A Power-aware Job Scheduling Algorithm

A power-aware job scheduling algorithm is proposed to increase the energy efficiency of high performance computer by selectively hibernating some idle nodes during periods of low load. The proposed algorithm records the switching logs of nodes' power states, dynamic setting idle nodes to sleeping status. Detailed experimentation using traces from the Parallel Workloads Archive indicates that the proposed algorithm can achieve effective energy savings with good control on the switching frequency of nodes'power states.
