Center for Computational Research

Date of downtime: Tuesday, April 30, 2024

Approximate time of outage: 7am-5pm

Resources affected by downtime:

UB-HPC cluster (all partitions) 

Faculty cluster (all partitions)

Portals: OnDemand

What will be done:  

• Reboot of all cluster nodes
• Updates of front-end login nodes (login1/2, vortex1/2, vortex-future) and OnDemand
• Infrastructure services updated
• Changes to OnDemand apps:
  • Update to MATLAB app to allow for better window management and GPU access
  • Viz Node (CUDA/OpenGL) desktop app will be removed as this is no longer necessary
  • Users can run hardware accelerated graphics applications on any GPU node in the center
  • Users may choose the "viz" partition and QOS to access compute nodes reserved for visualization activities.  This partition is limited to 24 hour maximum walltime and only 1 session per user.  Using this partition may result in less wait times but this is dependent on demand for GPU nodes.
