Queues - Defines how and where jobs are run. This may include many host groups and be restricted to certain users. Use -q <queue_name> to submit to a particular queue. If no option is given, then defaultfaculty.q is used.

Priority Queue - This queue has priority on the machines. Jobs from other queues will be suspended in favor of this jobs from this queue.

Host - A single machine/server/node Use -q <queue_name>@<host_name> to submit to particular machine.

Host Group - A listing of different hosts. Use -q <queue_name>@@<host_group> to submit to particular host group.

Examples

  • qsub -q defaultfaculty.q@@students submission_script.sh
    • Submits to the defaultfaculty.q queue, but restricts the job to only the machines in the students host group.
  • qsub -q gpu.q@gpu9 submission_script.sh
    • Submits to the gpu.q queue but restricts the job to only 1 server (gpu9)
