【摘要】 网格是一种新兴的基础设施,网格计算在实现资源、计算和服务的共享等方面有着明显的优势,因此在很多方而都得到了广泛的应用.目前网格主要有3种结构:五层沙漏结构、开放式网格服务体系结构、网络服务资源框架,3种结构各有其产生和应用的背景,其演变过程表明了网格计算面向服务发展的方向,目前网格计算的研究工作主要集中在异构问题、可扩展性问题、自适应性问题、安全性问题、通信服务问题、服务信息服务问题等方面的研究.更多还原

【Abstract】 Grid computing is a new kind of infrastructure.Due to its apparent advantages in realizing the share of resource,Computing and service,Grid computing is widely applied in many aspects.At present GRID includes three architectures.They are the Five Layers Hourglass Model,the Open Grid Services Architecture and the WS-Resource Framework respectively.Those architectures have their respective background of their coming and application.The evolvement of these architectures reveals the service-oriented tendency of Grid computing.The current research of Grid Computing mostly includes the research of heterogeneity,scalability,adaptability,security,communication services,information services,etc.更多还原
