + +| Check | Result | +| --- | --- | +| Tiny detector `1x3x160x704`, 2 runs | max error `5.63276e-7`; CPU/GPU mean `10.269 / 45.892 ms` | +| Small detector `1x3x160x704`, 2 runs | max error `3.05939e-7`; CPU/GPU mean `19.456 / 65.210 ms` | +| Medium detector `1x3x160x640`, 2 runs | max error `7.56991e-8`; CPU/GPU mean `80.544 / 266.526 ms` | +| Tiny GPU-only OCR corpus | 6 images × 2 runs, 63 records; max confidence delta `0.0011662` | +| Small GPU-only OCR corpus | 6 images × 2 runs, 63 records; max confidence delta `0.0002265` | +| Tiny true GPU batch (`en` × 2, `det_batch=2`, `rec_batch=2`) | serial-equivalent; `92.841 -> 83.830 ms` (`1.107x`) | + +The corpus covers `en`, `mixed`, low-contrast, ultra-wide, ultra-tall, and +`1920x1080` screenshot pages. The dense synthetic UI page remains an explicit +parity stress case: on this driver its GPU DB contour can differ from the CPU +reference by a subpixel amount that becomes a different tiny recognizer crop. +It therefore remains outside the qualified strict-OCR corpus until detector +contour parity is repaired; this is a correctness gate, never a CPU fallback. +These local UMA measurements do not claim to beat ONNX Runtime or CPU SIMD. + +### 2026-08-22: GPU-only execution and memory recheck + +The current public `Backend::gpu_only` route is an all-Vulkan inference +contract: RGB upload/resize/normalization, detector, DB threshold/component +postprocess, recognizer crop resize, recognizer, and CTC Top-1 stay on the +device. The host receives only compact final box/CTC metadata to construct +the public UTF-8 result. A required Vulkan failure is fail-closed; it never +retries the neural graph or DB stage on CPU. + +After rebuilding `build-gpu-only-ep`, the following local Radeon 780M / LLPC +checks passed: + +| Check | Result | +| --- | --- | +| Kernel SIMD/Vulkan smoke | passed | +| Tiny detector `1x3x160x704` | max error `5.63276e-7`; CPU/GPU `10.816 / 44.449 ms` | +| Small detector `1x3x160x704` | max error `3.05939e-7`; CPU/GPU `40.614 / 78.777 ms` | +| Medium detector `1x3x160x640` | max error `7.56991e-8`; CPU/GPU `86.750 / 277.625 ms` | +| Tiny GPU-only OCR corpus | 6 images × 2; 63 records; exact text/geometry; max confidence delta `0.0011662` | +| Small GPU-only OCR corpus | 6 images × 2; 63 records; exact text/geometry; max confidence delta `0.0002265` | +| Tiny true device batch (`en` × 2, detector/recognizer batch 2) | serial-equivalent; `93.460 -> 85.286 ms` (`1.096x`) | + +The same tiny instance was then warmed over an ascending source ladder +(`16x16`, `en`, `mixed`, low contrast, `3000x80`, `80x3000`, screenshot, +dense UI), followed by `en` again. The post-large `en` checkpoint was +`605,151,232 B` private / `505,942,016 B` working set, below the preceding +large-page high-water (`605,732,864 B` / `506,232,832 B`). This verifies that +completed large-image transient storage is released/reused rather than +retained as an ever-growing per-request allocation. + +The synthetic dense UI corpus still has a known CPU/GPU result-parity failure +caused by a subpixel DB-component boundary becoming a different tiny crop. +It remains an explicit regression target, not a supported parity claim and +not a condition that permits CPU fallback. Production medium detector +`1x3x160x704` likewise remains driver-unqualified on this adapter and reports +`VK_ERROR_DEVICE_LOST` fail-closed. These UMA measurements are correctness +and memory-lifetime evidence; they do not claim a universal performance win +over ONNX Runtime or CPU SIMD. + +### 2026-08-22: Vulkan admission and multi-mode recheck + +Hybrid keeps its required transfer-inclusive admission rule: a Vulkan segment +is used only after the same complete boundary is measured no slower than the +CPU SIMD segment. The optional complete-GPU-graph experiment is now read once +when `OCR` is constructed; it cannot accidentally supersede the normal +per-operator no-slower policy during a request. This protects hybrid latency +and CPU utilization on UMA adapters, where a valid complete Vulkan graph can +still be slower than the CPU path. + +On the local Radeon 780M / AVX-512 host, `mixed.ppm` (three