CUda Matrix Multiply library.
cumm is developed during learning of CUTLASS, which use too much c++ template and make code unmaintainable. So I develop pccm, use python as meta programming language, to replace c++ template meta programming.
Now pccm become a foundational framework of cumm and my other c++ project such as spconv.
cumm also contains a python asyncio-based gemm simulator that share same meta program with CUDA code, enable gemm visualization and easy debug experience.
We offer python 3.9-3.13 and cuda 11.4/11.8/12.1/12.4/12.6 prebuilt binaries for linux (manylinux_2_28).
We offer python 3.9-3.13 and cuda 11.4/11.8/12.1/12.4/12.6 prebuilt binaries for windows 10/11.
We offer python 3.9-3.13 prebuilt binaries for Mac OS X >= 14.0 (Apple Silicon Only).
pip install cumm for CPU-only
pip install cumm-cu114 for CUDA 11.4
pip install cumm-cu126 for CUDA 12.6
WARNING Use code in tags!!! code in main branch may contain bugs.
The c++ code will be built automatically when you change c++ code in project.

WARNING: If CUMM_CUDA_VERSION is set with a CUDA version, following steps will create a wheel named "cumm-cuxxx", not "cumm", this means you must use cumm-cuxxx in dependency of your project which depend on cumm, not cumm. If CUMM_CUDA_VERSION isn't set, cumm will always built with CUDA, so the CUDA must exists in your system. The wheel name will be cumm even if it is built with cuda.
It's recommend to build Linux packages in official build docker. Build with CUDA support don't need a real GPU.
