Additional storage:
- /xdisk/netid - 200GB to 1TB available on request. The time limit is 45 days with one extension. This allocation is deleted after 45 days if no extension is requested. There are directory level quotas so any files in this directory count against this quota not matter who created it. The data is not backed up.
- /rsgrps/netid - rented/purchased space (no backups)
| Tip |

We strongly recommend that you do some regular housekeeping of your allocated space. Millions of files are hard to keep organized and even more difficult to migrate. Archiving or using a tool like tar will help keep our disk arrays efficient. |

/extra is something new with Ocelote. When you log in to Ocelote for the first time, an allocation of 200GB will be created for you. It takes an hour or two to show up, and then it is permanent. Remember that it is not backed up like /home.
Job Limits
Job Time Limits
Each group is allocated a base of 24,000 hours of compute time, this allocation is refreshed monthly. The allocation can be used on either the htc/cluster/smp clusters or on the new cluster, Ocelote., or a combination.
ElGato has a different allocation method of time as it is funded through an NSF MRI grant with usage time provided for campus researchers outside of the grant recipients. Reference the www.elgato.arizona.edu web site.

, /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.
Job AllocationsAll 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:
