Rolling reboot of Owens and Pitzer starting from July 11, 2022

We will have rolling reboots of Owens and Pitzer clusters including login and compute nodes, starting from 9AM Monday, July 11, 2022, to perform OS updates to address CVE-2022-1966 (https://access.redhat.com/security/cve/CVE-2022-1966). The rolling reboots won't affect any running batch jobs, but users may experience longer queue wait time than usual on both clusters. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.

OSC Classroom Support

CLASSROOM RESOURCES FOR DISTANCE LEARNING If your class has lost or limited access to computer labs, the Ohio Supercomputer Center might be able to help by providing no-cost access to cloud computing resources. Classes and workloads of any size can gain access. OSC's web-browser interface to its substantial Linux computer systems provides novice users with virtual desktops preloaded with applications, such as MATLAB, RStudio, or Jupyter Notebook. As an example, an OSU undergrad statistics class recently used iPads to remotely access RStudio on OSC systems.
