A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, December 19, 2023. The downtime will affect the Pitzer, Owens and Ascend Clusters, web portals, HPC file servers, and state-wide licenses. 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., December 19. 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.
Highlights of the downtime activities include:
- Changes to the Infiniband network topology in preparation for the new cluster
- Update of the Slurm batch system
- Firmware and OS updates on critical servers and network switches
- Regular systems maintenance
