Cheyenne supercomputer released to user community

March 17, 2017

The Cheyenne supercomputer is now available to all users and projects with Cheyenne allocations, following several months of intensive work by many CISL groups.

Production jobs for Accelerated Scientific Discovery (ASD) projects will continue to have priority on Cheyenne through the end of March. Other users can now work on porting code, preparing job scripts, and migrating files as needed to the new GLADE scratch space.

The GLADE file system is in transition to expand its capacity and to support work on Cheyenne, Yellowstone, Geyser, and Caldera. See our GLADE documentation for details.

Cheyenne has fewer queues than Yellowstone initially because of limitations with the current version of the PBS job scheduling system. Users will have access to the “regular,” “capability,” and “share” queues. An “ampsrt” queue is provided for AMPS project jobs. Additional queues, such as “premium” and “economy,” will be added as the desired functionality becomes available. See the Cheyenne queues web page for more details.
