CHAP: October 2011 Meeting

The CISL HPC Advisory Panel (CHAP) met on 6 October 2011 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 41 requests from university researchers requesting large allocations, reflecting a continued high level of interest in CISL resources; 40 requests received an allocation.

University researchers requested a total of 14.2M GAUs (General Allocation Units) for the final 8 months of Bluefire, which represented 3.5 times the resources available. Requests ranged from a high of 2.0M GAUs to a low of 30k GAUs. The median request size was 200k GAUs. For this early opportunity to request allocations on NWSC resources, a total of 27.2M GAUs were requested by 27 projects.

Approximately 4.1M GAUs were allocated on Bluefire by the CHAP to 35 projects, with allocations ranging from 300k GAUs to 33k GAUs. The median allocation was 80k GAUs. Because of the high Bluefire request levels, the CHAP considered computational plans carefully and instructed most projects to shift additional work to the much larger NWSC system. As a result, 30 projects received allocations totalling 16.6M GAUs on the NWSC system, ranging from 4.3M to 16k GAUs. Nine projects received allocations totalling 1.6M GAUs on the Janus Cluster.

The CHAP encourages all future university projects to consider the dramatic increase in available computing resources at NWSC in mid-2012 when preparing future allocation requests.

The distribution of the October 2011 allocations is given in the chart below.

CHAP Allocations bar chart

Not shown on the chart are the small requests and allocations for the university research community. During the six months preceding the October 2011 panel meeting, 86 small allocations were made for a total of about 1M GAUs. So the total of university allocations for the past 6 months is 5.1M GAUs.
