July 2020: Maintenance Downtime (MOVED to 8/4/20)

Date of downtime: Tuesday, August 4, 2020  NOTE: The July & August downtimes have been moved ahead one week

Approximate time of outage: 7am-5pm

Resources affected by downtime:

UB-HPC cluster (general-compute, debug, viz, largemem, and gpu  partitions) 

Industry cluster (compute, scavenger partitions)

Faculty cluster (all partitions)

Portals: WebMO, OnDemand

What will be done:  

  • Operating system updates on front end servers and OnDemand
  • Reboots of all cluster nodes and front end servers
  • Slurm authentication via PAM is changing - please contact CCR Help if you get any authentication errors when jobs launch - Technical Details (see UsePam section)
  • limits.conf changing - to allow for core dump creation for debugging purposes - core dumps can fill up the node.  Please ensure you clean up your files before your job exits!  If your job fails, contact CCR Help to clean up the node manually
  • See this page for modules being deprecated

Jobs will be held in queue during the maintenance downtime and will run after the updates are complete.
