One Line Summary

Enabling the scheduler to make informed energy-aware scheduling decisions using platform energy/performance models.

Abstract

Energy-aware scheduling proposals have been discussed numerous times over the last couple of years. Optimizing for energy is difficult and the techniques vary from between architectures/platforms. Some may be beneficial on some platforms while being harmful on others. A potential solution to this problem is to provide a relatively simple energy/performance model for the platform to enable the scheduler to make informed decisions.
