一种网格信息服务模拟器的研究与设计

A Survey and Design of a Grid Information Services Simulator

网格技术为广域范围内各种资源、应用以及服务的共享和聚合提供了有效手段,而网格系统的设计是一项非常复杂的系统工程。网格模拟器的出现,给网格研究带来了极大的便利。本文针对网格系统的信息服务部分,在对现有的典型系统进行分析的基础上,对其各部分功能进行抽象和划分,形成独立的功能部件,提出了一种对网格信息服务进行模拟研究的机制,为分析其在不同架构下的性能和可扩展性提供了有效手段。

In recent years, gird computing provides efficient methods of the share and aggregation for large numbers of resources, applications and services in wide area. But the design of grid system is a complex systems engineering. The emergence of the grid simulator brings the research a great amount of convenience. In this paper, we analyze existing typical grid information service systems, abstract and partition their function modules and form the independent mod- ules. Based the above results, we design the mechanism of simulating grid information services, and provide efficient methods for analyzing the performance and scalability under various architectures.
