Cardinal

Cardinal Software Environment

The Cardinal cluster is now running on Red Hat Enterprise Linux (RHEL) 9, introducing several software-related changes compared to the RHEL 7 environment used on the Pitzer cluster. These updates provide access to modern tools and libraries but may also require adjustments to your workflows. Key software changes and available software are outlined in the following sections.

Cardinal SSH key fingerprints

These are the public key fingerprints for Cardinal:

cardinal: ssh_host_rsa_key.pub = 73:f2:07:6c:76:b4:68:49:86:ed:ef:a3:55:90:58:1b
cardinal: ssh_host_ed25519_key.pub = 93:76:68:f0:be:f1:4a:89:30:e2:86:27:1e:64:9c:09
cardinal: ssh_host_ecdsa_key.pub = e0:83:14:8f:d4:c3:c5:6c:c6:b6:0a:f7:df:bc:e9:2e

Batch Limit Rules

The PBS compatibility layer is disabled on Cardinal so PBS batch scripts WON'T work on Cardinal, though it works on the Pitzer cluster. You also need to use sbatch (instead of qsub) command to submit jobs. Refer to the Slurm migration page to understand how to use Slurm. 

Memory limit

It is strongly suggested to consider the memory use to the available per-core memory when users request OSC resources for their jobs.

System Downtime August 6 2024

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 6 2024. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. There will be a short outage of the state-wide licenses; MyOSC (the client portal) will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., August 6. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.
