Cheyenne downtime scheduled for September 12

The Cheyenne cluster will be unavailable Tuesday, September 12, from 8 a.m. until noon MDT  to allow CISL staff to perform important system updates.

A system reservation will be put in place on batch jobs Monday afternoon. Jobs submitted with specified job times that overlap the reservation period will remain on hold until the system is restored to service. Running jobs that have not finished when the outage begins may be killed and need to be resubmitted after the system is restored to service. Users are advised to take this into account before submitting long jobs after 8 p.m. on Monday.

We apologize for any inconvenience this might cause. Users will be informed via the CISL Notifier service when the system is returned to production.
