2024 ARC Summer Maintenance happening in June

By April 22, 2024 News

Summer maintenance will be happening from June 3-5. Updates will be made to software, hardware, and operating systems to improve the performance and stability of services. ARC works to complete these tasks quickly to minimize the impact of the maintenance on research.

The dates listed below are the days the work will be occurring.

HPC clusters and storage systems (/home and /scratch) will be unavailable:

  • June 3-4: for Great Lakes
  • June 3-5: for Armis2 and Lighthouse

No downtime for ARC storage systems maintenance:

  • Turbo, Locker, and Data Den will not see any interruption in service

Queued jobs and maintenance reminders

Jobs will remain queued, and will automatically begin after the maintenance is completed. The command “maxwalltime” will show the amount of time remaining until maintenance begins for each cluster, so you can size your jobs appropriately. 

Status updates

  • Status updates will be posted to the ITS website and the ARC Twitter feed
  • ARC will send an email when the maintenance has been completed.
