Posted on August 1, 2018, at 12:35 PM:

We will have rolling reboots of Owens and Ruby clusters including login and compute nodes, starting from 8 AM Monday, August 6, 2018. This rolling reboot is to make the latest CUDA 9 and dependent software available with the updated device driver, for the preparation of the software refresh at the end of this August. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on Owens and Ruby clusters. Oakley cluster is not included in the rolling reboot. 

We apologize for any inconvenience this may cause you. Please contact if you have any questions.
