upcoming quarterly maintenance – 4/19/2011

This entry was posted by on Monday, 4 April, 2011 at

Just a reminder folks – our quarterly maintenance is coming soon.

I’ve lowered the maximum allowed time for jobs to 14 days, and will continue to decrement as we approach the maintenance window.  This only applies to newly submitted jobs.  Jobs that haven’t completed by the morning of 4/19 will be cancelled.

Major items on the list are the application of standard OS updates from RedHat, updating and normalization of firmware in Infiniband host adapters, and rebooting of the main Infiniband switch to complete the transition to a software based subnet manager.

***** IMPORTANT *****

Please use the TestFlight cluster (announced here http://blog.pace.gatech.edu/?p=3151) to test your codes.  The updates have already been applied there, and we would appreciate any feedback (positive or negative) you have.

***** IMPORTANT *****

Expect all clusters to be offline for the day. This includes:

  • Aryabhata
  • Athena
  • Atlantis
  • Atlas (RedHat updates will not be applied)
  • BioCluster
  • Cygnus
  • FoRCE
  • Joe
  • TestFlight Cluster (RedHat updates already applied)
  • Legacy PACE Community Cluster (RedHat updates will not be applied)
  • Uranus
