Recently resolved problems

  • 2017-03-06 07:30 - 08:10: Campus-wide power outage affecting both NSC computer rooms and offices. Most systems went down, all running compute jobs failed. Most systems back up before lunch. Triolith and Gamma kept offline to perform maintenance that was originally scheduled for Thursday March 9th.

  • 2017-01-22 03:45 - 2017-01-23 16:00: A problem in NSC Centre Storage prevented starting new jobs and accessing login nodes. Access to login nodes restored approx. 2017-01-22 20:20. Job starts resumed 2017-01-23 16:00. See this email thread for more information.

Planned maintenance

  • none

Planned hardware changes

  • The part of Triolith available to SNAC projects will shrink from 1536 nodes to 960 nodes on April 1st, 2017. This is a result of the delay in funding a replacement system. By reducing the number of nodes we can keep the rest of the system running at least until October 31st, 2017 (an extension until December 31st 2017 is not decided yet, but very likely). The size of new projects will be adjusted accordingly.
  • The LiU-only HPC service using the Gamma cluster will move to a different computer room (still on the LiU Valla Campus) on April 1st, 2017 to make room for a new MET Norway HPC system. The LiU HPC ("Gamma") service will then continue either as a separate system or as a separate partition in Triolith.
