Ohio Supercomputer Center

Downtime extended until 7AM on 12/13/17 to complete filesystem work that has taken longer than expected.
A downtime for all HPC systems is scheduled from 7 a.m. to 7 p.m. Tuesday, December 12, 2017. The downtime will affect the Oakley, Ruby and Owens Clusters, web portals, and HPC file servers. Login services, including, and access to storage will not be available during this time. 
In preparation for the downtime, the batch scheduler will begin holding jobs that cannot be completed before 7 a.m., December 12, 2017. Jobs that are not started will be held until after the downtime and then started once the system is returned to production status. 

Highlights of the downtime activities include:
  • File system checks for the project, and scratch file systems

  • Upgrades to Torque 6.1.1, and Moab 9.1.1 on all clusters

  • Deprecation of qsub -W x=GRES:RESERVATION_NAME, use qsub -l advres=RESERVATION_NAME instead. See each software page for detailed information. 

  • Users have to create new directories under /fs/scratch/project instead of /fs/scratch. See this page for detailed information. 

  • Enable support for more than 16 supplemental groups on NFS servers

  • Various other preventative maintenance tasks
