Owens
Rolling Reboot
We will have rolling reboots of all three clusters (Owens, Ruby, and Pitzer) including login and compute nodes, starting from 9:30 AM Wednesday, June 05, 2019. The rolling reboots will address the caching problems on the file systems. 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 oschelp@osc.edu if you have any questions.

CHANGE OF DEFAULT MATLAB VERSION
OSC is changing the default version of MATLAB on all clusters from R2018a to R2018b effective Friday, April 26th. Several bugs exist in R2018a that have been addressed in R2018b.
