* feat(check_err): add a variable to adjust number of incorrect values to print * feat(host_tensor): add printing capability for fp8 bf8 int8 int4 * fix(gemm_utils): update acceptable data type * fix(host_tensor): print both 4 bit ints in pk_int4_t * refactor(HostTensor): define pk_int4_t_to_int8x2_t and fix typo in vector_type.hpp * feat(host_tensor): add print first n elements functions
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
../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
# The weight preshuffle pipeline on the gemm calculation
make tile_example_gemm_weight_preshuffle -j
This will result in an executable build/bin/tile_example_gemm_basic & build/bin/tile_example_gemm_universal
