The NERSC Center--From A DOE Program Manager’s Perspective-- A Presentation to the NERSC Users Group Walter M. Polansky Acting Program Manager for NERSC LBNL February 22, 2001
Presentation Topics • MICS • NERSC Center • Budgets • The Greenbook • Challenges/Opportunities
Need for Information Technology R&D • Vendors cannot meet requirements for high-performance computing because DOE science programs • require computing capabilities 10 to 100 times greater than typically available in commercial systems. • move hundreds to thousands of gigabytes of data between only a few locations.
High Performance Computers and Networks-- Importance to DOE Science -- • Many scientific questions important to DOE involve the integration of many scientific disciplines with characteristic lengths and times that range over many orders of magnitude (e.g. combustion). • Computer simulation is the only practical way to study some systems (e.g. fusion plasma, climate, genome). • Computer simulation can complement data and provide insight into the behavior of systems. • High performance networks are critical to harness distributed resources for the analysis of experimental data (millions of gigabytes/year) and to support distributed simulations.

Thoughts on the Greenbook • Greenbook objective- Make a compelling case, based on the science, for upgrading NERSC resources (hardware + services). • Quality of science enabled by current NERSC. • Existing and planned research opportunities unmet with present resources. • Target Audience- Office of Science program managers. • Other interested parties- OMB, OSTP, Congress, IG and GAO. • Attributes- • Cognizance of plans and initiatives (e.g. Flagship-Topical Center concept, nanotechnology, SciDAC). • Good scientific and technical content; but readable by non- scientists. • An Executive Summary that (1) provides a concise overview of the document; (2) and coaxes the reader to continue.
Challenges/Opportunities • Increase awareness of NERSC-enabled contributions to the Office of Science mission. • Remain engaged in NERSC planning and operations. • Share information and experiences with user groups at other computing centers. • Identify recent major scientific accomplishments and researcher recognition directly influenced by NERSC. • View NERSC as an SC resource and asset.
