This example provides utilities for generating back-to-back (B2B) GEMMs using CUTLASS.

Quick start

A configuration file containing the GEMMs to be fused together is located in config.json. Edit this to change the configuration that you would like to run.

cd ir_gen

# Set up basic variables
out_dir=directory_to_emit_files
cutlass_dir=$(pwd)/../../..
config_file=$(pwd)/../config.json

# Generate code for GEMMs described in `config_file`
./generate.sh $config_file $out_dir $cutlass_dir

# Build the generated code
cd $out_dir
mkdir build && cd build
cmake .. -DGPU_ARCHS="75;80"
make -j

# Run the generated code with M=1024 K0=32 and Batch=1
./sample 1024 32 1

Current restrictions

This experimental example has the following restrictions:

  1. N tile should not exceed 256, or register spilling will occur.
  2. Only FP16 is supported currently
  3. Matrix A must be row major, matrix B must be column major, matrices C and D must be row major.
