摘要
对资源进行有效的管理和调度可以提高网格系统的利用率.针对计算网格中的负载平衡问题,为减少网络通信量,提出一种分布式的网格作业调度模型,并给出了其相关算法:将轻负载节点逐个收集到一个队列,并设定一个可调节的刷新时间,当重负载节点提出调度请求时,直接从轻载节点队列中取一轻载节点并把负载转移到该节点上,从而解决了资源调度中的负载平衡问题.
Effective management and scheduling of resources can increase the utilization of grid system.For the issues of task-balancing in grid computing,in order to reduce the communication,a distributed scheduling pattern in grid is proposed,and the relevant algorithm is given.The algorithm collects each light load node to a queue,and sets an adjustable refresh time,when the heavy load nodes requests to schedule,the task will be transferred to the node which is taken out from the queue so as to solve the issues of task-balancing in grid.
