CHAP: October 2018 Meeting

The CISL HPC Advisory Panel (CHAP) met October 11, 2018, 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 awarded 131 million Cheyenne core-hours at the meeting and also carefully reviewed storage requests to ensure that projects made efficient and appropriate use of CISL’s storage resources. All university HPSS awards are being made for CISL’s new Campaign Storage system. We expect the new system will prove much more convenient for university projects. Similarly, analysis allocations are being awarded on the new Casper system since Geyser and Caldera will be retired in December 2018.

There were 34 requests from 31 different universities and research institutions for just over 354 million Cheyenne core-hours; 213 million of the total was from one request. The CHAP has 175 million Cheyenne core-hours to allocate at each meeting. Requests below 2 million core-hours were email-only reviews. The panel also reviewed the two-year plan for the CESM Community allocation of 460 million core-hours.

The panel recommended allocation of 131 million Cheyenne core-hours; the average award was 3.8 million core-hours. Following review, 200 TB of GLADE project space and 1 PB of Campaign Storage were recommended.

Detailed reviews are stored in the XRAS system; email notifications to recipients will include the anonymized reviews. One request was rejected based on the reviewer’s assessment that the runs proposed would not address the science objectives described.
