CHAP: October 2012 Meeting

The CISL HPC Advisory Panel (CHAP) met October 18, 2012, at the NCAR-Wyoming Supercomputing Center (NWSC) 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.

There were 22 requests from university researchers requesting large allocations; 21 requests received allocations. The requests showed that the university community was prepared to make full use of the petascale Yellowstone resource. Requests totaled 65.8 million core-hours on Yellowstone, which represented 1.6 times the resources available. Requests ranged from a high of 13 million core-hours to a low of 270,000 core-hours. The median request size was 2 million core-hours.

The CHAP allocated approximately 31 million Yellowstone core-hours, with allocations ranging from 270,000 to 4 million core-hours. The median allocation was 1 million core-hours. With Yellowstone soon to be generally available, university users should request small allocations to conduct benchmark runs to provide more accurate calculations of their resource needs.

The CHAP encourages all future university projects to consider the dramatic increase in available computing resources made possible with Yellowstone when preparing future allocation requests, but also to give due consideration to large-scale storage needs and plans.

The distribution of the October 2012 allocations is shown in the chart below.
