Apparently there is, or at least with ompi 1.10. I've now realized IMB pingpong latency on a QDR IB system with ompi 1.10.6+libfabric is ~2.5μs, which it isn't with ompi 1.6 openib. _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
