On Friday, May 15, 2026, we will be upgrading the services that provide NFS and SMB access to research space directories on the HPCC. No downtime is expected during these upgrades, but periodic pauses or slowdowns with NFS or SMB file transfers may be noticed during the upgrade process. We will update this blog with more information as soon as the upgrades are complete.

Due to short-term staffing issues we anticipate that help desk response times will be somewhat longer than usual. We strive for an initial response to all queries within one business day but anticipate that a more realistic response time in the near future will be 2-3 business days. We will prioritize urgent requests to the greatest extent possible. We apologize for any inconvenience this may cause, and thank you in advance for your patience.

The high memory capacity nodes, vim-000, vim-001 and vim-002 are back online to support specific research computing needs. They support either 2.93 TB (vim-000, 001) or 5.86 TB (vim-002) of random access memory (see our documentation on cluster resources for details). These nodes are available via a separate partition and are not in the general queue. Please see our documentation on SLURM constraints for usage.

Following the recent downtime, the amount of memory available for jobs on nodes has been tuned to increase system stability. On all nodes except intel18, the amount of memory available to jobs has been reduced by 5GB. A full list of node types and the memory available to jobs can be found in our documentation. This adjustment will help prevent unexpected lockups and reboots of nodes during times of high memory utilization.

Jobs scripts that request the maximum amount of memory available on a particular node type may need to be adjusted following this change. If you have any questions about this change, please contact us.
