【摘要】 网格是一种信息社会的网络基础设施,正处在不断发展和变化当中。简单地说,它将实现互联网上所有资源的互联互通,包括计算资源、存储资源、通信资源、软件资源、信息资源、知识资源等。网格将连通一个个信息和资源孤岛,让人们的工作和生活变得更方便。本文首先介绍了网格基础,并对三种网格体系结构的原理、技术规范、以及发展作了详细阐述。网格体系结构是关于如何构建网格的技术,目前流行的有三个网格体系结构:五层沙漏结构、开放网格服务体系结构、Web服务资源框架。结合体系机构原理,深入研究了目前较为流行的网格工具包Globus Toolkit4(GT4)中的多个组件:网格安全基础设施(GSI)、监测与发现服务(MDS)、网格资源分配管理(GRAM)。通过对Globus各组件角色及原理的描述,结合武汉华冠信息技术有限公司创新基金项目(SOGCP)提出了企业网格概念,给出了企业网格的构架平台。网格技术的资源共享特征可以解决企业内部大型计算和集成问题,同时GSI提供的单点登陆等功能也能解决安全性问题。最后设计并实现了企业信息化平台上网格资源、服务开发和监测。基于GT4这一开放工具包,遵循网格体系框架WSRF原理,分别按照三种模式:同时实现服务与资源、单独定义资源、多个资源,开发了虚拟组织下的三种方式的网格服务,对服务的实现机理、实现方法进行了全面阐述。并使用GT4中的MDS与ganglia作接口,监控和发现网格环境中的资源和服务。更多还原

【Abstract】 Grid is an infrastructure of the information society, which is constantly developing and changing. Simply, it realizes that all the resources, including computin, storage, communication, software, information, knowledge and so on, to achieve the interoperability of the Internet. Grid connects all the single information and resource so that people can work and make life more convenient.This paper described the Grid structure, technical specifications, and development of the three architectures.Grid Architecture is about how to build a technology of grid. There are three popular grid architectures, the Five-Level Sandglass Architecture, the Open Grid Services Architecture, the Web Services Resource Framework. Thoroughly studied the components of the Globus Toolkit4 (GT4), which is epidemic: Grid Security Infrastructure (GSI), Monitoring and Detection Services (MDS), the Grid Resource Allocation Management (GRAM). After the research of the components.Based on the Innovation Fund project (SOGCP) in China Champion Information Technology Co., Ltd., proposed the concept of the enterprise grid whose platform was given next. The resource communion can solve the integration problems and GSI can support security architechture.At last, designed and implemented how to develop and monitor the resources and services in the enterprise inormation platform based on the open software GT4 and followed WSRF principle, developed the three respective models : services and resources achieved at the same time, the separate definition of resources, more resources. Comprihensively explanation the design and implementation of three grid services in the virtual organization. And then realized monitoring and discovering the resources and services grid by the MDS and ganglia adapter.更多还原
