MOAB Queues

There are a number of job queues available on the cluster and depending on your user type (owner-base or general access) you can submit your job to one of those. For an actual list of queues, see this list.

Time limitations

Jobs submitted to the backfill queue have a wallclock time restriction: their runtime can not exceed 4 hours. When that time limit is exceeded, your job will be cancelled. If you try to reserve a longer walltime than 4 hours, the scheduler will refuse your job.

Examples

Run a job in the backfill queue:

 $ msub -q backfill trap-mpichv2.sh 

Run a job with high-priority:

 $ msub -l qos=scs_high trap-mpichv2.sh 

Change the quality of service from a job that is waiting

$ checkjob 23831
...
Creds:  user:paulvdm  group:paulvdm  class:scs_q  qos:scs_high
...
$ setqos med 23831
$ checkjob 23831
...
Creds:  user:paulvdm  group:paulvdm  class:scs_q  qos:med
...
