I lost track of this, but the problem went away using libfabric instead of openib, so I left it at that, though libfabric hurt IMB pingpong latency compared with openib. I seem to remember there's a workaround in the cp2k development source, but that obviously doesn't solve the general problem. _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
