What
This PR contains various optimizations for TL/MLX5/a2a. In order of importance/relevance:
We might want to merge this PR as is, or to divide it into several smaller ones. But this branch is at least a pointer for a working version, that can be used as is for performance experimentation.
TODO:
One important optimization that is yet to be implemented is to support using several NICs. So far, our algorithm only uses one NIC.
