CHAP: April 2019 Meeting

The CISL HPC Advisory Panel (CHAP) met April 4, 2019, 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.

There were 28 requests from 21 different universities and research institutions for just under 148 million core-hours on Cheyenne. On Cheyenne, the CHAP has 175 million core-hours to allocate at each meeting. Requests below 1.6 million core-hours were email-only reviews. At this meeting, the panel also continued to scrutinize storage requests, targeting 250 TB of project space and 1 PB of Campaign Storage. The low volume of requests may have been affected by delays in award processing at NSF due to the federal government shutdown earlier in the year.

The panel recommended allocations of 103 million core-hours on Cheyenne. The average award was 3.7 million core-hours. Two requests from the same PI were recommended for no award; in both cases, the reviewers believed that due to miscalculations in the costs of runs, all the work could be completed within the PI’s existing small allocations. 

Following review, 87 TB of GLADE project space and 1.1 PB of Campaign Storage were recommended; all HPSS requests were awarded as Campaign Storage. Detailed reviews are stored in the XRAS system; email notifications to recipients will include the anonymized reviews.
