【摘要】 网格计算是继Internet和Web技术之后,信息技术的第3次革命,最终将改变分布式资源的共享和服务方式。对网格计算进行了简单介绍,重点介绍网格系统构建的核心技术,即网格体系结构的研究及最新进展情况。且着重介绍了以协议为中心的5层沙漏结构和以服务为中心的新一代网格体系结构OGSA。更多还原

【Abstract】 Grid Computing is the third revolution of information technology after internet and web.It will change the mode of sharing distributed resource and services finally.A survey of grid computingwas given firstly.Then thenew research advanced in gridarchitecture was introduced,which is core technology in the design of grid system.Two grid architectures were emphasized on.One is five level hourglass model architecture which is focused on protocol,the other is OGSA(open grid services architecture) which is centered on services.更多还原
