计算机系统能耗模型的研究

With the rapid development of information industry, communication networks and devices consume a lot of energy, energy conservation is become more and more important, and many energy saving strategies have been proposed. However, the evaluation of the effectiveness of the energy strategy and monitoring equipment need to quantitatively understand the power consumption of systems. Using measurement devices can quickly and accurately get the power consumption of the system. But this approach is not financially feasible, especially in large server farms etc. One of the feasible methods is to model the system's power consumption, and accurately estimate the power based on the power model. This paper reviews the current computer system power model, and classifies introduction these energy consumption model, and finally make a prospect.