text regions, +two warm-ups/five timed runs) measured the following C++ implementation +values: + +| Model | CPU-only | Hybrid | GPU-only | +| --- | ---: | ---: | ---: | +| tiny | `15.616 ms` | `15.888 ms` | `60.750 ms` | +| small | `41.700 ms` | `42.537 ms` | `173.970 ms` | +| medium | `175.402 ms` | `201.552 ms` | unavailable on this production OCR shape | + +Hybrid tracing for medium also observed two eligible Vulkan segments: crop +RGB+Conv.0 (`1.426` vs `1.632 ms`, GPU/CPU) and one terminal CTC GEMM +(`5.438` vs `5.636 ms`). A slower same-model CTC shape (`5.058` vs +`4.350 ms`) remained on CPU. This is the intended behavior: Vulkan lowers +CPU work when it is equal or faster, while slower local segments do not make +the request slower. + +The revised strict Vulkan regression passed tiny and small six-image OCR +corpora (two repeats, 63 records each), the kernel smoke, and a true tiny +N=2 detector/recognizer batch (`98.783 -> 91.599 ms`, `1.078x`). The +small-to-large-to-small GPU memory ladder retained a bounded final `en` +checkpoint of `605,863,936 B` private / `507,125,760 B` working set after +the screenshot and dense-UI phases. These are local results, not an +unsubstantiated claim of universal superiority over ONNX Runtime; a matched +ORT benchmark on the target GPU remains required before making that claim. + +### 2026-08-22: GPU-only replay result consistency + +The strict GPU-only replay path now applies the same compact CTC metadata +convention as the non-replayed GPU path: blank and repeated CTC rows have +zero emitted-character probability. This is performed only after the Vulkan +CTC reduction has downloaded its `[N,T]` result records; logits are never +downloaded and no CPU neural operator is introduced. It prevents a page with +multiple replayed recognition-width graphs from reporting a confidence that +differs merely because its command buffers were coalesced into one queue +submission. + +During the same requalification, the approximate AVX2/AVX-512 vector-exp +sigmoid was changed to an explicit deployment opt-in +(`PPOCR_ENABLE_AVX512_SIGMOID` or `PPOCR_ENABLE_AVX2_SIGMOID`). The default +uses the exact scalar-libm logistic expression because detector probabilities +feed the DB threshold boundary. This restores the tight kernel numerical +check while preserving optional ISA experimentation for deployments that have +qualified its FP32 drift. + +Fresh release checks on the local AMD Radeon 780M / LLPC stack: + +| Check | Result | +| --- | --- | +| Backend probe | Vulkan loader/compute/full graph: `1/1/1`; device `AMD Radeon 780M Graphics` | +| Kernel smoke | passed | +| Detector graph, tiny `1x3x160x704` | max error `5.63276e-7`; CPU/GPU mean `10.798 / 32.052 ms` | +| Detector graph, small `1x3x160x704` | max error `3.05939e-7`; CPU/GPU mean `20.878 / 51.629 ms` | +| Detector graph, medium `1x3x160x640` | max error `7.56991e-8`; CPU/GPU mean `103.525 / 290.357 ms` | +| GPU-only OCR, tiny | 7 images × 2 runs; 64 records; exact text/geometry; max confidence delta `0.0011663` | +| GPU-only OCR, small | 7 images × 2 runs; 64 records; exact text/geometry; max confidence delta `0.0002261` | +| GPU-only replay stress, tiny screenshot (`rec_batch=2`) | 3 runs; 34 records; exact text/geometry; max confidence delta `0.0003594` | + +The qualified image set is `16x16`, English, mixed-script, low-contrast, +ultra-wide, ultra-tall and `1920x1080` screenshot pages. The production +medium OCR detector shape remains fail-closed on this Radeon/LLPC driver with +`VK_ERROR_DEVICE_LOST`; it is a driver qualification limitation, not a CPU +fallback. These results establish complete GPU-only execution and replay +consistency, but they are not a claim that this UMA Vulkan implementation +outperforms ONNX Runtime. + +### 2026-08-22: persistent replay activation-release regression + +The strict Vulkan replay cache now owns the full set of arena slots captured +while its command buffer is recorded, including private intermediate +activations and manually pinned RGB/input slots. Dropping a replay graph (on +model release or optional cache eviction) unpins and releases