# permute
This folder contains example for permute kernel, which is similiar to [torch.permute](https://pytorch.org/docs/stable/generated/torch.permute.html) (combined with [torch.contiguous](https://pytorch.org/docs/stable/generated/torch.Tensor.contiguous.html)). Currently we implement a generic permute kernel that support up to rank 8 arbitrary permutation with a single kernel instance. Performance is not the first consideration, we prefer a simple and general kernel implementation using `ck_tile` in this example.
```
args:
-v weather do CPU validation or not (default:1)
-prec data type. fp16/bf16/fp32 (default:fp16)
-shape the shape of the input tensor (default:2,3,4)
-perm permute perm (default:2,1,0)
```
## 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_example_permute -j
```
This will result in an executable `build/bin/tile_example_permute`
## some examples
```
# torch
x=torch.randn(2,3,4,6)
y=x.permute(0,3,2,1).contiguous()
# ck_tile
./build/bin/tile_example_permute -shape=2,3,4,6 -perm=0,3,2,1
```
or you can try the smoke_test
```
# in the root of ck_tile, after you build this example
sh example/ck_tile/06_permute/script/smoke_test.sh
```
### alternative implementation
we have an alternative implementation under `alternative_impl/` folder, that can swizzle the tensor to be more friendly for data loading for matrix core layout. This can be enabled when dealing with a `rank-7` tensor, with a fixed pattern of either `0,1,4,2,5,3,6` or `0,1,2,4,5,3,6`. There are other shape limitation of this implementation, check the source code of `permute.cpp` for detail.
```
# example
./build/bin/tile_example_permute -shape=3,6,4,32,16,2,8 -perm=0,1,4,2,5,3,6 # b_n0_k0_n1_k1_n2_k2
./build/bin/tile_example_permute -shape=3,8,4,16,16,4,8 -perm=0,1,2,4,5,3,6 # b_n0_n1_k0_k1_n2_k2

# topk-softmax
This folder contains example for topk-softmax kernel using ck_tile tile-programming implementation. This kernel is often used in Moe model, before launching the fused-moe-gemm block. The input is a `token*expert` 2d matrix. The op will do a softmax per row(`expert`), then find the `topk` value for each row. Output is a `token*topk` weight(usually fp32) and index(int32) 2d tensor.
## 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_example_topk_softmax -j
```
This will result in an executable `build/bin/tile_example_topk_softmax`
## example
```
args:
-v weather do CPU validation or not (default:1)
-pr_i input data type. fp16/fp32 (representing 8/16/32 bit data) (default:fp16)
-pr_w output weight data type(currently only fp32 supported now) (default:fp32)
-t number of input tokens (default:32)
-e number of experts (default:8)
-k topk (default:2)
-st_i row stride of input, -1 means same as experts (default:-1)
-st_o row stride of output/indices, -1 means same as topk (default:-1)
-seed seed to be used, -1 means random every time (default:-1)
-kname when set to 1 it will print kernel name (default:0)
