Tips and Tricks

  • Access is provided via access nodes: access.SITE.grid5000.fr. As soon as you are on one of the sites, you can directly ssh frontend node of any other site: frontend.SITE2.
  • Jobs are run from the frondend nodes, using a PBS-like system OAR. Basic commands:
    • oarstat - queue status
    • oarsub - job submission
      • interactive job
$ oarsub -I


      • batch job
        $ oarsub path_to_batch_file
        
    • oardel - job removal