this complete +set before reusable arena storage is reclaimed. This closes a device-memory +lifetime gap where only public input/output descriptors were previously +released. + +`ppocr_gpu_graph_mem_soak` now accepts `--device-input-replay`. Unlike the +ordinary host-input memory ladder, this mode forces persistent command-buffer +record/replay, releases the model after every shape, and requires both +`live_bytes` and `allocated_bytes` to be zero at each `replay-release` +checkpoint. It is a logical Vulkan-arena test; Windows process +`PrivateUsage` can still retain allocator high-water pages and must not be +misreported as immediately returned physical memory. + +Validated with the release build on AMD Radeon 780M / LLPC: + +| Model | Device-input replay ladder | Result | +| --- | --- | --- | +| tiny detector | `1x3x64x128 -> 96x256 -> 128x512 -> 64x128` | every release: `live=0`, `allocated=0` | +| small detector | `1x3x64x128 -> 96x256 -> 128x512 -> 64x128` | every release: `live=0`, `allocated=0` | + +The normal small-to-large-to-small host-input ladder also remains green: +tiny reaches a `46,006,272`-byte reusable arena high-water and returns after +every sample to its `1,713,924`-byte immutable baseline; small reaches +`73,007,104` bytes and returns to `9,813,844` bytes. Capacity is deliberately +reusable, while the immutable baseline proves no dynamic activation stays +live after the largest shape. + +Reproduce the replay lifetime test: + +```powershell +$models = 'D:\workprj\aicoder\.tmp\ocr-models' +.\build-gpu-only-ep\ppocr_gpu_graph_mem_soak.exe ` + "$models\ppocrv6_tiny_det.onnx" --device-input-replay ` + 1 3 64 128 1 3 96 256 1 3 128 512 1 3 64 128 +``` + +The revised batch fallback keeps the GPU-only contract strict: a rejected +N-batch is remembered for that exact shape and then retried as independent +N=1 Vulkan pages. It does not attempt a speculative runtime reset and never +falls through to CPU neural inference. Current same-page N=2 checks remain +serial-equivalent: tiny `89.904 -> 84.510 ms` (`1.064x`) and small +`247.571 -> 236.356 ms` (`1.047x`). Production medium at its normal OCR +shape is still driver-unqualified on this adapter and fails closed with +`VK_ERROR_DEVICE_LOST`; no successful medium GPU-batch claim is made. + +### 2026-08-22: three-size diverse CPU/ONNX Runtime sample + +`bench/compare_models.ps1` now defaults to a broader real-image set: tiny +input, single word, English, Chinese, mixed-script, low contrast, wide/tall +strips, and `1920x1080`/`2560x1440` screenshots. This makes the standard +benchmark cover scale and aspect-ratio changes instead of only a short +English line. + +For a quick, reproducible CPUExecutionProvider comparison, the release build +was measured with one warm-up and one sample each on `en`, `mixed`, and +`3000x80` wide-strip pages (16 native workers, ONNX Runtime 1.28.0 CPU EP, +same detector/recognizer ONNX files and pipeline semantics). The captured +JSON is `build-gpu-only-ep/cpu_ort_sampled_20260822.json`. + +| Model | Native total | ORT total | Latency improvement | Worst sampled case | +| --- | ---: | ---: | ---: | ---: | +| tiny | `45.357 ms` | `301.243 ms` | `84.94%` | `81.02%` | +| small | `116.614 ms` | `494.681 ms` | `76.43%` | `65.35%` | +| medium | `475.979 ms` | `842.178 ms` | `43.48%` | `16.34%` | + +These are CPU-only results, so they demonstrate the native SIMD/fused path +against the available matched ORT CPU provider rather than incorrectly +attributing the result to Vulkan. The short single-sample run is useful as +a cross-model sanity check, not a replacement for a longer deployment +benchmark. GPU-only tiny/small and hybrid retain their independently tested +Vulkan policy; medium GPU-only continues to fail closed on the tested +Radeon/LLPC production shape. + +### 2026-08-22: hybrid admission and GPU residency tightening + +Hybrid admission now uses one strict rule for its RGB preprocessing, fused +detector-stem, recognizer-stem and graph-level Vulkan boundaries: measured +upload + dispatch + readback must be `GPU <= CPU`. The earlier 15% latency +grace for three RGB/stem paths was removed, so