Cheyenne expected to remain unavailable today

November 15, 2017

The Cheyenne cluster is expected to remain unavailable today, Wednesday, Nov 15.  At this time there is no estimate for when the system will be restored to service.

CISL staff are continuing to track down the source of the system’s instability and several hardware components have been replaced or repaired. The vendors HPE and Mellanox are working closely with the system administrators to resolve the problems as quickly as possible.

CISL will inform users through the Notifier service on any significant updates and again thanks you for your patience.
