Our experiments are SimGrid/SMPI v3.10~\cite{ref66} over an homogeneous distributed memory architecture. -This chapter is composed of two parts. The first part, the proposed frequency scaling selection algorithm uses the energy model of the Rauber and Rünger \cite{ref47} and is compared to Rauber and Rünger's method. The comparison results show that our algorithm gives better energy-time trade-off. In the second part, a new energy model that takes into account both the communication and computation times of the MPI programs running over a homogeneous cluster is developed. +This chapter is composed of two parts.
