Hi, --mca mpi_leave_pinned 1
might help. Take a look at the FAQ for various tuning parameters. Michael Di Domenico wrote:
I'm not sure I understand what's actually happened here. I'm running IMB on an HP superdome, just comparing the PingPong benchmark HP-MPI v2.3 Max ~ 700-800MB/sec OpenMPI v1.3 -mca btl self,sm - Max ~ 125-150MB/sec -mca btl self,tcp - Max ~ 500-550MB/sec Is this behavior expected? Are there any tunables to get the OpenMPI sockets up near HP-MPI? _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
