HPCC Service Status

Development Node Configuration Change

Mon, 13 Apr 2026 13:00:00 +0000

On Tuesday, April 14th, at 8:00PM, we will be applying a configuration change to the development nodes in order to increase system stability. This change will reserve a portion of memory solely for system processes. This will mitigate situations where high memory demand could otherwise cause development nodes to become unresponsive. This configuration change is expected to be non-disruptive, however, if you encounter any issues or have any questions, please contact us

HPCC Scheduled Maintenance

Thu, 09 Apr 2026 15:00:00 +0000

The HPCC will be unavailable on Thursday, May 7 starting at 5AM for regularly scheduled maintenance. No jobs will run during this time.

Jobs that will not be completed before this date will not begin until after maintenance is complete. For example, if you submit a four day job three days before the maintenance outage, your job will be postponed and will not begin to run until after maintenance is completed.

If you have any questions, please contact us

Research File System Quota Troubleshooting Beginning 4/9/2026

Mon, 06 Apr 2026 19:00:00 +0000

Beginning Thursday, April 9, 2026, we will be working with our vendor to troubleshoot a technical issue with the Research Space quota system. No outage is anticipated; however, you may notice periodic slowdowns while we troubleshoot this issue. This message will be updated as troubleshooting continues, and will be resolved once the quota system is returned to normal operation. If you experience any issues accessing a Research Space or Project directory during this time, please open a ticket.

Operating System Updates Beginning 4/1/2026

Wed, 01 Apr 2026 13:30:00 +0000

Over the next several weeks, ICER will be performing minor operating system updates across all nodes in the HPCC. During this time, users may notice longer queue times and some nodes unavailable in Slurm while they are being updated. Once the updates are complete, nodes will be returned to service and jobs will continue to schedule and run. Because these are minor updates, the software and module system is unaffected. No issues have been identified in initial testing, but please open a ticket if you experience any issues.

Legacy Software Module Maintenance Tuesday 03/31/26

Thu, 26 Mar 2026 14:45:00 +0000

On Tuesday, 31 March 2026 we will be changing the backend for legacy (CentOS 7) versions of our software modules. This will require remounting the legacy software modules across the cluster. If you are using the legacy CentOS-7 container to run workloads on this date, you may see an interruption of your work.

Scheduler Reboot at 8:00PM on 3/9/26 - RESOLVED

RESOLVED 8:02PM: The scheduling server is back online.

At 8:00PM on Monday, March 9th, the SLURM scheduling server will go offline for a reboot. This reboot is necessary to increase the host’s memory and improve stability. The scheduler is expected to be offline for less than 15 minutes. During this time, jobs may not be submitted and scheduler specific client commands will not work (e.g. squeue, sbatch, etc). Running jobs will not be affected. If you have any questions about this outage, please contact us.

Open OnDemand terminal issue in Firefox 148

Thu, 26 Feb 2026 14:00:00 +0000

RESOLVED 3/3: OnDemand has been updated to fix this bug. You may need to restart your OnDemand session to realize this change. You can reset your session by clicking here.

The latest update to the Firefox web browser, version 148, has caused a failure in the Open OnDemand terminal. Users will see a white screen instead of the expected terminal view. We are waiting on the Open OnDemand development team to produce a patch. In the meantime, please use a different web browser, or connect to the HPCC terminal using an SSH client. A guide for using SSH clients is available in our documentation. We will update this post once more information is available.
