Usage

  • Select sites and clusters for experiments, using information on the Grid5000 network
  • 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.
  • 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:

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

Batch job on installed images:

$ oarsub BATCH_FILE -t allow_classic_ssh -l [/cluster=N/]nodes=N,walltime=HH[:MM[:SS]] [-p 'PROPERTY="VALUE"']
  • The image to deploy can be created with help of a Systemimager-like system Kadeploy. A Linux distribution lenny-x64-nfs-2.1 with mc, subversion, autotools, doxygen, MPICH2, GSL, Boost, R, gnuplot, graphviz, X11, evince is available at Orsay /home/nancy/alastovetsky/grid5000.
  • Running MPI applications is described here
