Radon Cluster Maintenance
Update As of 5:50 pm, Tuesday, 16 Aug 2016, the Radon cluster has been returned to service and is fully operational.
Thank you for your patience.
Update
Due to unanticipated conflicts between the upgraded scheduler and our network configuration, the outage for Radon has been extended, while we work to eliminate the conflict.
We will have a further update no later than 7:00 pm.

The Radon cluster will be unavailable beginning at Tuesday, August 16th, 2016 at 8:00am EDT, for scheduled maintenance. The cluster will return to full production by Tuesday, August 16th, 2016 at 6:00pm EDT.
During this time, Radon will have the operating system patched, the PBS resource management system upgraded, and maintenance performed on the Lustre scratch filesystem.
Any PBS jobs which request a walltime which would take them past Tuesday, August 16th, 2016 at 8:00am EDT will not start and will remain in the queue until after the maintenance is completed.
