Completed: Quarterly Cluster Maintenance Tuesday October 25 | crc.pitt.edu

Dear CRC User Community,

We have completed our quarterly maintenance and have returned the clusters to production.

The key changes to the CRC clusters are the following:

  • Storage Systems updates – Improved performance of iX with cache upgrades
  • SLURM Workload Manager –  Update to newest version (22.05)
    • Due to incompatibility between the previous and the upgraded Slurm, we had to purge all previously queued jobs. You will need to resubmit your jobs. Our apologies for any inconvienence this may cause.
  • Decomissioned the titanx, k40, and scavenger partitions on the GPU cluster

We are working out some lingering issues with how Jupyterhub sessions are behaving after the SLURM upgrade, the service is down and will be intentionally unavailable until we can resolve the issue.

Beyond this, if you encounter post-maintenance problems, please log in and submit a help ticket.

–CRC Team
