It is likely that your MPI job will now either abort or experience performance degredation. Local host: %s System call: %s %s Error: %s (errno %d) # [mmap too small] Open MPI requested a shared memory segment that was too small to do anything useful. This is likely an error in Open MPI itself. If you see this error, you should see if there is an update available for Open MPI, and if not, contact the Open MPI developers. Local host: %s Requested size: %ul Control seg size: %ul Data seg aligment: %ul # [mmap on nfs] WARNING: Open MPI will create a shared memory backing file in a directory that appears to be mounted on a network filesystem. Creating the shared memory backup file on a network file system, such as NFS or Lustre is not recommended -- it may cause excessive network traffic to your file servers and/or cause shared memory traffic in Open MPI to be much slower than expected. You may want to check what the typical temporary directory is on your node. Possible sources of the location of this temporary directory include the $TEMPDIR, $TEMP, and $TMP environment variables. Note, too, that system administrators can set a list of filesystems where Open MPI is disallowed from creating temporary files by settings the MCA parameter "orte_no_session_dir".
