We have been experiencing an issue with the Ethernet switches in the Owens cluster. 

Queues and Reservations

Here are the queues available on Pitzer. Please note that you will be routed to the appropriate queue based on your walltime and job size request.

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
Parallel 96 hours Available minus reservations 2 nodes 40 nodes   
Longparallel TBD Available minus reservations 2 nodes TBD Restricted access
Hugemem 48 hours 4 nodes 1 node 1 node  
Parallel hugemem TBD 4 nodes 2 nodes 4 nodes Do not support for now
Debug-regular 1 hour 6 nodes 1 core 2 nodes -q debug
Debug-GPU 1 hour 2 nodes 1 core 2 nodes -q debug

"Available minus reservations" means all nodes in the cluster currently operational (this will fluctuate slightly), less the reservations listed below. 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.

Occasionally, reservations will be created for specific projects that will not be reflected in these tables.
