Supercomputers can advance knowledge and generate insight that would not otherwise be possible or that could not be captured in time to be actionable. Supercomputer simulations can augment or replace experimentation in cases where experiments are hazardous, expensive, or even impossible to perform or to instrument; they can even enable virtual experiments with imaginary worlds to test theories beyond the range of observable parameters.

Computer Science and Telecommunications Board convened the Committee on the Future of Supercomputing to conduct a 2year study to assess the state of supercomputing in the United States. Specifically, the committee was charged to do the following: · Examine the characteristics of relevant systems and architecture research in government, industry, and academia and the characteristics of the relevant market.

7 was that the Advanced Scientific Computing Centers funded by NSF had enabled important research in computational science and engineering and had also changed the way that computational science and engineering contribute to advances in fundamental research across many areas. The recommendation of the task force was to continue to maintain a strong Advanced Scientific Computing Centers program.

program. The resulting report, High Performance Computing for the National Security Community,14 released in the spring of 2003 and known as the IHEC Report, recommends an applied research program to focus on developing the fundamental concepts in high-end computing and creating a pipeline of new ideas and graduate-level expertise for employment in industry and the national security community.

a classified study by the JASONs to identify the distinct requirements of the Stockpile Stewardship Program and its relation to the ASC acquisition strategy. Roy Schwitters, the study leader, said that the report, released in 2003, concluded that "distinct technical requirements place valid computing demands on ASC that exceed present and planned computing capacity and capability."15 The 2003 Scales report, A Science-Based Case for Large-Scale Simulation,16 presents a science-based case for balanced investment in numerous areas -- such as algorithms, software, innovative architecture, and people-to ensure that the United States benefits from advances enabled by computational simulations.

It also calls for the Director of the Office of Science and Technology Policy to develop and maintain a roadmap for high-performance computing. ABOUT THE INTERIM REPORT An interim report was presented in July 2003, approximately 6 months after the start of the study.22 The report provides a preliminary outline of the state of U.S.
