摘要：作为一种新型的分布计算技术,网格计算将地理上分布的、异构的资源 用高速网络连接在一起，集成一台高速的超级计算机。分析了网格计算的意义、 体系结构、资源管理、任务管理与任务调度、高速通信和安全等核心技术，以及 网格应用实例和OGSI,并在资源管理方面提出了一种类似于搜索引擎技术组织 局部资源，各局部资源管理系统通过P2P结构互连,实现任务迁移，达到负载平衡, 并保证用户提交的任务在一?组密集的资源集合上运行。网格计算的沙漏结构体 系，以及网格Z间存在的问题。并在此基础上全面剖析了 OGSA网格技术标 准。围绕OGSA的中心思想、结构和平台组成展开讨论。并设计了企业应用网 格计算的整合关键部分：发布和发现。

Abstract: Grid computing is a new distributed technology, which connects distributed and heterogeneons resources with high-speed network integrating a super computer of processing capacity? The paper not only explain significanee and architecture of grid computing, but also expand on several kernel technology such as OGS1, resource management, task management, task scheduling , high rate communication, security, ect. Aiming at the particularity of the grid computing environmerits, We designed a mechanism similar to technology of search engine with which we may registry, discovery, locate resources in Grid. The whole model of resource management is built by connecting task manager in local resource management system and others with P2P model. Task may migrate among task managers in order to balanee load? Task users summit may be executed in relatively tight resource sets, which will not only decrease the total comm uni cation overheads of the whole task but also enhance the performance of system? Then , we analyze the new Standardof the Grid: OGSA. In the endof thisarticle 、 we design the keypartsof Grid computing in enterprises application: thefunctionof dispatch and thefindfor the Grid service.
