Software products are usually required to meet some static or dynamic properties. Well-known examples of dynamic properties are the program execution time and the related goal of software performance optimization. Because of the increasing importance of ecological and environmental issues, also the energy consumption of software products is a dynamic property of increasing importance. Modern computer systems already provide features, such as multicores and voltage-frequency scaling, to support the reduction of the energy consumption of software. However, a low program execution time and a good energy efficiency might be conflicting goals and it may be difficult so simultaneously reduce the program execution time and the energy consumption. In this article, the relation between energy effort and execution time of software is investigated and a software tuning method for task-based programs is proposed, which appraises different program versions and different task structures concerning their execution time and energy consumption with the objective to pick the most favorable solution.
