Our maintenance on Chinook to address the slowdown on multi-node jobs is now complete. As a result of this change in multi-node jobs the following should be added to your job submission script:

ulimit -l unlimited
ulimit -s unlimited

If these commands are not added there is a possibility that your job may fail.

***This outage has been extended.***

Please note the following changes:

May 11 2017 - 3:00pm to May 12 2017 - 9:30am

The $CENTER1 Lustre filesystem became temporarily unavailable to the Chinook compute nodes on May 11th around 3pm AKDT, causing some submitted jobs to fail immediately. To resolve this issue the job partitions were taken down, and any submitted jobs were placed into a waiting queue until the partitions were brought back online.

Any jobs that were in the process of running during that timeframe should be unaffected.

Mar 22 2017 - 9:00am to 5:00pm

Chinook will be taken offline for a short time on March 22, 2017, at 9:00AM AKDT to allow for the replacement of $CENTER on Chinook with a new Lustre filesystem. The new filesystem will be assigned the environment variable $CENTER1.
