By becoming more popular and complex, HPC systems like computational grids, clusters, clouds and the supporting data centers are now changed to remarkable energy consumers. A wide variety of researches, ranging from power-aware hardware design to developing optimized programs and to power-aware job scheduling, have been done hitherto in order to reduce their energy consumption. However, the success of these approaches highly depends to having a precise knowledge about power consumption behavior of the target system. In this paper, some neglected facts are shown about combinational effects of jobs’ and resources’ characteristics on energy consumption rate and define corresponding parameters which make these facts practically utilizable by formulating them as functions of job-machine characteristics. These facts are supported by the experimental analyses on real machines and analytical studies. The outcome of this paper can be exploited to have more energy efficient task mapping process in large-scale heterogeneous computational systems.
