Submit Notes

The config file option 'submit' was used.

General Notes

 MPI startup command:
   mpirun command was used to start MPI jobs. This command starts
   an independent ring of mpd daemons, launches an MPI job, and shuts
   down the mpd ring upon the job termination.
   The mpirun command automatically detects if an MPI job is submitted
   in a session allocated using a job scheduler (like PBS Pro). In this
   case, the mpirun command extracts the host list from the respective
   environment and uses these nodes automatically.

 PBS Pro was used for job submission. It has no impact on performance.
