Deadline September 14 for university large-scale allocation requests

August 9, 2021

CISL is now accepting large-scale allocation requests from university-based researchers for Cheyenne resources and the Casper data analysis and visualization cluster. Those requests are due September 14.

As recently announced, delivery of the new Derecho system has been delayed by four months because of the global chip shortage. As a result, the first large university allocation requests for Derecho will be reviewed in the spring. Also because of the delay, Cheyenne will now be kept in service through December 2022. CISL will support transfers of allocations from Cheyenne to Derecho prior to Cheyenne being decommissioned.

Researchers are encouraged to review these instructions before preparing their large-scale allocation requests.

Note that CISL is separately accepting requests for Accelerated Scientific Discovery (ASD) projects to be the first to run on Derecho; ASD proposals are due September 3. See these instructions specific to ASD requests.

In addition to requesting computing allocations, university projects can request long-term space on the NCAR Campaign Storage resource. Campaign Storage has no default minimum amount; users are asked to justify the amount requested. The CISL HPC Allocations Panel continues to closely scrutinize data management plans and storage requests, especially when proposals request a substantial portion of the storage capacity available to allocate.

At the fall meeting, CISL will allocate up to 220 million core-hours on Cheyenne, up to 3 PB of Campaign Storage space, and up to 200 TB of GLADE project space. Large allocations on Cheyenne are those requesting more than 400,000 core-hours. CISL accepts requests from university researchers for these large-scale allocations every six months.
