摘    要:为了达到更为经济的扩展集群的目的,本文从使用云计算扩展集群的角度出发,提出了一种集群扩展的基本构架;描述了两种策略,本地优先策略、云环境优先策略,并根据云计算的特点,提出了一种基于计算强度的新型调度策略。此外,设计了调度器系统,并在不同环境下对每种策略进行了分析比较,得出基于计算强度的调度策略的低成本和较多任务超时的特点。最后,对如何使用云计算扩展本地集群更为经济,进行了分析。

关 键 词:云计算  集群扩展  虚拟化  调度

Abstract:For economic expansion of cluster, a basic framework was pointed out based on the capability of cloud computing to increase the capacity of clusters. Two scheduling strategies, i.e., local priority strategy and cloud environmental priority strategy, were discussed and a new scheduling strategy based on calculation was proposed. Also, designed scheduler system indicated that the proposed scheduling strategy would require less cost but possess more overdue tasks other than the two strategies under several conditions. Finally, we conclude how to use cloud computing more economically to extend the local cluster.
Keywords:cloud computing  cluster expansion  virtualization  scheduling
