Center for Computational Research

Date of downtime: Tuesday, September 24, 2024

Approximate time of outage: 7am-5pm

Resources affected by downtime:

UB-HPC cluster (all partitions) 

Faculty cluster (all partitions)

Portals: OnDemand, ColdFront, IDM

Lake Effect Research Cloud: Offline for part of the day - Back online - please contact CCR Help if your instances have not returned to normal after the outage

What will be done:  

• Electrical work in machine room requiring power outage of all compute nodes and other services
• Reboot of all cluster nodes
• Updates of front-end login nodes (login1/2, vortex-future) to Ubuntu 24
• Update of OnDemand
• Update of apptainer
• Infrastructure services updated
• Slurm upgrade
• Removal of anaconda3 module from ccrsoft/2023.01 - Anaconda has not been supported by CCR for some time and due to changes in the licensing terms we are now legally obligated to remove it from our systems
• Removal of /util/academic, /util/common, /util/industry, /util/software/legacy from CCR systems

Changes to be aware of:

• module load anaconda3 will no longer work
• Since January 2023, we have moved forward with sunsetting the ccrsoft/legacy software environment (everything installed in /util/common, /util/academic, & /util/industry).  This software environment was removed from our systems in June so users can no longer run "module load ccrsoft/legacy" and access any of the previous generation of software modules.  However, there may be users who installed software in their own project or home directories that depended on software within the /util structure.  Though it is unlikely this software is still working due to other considerable upgrades done on CCR's systems in the last year, there is always the possibility this final change will break some workflows.  As we've said for the last 18 months, please ensure that your software works without anything in /util so that you do not experience any issues after this downtime.
• If you are using one of the legacy containers provided by CCR in June as a temporary work around, these will also be going away as they depend on software installed in /util.
