PMMP: A power model for multi-core processor systems

Today, power is increasingly becoming the key limitation in CPU performance; therefore, power consumption is an important issue for computer manufacturers. While manufacturers main design challenge is reducing the power to decrease heat and energy consumption, they are also concerned with designing smaller devices which will work longer while consuming the same amount of energy without losing the performance. In this research we have focused on power consumption optimization. The goal is to answer the following question: Can we find a method to save energy and CPU expenses, based on scheduling, without a significant loss in performance? We create a power model for multiple cores as opposed to a single core. Through extensive validation using SPECCPU2006 benchmarks, we show that the model, developed by the proposed methodology, improves energy delay by 16%.
