System Downtime December 13, 2022

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, December 13, 2022. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, and HPC file servers. MyOSC (https://my.osc.edu) and state-wide licenses will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., December 13, 2022. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.

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.
