Abstract—High energy consumption of data centers has become a great obstacle to the development of cloud computing. This paper mainly focuses on how to improve the energy efficiency of servers in a data center by appropriate task scheduling strategies. Based on MapReduce, Google’s massive data processing framework, a new energy-efficient task scheduling model is proposed in this paper. To solve this model, we put forward an effective genetic algorithm with practical encoding and decoding methods and specially designed genetic operators. Meanwhile, with a view to accelerating this algorithm’s convergent speed as well as enhancing its searching ability, a local search operator is introduced. Finally, the experiments show that the proposed algorithm is effective and efficient.
