The Future of Supercomputing
- Share to:
High-performance computing is important in solving many kinds of complex problems in domains from weather science and biology to national security. U.S. government spending on supercomputing has been relatively flat over the last 10 years and has declined compared to industrial or commercial purchases of high-performance systems.1 Some observers associate the trends with the end of the Cold War, during which both national security and scientific research needs were believed to justify spending on a range of high-performance computing programs. Others point to the influence of the changing marketplace for computing systems overall, which has seen an increase in demand for less expensive systems of less than maximal performance. Several factors have led to the recent interest in reexamining the rationale for federal investment in research and development in support of high-performance computing, including (1) continuing changes in various component technologies and their markets, (2) the evolution of the computing market (and particularly the high-end supercomputing segment), (3) experience with several systems using the clustered processor architecture, and (4) the evolution of the problems, many of them mission-driven, for which supercomputers are used.
