Queue Summary

The available queues and their associated limits are listed below for all of our HPC systems. The following tables list 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 Clock 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.

Users should submit directly to high, frontier, or standard queues, which are routing queues. Jobs will be moved automatically into the appropriate large job "_lg", small job "_sm", or long walltime "_lw" queues.

Job priority starts at an initial value based on core count and the queue to which the job was submitted. It then increases for each hour that the job has been waiting to run.
