摘要
针对层次化网格模型结构,运用统计思想提出了一种新的资源分配与任务调度算法,不仅能够提高资源的利用率和系统的吞吐率,而且能够实现网格系统内部的负载平衡。算法主要包含三个功能模块,即负载跟踪模块、作业分配模块和负载监视模块。在解释了方案中各功能部件的作用及其相互之间关系的基础上,给出了相应的算法伪码。仿真实验表明,该算法是有效的。
Aiming at the hierarchical grid model structure,following statistical thinking,this paper proposed a new resource allocation and task scheduling algorithm,which could not only increase the utilization of resources and system throughput,but also realize the load balancing within grid systems.This algorithm consisted of three main modules which were load tracking module,job distributing module and load monitoring module.On the basis of having explained the functions of the different functional parts and the r...
