Usage

  • Select sites and clusters for experiments, using information on the Grid5000 network and the Status page
  • Access is provided via access nodes access.SITE.grid5000.fr marked here as accessible from everywhere via ssh with keyboard-interactive authentication method. As soon as you are on one of the sites, you can directly ssh frontend node of any other site:
access_$ ssh frontend.SITE2
  • 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. Several revision control clients are available.
  • Each site has a separate NFS, therefore, to run an application on several sites at once, you need to copy it scp, sftp, rsync between access or frontend nodes.
  • Jobs are run from the frondend nodes, using a PBS-like system OAR. Basic commands:
    • oarstat - queue status
    • oarsub - job submission
    • oardel - job removal

Interactive job on deployed images:

fontend_$ oarsub -I -t deploy -l [/cluster=N/]nodes=N,walltime=HH[:MM[:SS]] [-p 'PROPERTY="VALUE"']

Batch job on installed images:

fontend_$ oarsub BATCH_FILE -t allow_classic_ssh -l [/cluster=N/]nodes=N,walltime=HH[:MM[:SS]] [-p 'PROPERTY="VALUE"']

Loading:

fontend_$ kadeploy3 -a PATH_TO_PRIVATE_IMAGE_DESC -f $OAR_FILE_NODES

  • Running MPI applications is described here
  • Compilation should be done on one of the reserved nodes (e.g. ssh `head -n 1 $OAR_NODEFILE`)
  • MPI applications should be launched from one of the reserved nodes (e.g. ssh `head -n 1 $OAR_NODEFILE`)
