CHAP: May 2009 University Allocations Summary

The CISL HPC Advisory Panel (CHAP) met on May 14, 2009, 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 25 requests from university researchers whose research met the criteria listed above. All of the requests except for one received an allocation. The panel requested more information from the PI before making a recommendation, so the GAUs allocated by the May 2009 panel may increase.

University researchers requested 5.5 million GAUs (General Allocation Units). Requests ranged from a high of 900,000 GAUs to a low of 15,000 GAUs. The median request size was 180,000 GAUs.

A little over 4 million GAUs were allocated by the CHAP with allocations ranging from over 700,000 GAUs to 15,000 GAUs. The median allocation was 111,000 GAUs. 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 May 2009 panel meeting, 115 small allocations were made for a total of about 580,00 GAUs. One allocation of 47,000 GAUs (previously reviewed by the panel) was also made. So the total of university allocations for the past 6 months (including the May panel meeting) is 4.8M GAUs.

The CHAP was pleased with the large requests from the university community responding to the availability of IBM POWER6, bluefire, at NCAR. For more information on bluefire and its use see: http://www.cisl.ucar.edu/computers/bluefire/.
