云环境下能耗感知的公平性提升资源调度策略

Energy-aware fairness enhanced resource scheduling method in cloud environment

针对云计算环境下大量的能源消耗和一些用户非法占有计算资源的问题,为了节约资源,同时提高系统的公平性,使所有用户能合理地使用数据中心的所有资源,提出一种基于能耗感知的节能公平的资源调度算法(FGRSA)。该算法能高效调度各种类型的资源使所有资源使用量达到一个相对的公平。通过CloudSim仿真平台,对提出的调度策略进行仿真实验。实验结果表明,与Greedy算法和Round Robin算法相比,FGRSA能够在大幅度降低系统能耗的同时,保证各类型资源的公平使用。

To address the problems of large energy consumption and illegal possession of computing resources by users in cloud environment, a new algorithm named Fair and Green Resource Scheduling Algorithm （FGRSA） was proposed to save resources and enhance the fairness of the system, so that all users can reasonably use all the resources in the data center. By using the proposed method, various types of resources can be can scheduled to make use of all resources to achieve relative fairness. The simulation experiments of the proposed scheduling strategy was conducted on CloudSim. Experimental resutls show that, compared with Greedy algorithm and Round Robin algorithm, FGRSA can significantly reduce the energy consumption and simultaneously ensure fair use of all types of resources.
