Pitzer

A downtime for all OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Wednesday, March 31, 2021. The downtime will affect the Pitzer and Owens Clusters, web portals, state-wide licenses, and HPC file servers. Login services will not be available during this time, including MyOSC. In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., March 31, 2021. 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.

We will have rolling reboots of Pitzer cluster including login and compute nodes, starting from Feb 03, 2021. The rolling reboot is to update BIOS for urgent security updates as well as memory bug fixes. The rolling reboots won't affect any running jobs, but users may experience longer queue wait time than usual on the cluster. User will also expect a ~10 minute outage of login nodes at about 9AM Feb 05, 2021. We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.

There has been a recent to the batch submission process where a job needs to specify a project account at submission. If using https://ondemand.osc.edu then enter a project account in the account or project fields. See https://www.osc.edu/supercomputing/batch-processing-at-osc/job-scripts for more info.
