CHAP: April 2010 University Allocations Summary

The CISL HPC Advisory Panel (CHAP) met on April 29, 2010, to review and recommend allocations for computational requests from university researchers with an NSF award 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 44 requests from university researchers requesting large allocations—the second largest number of requests received in the past 10 years. Forty requests received an allocation.

University researchers requested 17.8M GAUs (General Allocation Units). Requests ranged from a high of 3.6M GAUs to a low of 17k GAUs. The median request size was 260k GAUs.

A little over 6.2M GAUs were allocated by the CHAP with allocations ranging from 660k GAUs to 17k GAUs. The median allocation was 150k GAUs. Since requests were 307% of available resources the CHAP limited most allocations for multi-year projects to resources needed for the next year and looked more closely at the computational experiments being proposed. Four projects did not receive an allocation. Two of these projects will receive an allocation when their pending NSF proposals receive an award, while two other requests were not supported by the NSF.

The distribution of allocations is given in the chart below.

Not shown on the chart are the small requests and allocations for the university research community. During the six months preceding the April 2010 panel meeting, 107 small allocations were made for a total of about 461k GAUs.  One allocation of 77k GAUs (previously reviewed by the panel) was transferred to a new project.  So the total of university allocations for the past 6 months (including the April panel meeting) is 6.77M GAUs.
