CUTLASS GEMM

Multiple GEMM operators are constructed with cutlass to support LLM inference.

GEMM

The calculation expression is as follows, where the precision of Matrix A, B, C and D is FP16 or BF16. You can also customize your own epilogue. In some scenarios, it exceeds the performance of cublas and cublasLt.

D = alpha * (A * B) + beta * C

Compile

Environment

  • OS: Linux
  • Cmake Version: >= 3.16
  • GCC Version: >= 5.0
  • CUDA Version: >= 11.4
  • Others: gflags, ccache
sudo apt-get install libgflags-dev ccache

Clone

git clone https://github.com/Bruce-Lee-LY/cutlass_gemm.git

Build

NVIDIA A100

cd cutlass_gemm
./build.sh -a 80 -t Release -b OFF
./build.sh -a 80 -t Debug -b OFF

RTX3080Ti / RTX3090 / RTX A6000

cd cutlass_gemm
./build.sh -a 86 -t Release -b OFF
./build.sh -a 86 -t Debug -b OFF

Run Sample

./run_sample.sh

Performance

Process the data in the log and plot it as a line chart.

cd tools/performance
./performance.sh

GEMM

  • GPU: RTX3090
  • CUDA Version: 12.1
  • Data Type: FP16
  • Beta: 0.0

Performance achieved by current cutlass methods.

K == N == 4096

Reference

Add '#include <cute/numeric/math.hpp>' to file 'cute/algorithm/functional.hpp' to avoid error 'namespace "cute" has no member "max"' during compilation.

TODO

  • Add SM90 Kernel
