网格任务调度策略研究

Research on Grid Task Scheduling Algorithms

网格作为下一代Internet,具有动态性和异构性,如何有效的调度任务是影响网格成功与否的关键技术之一。首先总结了网格计算系统的体系结构和特征,分析了网格任务调度算法的基本原理和性能指标,并对各种调度策略和算法进行了分类和比较,从而为网格任务调度的研究提供了很好的参考价值。

As the third generation of the Internet, Grid has the characteristics of dynamics and heterogeneous property. How to solve the problem of task scheduling is critical for the success of the grid. In this paper we conclude the architecture and character of Grid, analyze the fundamental theory and performance metrics for the grid task scheduling algorithms, and classify common task scheduhng strategies. This paper has good values for the grid task scheduling research.
