Center for Computational Research

Date of downtime: Tuesday, April 26, 2022

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:  

• Reboot of all cluster nodes
• Updates of front-end login nodes (vortex1/2, transfer) and OnDemand
• Panasas software update

Noticeable changes for users:

• Fisbatch is being removed.  Instructions for an alternative solution can be found here
• Users will no longer be able to SSH on a compute node running their job.  The Slurm command 'srun' should be used as an alternative.  See here
• Transfer server connections will now require being on UB or RPCI's networks (or connected to their VPN from off-campus)
• To transfer files without the VPN use the Globus service
• For SSH connections, X11 forwarding and port forwarding will be disabled

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