Cheyenne has been returned to service

August 4, 2023

This week’s Cheyenne maintenance activities are complete.  The machine was returned to production status ahead of schedule at 1PM Thursday, August 3.  Notably, repairs to the InfiniBand high-speed network were performed as well as cooling system maintenance.  CISL engineers have verified functionality, with particular emphasis on large jobs that were disproportionately impacted by the previous network instability.
