Introduction to the cluster usage

The cluster is used mainly in batch mode: In order to start a calculation job scripts are created on or uploaded to one of the login servers. The job script can then be submitted from there to the batch system, which will execute the job on a suitable host. After completion of the job, resulting files are available in the file systems.
