A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, May 13 2025. The downtime will affect the Pitzer, Cardinal and Ascend Clusters, web portals, the state-wide licenses and HPC file servers. MyOSC (the client portal) 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., May 13. 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.

Ascend with additional 250 Dual GPU nodes has been launched and are open to all users. For detailed information on how to access and optimize these resources, please visit our Ascend Page: https://www.osc.edu/content/ascend

The early user program for the next-generation resources now available on the Ascend cluster begins today, March 3, and will run through Monday, March 31. Check this page for more information: https://www.osc.edu/content/next_gen_ascend_1/next_gen_ascend_early_user_program

The core and node labels on the Classroom app (class.osc.edu) incorrectly displays as '0', regardless of the requested number of cores for a job. While this label is incorrect, the job is still allocated the correct number of cores as intended. We are actively addressing this issue and plan to deploy a fix later.
