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.

2022 Storage Service Upgrades

In October 2022, OSC retires the Data Direct Networks (DDN) GRIDScaler system deployed in 2016 and expands the IBM Elastic Storage System (ESS) for both Project and global Scratch services. This expands the total capacity of Project and Scratch storage at OSC to ~16 petabytes with better performance.
