  1. Update on the DOE SciDAC Program Vicky White, DOE/HENP Lattice QCD Collaboration Meeting Jefferson Lab, Feb 1 2002

  2. The SciDAC Program is alive and well • and needs you to … • Present some scientific results - “tied” to SciDAC • Demonstrate the benefits of working collaboratively (together and with the Computer Scientists) • Help make the case for increased funding for the next stage of the program, Hardware and Networking Infrastructure (Topical Computing centers in your terms) SciDAC Lattice All-Hands Meeting, Jlab

  3. SciDAC is an integrated program • Across all the program offices of the Office of Science • Focus on large collaborative efforts • Interdisciplinary teams • Science through computation • Assistant Head of Office of Science for SciDAC SciDAC Lattice All-Hands Meeting, Jlab

  4. Program Offices of the Office of Science • High Energy and Nuclear Physics (HENP) (Rosen) • Division of High Energy Physics (O’Fallon) • Division of Nuclear Physics (Kovar) • Basic Energy Sciences (BES) (Dehmer) • Combustion, Computational chemistry, Materials, Geo ….. • Biological and Environment Research (BER) (Patrinos) • Global Climate, Environment, Medical, Human genome…. • Fusion Energy Sciences (FES) (Davies) • Advanced Scientific Computing Research (ASCR) (Oliver) • Computer Science, Applied Math, Facilities & Networks, Collaborative tools SciDAC Lattice All-Hands Meeting, Jlab

  5. Office of Science (SC) • Acting Head of SC – Jim Decker • Very positive and supportive of SciDAC • Wants to put it on the top-10 list • Recent Previous SC heads • Mildred Dresselhaus • Martha Krebs • Acting SciDAC Head – Dave Bader (BER) • Recent Previous ScidDAC heads • Steve Eckstrand (FES) – acting • Thom Dunning --- the guy who got the program started SciDAC Lattice All-Hands Meeting, Jlab

  6. Looking forward to new leadership • Ray Orbach – nominated for Director of Office of Science • Awaiting confirmation • Person identified (Computer Science) to take on SciDAC (March/April?) SciDAC Lattice All-Hands Meeting, Jlab

  7. SciDAC Program Objective To make a step-function leap in our ability to use computation for scientific discovery in theexploration of thefundamental processes of nature. Theory Experiment Simulation and Computational Science 3-pronged integrated approach to scientific discovery SciDAC Lattice All-Hands Meeting, Jlab

  9. Budgets across Office of Science • In FY2000 request was for $60M growing rapidly to $120M/ year • FY2001 actual budget – total of $57.3M • ASCR $37.4 M (~ $3.15M -> HENP) • BES $ 1.9 M • BER $ 8.0 M • FES $ 3.0 M • HENP $ 6.9 M • FY2002 pretty much flat-flat SciDAC Lattice All-Hands Meeting, Jlab

  10. 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 Lattice All-Hands Meeting, Jlab

  11. High Energy and Nuclear Physics SciDAC Yearly Budgets • The HENP SciDAC projects • Science and Simulation of Particle Accelerators • $1.8M + $0.8M ASCR • Supernova Science (2 projects) • $1.25M/year + $0.4 M ASCR • $ 0.52M/year + $0.12M ASCR • Lattice Gauge Theory calculations • $1.85M/year + $0.13M ASCR • Particle Physics Data Grid (joint with ASCR) • $1.44 M + $1.7M ASCR SciDAC Lattice All-Hands Meeting, Jlab

  12. Basic Energy Sciences ($2M) Bunch (~ 11 ) of small awards Biological and Environmental ($8M) Climate (~15 sub-awards) Fusion ($3M) 5 projects (1 carry-over) ASCR ($37M) 6 Grids & Portals 5 Networking 7 Integrated Software Infrastructure Centers (ISIC) “Glue” money for integrating science projects with the ISIC and helping with other Computer Science holes Some hardware SciDAC Project Portfolio – other offices SciDAC Lattice All-Hands Meeting, Jlab

  13. Recent Principal Investigator (PI) meeting • Was to be a grand kickoff meeting in Sep. • 9/11 derailed that • Held Jan 16/17 in Washington DC area • Chance for • Support and interest of Jim Decker • Foster collaboration – use ISICs, cross fertilization SciDAC Lattice All-Hands Meeting, Jlab

  14. 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 Lattice All-Hands Meeting, Jlab

  15. 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 Lattice All-Hands Meeting, Jlab

  16. 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 Lattice All-Hands Meeting, Jlab

  17. 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 Lattice All-Hands Meeting, Jlab

  18. 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 Lattice All-Hands Meeting, Jlab

  19. Results from PI meeting • HENP Posters were a great success • HENP Presentations went down very well • Material from Mezzacappa presentation used by senior ASCR person in recent talk • Very good HENP visibility • Many mentions in others talks. Every ISIC effort strongly driven by an HENP application • Many connections to Computer Science efforts • Nice words from Ed Oliver SciDAC Lattice All-Hands Meeting, Jlab

  20. Budgets across Office of Science • In FY2000 request was for $60M growing rapidly to $120M/ year • FY2001 actual budget – total of $57.3M • ASCR $37.4 M (~ $3.15M -> HENP) • BES $ 1.9 M • BER $ 8.0 M • FES $ 3.0 M • HENP $ 6.9 M • FY2002 pretty much flat-flat SciDAC Lattice All-Hands Meeting, Jlab
