Quest Analytics Nodes, the Genomics Compute Cluster (GCC), the Kellogg Linux Cluster (KLC), and Quest OnDemand, will be unavailable for scheduled maintenance starting at 8 a.m. on Monday, June 22, and ending at 5 p.m. on Friday, June 26.
Service Improvements: • Faster compute time due to improved intra- and inter-node GPU communication. • Faster job recovery (via expedited job requeue on node failure) and improved job monitoring (via new job filtering options based on runtime) through scheduler upgrade to Slurm v25.11. • FastX4 will be available to provide a more reliable and secure remote desktop experience (FastX3 desktop client can still be used to connect to Quest after the maintenance). • Required patching, software upgrades, and equipment maintenance.
Impact on Quest and Globus Users: • Jobs with a wall time extending into the maintenance period will not run. (These jobs will receive a "ReqNodeNotAvail, Reserved_for_maintenance" message). • Access to Quest (including Quest Analytics Nodes, GCC, and KLC) will be unavailable. • Jobs and processes running when the maintenance begins will be canceled. • Globus will not be available to transfer data to/from Quest or FSMResFiles. • The expiration dates of all user files in the Quest global scratch space will be extended to 30 days following the maintenance.
This scheduled maintenance affects: Research Technologies and Support (Quest Analytics Nodes, Quest High-Performance Computing Cluster (HPCC) (Server Management)).
