November 2021: Monthly Maintenance Downtime (11/30/21)

Date of downtime: Tuesday, November 30, 2021


Approximate time of outage: 7am-5pm


Resources affected by downtime:

UB-HPC cluster (all partitions) 

Industry cluster (all partitions )

Faculty cluster (all partitions)

Portals: WebMO, OnDemand


What will be done:  

  • Operating system updates and reboot of all cluster nodes, front-end login nodes (vortex1/2, transfer) and OnDemand
  • OnDemand software update and migration to a large virtual machine.  This should help with the reports of slowness we've received of late.
  • Slurm update (tentative)
  • LMOD update (tentative)


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