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](config.json). Edit
|
|
|
|
|
this to change the configuration that you would like to run.
|
|
|
|
|
```shell
|
|
|
|
|
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.
