Here are the queues available on Pitzer.
Note that in SLURM, queues are known as partitions as well.
|NAME||MAX WALLTIME||NODES AVAILABLE||MIN JOB SIZE||MAX JOB SIZE||NOTES|
|Serial||168 hours||Available minus reservations||1 core||1 node|
|Longserial||336 hours||Available minus reservations||1 core||1 node||Restricted access (contact OSC Help if you need access)|
|Parallel||96 hours||Available minus reservations||2 nodes||40 nodes|
|Longparallel||TBD||Available minus reservations||2 nodes||TBD||Not currently supported.|
|Hugemem||168 hours||4 nodes||1 core||1 node|
|Largemem||168 hours||12 nodes||1 core||1 node|
|Parallel hugemem||TBD||4 nodes||2 nodes||TBD||Not currently supported.|
|Parallel largemem||TBD||12 nodes||2 nodes||TBD||Not currently supported.|
|GPU serial||168 hours||Available minus reservations||1 core||1 node||Includes dual GPU and quad GPU nodes|
|GPU parallel||96 hours||Available minus reservations||2 nodes||10 nodes||Includes dual GPU and quad GPU nodes|
|Debug-regular||1 hour||Available minus reservations||1 core||2 nodes||For small interactive and test jobs|
|Debug-GPU||1 hour||Available minus reservations||1 core||2 nodes||For small interactive and test GPU jobs|
- "Available minus reservations" means all standard dense or GPU compute nodes in the cluster currently operational (this will fluctuate slightly), less the reservations for specific projects.
- To access one of the restricted queues, please contact OSC Help. Generally, access will only be granted to these queues if the performance of the job cannot be improved, and job size cannot be reduced by splitting or checkpointing the job.
- Only up to 2 quad GPU nodes can be requested in a single job
