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
