Rolling Reboot of Owens Nodes will begin September 11 at 9am

In order to upgrade the kernel, we will conduct a rolling reboot of all Owens nodes. This will begin at 9 a.m. on September 11 and continue until all nodes have been rebooted. The login nodes will be rebooted first.This rolling reboot won't affect any running jobs, but users may experience longer queue wait times than usual on the Owens cluster. Please contact if you have any questions.

HOWTO: submit homework to repository at OSC

This page outlines a way a professor can set up a file submission system at OSC for his/her classroom project.
