"Available minus reservations" means all nodes in the cluster currently operational (this will fluctuate slightly), less the reservations listed below. To access one of the restricted queues, please contact OSC Help. Generally, access will only be granted to these queues if performance of the job cannot be improved, and job size cannot be reduced by splitting or checkpointing the job.

In addition, there are a few standing reservations.

Name Times Nodes Available Max Walltime Max job size notes
Debug 8AM-6PM Weekdays 12 1 hour 12 nodes For small interactive and test jobs.

Small jobs not requiring GPUs from the serial and parallel queues will backfill on this reservation.

OneTB ALL 1 48 hours 1 node Holds the 32 core, 1 TB RAM node aside for the hugemem queue.

 

Occasionally, reservations will be created for specific projects that will not be reflected in these tables.
