Queue Summary

The available queues and their associated limits are the same on all of our HPC systems. The following table lists the queues in order of priority from highest to lowest. The Queue Name is the name of the queue as it appears on the systems. The Job Class is the class of jobs that may be run in that queue. Queues without a Job Class can run any class of jobs. Max Wall Time is the maximum lifetime for any job running in a queue, and Max Cores per Job is the maximum number of cores that may be allocated to any single job in a given queue.
