Dynamically changing CPU voltage and frequency have been shown to greatly save the processor energy. These adjustments can be done at specific power management points (PMPs), which are not without overheads. In this work we study the e#ect of di#erent overheads on both time and energy; these can be seen as the overhead of computing the new speed, and then the overhead of dynamically adjusting the speed. We propose a theoretical solution for choosing the granularity of inserting PMPs in a program taking into consideration such overheads. We validate our theoretical results and show that the accuracy of the theoretical model is between zero and five management points of simulation results
