【摘要】 云计算是近年来计算机领域比较热点的一个研究方向,它将计算任务分布在大量计算机构成的资源池上,使各种应用系统能够根据需要获取计算力、存储空间和各种软件服务。随着云计算的发展和用户需求的不断增加,云基础服务设施也在不断的增加。如何对如此庞大的资源池进行管理与调度一直以来都是云计算研究过程中的关键问题,云计算的发展也是其资源管理与调度方法方面的发展更新。如此庞大的云基础服务设施也必定消耗了大量的能源,在倡导节能减排的今天,利用云资源进行计算的同时,也应该考虑计算时使用的能耗,如何降低计算时的能耗,提高效率,让云计算更加环保节能。本文分析了现有环境下进行云计算节能处理的可行性。对现有云计算中资源管理与调度构架进行分析,发现现有云计算利用虚拟化技术对资源进行调度时,需要重复对虚拟机进行启动与销毁,在此过程中有很多能量损耗,而在庞大的“云”资源中,这样的能量损耗又有很多。从而指出了在现有云计算调度技术的基础上,加入一个节能调度环节,在用户请求资源的时候,先进行节能预测,从而达到节能减排的目的。通过使用开源仿真平台CloudSim对该调度算法进行仿真,证明了算法的可行性和有效性,能够有效的降低云计算平台的能耗。更多还原

【Abstract】 Recently,Cloud Computing is a hotspot research area in the domain of computer. It will distribute computing tasks in a computer which the basins, all kinds of resources,enable application system to obtain calculation, storage space and software services. infrastructural services of cloud computing are the increase along with development and user demands. It is a key problem that how to manage and control such a large pool of resources. The development of Cloud Computing is its own resources management and the method of development.This article analyzes the current situation in the energy to the feasibility of the cloud computing, and analysis the existing computing resources management framework in the management the existing calculation of virtualization technology resources management, to be repeated for a virtual machine to start with destruction, in this process has a lot of energy consuming, but in large "clouds" resources, such losses and have a lot of energy, as pointed out in the existing calculation on the basis of the technology to join an energy efficient management, the user requests for resources, to save energy, energy conservation to achieve purpose of emissions reduction.By using open platform to the simulate cloudsim the algorithm for emulation is in order to prove the effectiveness and feasibility of the algorithm.It will effectively reduce calculation of the platform eventually.更多还原
