They also show that the energy saving percentage decreases when the number of computing nodes increases. This reduction is due to the increase of the communication times compared to the -execution times when the benchmarks are run over a high number of nodes. +execution times when the benchmarks are run over a higher number of nodes. Indeed, the benchmarks with the same class, C, are executed on different numbers of nodes, so the computation required for each iteration is divided by the number of computing nodes.
