Reminder: Cheyenne is unavailable this week

July 13, 2020

The Cheyenne supercomputing system is unavailable this week to allow CISL staff and external contractors to perform power infrastructure repairs at the NCAR-Wyoming Supercomputing Center. CISL high-performance computing specialists and HPE engineers will also perform several repairs and updates while the system is down. The maintenance began at 5 a.m. MDT today. The system is expected to be returned to service on Saturday, July 18. 

The Casper cluster, GLADE and Campaign Storage file systems, HPSS, data-access nodes, and remote access services FastX and VNC will remain available throughout the week except for Tuesday, July 14, from 7 a.m. until approximately 7 p.m. While Cheyenne is unavailable, users can access GLADE by logging in to casper.ucar.edu. CISL’s pre-production implementation of the JupyterHub platform on Cheyenne and Casper will be available after Cheyenne is restored to service.
