* Support bf16/fb8/bf8 datatypes for ck_tile/gemm * remove commented out code. * Addressing code review comments and enabling universal_gemm for all the supported data types. * Merge conflict resolution. * Solve the memory pipeline compilation error. Merge with the new change of CShuffle * finish the feature, pass the tests * Fix the pipeline and add the benchmark script for other data types --------- Co-authored-by: ThomasNing <thomas.ning@amd.com>
GEMM Matrix Multiplication
This folder contains example for GEMM using ck_tile tile-programming implementation. Currently, it only supports the basic feature of the CK Tile GEMM, but creates the placeholders for the future support on different GEMM pipeline and different GEMM modules. In the near future, we will gradually migrate all the GEMM features from old CK to CK Tile.
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>
# The basic pipeline method on the gemm calculation
make tile_example_gemm_basic -j
# The memory bound pipeline on the gemm calculation
make tile_example_gemm_universal -j
This will result in an executable build/bin/tile_example_gemm_basic & build/bin/tile_example_gemm_universal
