摘要： 空间信息网格是利用网格技术实现空间信息资源的共享、管理和提供空间信息服务的系统和各种的空间信息服务的基础设施,任务调度是分布式系统和网格系统最具有挑战的问题之一,Java语言里的多线程机制很好地解决了这一问题。该文主要研究了SIG中的任务调度技术,通过实验确定分布式系统里的线程数目,使系统性能获得局部最优。

Abstract: Spatial information grid is a system using the grid technologies to achieve the sharing,management of spatial information resources and to provide spatial information services and all forms of basic establishment about spatial information services.Task scheduling is one of the most challenging problems in the distributed system and grid system,which can be solved finely by Java multithread mechanism.This paper mainly researches task scheduling in spatial information grid.Through experiment,it configures the number of thread in the distributed system,which optimizes system performance partly.
