FLATMM Matrix Multiplication with CK Tile
This example demonstrates FLATMM (flattened matrix multiplication) using the CK Tile programming model. FLATMM is a variant of GEMM optimized for certain memory layouts and batch processing patterns. Currently, it only supports the basic feature of the CK Tile FLATMM, but creates the placeholders for the future support on different FLATMM pipeline and different FLATMM modules. In the near future, we will gradually migrate all the FLATMM features from old CK to CK Tile.
Algorithm and Math
Given:
A:[\text{batch}, M, K]B:[\text{batch}, K, N]C:[\text{batch}, M, N]
For each batch b:
C^{(b)} = A^{(b)} \times B^{(b)}
- FLATMM: An alternative solution as the Preshuffled GEMM in /03_gemm
Build & Run
# 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 flatmm calculation
make tile_example_flatmm_basic -j
This will result in an executable build/bin/tile_example_flatmm_basic
