rrz-batch-jobreport

After completion of a batch job the command

rrz-batch-jobreport jobID

displays information on resource usage of the job specified. Currently the command is just a wrapper for the Slurm efficiency script seff. It reports three important quantities:

  • CPU Efficiency (which should be above 90%)
  • Wall-clock time (for possibly adjusting the time limit)
  • Memory Utilization (from which one can decide to request less resources)

Example output:
