Update: Cheyenne access to be limited as stability issues continue

August 6, 2019

Cheyenne continues to experience system stability issues, and CISL staff are engaging vendors to troubleshoot the problems. Meanwhile, to ensure that this week's CESM tutorial succeeds for the 80 on-site attendees, CISL will be limiting access to the Cheyenne compute nodes to only tutorial attendees during the hands-on sessions on Tuesday, Thursday, and Friday afternoons. All standard queues will be halted; running jobs will finish and other submissions will remain queued until the tutorial is finished for the day. Casper will remain fully available to all users throughout the week.

CISL is escalating support from HPE and Mellanox to resolve the system issues after the CESM tutorial ends on Friday. More details on the vendors' plans will be provided as soon as they are finalized.
