[QST][CUTE] How to systematically and easily compose the cute layout algebra operations to get custom layout

[danielhua23]

What is your question? Hi,

I am very interested in how to write any custom layout I want using cute like https://github.com/NVIDIA/cutlass/blob/main/tools/util/include/cutlass/util/mixed_dtype_utils.hpp#L362 show, but its very difficult for me to use the layout algebras to compose get any custom layout. That is, I am able to recognize the every operation of layout algebra based on the doc, but I am not able to systematically and easily compose the algebra operations to get any layout I want.

So I wanna consult is there any tutorials about my question? Thanks

reading the source code, understanding the mathematical transforms that are happening, and then building a toolset of your own transformations is the only real way to be able to get to a place where you can write these on your own.

I recommend printing the results of all the intermediate steps in sequences of operations to build a better understanding
