* Addition of streamk fp8 example for CK Tile * Adding in bf8 streamk example in CK Tile * Refactoring fp8/bf8 unit tests Refactored the unit tests for fp8/bf8 to utilize the test harness. Implemented smoke tests with layouts: CCR, CRR, RCR, RRR for fp8/bf8. The tests are using 128x128x32 for the tile configuration, as other configurations revealed implementation gaps that are currently being documented.

Stream-K GEMM
This folder contains examples of Stream-K GEMMs using the 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 gfx942) or leave it blank
../script/cmake-ck-dev.sh ../ <arch>
# Compile the Stream-K kernels
make tile_example_streamk_gemm_basic -j
This will result in an executable build/bin/tile_example_streamk_gemm_basic
