From ac146e6fbec265c37a1e7b251b56077be3e78e65 Mon Sep 17 00:00:00 2001 From: Devan Carlin Date: Sat, 22 Aug 2026 07:54:22 -0700 Subject: [PATCH 1/8] feat(platform): native Windows (MSVC + CUDA) build for ninfer-serve Port the engine to build and run natively on Windows (no WSL2), serving the same .ninfer artifacts with byte-identical output and equal-or-better throughput. Platform code: - artifact/reader.cpp: MappedFile Windows branch (CreateFileW/MapViewOfFile/SetFilePointerEx+ReadFile); fix LARGE_INTEGER aggregate-init truncating file offsets >= 4 GiB (must set .QuadPart) - request_log.cpp: getpid -> GetCurrentProcessId; load_progress.cpp: isatty -> GetConsoleMode; acquire.cpp: Winsock branch - CMake: NINFER_BUILD_MEDIA option (OFF on Windows) + decode/acquire stubs; MSVC C++20 friction fixes NVFP4 TMA fix (Windows-only crash at T>=1024 prefill): MSVC cannot pass the 128-aligned CUtensorMap by value (C2719), so the kernels take a pointer. The TMA unit reads tensor maps through a separate tensormap proxy: kernel-side (generic-proxy) writes to a descriptor staged in local memory are invisible to it without fence.proxy.tensormap, which surfaced as 'Illegal instruction' at the first cp.async.bulk.tensor. Both TMA kernels now read the descriptor directly from the host-written global buffer (cudaMalloc'd, 256-byte-aligned, cudaMemcpyAsync H2D) - no in-kernel staging, no fence. Verified: 1024-token repro + 24k needle (ZEBRA-42-QUARTZ-7719) pass; WSL<->Windows byte-identical parity (seed 42, content + reasoning); compute-sanitizer clean (zero memory errors); prefill 6378 tok/s, decode 172.5 tok/s (WSL baseline 115-125). --- CMakeLists.txt | 34 ++++- src/CMakeLists.txt | 28 +++- src/artifact/materializer.cpp | 33 +++++ src/artifact/reader.cpp | 120 +++++++++++++++++- src/core/verbose.h | 37 ++++++ src/media/decode/decode_stub.cpp | 30 +++++ src/ops/linear/nvfp4/nvfp4_w4a4_tma.cu | 5 +- src/ops/linear/nvfp4/nvfp4_w4a4_tma.cuh | 47 ++++++- .../nvfp4/nvfp4_linear_swiglu_w4a4_tma.cu | 4 +- .../nvfp4/nvfp4_linear_swiglu_w4a4_tma.cuh | 26 ++-- src/ops/wrapper/embedding.cpp | 67 ++++++++++ src/product/load_progress/load_progress.cpp | 13 +- src/product/media_acquire/acquire.cpp | 14 ++ src/product/media_acquire/acquire_stub.cpp | 25 ++++ src/serve/console_log.cpp | 4 + src/serve/request_log.cpp | 12 +- src/targets/qwen3_6/impl/runtime/api_impl.h | 42 ++++-- .../qwen3_6/impl/runtime/text_context_impl.h | 67 ++++++++++ tests/CMakeLists.txt | 8 +- 19 files changed, 569 insertions(+), 47 deletions(-) create mode 100644 src/core/verbose.h create mode 100644 src/media/decode/decode_stub.cpp create mode 100644 src/product/media_acquire/acquire_stub.cpp diff --git a/CMakeLists.txt b/CMakeLists.txt index ca3f6c48e3..d16b0cd514 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -39,6 +39,28 @@ if(CMAKE_CUDA_COMPILER_VERSION VERSION_LESS 13.1) "${CMAKE_CUDA_COMPILER_VERSION}") endif() +# CUDA 13's CCCL headers require MSVC's standard-conforming preprocessor. +if(MSVC) + add_compile_options($<$:-Xcompiler=/Zc:preprocessor>) + # windows.h defines max/min as macros that break std::max/std::min. + add_compile_definitions(NOMINMAX) +endif() + +# Media (vision) decode and acquisition need FFMPEG and libcurl.
