| 摘 要： | 以"服务"的形式包装网格资源已成为一种趋势,并得到网格界的一致认可.为了更加充分灵活的利用网格资源,提出了一个网格虚拟服务动态部署架构以及基于此架构的服务平衡调度算法,通过服务按需部署和实时监控,动态调整资源在不同任务间的分配,并在需要时进行任务迁移,保证应用的服务质量.实验结果表明此系统较其它系统在资源利用率、QoS命中率上都有一定的提高.

| Abstract: | It has been become a trend that a grid resource is regarded as a service provided for the users. To make full use of the grid re- sources, a configuration of the virtual service dynamic deployment is proposed and the service balancing algorithm based on it is presented. By the way of the dynamic deployment and the monitoring of services, the allocation proportion of resources is adjusted between tasks and the task migration is done when needed to ensure the QoS of the applications. The experiments show that the system surpasses the other systems in the utilization of resources and the hit ratio of QoS. |
