基于G1obus网格服务的作业调度的实现

为了实现作业调度系统的均衡分布,提高资源利用率和系统的吞吐率,通过对网格服务的研究,设计并实现了一种基于Globus网格服务的作业调度系统.提出了网格服务的模式,给出了作业调度系统的结构形式;设计并实现了一种综合考虑作业数、各结点性能以及当前负载情况的作业调度分配器系统.实验结果表明,此分配器系统能有效改善作业的分配和调度,大大提高分布式网络资源的利用率.

Implementation of dispatching job based on grid service of Globus

In order to achieve balanced distribution of job dispatcher system and to improve utilization ratio of resource and handling up rate of system, a job dispatcher system based on grid service of Globus was designed and implemented after researched grid service. Firstly, grid service model was presented and structure ofthe system was also put forward. Then thejob dispatcher system, whichcould consider syntheticaUy situations aboutjob count, performance ofeachjoin points and present load, was designed and implemented. Experiment shows that the system could improve the efficiency of dispatching job and the utilization ratio of distributed network resources.
