FlashMLA (CUDA) on Windows

If you want to build and benchmark the FlashMLA CUDA extension on native Windows (MSVC + CUDA) — including SM120 (Blackwell) support — use the wrappers provided in this repo.

• Build SM120 extension: build_flashmla_sm120_windows.bat
• Run benchmark: run_flashmla_sm120_bench_windows.bat
• CMake alternative: external\FlashMLA\windows\build_sm120_cmake.bat

Docs

• external/FlashMLA/windows/README_WINDOWS.md — Windows setup, device selection, and one‑liners.
• external/FlashMLA/docs/SM120_TMEM_TMA_PORT.md — SM120 split‑build design and kernel/layout notes.

Notes

• SM120 binaries run only on SM120 GPUs (e.g., Blackwell in WDDM). For Ada (4090), build SM100 instead: external\FlashMLA\windows\build_sm100.bat.
