Batched GEMM
This folder contains example for batched 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
sh ../script/cmake-ck-dev.sh ../ <arch>
make tile_example_batched_gemm -j
This will result in an executable build/bin/tile_example_batched_gemm
