These tradeoff distance between energy consumption -\subsection{Experiments with different static and dynamic powers consumption scenarios} +\subsection{Experiments with different static power scenarios} \label{sec.pow_sen} In section \ref{sec.grid5000}, since it was not possible to measure the static power consumed by a CPU, the static power was assumed to be equal to 20\% of the measured dynamic power. This power is consumed during the whole execution time, during computation and communication times. Therefore, when the DVFS operations are applied by the scaling algorithm and the CPUs' frequencies lowered, the execution time might increase and consequently the consumed static energy will be increased too.
