概要介绍了网格计算的基本原理和研究背景,以及网格计算的特点、应用和目前的研究现状。着重提出了一种应用于光学设计的网格计算系统,对这个系统的任务调度、通信方式以及整个作业的具体实施过程展开讨论。并且构建了一种网格仿真实验,用来测试本系统的运行情况,重点检测网格系统对整个作业执行的时间跨度长短和负载均衡性的好坏。仿真实验的结果表明,本网格计算系统对作业执行的时间跨度随着节点的增加成倍减小,在均衡负载等方面也有显著的效果,运行状况良好。
This paper introduces the basic principle and research background of grid computing, as well as the characteristics, application and current research status of grid computing. A grid computing system which is applied to optical design is emphatically put forward, and the task scheduling, communication mode and whole implementation of this system are discussed. And a grid simulation experiment is constructed to test the operation of the system and to focus on the time span and load balance of grid system for the whole job. The simulation results show that the time span of job execution in this grid computing system decreases exponentially with the increase of nodes, and it also has a significant effect on the load balancing and so on. The running status is good.
