• Blue Waters Scheduled Maintenance: Return to Service

  Created by: gbauer 2018-07-16 19:43:38 (Channels: scheduledoutages|systemnotices|softwareupdate)

  Blue Waters Users,

  Blue Waters has been returned to service after a security update and programming environment update. CUDA 9.1 is now available as the default cudatoolkit but with gcc/4.9.3 remaining as the default GNU compiler. The default programming environment otherwise did not change to allow for an extended transition to the newer programming environment.

  For a complete discussion of the changes to the Programming Environment please see the Programming Environment (PE) Changes  portal page.

  This is an extensive programming environment update and as such there will be issues we did not discover in advance. Please report issues to help+bw@ncsa.illinois.edu.

  A new Programming Environment was 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.
