针对数据中心的计算节点建立精密的能耗模型来预测能耗状况很有必要.为了解决线性模型准确性不足的问题,提出了一种基于分段式CPU利用率的能耗模型,并且加入了内存和硬盘因素.在实验中发现了其他部件的耗能与CPU的内在联系,给出了潜在影响公式.随后,在单机环境和并行环境下验证了模型的准确性.
In order to solve the problem of lack of accuracy of the linear model, this paper proposed a model of energy consumption based on the utilization of the sectioned CPU, and added a Memory and hard disk factors in the experiment found that the other components of the CPU power consumption and the inherent link to give the potential impact formula.Then, in a single environment and parallel environment to verify the accuracy of the model.
