Jobs

Overview

The Jobs menu on the menu bar includes both the Job Composer and the Active Jobs tools. The Job Composer assists you to set up and submit jobs to the cluster through a graphical interface using file management tools and access to job templates.

  • Click Save to apply changes.
  • Select an existing job from your list.
  • Click New Job > From Selected Job.
  • This duplicates the job, allowing you to modify it without altering the original.
  • Click New Job > From Specified Path.
  • Enter the full path to a directory containing your job script and necessary files.
  • This is useful for jobs prepared outside the Job Composer.

Editing the Job Script

  1. In the Job Composer, locate your job and click Open Editor under the Submit Script section.
  2. Modify the main_job.sh script with your desired commands and SLURM directives. For example: 
    #SBATCH --output=%x.%j.out # %x.%j expands to slurm JobName.JobID
#SBATCH --error=%x.%j.err
#SBATCH --partition=general
#SBATCH --qos=standard
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=1
#SBATCH --time=01:00  # D-HH:MM:SS
#SBATCH --mem-per-cpu=4000M
  3. Ensure you adjust the SLURM directives (#SBATCH lines) according to your job’s requirements.
  4. Click Save after editing.

Submitting the Job

  1. In the Job Composer, select your job.
  2. Click Submit.
  3. Monitor the job’s status under the Active Jobs tab.
    • Queued: Waiting for resources.
    • Running: Currently executing.
    • Completed: Finished execution.

Active Jobs

The Active Jobs tool will allow you to view all the jobs you’ve submitted that are currently in the queue, via OnDemand or not, so you can check on their status.
