Have you already tested/benchmarked this crate?
Building tblis-src from source requires cmake and Python3. The latter is not nice (not portable). It may make sense to replace TBLIS and BLIS build systems by Rust scripts + cc crate.
I’ve met the author of TBLIS at the tensor contraction workshop in Toulouse earlier this year. I was not aware that Rust bindings exist. I haven’t tried either yet, but we could integrate tblis into mdarray-linalg.
