摘　　要：提出了一种基于Globus的网格计算模型实现框架,以提供符合OGSA标准的通用、方便、高效、安全的网格计算平台.在该平台下,提供了网格资源管理和访问的安全性,通过调用Globus中的API函数库和MPICH-G2平台,可解决分布式异构环境下的大规模协同计算问题.同时,为用户可交互式的和安全的访问网格资源提供了透明的、与资源物理位置无关的、统一的服务接口,增强了系统的可用性和可扩展性.Computational grid is intended to organize efficiently geographically distributed computational resources to complete high performance computation tasks. Unfortunately, it is difficult to construct an actual and usable computational Grid platform because it is complicated in the grid computational environment. Authors construct an implementation framework of computational grid based on globus toolkits software components. The framework provides a general, convenient, efficient and secure grid computation platform and conforms to OGSA standard. Authors discuss the components of the framework and its operational principle. It can solve the problem of large-scale coordinated computation in the distributed and heterogeneous environment by calling Globus API and MPICH-G2 platform. Finally, provide a uniform service interface for users and improved usability and scalability for the system.
