CRC Wrappers

The CRC Team wanted to make your lives a little bit easier. We wrote some scripts to save you time. The scripts are written in Python and Perl. All scripts should accept -h and --help to provide help.

What’s Available?

• crc-sinfo.py: Will show you an overview of the current hardware status.
• crc-squeue.py: Look at your jobs in a convenient way
  • crc-squeue.py --start: Show approximate start time for your jobs, won’t show if you hit association limits
  • crc-squeue.py --watch: Watch your jobs as they progress in time (updates 10 seconds at a time)
  • crc-squeue.py --all: Show all the jobs on the cluster
• crc-scancel.py: Cancel the the job with the JobID 
• crc-quota.py: Show your storage quota on all of our storage systems 
• crc-usage.pl: Show your usage on each cluster
  • For now, this will only show your primary group. Try groups | cut -d' ' -f1 to find your primary group.
• crc-interactive.py: Run interactive jobs on the cluster

  • To submit an interactive job, you should use the CRC wrapper:

    crc-interactive.py --smp --time=1 --num-cores=2

    would give you an interactive job for 1 hour on SMP with 2 processors. When the interactive job starts, you will notice that you are no longer on a login node, but rather one of the compute nodes.

    [shs159@smp-n2 ˜]$
    
    Try crc-interactive.py -h for more details.

  • Note: There is a bug in crc-interactive.py. The Python 2.7 library will be loaded automatically when you run crc-interactive.py. This will prevent you from sourcing a python 3.x environment. See https://crc.pitt.edu/resources/htc-cluster/interactive-jobs for an alternative method. 

• crc-job-stats.py

  • This script is meant to be added at the bottom of your Slurm scripts (after srun) to give the statististic of your job.
