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. Max Wall Clock Time is the maximum lifetime for any job running in a queue. Max Jobs is the maximum number of jobs per user that may run simultaneously. Min Cores Per Job is the minimum number of cores that a job must request in order to run in the queue. 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.
