7:00am to 5:00pm


The Ohio Supercomputer Center has scheduled a downtime for all HPC systems starting Tuesday, May 19th, 2015, beginning at 7 a.m and scheduled to finish by 5 p.m. The downtime will affect the Glenn, Oakley, and Ruby clusters, web portals, and HPC file servers. Login services and access to storage will not be available during this time.
In order to quiesce the system for an orderly shutdown the batch scheduler will begin holding jobs that cannot complete before 7 a.m. May 19th.  Jobs that are not started will be held until after the downtime and then started once the system is returned to production status.
Departmental clusters that we are administering will not be affected by this outage.
Highlights of the downtime activities:
  • Routine OS patches, updates, firmware updates and system reboots
  • NVIDIA driver upgrade to support CUDA 7
  • Upgrade to Luste server to fix server crashes
  • Migration to new database servers
