Preprocessing of DAG Tasks based on Optimal Frequency Determination Method

Abstract

Abstract. With the application of multi-core processor, the data processing ability has been improved. More and more scholars pay more attention to the processing optimization of the task with the constraint of each other. Marco E.T. Gerards et al. have given the way to choose the optimal clock frequencies that minimize the energy consumption for global DVFS when processing real-time tasks. This article presents a kind of DAG task preprocessing, then the energy consumption reduces 7%.
