I raised the issue of MXM hurting p2p latency here a while ago, but don't have a solution. Mellanox were here last week and promised to address that, but I haven't heard back. I get the impression this stuff isn't widely used, and since it's proprietary, unlike PSM, we can't really investigate. _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
