Abstract:

With development of cloud computing and big data, the energy consumption of data center becomes more and more serious. It is necessary to establish a precise model of energy consumption for the computing node of the data center. In the most previous studies, linear system utilization is taken to establish the models of energy consumption. In order to solve the accuracy insufficient of linear model, a model of energy consumption based on the segmented CPU utilization was proposed when considering the memory and the hard drive at the same time. In the experiment, the inner relationship between the energy consumption and the CPU was found, and a formula of the potential influence of the components was proposed, and the accuracy of the model is verified in both single environment and parallel environment.

Key words: energy model, cloud computing, non-linear model, regression analysis
