【 摘 要 】

This report describes efforts carried out during early 2008 to determine some of the science drivers for the 'NERSC-6' next-generation high-performance computing system acquisition. Although the starting point was existing Greenbooks from DOE and the NERSC User Group, the main contribution of this work is an analysis of the current NERSC computational workload combined with requirements information elicited from key users and other scientists about expected needs in the 2009-2011 timeframe. The NERSC workload is described in terms of science areas, computer codes supporting research within those areas, and description of key algorithms that comprise the codes. This work was carried out in large part to help select a small set of benchmark programs that accurately capture the science and algorithmic characteristics of the workload. The report concludes with a description of the codes selected and some preliminary performance data for them on several important systems.
