NWSC and HPC systems maintenance downtime planned for May 9-13

March 18, 2022

NCAR’s HPC resources will be unavailable to users May 9-13 while CISL staff perform annual system and facility maintenance at the NCAR-Wyoming Supercomputing Center (NWSC). The work includes a number of HPC system software updates in addition to power and cooling system maintenance tasks. Progress will be communicated through Notifier emails during the week.

Software upgrades are planned for all Cheyenne, Casper, and JupyterHub login and computing resources; the GLADE, Quasar, and Stratus storage resources; and the HPC/storage systems network. CISL staff will verify their functionality before releasing the systems to the user community.

Any jobs that are queued when the downtime begins will be retained for execution when the systems return to service.
