CISL is now accepting allocation requests from university-based researchers for the new Derecho system and the Casper data analysis and visualization cluster. Those requests are due September 12. CISL accepts requests from university researchers for large-scale allocations every six months.

At the fall 2023 CISL HPC Allocations Panel (CHAP) meeting, CISL will allocate up to 440 million core-hours and 425,000 GPU-hours on the Derecho system and up to 3 petabytes of Campaign Storage space. Allocation requests should be submitted via the Allocations section of the ARC portal: https://arc.ucar.edu/.

Researchers are encouraged to review the proposal preparation instructions before preparing their allocation requests: https://ncar.pub/CHAP-university-instructions. The instructions include guidance on estimating Derecho core-hour and GPU-hour amounts prior to that system becoming generally available.

Because Cheyenne will be decommissioned in December, the CHAP will not be considering any requests for Cheyenne allocations. A limited amount of core-hours may be available for existing Cheyenne projects trying to complete work on that system; such projects should submit a supplement request, which will be considered on a case-by-case basis.

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 CHAP continues to closely scrutinize data management plans and storage requests, especially when proposals request a substantial portion of the storage capacity available to allocate.
