Research On Resource Usage And Power Consumption Modeling Of Multi-type Applications In Datacenters

the rapid development of data centers bring enormous computing resources to the society,also lead to huge energy consumption at the same time.The premise of solving the energy consumption problem of datacenters is to establish a reliable power consumption model for datacenters.This thesis obtains from the approximate computing applications,using loop perforation technique for the application of precision adjustment,this paper also presents a universal quantitative model of program accuracy,and uses this model to quantify the accuracy of application.and tests the hardware resource usage of the application under current precision.The change of the average hardware resource utilization of the application precision changes is also analyzed.Then,we examine the power of server in a wide variety of hardware resource utilization under the condition of different combination.After that we get the power consumption model of server whose input is multi-type hardware resource usage and the output is the server power.The accuracy of the model can reach more than 95%,which can provide guidance for the follow-up datacenter task scheduling and energy management.
