# GEMM Matrix Multiplication

This folder contains example for Block Scale GEMM using ck_tile tile-programming implementation. 

## build
```
# in the root of ck_tile
mkdir build && cd build
# you can replace <arch> with the appropriate architecture (for example gfx90a or gfx942) or leave it blank
../script/cmake-ck-dev.sh  ../ <arch>
# The aquant pipeline method on the gemm calculation
make tile_example_gemm_aquant_basic -j
make tile_example_gemm_bquant_basic -j
```
This will result in an executable `build/bin/tile_example_gemm_aquant_basic`
