The available resources dedicated to each queue are subject to change, so please double check on the cluster of interest using the llclass -l command.

Queue Descriptions

On each cluster, there are 8 processors available on the head node for interactive queue and 104 processors available on the compute nodes. The 8 processors on the head node are available via the interactive queue only.

Please note that processors are not exlcusive to a particular queue. One example of this is that the set of all processors in the preempt queue is a subset of the checkpt queue. Submitting to the checkpt queue is done so with the knowledge that a job may be preempted for a high priority situation.

interactive

This queue is usefule for debugging parallel application or using multithreaded, interactive applications. It requires no explict queue script, and it can be accessed via the command line on the head node using the command:

preempt

This queue is a subset of cpus in the checkpt queue that may be preempted by a controlled set of users. Submitting to the checkpt queue is done so with the knowledge that a job may be preempted for a high priority situation.
