[QST] Are there plans to add specialisations for Sm90?

[joerowell]

What is your question?
I recently tried to change the type tags on the DGEMM examples to cutlass::arch::Sm90, which caused a load of compile errors. This is primarily because there's certain template specialisations missing for Sm90, e.g there's no specialisation like this.

Is this something that's on the plans to be added / are PRs welcome?

the link points to dual gemm example not dgemm. do you want dual gemm or dgemm?

[joerowell]

Ah sorry, laxness on my part. I meant dual GEMM.

@danthe3rd

you should be able to still run this example on h100 without changing the source code. just use sm90 in nvcc/cmake command line.

this example does not use new features of hopper. we are looking to write a hopper dedicated version using cutlass 3.x

Note: we with @joerowell and others are working on a diverged hard fork of xformers that has little to do with the mainstream 😉 We are rewriting the orignal kernels, doing a lot of optimizations, fixing bugs, etc.

@joerowell optimizations for dual GEMM are on our roadmap for H1'24.

@mnicely Hi! Is any update in roadmap for dual GEMM optimizations? Will this optimization appear? Or you reprioritized this task? Or it is too difficult to optimize for hopper ?
