We will have a rolling reboot of login and compute nodes of Owens cluster starting from Monday, April 16, 2018.

Users may have been experiencing job failures on Owens cluster since April 16, 2018

Rolling reboot of compute and login nodes of all clusters, starting from Wednesday morning, March 22, 2017


4:56PM 3/28/2017 Update: The rolling reboots of all systems are completed. 

All compute nodes and login nodes of Owens, Oakley, and Ruby clusters will need to be rebooted for kernel upgrades because of security vulnerabilities. The rolling reboot is scheduled starting from Wednesday morning, March 22, 2017. This won't affect any running jobs, but users may experience longer queue wait time than usual on all systems. Users might also experience difficulties with access to our systems or automatic termination of the sessions on the login nodes when login nodes are rebooted. 

We really apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions
