Abstract
We propose a new DVFS algorithm for enterprise systems that elevates performance as a first order control parameter and manages frequency and voltage as a function of performance requirements. We implement our algorithm on real Intel Westmere platform in Linux and demonstrate its ability to reduce the standard deviation from target performance by more than 90% over state of the art policies while reducing average power by 17%.
