RMSNorm2D Forward with CK Tile
This example demonstrates 2D Root Mean Square Layer Normalization (RMSNorm) using the CK Tile programming model, a normalization technique widely used in LLMs and transformers.
Algorithm and Math
For each row x:
\text{rms}(x) = \sqrt{\frac{1}{N} \sum_{i=1}^N x_i^2 + \epsilon}
y_i = \frac{x_i}{\text{rms}(x)} \cdot \gamma_i
where \gamma is a learnable scale parameter.
- Tilewise RMSNorm: Each thread block processes a tile (row or block), computes the mean square, normalizes, and applies scale.
Tile Programming Model
- Tiles: Each thread block processes a tile of the input matrix.
- Pipeline: Modular, can be extended for fused operations.
Build & Run
# in the root of ck_tile
mkdir build && cd build
sh ../script/cmake-ck-dev.sh ../ <arch> # you can replace this <arch> to gfx90a, gfx942...
make tile_rmsnorm2d_fwd -j`nproc`
This will result in an executable build/bin/tile_rmsnorm2d_fwd
