Energy-efficient scheduling is a significant issue in energy-efficient computing system.At present many researches have focused on Dynamic Voltage and Frequency Scaling(DVFS).However,with the advancement of chip manufacturing technology,the voltage range which CPU core can scale is becoming narrow,so the benefit from DVFS is becoming less and less.This paper proposes a dynamic energy-efficient algorithm based on homogeneous multi-core system.In the condition of lightweight load,tasks are scheduled to single...
