Looks OK to me.
Is logging from just rank==0 sufficient?
It's going to be noisy anyway, so would logging from all ranks provide any extra debug opportunities?

sorry missed your comment. I think rank 0 should be sufficient. because one NCCL level RS/AG will be converted to many low-level SHARP level calls and it will be a huge log otherwise.
