    2. DOE Mission Elements Energy Nuclear power, clean coal, fusion reactors, enhanced oil recovery, bio-fuels, reliability & security of electric power grid, new engine designs Environment Carbon sequestration, nuclear waste storage, environmental cleanup, climate research National Security Nuclear stockpile stewardship 07/11/2008 SIAM Annual Meeting 2008 DLB-2 2

    3. What kinds of questions can CS&E help answer for DOE? Can we predict the operating characteristics of a clean coal power plant? • How stable is the plasma containment in a Tokamak? • How quickly is climate change occurring and what are the uncertainties in the predicted time scales? • How quickly can the US recover if part of the power grid became inoperable? • How can new materials be designed with a specified desirable set of properties? Answering these and other important questions involves study ofincreasingly complex physical and engineered systems 07/11/2008 Applied Math at the DOE David L. Brown 3

    4. Office of Advanced Scientific Computing Research (ASCR) Mission: Discover, develop, and deploy the computational and networking tools that enable researchers in the scientific disciplines to analyze, model, simulate, and predict complex phenomena important to theDepartment of Energy. 4

    5. It’s not all about hardware … CS&E advances are essential for the exponential performance increases that drive scientific discovery through computation Combustion modeling Modeling advances Algorithm advances Hardware advances Excerpt from: A Science-Based Case For Large Scale Simulation Volume 2 http://www.pnl.gov/scales/docs/SCaLeS_Report_Vol2.pdf 5

    6. Applied Mathematics Research Program Research on mathematical models, methods and algorithms to enable scientists to accurately understand complex physical, chemical, biological and engineered systems. • Currently supported research activities (~ 100 projects): • Advanced linear algebra • Discretization and meshing • Multiscale, multiphysics systems • UQ and error analysis • Optimization • Other research • Fellowships & workshops • Outreach to mathematics, computer science and computational science community von Neumann 1903-1957 6

    7. Applied Mathematics Research New Research Thrusts • Multiscale Mathematics & Optimization for Complex Systems • http://www.sc.doe.gov/ascr/Research/AM/ComplexSystemsWorkshopReport.pdf • http://www.sc.doe.gov/ascr/Research/AM/MultiscaleMathWorkshop1.pdf • http://www.sc.doe.gov/ascr/Research/AM/MultiscaleMathWorkshop2.pdf • http://www.sc.doe.gov/ascr/Research/AM/MultiscaleMathWorkshop3.pdf • Mathematics for Analysis of Petascale Data • http://www.science.doe.gov/ascr/ProgramDocuments/Docs/PetascaleDataWorkshopReport.pdf • Joint Mathematics / Computer Science Institute(s) • http://www.csm.ornl.gov/workshops/institutes/ • Mathematics of Cybersecurity • http://www.science.doe.gov/ascr/ProgramDocuments/Docs/CyberSecurityScienceDec2008.pdf • http://csmr.ca.sandia.gov/~tgkolda/pubs/bibtgkfiles/SAND2009-0805-eco%20Math%20for%20Cyber.pdf • Unsolicited proposals: • http://www.science.doe.gov/grants/FAPN09-01.html 7

    8. CS&E Community Involvement • Learn more about ASCR programs • Be a reviewer • Panel reviews • “Postal” reviews • Participate in DOE workshops • ASCR-sponsored • Basic Energy Sciences (BES), Biological and Environmental Research (BER), Electricity Delivery and Energy Reliability (OE), Energy Efficiency and Renewable Energy (EERE), Nuclear Energy (NE) • Identify future research needs • Generate “strong” community interest • ACCOMPLISHMENTS! 8

    9. New “Breakthroughs” report • Each of Mathematics, Computer Science, and Applications will have a “breakthroughs” report to support FY11 DOE budget request • Each report will look back about eight years – the SciDAC era • What are the ten most important mathematical breakthroughs to computational science? • Not necessarily scaling issues, could be “more science per flop/byte stored/byte transmitted” • Please send your suggestions to david.keyes@columbia.edu 9
