• Blue Waters Scheduled Maintenance Update

  Created by: jenos 2018-07-13 11:57:54 (Channels: scheduledoutages|systemnotices|softwareupdate)

  Blue Waters Users,

  Please note the following scheduled maintenance update:

  The scheduled maintenance for CUDA 9.1 deployment on Blue Waters has been expanded to a near full system service outage that will span 13 hours on Monday July 16th, from 9am to 10pm. This adjustment will eliminate the need for an additional scheduled maintenance period. To maximize availability, login nodes and filesystems will remain in service during the maintenance. The expanded activities include hardware maintenance, operating system software update roll ups, and some preventative maintenance to maximize future stability. Major changes are still the Programming Environment and CUDA 9.1 depoloyments originally planned.

   

  ---

  A new Programming Environment will be installed as a non-default and will be made default after a test period and subsequent announcement.

  CUDA notes: XK nodes will receive CUDA update (and associated driver) to version 9.1.  CUDA 7.5 will still be available as non-default.  CUDA 7.5 binaries have tested successfully in the CUDA 9.1 environment, but it may be necessary to recompile.  sm_20 and compute_20 are deprecated in any build or makefile setup.  People should use sm_35 and/or compute_35 to best match our Kepler K20x GPUs.

  Interim updates will be posted on the Blue Waters System News

   

  Please plan accordingly.
