[intrepid-notify] ALCF Weekly Updates - October 13

[ALCF User Services]

*** /home Intrepid File System Changes Bring Improvements ***
The November 28 switch to the new /home file system on Intrepid brings several improvements, including a faster file system with more space and more resiliency to failure. Beginning next week, we will begin a re-sync of the new /home file system from the current one in the background. Once synchronization is verified, we will switch over on November 28. The process should be invisible to users. For more information on storage changes, visit https://wiki.alcf.anl.gov/index.php/File_Systems#2011_Intrepid_Storage_Changes. 

*** Maintenance Monday: October 17 ***
Routine maintenance kicks off at 9 a.m. CDT (14:00 UTC) on Monday, October 17, for Intrepid, Eureka, Surveyor and Gazooks. The systems will be unavailable during maintenance. Please watch the "notify" lists for projected and actual release times.

*** Environment Changes for Script Jobs Coming October 17 to Intrepid ***
An upcoming change to Cobalt will change the environment that script mode jobs on Intrepid receive. Script jobs will start up with the submitting user's non-interactive login environment at the time the job is started. Once the change is live, users should check that the environment variables in their script-mode jobs are set to expected values. This change is expected to go live on Intrepid on October 17. These changes are already live on Surveyor, if you wish to test your scripts. If you were already sourcing your environment in your script jobs, then this step will not be necessary after this change. For more information, visit https://wiki.alcf.anl.gov/index.php/Running#Script_environment.

*** Switch to Challenger Means Procedural Changes for Users ***
Challenger (the ALCF's new rack of Blue Gene/P) will be online soon. Once Challenger is online, the prod-devel queue on Intrepid will be retired and jobs formerly run there will be run on Challenger. To help smooth the transition to Challenger, please continue to watch for additional information and training opportunities.
