Derecho supercomputer delivery delayed to December

July 11, 2022

Hewlett Packard Enterprise (HPE) has notified CISL that delivery of the new Derecho supercomputer is now being delayed until December 2022. This most recent delay is the result of the U.S. Government having rated another order as a higher priority, pursuant to Section 101(a) of the Defense Priorities and Allocations System (DPAS). HPE has a number of DPAS-rated orders and is legally obligated to comply.

While NCAR and HPE are working on an official revised schedule, we expect that the latest delay means that Derecho will not enter production until roughly April 2023. The previously selected Accelerated Scientific Discovery (ASD) projects will have access to the machine for its first two months, after which other projects will be granted access. The delay also means that users can expect Cheyenne to be in operation through approximately September 2023. We will provide more specific information once the schedule is formalized.
