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...
Programming models based on parallel modules provide portable efficiency on a large range of parallel platforms due to a flexible execution model for the modules. Today, energy efficiency is becoming equally important as execution time efficiency. This article investigates the execution of parallel module programs with respect to energy concerns. In particular, an analytical energy model is extended...
In this article, we use an analytical energy model based on frequency scaling to model the energy consumption of tasks in a fork-join pattern of parallelism. In particular, tasks that may be executed concurrently to each other are considered, and the resulting energy consumption for different processor assignments is investigated. Frequency scaling factors that lead to a minimum energy consumption...
