Usage
- Select sites and cluters 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.
- 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
- Running MPI applications is described here
