We will have rolling reboots of three clusters (Owens, Ruby, and Oakley) including login and compute nodes, starting from 8 AM Tuesday, June 19, 2018. The rolling reboots will address recent Kernel vulnerabilities patched by RedHat. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster.
We apologize for any inconvenience this may cause you. Please contact firstname.lastname@example.org if you have any questions.
