摘　　要：一简介 互联网络的普及和高速网络成本的大幅度降低,计算机计算能力的迅速增长,使得在改变传统计算方式的同时,也改变了人们对计算机的使用方式.将地理上分布的计算资源(包括数据库、贵重仪器等其它的各种资源)充分利用起来,协同解决复杂的大规模问题,这就是网格计算(GridComputin-g)[1-3.117].近几年来,网格计算已经逐渐成为超级计算发展的一个重要趋势,它可以解决仅靠本地资源无法解决的复杂问题.Some opinions and research results on grid computing are included in this paper. A simple introduction about grid computing and the related works are provided at first. The paper argues that the main problems to be resolved in grid computing are resource sharing, friendly interface, high performance computation and security. The features of grid computing are orientation to how to resolve challenging problems and how to employ all kinds of resources more easily, how to collaborate distribute and dynamic resources and how to deal with complex resource structure and multiple resource management. The paper presents a design of a prototype grid system and also describes the key technologies of the prototype grid system. The implemented function of the prototype system is briefly introduced and several typical applications based on the system are also given. Finally, a simple conclusion is given.
