U. S. Department of Energy Current Facilities Portfolio Office of Science Advanced Scientific Computing Research Program • High Performance Production Computing Facility (NERSC) – Delivers high-end capacity computing to entire DOE SC research community – Large number of projects (200 – 300) – Medium- to very-large-scale projects that occasionally need a very high capability – Annual allocations • Leadership Computing Facilities – Delivers highest computational capability – Small number of projects (10 – 20) – Multiple year allocations June 12, 2006 NERSC Users Group Meeting 4

U. S. Department of Energy ASCAC Facilities Report April 2004 Office of Science Advanced Scientific Computing Research Program Regarding ASCR High Performance Facilities: • Conclusions – Current Office of Science high-end computer and networking facilities are among the best in the world – Current and expected near-term Office of Science high-end computing resources are far from adequate to meet the anticipated needs of its science and engineering missions and associated scientific communities. • Recommendations – Investment decisions in high-end computing should be guided by the science drivers – Over a three-year time frame, substantial investments are required to begin to return the United States to leadership in high -end computing. – The Office of Science should manage its advanced computing resources as a single, coordinated facility June 12, 2006 NERSC Users Group Meeting 5

U. S. Department of Energy American Competitiveness Initiative Office of Science Advanced Scientific Computing Research Program In the President’s State of the Union Address on January 31, 2006, President Bush stated, “I propose to double the federal commitment to the most critical basic research program in the physical sciences over the next ten years. This funding will support the work of America’s most creative minds as they explore promising areas such as nanotechnology, supercomputing, and alternative energy sources. ” Secretary Bodman, Ibid “Developing revolutionary, science-driven technology is at the heart of the Department of Energy’s mission. To ensure that America remains at the forefront in an increasingly competitive world, our Department is pursuing transformational new technologies in the cutting-edge scientific fields of the 21 st century—areas like nanotechnology, material science, biotechnology, and high-speed computing. ” June 12, 2006 NERSC Users Group Meeting 6
