摘要 网格任务调度算法是影响网格成功与否的关键技术之一.本文首先描述了网格计算环境中的DAG任务调度模型.然后,结合网格计算环境的特点,讨论了多个相依性任务组成的应用任务调度问题,并对GS和CIGS算法进行了全面而深入的研究,并在此基础上提出了一个CIGS算法的改进算法. Algorithm research of task scheduling is one of the key techniques in grid computing. This paper firstly describes a DAG task scheduling model used in grid computing environment, secondly discusses generational scheduling (GS) and communication-inclusion generational scheduling (CIGS) algorithms. Finally, an improved CIGS algorithm is proposed to use in grid computing environment, and it has been proved effectively.
