# Rmsnorm2D forward

This folder contains example for Rmsnorm2D forward using ck_tile tile-programming implementation.

## build
```
# 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`

## cmdline
```
