One Bit Sparse Matmul

Usage

test kernel

Firstly, pull the denpendence cutlass

git submodule init
git submodule update

Secondly, compile the benchmark test

make 

Thirdly, run the

./a.out --a_rows=1024 --n=1024 --a_cols=1024 --reference-check=false

test python mul

git submodule init
git submodule update

Secondly, compile the benchmark test

make lib

Thirdly, install the python package

pip install -e .

Fourthly, run the base mul

python3 /root/OneBitQuantizer/OneBitSparseMul/tests/python/test_mul.py

Benchmark test

gemm 256x64x128_128x32x128_16x8x32

        using ThreadblockShape = cutlass::gemm::GemmShape<256, 64, 128>;
        using WarpShape = cutlass::gemm::GemmShape<128, 32, 128>;
        using InstructionShape = cutlass::gemm::GemmShape<16, 8, 32>;
