摘　　要：提出一种面向高性能业务主机基于动态电压调节技术的能耗优化方法,该方法测量应用程序在不同频率下的性能和能耗,并建立性能约束下的能耗优化模型,优化业务系统的能耗;利用功率计测试了3种典型计算机系统在不同频率下运行程序的能耗;根据测试数据和系统能耗优化模型,对能耗优化方法进行了实验验证,结果显示:对于不同的时间约束条件和程序,所提方法可以节省16%的系统能耗.An energy optimization method based on DVFS（dynamic voltage frequency scaling）for the operational systems was presented.The running time and energy consumption in different frequencies for operational applications were measured and the energy consumption was reduced under an energy model confined by time constraints.The energy consumptions in three representative computer platforms were obtained by apower meter.From the data of energy consumption and time,the energy model was used to compute optimizing energy consumption.Experiment results show the largest reduction of energy consumption reaches 16%.
