HPC maintenance scheduled for January 7 – 9

By November 30, 2016Flux, General Interest, News

To accommodate upgrades to software and operating systems, Flux, Armis, and their storage systems (/home and /scratch) will be unavailable starting at 9am Saturday, January 7th, returning to service on Monday, January 9th.  Additionally, external Turbo mounts will be unavailable 11pm Saturday, January 7th, until 7am Sunday, January 8th.

During this time, the following updates are planned:

  • Operating system and software updates (minor updates) on Flux and Armis.  This should not require any changes to user software or processes.
  • Resource manager and job scheduling software updates.
  • Operating system updates on Turbo.

For HPC jobs, you can use the command “maxwalltime” to discover the amount of time before the beginning of the maintenance. Jobs that cannot complete prior to the beginning of the maintenance will be able to start when the clusters are returned to service.

We will post status updates on our Twitter feed ( https://twitter.com/arcts_um ) and send an email to all HPC users when the outage has been completed.
