CHAP October 2020 Meeting

The CISL HPC Advisory Panel (CHAP) met October 8, 2020, in Boulder to review and recommend allocations for computational requests from university researchers with NSF awards in the atmospheric or closely related sciences. The CHAP's focus continues to be on the computational experiments being proposed and their efficiency, as well as on researchers’ justifications for data-storage requests.

The CHAP received 42 requests from 31 different universities and research institutions for more than 292 million core-hours on Cheyenne. The CHAP had slightly more than 200 million Cheyenne core-hours to allocate. Requests below 2 million core-hours were email-only reviews. The panel also reviewed storage requests for a total of 1.5 PB of Campaign Storage and 886 TB of project space. For awards, the panel targeted 2 PB of Campaign Storage and no project space due to high utilization of that resource. The panel also reviewed the biennial CESM Community request, which targeted 622.5 million core-hours spanning both Cheyenne and the forthcoming NWSC-3 system.

Following review, the panel recommended awarding 208 million core-hours on Cheyenne, 1.2 PB of Campaign Storage, and 0 TB of GLADE project space. The average award on Cheyenne was 4.9 million core-hours. Two requests were rejected based on concerns about how the additional core-hours would be used; both projects had millions of core-hours already available to them.
