1 HPC, the Department of Energy and the Obama Administration: A Strategic Perspective Victor Reis Senior Advisor Department of Energy October 9, 2009 Extreme Computing

2 Outline Strategic Planning (One Slide) –Vision, Assets, Strategy President Obama’s Vision DOE as a strategic asset The ASCI Strategy – An example Current DOE HPC Strategies Potential DOE HPC strategies & applications Summary

3 Strategic Planning Vision Assets Strategies

4 “We must harness the power of nuclear energy on behalf of our efforts to combat climate change, and to advance peace opportunity for all people.” President Obama Prague, April 5, 2009 “The United States will take concrete steps towards a world without nuclear weapons…. Make no mistake: As long as these weapons exist, the United States will maintain a safe, secure and effective arsenal to deter any adversary, and guarantee that defense to our allies.” Vision: Nuclear

5 And my budget doubles funding for the Department of Energy's Office of Science, which builds and operates accelerators, colliders, supercomputers, high-energy light sources, and facilities for making nano-materials -- because we know that a nation's potential for scientific discovery is defined by the tools that it makes available to its researchers. REMARKS BY THE PRESIDENT AT THE NATIONAL ACADEMY OF SCIENCES ANNUAL MEETING April 27, 2009 Vision: Science & DOE “We have been talking about energy for decades. But there is no longer a disagreement over whether our dependence on foreign oil is endangering our security. It is. There is no longer a debate about whether carbon pollution is placing our planet in jeopardy. It’s happening.” WEEKLY ADDRESS: President Obama Calls Energy Bill Passage Critical to Stronger American Economy June 27, 2009 Vision: Energy & Climate

6 “We know what needs to be done. We know that our planet's future depends on a global commitment to permanently reduce greenhouse gas pollution. We know that if we put the right rules and incentives in place, we will unleash the creative power of our best scientists, engineers, and entrepreneurs to build a better world.” “That so many of us are here today is a recognition that the threat from climate change is serious, it is urgent, and it is growing.” President Obama: Speech to the United Nations On Climate Change. 22 Sept 2009 Vision: Climate Change

7 Assets: DOE has done a lot in the last ~ 15 years: e.g.: Major New Science Installations –Spallation Neutron Source – Oak Ridge –Advanced Photon Source - Argonne –National Ignition Facility - Livermore –Linac Coherent Light Source - SLAC –Relativistic Heavy Ion Collider - Brookhaven –Microsystems and Engineering Sciences Application (MESA) – Sandia –Dual Axis Radiographic Hydrodynamic Test - Los Alamos Nuclear Weapons - Stockpile Stewardship –Much deeper understanding of nuclear explosive process 114 Annual Weapon Certifications without underground testing Simulation has driven High Performance Computing Leadership Stockpile Life Extension (W87, B61, W76) Non-Proliferation –Russian Weapons and Material Security much improved –International Safeguards, Global Threat Reduction Inititiative –“Megatons to Megawatts” (367 MTons of Russian HEU eliminated) Defense Clean Up –Rocky Flats –Fernald –Mound Radioactive Waste Disposition –Waste Isolation Pilot Plant (WIPP) 29 Nobel Prizes

14 What are the models (strategies) for HPC development? Science Model Applications Model Commercial Model DOE Science Model - DOE SciDAC – Scientific Discovery Through Advance Computing Broad, Open, Peer Reviewed, Balanced, Important Science Problems Best Buyable HPC’s HPC support tools – math, algorithm’s, software etc. Manage user computer cycles to priority problems Applications Model – DOE NNSA ASCI/ASC Focus on time urgent national problem “closed” community Develop new computers/software/environments Partnerships with HPC industry Targeted Investments in industry R&D Big Investment, “Tight” management Potential HPC Strategies

15 How “applications driven” will the next generation of HPC architectures be? What are the DOE HPC applications? Who cares? How much performance, when? Scale of the investment? Breadth of applications What is the level of DOE/Industry partnership? What is the model of DOE HPC program? From the Perspective of HPC Development: Commercial Spinoff?
