Running Jobs on Olga

The Olga cluster is an owner-based access SCS resource. The Olga cluster is configured to serve long running batch style jobs, by using either the Sun Grid Engine or Condor. Jobs run outside of these two systems will be terminated after 30 minutes. SGE provides the principle submission method and Condor acts as an opportunistic backfilling mechanism. Jobs submitted to the SGE have priority over Condor jobs, hence only one SGE job can be submitted at a time. See the Resource Policy section below for more details. Jobs submitted to the Condor queue, while secondary to the SGE queue, can run on more than just the Phoenix cluster. Jobs submitted to the Condor queue may be matched with a machine in another cluster or a desktop or classroom workstation.
