Description

Energy-aware scheduling (EAS) introduced a simply, yet at that time, effective energy model to help guide task scheduling decisions and DVFS policies. As CPU core micro-architecture has evolved the error bars on the energy model to grow potentially leading to sub-optimal task placement. Are we getting to the point where we need to enhance the energy model, or look at new ways to bias task placement decisions?
