The application of petascale computing to these areas should enhance US economic competitiveness and our knowledge of the universe around us; 2 and such factors have motivated a small band of experts to address petascale computing issues through a series of workshops and conferences. Such activities engendered small-scale point design studies; which the National Science Foundation; DARPA; and NASA funded to look at different aspects of petascale computer design. Recently; these agencies funded a project to examine in more detail the so-called hybrid technology multithreaded (HTMT) computer as a pathway to petascale computing. This article discusses the current status of ef- forts to make petascale computing a reality; but first we review trends in supercomputer performance over the past 50 years;

摘要：

Although the challenges to achieving petascale computing within the next decade are daunting, several software and hardware technologies are emerging that could help us reach this goal. The authors review these technologies and consider new algorithms capable of exploiting a petascale computer's architecture.
