【摘要】 网格计算研究的基本目的是实现最大范围内的计算资源共享,并提供协同计算能力;网格是把广域网上大量分布、异构资源进行整合,实现统一视图和统一访问接口的基础设施。资源信息服务在网格中具有重要地位,其作用是感知和监控异构资源,并为上层应用提供资源信息,从而为资源调度和选择系统策略提供依据。本文在深入研究网格监控相关技术的基础上,提出了基于多Agent的网格监控系统模型,并设计了一种基于多Agent的网格监控系统原型。该系统根据网格应用系统的一般特点采用层次架构,其基本架构遵循全球网格论坛提出的网格监控架构GMA。在系统的研究中引入了多Agent系统中多个Agent间的协作技术,解决了网格资源的动态性、可扩展性和异构性。在此系统的监控服务设计中,运用目前网格研究中的体系架构规范——Web服务资源架构(WSRF)构建网格监控服务,从而为与其他网格监控系统的互操作提供了统一的访问接口。实验结果表明:基于多Agent的网格监控系统能够有效地收集监控数据并为用户提供实时的网格监控服务,其功能和性能均达到了设计要求。更多还原

【Abstract】 As an up-to-date realm of computer science research, grid computing technology focuses on sharing of resources and cooperating of computing. The Grid is a basic information infrastructure which integrates a mass of heterogeneous resources distributed in wide area network, and constitutes a virtual organization with uniform interface and user view. The resource information service, perceiving and monitoring the heterogeneous resources, plays a key role in Grid technology. The resource scheduler and the system strategy selecting should work according to the resource information provided by the service.Based on studying grid monitoring technologies in depth, the grid monitoring system model based on multi-agent is proposed, and a new grid monitoring system prototype based on multi-agent is designed. It adopts hierarchical architecture according to usual grid architectures. Its basic architecture is accordance with Grid Monitoring Architecture (GMA), which is proposed by Global Grid Forum. In the research of system, collaboration technologies in multi-agent systems are used to solve dynamic, expand and heterogeneousness of grid resources. In the design of system monitoring service, Web Service Resource Framework (WSRF) is used to create a universal interface to facilitate the cooperation of different grid monitoring systems.The experiment results show that system can collect monitor data of grid resource and provide users grid monitor service more efficiently and easily, its functions and performance all meet the design requirements.更多还原
