When you obtain a new HPC account, you will be provided with storage. The shared storage (/home, /groups, /xdisk) is accessible from any of the three production clusters: Puma, Ocelote and ElGato. The temporary (/tmp) space is unique to each compute node.
All University of Arizona Principal Investigators (PIs; aka Faculty) that register for access to the UA High Performance Computing (HPC) receive these free allocations on the HPC machines which is shared among all members of their team. Currently all PIs receive:
How to Find Your Remaining Allocation
You can view your remaining allocation using the HPC User Portal at https://portal.hpc.arizona.edu/portal/.
The command va will display your remaining time on the terminal.
You can use this time on either the standard nodes which do not require special attributes in the scheduler script, or on the GPU nodes which do require special attributes. The queues are set up so that jobs that do not request GPU's will not run there.
Slurm and PBS Batch Queues
The batch queues on the different systems have the following memory, time and core limits.
# of Compute Nodes
Max Wallclock Hrs per Job
Largest job (max cores)
|Total cores in use per group|
Largest job (max memory GB)
Max # of Running Jobs
|Max Queued Jobs|
*** This limit is shared by all members of a group across all queues. So you can use the system 2016 core limit by one user on the standard queue or share it across multiple users or queues.
