Stokes and Newton will be taken down per our bi-annual routine maintenance cycle during mid-December. Specifically, the clusters will be unavailable from Sunday, December 15 through Sunday, December 22.
The primary objectives during this downtime is to upgrade SLURM and our module system.
Recall that we now routinely bring the system down twice a year, once in late Fall and once in late Spring. We will keep the users notified in advance of such downtimes, but we recommend you build such expectations into your workflow. Though we anticipate no data loss during this time, it's never a bad idea to backup your materials. So we suggest you use this opportunity to copy salient data and code off of Stokes and Newton prior to the downtime.
Power loss in research park, ARCC outage

Last night (Thursday, September 26) at 11:30p, a commercial power loss in research park caused an outage in the Partnership buildings, where our clusters reside. The outage lasted 2.5 hours. The good news is that our system functioned precisely as designed: Our UPS held the load of the cluster for the designed length of time, and the core infrastructure elements (e.g., file system, infiniband backbone) were protected the entire time via generator.
But the bad news is that the length of the outage exceeded our UPS's designed limits, which means that almost all compute nodes lost power. All jobs on Stokes, and many jobs on Newton were lost. We apologize for the inconvenience.
The clusters are back up and accessible now. Queued jobs have deployed and are running.
