信息技术前沿导论课程论文 浅谈网络计算与应用 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有哪些信誉好的足球投注网站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。网格计算技术；计算节点；超级计算机；超处理能力；资源管理Abstract: Grid computing is a new distributed technology, which connects distributed and heterogeneous resources with high-speed network integrating a super computer of processing capacity. The paper not only explain significance and architecture of grid computing, but also expand on several kernel technology such as OGSI, resource management,task management, task? scheduling , high rate communication, security, ect. Aiming at the particularity of the grid computing environments, 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 balance load. Task users summit may be executed in relatively tight resource sets, which will not only decrease the total communication 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.
