  1. 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

  2. Presentation Topics • MICS • NERSC Center • Budgets • The Greenbook • Challenges/Opportunities

  3. 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.

  4. 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.

  5. National Energy Research Scientific Computing Center (NERSC) Advanced Computing Research Facilities Energy Sciences Network (ESnet) MICS is an INTEGRATED Program Research --> Users Disciplinary Science and Engineering BES,BER,FES,HEP,NP External to SC ASCR Underlying Technologies • Hardware • Software • Networking R&D forApplications ScientificComputing FundamentalResearch Testbeds • Applications, e.g. • Materials Sciences • Chemical Sciences • Combustion Modeling • Accelerator Science • High Energy Physics • Nuclear Physics • Fusion Energy • Global Climate • … • ... • Applied Mathematics • Advanced Computing Software Tools • Scientific Application Pilots • Computer Science • Enabling Technology Centers Groups of mathematicians, computer scientists, application scientists, and software engineers • Networking • Collaboratory Tools • Collaboratory Pilots • Access to Facilities • Link Researchers Facilities

  6. National Energy Research Scientific Computing Center -- Goal -- To provide state of the art, high performance computing capability resources and professional user friendly services to a broadly based user community of computational scientists in support of the missions of the Office of Science.

  7. NERSC-Enabled Research Accomplishments • Magnetic materials • Adaptive Mesh Refinement in Complex Geometries • Accelerator design • Stellerator optimization • Predicting Protein Structure • Microstructural Pattern Formation in Directional Solidification • Coupled Ocean/Atmosphere System

  8. Advancing Computational Science of Scale- Producing Real Results

  9. Budget History - NERSC, ACRF and ESnet at LBNL-

  10. 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.

  11. The Greenbook- Foundation of a Strategy

  12. 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.

  13. Personal Areas of Responsibility • Program Manager for NERSC, Acting • Program Manager for ACRFs, Acting • Program Manager for Scientific Applications Pilot Projects, Acting • Director, Technology Research Division • Laboratory Technology Research Program • SBIR and STTR Programs
