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
• Each site has a separate NFS, therefore, to run an application on several sites at once, you need to copy it: scp, sftp, rsync.
• There is no access to Internet from computing nodes (external IPs should be registered on proxy), therefore, download/update your stuff at the access nodes.