hybrid cannot trade a slower +request merely to move work from CPU. Equal-or-faster GPU segments are still +preferred, exactly as the public backend contract requires. + +On the Radeon 780M / LLPC trace, the small mixed page correctly rejected the +slower GPU detector stem (`8.360 / 6.009 ms`), recognizer stem +(`1.130 / 0.892 ms`) and CTC projections. A medium `1920x1080` trace also +admitted only qualifying CTC shapes (for example `15.470 / 21.808 ms`), while +leaving slower shapes on CPU. Thus hybrid lowers CPU use only where the full +boundary is non-regressive; it is not a blanket Vulkan offload mode. + +`PPOCR_GPU_RECLAIM_TRANSIENT=0|1` is now the common retention switch for both +GPU-only and optional complete-graph hybrid execution; the old +`PPOCR_GPU_ONLY_RECLAIM_TRANSIENT` spelling remains supported. The default +is `1`. A GPU-only tiny multi-size ladder (`16x16`, normal, wide, tall, +1080p, 1440p, then `16x16`) has been captured for the default and explicit +zero-retention policies in `build-gpu-only-ep/tiny_gpu_memory_diverse_20260822.json` +and `build-gpu-only-ep/tiny_gpu_memory_diverse_retain0_20260822.json`. +Windows process accounting still retains allocator high-water pages, so the +authoritative per-graph lifetime gate remains the Vulkan arena's +`live_bytes`/`allocated_bytes` replay regression rather than PrivateUsage +alone. + +### 2026-08-22: runtime-generation-safe hybrid admission + +The RGB/stem hybrid admission caches are now keyed by the Vulkan runtime +generation as well as image and operator shape. A device-loss recovery tears +down arena buffers and can select a different physical-device configuration; +reusing a pre-recovery yes/no verdict would be unsound. The next request now +re-runs its transfer-inclusive qualification automatically, while normal +same-generation requests remain a fast cache lookup. + +An AVX-512 sigmoid A/B was also rechecked. On the 16-worker English sample +it did not show a stable all-model speedup (tiny `14.769 ms`, small +`33.743 ms`, medium `145.255 ms`), so it stays opt-in. Tiny and small +eight-image GPU-only parity runs still passed when the CPU-side option was +present (exact text/geometry; confidence deltas `0.0011663` and `0.0002261`). +Keeping exact default detector sigmoid protects DB threshold boundaries while +leaving a qualified deployment an explicit SIMD option. diff --git a/examples/ppocr_batch_smoke.cpp b/examples/ppocr_batch_smoke.cpp new file mode 100644 index 0000000..252243e --- /dev/null +++ b/examples/ppocr_batch_smoke.cpp @@ -0,0 +1,216 @@ +#include "ppocr/ppocr.hpp" + +#include +#include +#include +#include +#include +#include +#include +#include +#include + +namespace { + +int Positive(const char* text, const char* name) { + try { + const int value = std::stoi(text); + if (value > 0) return value; + } catch (...) { + } + throw std::runtime_error(std::string(name) + " must be positive"); +} + +void OverridePositiveFromEnv(const char* name, int& value) { + if (const char* text = std::getenv(name)) value = Positive(text, name); +} + +double Mean(const std::vector& samples) { + double sum{}; + for (const double value : samples) sum += value; + return sum / static_cast(samples.size()); +} + +double Median(std::vector samples) { + std::sort(samples.begin(), samples.end()); + return samples[(samples.size() - 1) / 2]; +} + +void ApplyBackendFromEnv(ppocr::Backend& backend) { + const char* text = std::getenv("PPOCR_BACKEND"); + if (!text || std::string{text} == "cpu") { + backend = ppocr::Backend::cpu_only; + return; + } + if (std::string{text} == "hybrid") { + backend = ppocr::Backend::hybrid; + return; + } + if (std::string{text} == "gpu") { + backend = ppocr::Backend::gpu_only; + return; + } + throw std::runtime_error("PPOCR_BACKEND must be cpu, hybrid, or gpu"); +} + +bool SameResults(const std::vector& left, + const std::vector& right) { + if (left.size() != right.size()) return false; + for (std::size_t i = 0; i < left.size(); ++i) { + if (left[i].text != right[i].text || left[i].bbox != right[i].bbox || + // Batched detector convolutions legitimately change FP32 reduction + // order versus serial N=1.
