It is likely that your MPI job will now either abort or experience performance degradation. Local host: %s System call: %s %s Error: %s (errno %d) # [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 setting the MCA parameter "orte_no_session_dir". Local host: %s Filename: %s You can set the MCA paramter shmem_mmap_enable_nfs_warning to 0 to disable this message. # [target full] It appears as if there is not enough space for %s (the shared-memory backing file). It is likely that your MPI job will now either abort or experience performance degradation. Local host: %s Space Requested: %lu B Space Available: %llu B
