面向21世纪的广域高性能元计算技术

Wide-Area High Performance Metacomputing for 21 Century

一、引言高性能并行与分布计算是关系到国家战略利益的核心高技术,也是国民经济发展的重要基础,是一个重大的基础研究问题。由于计算机微处理器的速度越来越高,网络通信技术的迅猛发展,网络规模的扩大和速度的提高,特别是Internet技术的兴起和广泛应用,网络已经交叉纵横整个世界。与此同时,人类的应用需求朝着高性能、多样性、多功能发展。

In order to solve the questions of scientific applications and commercial applications, many high-performance applications require the ability to exploit diverse, geographically distributed computing and data resources. These applications use high-speed networks to integrate supercomputers, large databases, archival storage devices, advanced visualization devices, and/or scientific instruments to form networked virtual supercomputers or metacomputers. The metacomputing, in fact, is trend of high performance parallel and distributed computing in the future.
