Troubleshooting

This topic explains how to troubleshoot common issues seen when running with the MPI Tuner.
Issue
Cause and Possible Solutions
The scheduler of
mpitune
is empty.
  1. Check the arguments for
    mpitune
    and ensure they do not contradicting each other. For example, values for
    --options-set
    and
    --options-exclude
    should not overlap.
  2. If no fabrics or devices pass checking, try running an MPI test application with the same configuration. The issue might be caused by an incorrect host file or cluster configuration.
mpitune
runs very long.
Check the projected schedule before the real launch, using the
–so
option.
Use methods described in task 1 and task 2 and/or their combinations to skip unnecessary jobs
