Analytical modeling and simulation of the energy consumption of independent tasks

The estimation and evaluation of the energy consumption of computers is becoming an important issue. In this article, we address the question how the energy consumption for computations can be captured by an analytical energy consumption model. In particular, we address the possibility to reduce the energy consumption by dynamic frequency scaling and model this energy reduction in the context of task execution models. We demonstrate the use of the model by simulating task executions and their energy consumption.
