Cluster Maintenance

June 16, 2015  5:00am – 6:00pm
Conte, Hammer, Hansen, Rice, Rossmann, Snyder

Software upgrades on Rice Cluster have been completed by 7:30pm. It is now open for access by early adopters. Please let us know if you see any issue with the cluster.


Maintenance on Snyder, Rossmann, Hansen, Hammer, and Conte has been completed and these clusters are back in production.

Our systems team is still investigating some storage issues on Rice nodes. Rice is expected to be available by 9:00pm today. Please check the website later for updates.


The Conte, Hammer, Hansen, Rice, Rossmann, and Snyder clusters will be unavailable beginning at Tuesday, June 16th, 2015 at 5:00am, for scheduled maintenance. The clusters will return to full production by Tuesday, June 16th, 2015 at 6:00pm.

The downtime is necessary to replace the chilled water filter system in the MATH building data center. During this time, Conte, Hammer, Hansen, Rice, Rossmann, and Snyder will have the operating system patched and maintenance performed on the Lustre scratch filesystems. Additionally, Conte's interconnect drivers will be updated.

Any PBS jobs which request a walltime which would take them past Tuesday, June 16th, 2015 at 5:00am will not start and will remain in the queue until after the maintenance is completed.
