一种基于蚁群算法的网格任务调度方法

网格资源具有动态变化,广域分布及系统异构的特性,如何分配调度这些资源成为网格计算研究领域一个重要研究课题。国内外在网格任务调度研究上已经做了大量工作,但是这些算法大多是基于计算网格的,不能很好的适应服务网格环境下存在任务相关性的调度,同时在适应网格的动态性、异构性上也存在不足。针对目前网格调度机制存在的问题,提出了一种基于蚁群算法的服务网格任务动态调度方法,仿真实验结果表明该算法具有较好的性能和自适应性。

A Grid Computing Task Scheduling Algorithm Based on Ant Algorithm

Grid resources have some features of dynamic change,geographical dispersion and heterogeneous systems,The task scheduling is a very important research issue for application basis in the field of grid computing.A lot of work have done on it,however these algorithms are mostly based on the computational grid.they aren't able to solve complex-task scheduling in the service grid environment and they are also inadequate in the dynamic and heterogeneous.A grid computing task scheduling algorithm based on ant algorithm is proposed,and the result of simulation proves it has better performance and flexibility.
