QoS Manager for Energy Efficient Many-Core Operating Systems

Abstract

The oncoming many-core platforms is a hot topic these days, and this next generation hardware sets new focus on energy and thermal awareness. With a more and more dense packing of transistors, the system must be made energy aware to not suffer from overheating and energy waste. As a step towards increased energy efficiency, we intend to add the notion of QoS handling to the OS level and to applications. We suggest the design of a QoS manager as a plug-in OS extension capable of providing applications with the necessary resources leading to better energy efficiency.
