"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.

 

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