June 3rd Update: Major HPC Facility Maintenance

June 3, 2025

NWSC Facility Maintenance is continuing throughout the week.

Initial shutdown activities were completed yesterday.  We experienced a number of challenges with temporary cooling units that have impacted our original system continuity plans.  At this point home, work, Campaign Storage file systems remain available and can be accessed through the Casper login nodes.  Currently, no Casper compute resources are available for general job submission, though we will attempt to make some resources available if data center conditions permit.

The scratch filesystem has been shut down to reduce thermal load, along with the Derecho login nodes, Jupyter Hub, and the Stratus object storage system. This disruption was a departure from the original plan but required to triage thermal challenges.

 All Derecho compute nodes and the Quasar tape archive will remain down throughout the week as originally planned.
