  1. High Energy and Nuclear Physics SciDAC Program Vicky White, DOE/HENP SciDAC PI Meeting, January 15, 2002

  2. High Energy and Nuclear Physics SciDAC Program Objective • To make a step-function leap in our ability to use computation for scientific discovery in the exploration of thefundamental processes of nature. • Theory • Experiment • Simulation and Computational Science 3-pronged integrated approach to scientific discovery SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White

  3. High Energy and Nuclear Physics SciDAC Program • The HENP SciDAC program consists of 5 projects • Science and Simulation of Particle Accelerators • complex and expensive tools used throughout DOE for scientific discovery • Supernova Science (2 projects) • to discover the fundamental mechanisms of these complex natural systems • Lattice Gauge Theory calculations • to test and explore the Standard Model (QCD) and to interpret NP and HEP experiment results • Particle Physics Data Grid (joint with ASCR) • Collaborative tools for large geographical dispersed researchers needing access to data and computing resources SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White

  4. Challenges for HENP SciDAC • Extend our traditions of huge international collaborations for experimental science into Theory and Computational Science • work in multi-disciplinary teams, build community codes to deal with the size and complexity of the problems • apply innovative math and computing techniques and algorithms to problems • work effectively together (Collaborative Tools/Grid) • Strive for science deliverables soon and harness all the human and computing resources to meet the science goals SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White

  5. Challenges for HENP SciDAC • Evolve the scientific codes to run on the multi-Teraflop computers of tomorrow • Portable, scalable codes that can use today’s resources for scientific discovery and be prepared for the next generation of computing resources • Well layered, structured and supported community-wide codes • Instrumented codes to optimize performance and understand the type of computers that will meet the needs in the most cost effective manner SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White

  6. Presentations from 2 of the HENP SciDAC projects • Both have gone a long way in forming true multi-disciplinary collaborations with strong ties to applied mathematicians and computer scientists • Both have scientific goals with some short-term results expected, that they will tell you about • Shedding New Light on Exploding Stars: Terascale Simulations of Neutrino-Driven Supernovae and their Nucleosynthesis (Mezzacappa – PI) • Advanced Computing for 21st Century Accelerator Science and Technology (Ryne, Ko – PIs) SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White

  7. SciDAC center for Supernova Research (Woosley – PI) • Funding for 2 labs and 2 universities • Good start on multi-disciplinary team • Many applied math and computing challenges • Synergy with other projects? Impact of a supernova on an adjacent star SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White

  8. National Computational Infrastructure for Lattice Gauge Theory (Sugar- PI) • Representing ~60 Theorists in the US. Funding to 3 labs and 6 universities • National effort to regain US competitiveness • put in place the software and hardware needed for accurate lattice QCD calculations SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White

  9. National Computational Infrastructure for Lattice Gauge Theory (Sugar- PI) • Huge strides made in collaborative approach • + starting to work with computer scientists on performance metrics and optimization of code • Accurate computations of important scientific constants requires tens of Tflop years • Need highly cost-effective Topical Computing Centers for Lattice QCD – aiming at below $1/Mflop and targeting two different machine architectures – (1) Custom built for QCD and (2) Commodity PC Clusters with low latency networking SciDAC PI Meeting, Reston, VA High Energy and Nuclear Physics, Vicky White
