AdaptiveGEMM

Paper Link

This repository is based on the original DeepGEMM. In addition to that, we have added two key features:
  • Adaptation to Various Lengths of Group M: We have enhanced the repository to support different lengths of group M, providing more flexibility for diverse use cases.
  • Support for Group K GEMM: We have also added support for Group K GEMM operations, expanding the functionality of the original DeepGEMM. NOTE: k in each group should be padded to 128x.

Quick start

Requirements

  • Hopper architecture GPUs, sm_90a must be supported
  • Python 3.8 or above
  • CUDA 12.3 or above
    • But we highly recommend 12.8 or above for the best performance
  • PyTorch 2.1 or above
  • CUTLASS 3.6 or above (could be cloned by Git submodule)

Development

# Submodule must be cloned
git clone --recursive git@github.com:InternLM/AdaptiveGemm.git

# Make symbolic links for third-party (CUTLASS and CuTe) include directories
python setup.py develop

# Test JIT compilation
python tests/test_jit.py

# Test all GEMM implements (normal, contiguous-grouped and masked-grouped)
python tests/test_varlen_groupm.py

Installation

python setup.py install
