摘要
针对云计算数据中心的能耗问题,提出了绿色云计算体系理论,设计了绿色云系统架构;基于该架构,将能量作为一种系统资源进行分配,提出了三种绿色任务调度算法分别是STF-OS、LTF-OS和RT-OS算法;对三种绿色任务调度算法可行性做了相关的理论分析,三种算法可以有效地减少能源消耗;通过扩展云计算仿真平台CloudSim实现了模拟实验,结果表明STF-OS算法降低数据中心能耗的能力最优。
For the problem of energy consumption in Cloud Computing data centers, this paper puts forward the theory of Green Cloud Computing and designs a green cloud system architecture. Based on the green cloud system architecture, the energy is considered as system resources to achieve resource allocation. Three green task scheduling algorithms are proposed and respectively named as the STF-OS, LTF-OS and RT-OS algorithm. The feasibility analysis of three algorithms is made with the relevant theory and shows that three algorithms can effectively reduce energy consumption. The simulation is set on the CloudSim by extending Cloud Computing platform. The results show that the STF-OS algorithm has the most optimal ability of the reducing energy consumption of data center.
