“…Considering only MPI‐1 and MPI‐2, the second one was the one with the worst results. Similar behavior was observed by Lorenzon et al In addition, the pseudo‐applications which presented the worst results for MPI are the only ones who have a higher percentage of memory usage than CPU usage during execution . In this way, we can conclude that memory accesses have a strong negative impact on energy consumption.…”

“…Using 20 parallel tasks, JA and GS with MPI‐2 run about 2×10 12 of total instructions, against 500×10 9 for MPI‐1 and about 15×10 9 for OpenMP and PThreads. As the work of Lorenzon et al shows, these pseudo‐applications are among those that do a lot of communication among tasks and in MPI this communication is very costly, which increases the number of instructions.…”

“…There are four basic techniques for minimizing power dissipation in embedded electronic systems: voltage scaling, frequency scaling, power gating, and clock gating. As is well known, many theoretical considerations, as well as practical experiments, have shown that the energy consumed by electronic circuits strongly depends on the operating frequency [2,8,9,[15][16][17][18].…”

“…IV. METHODOLOGY Benchmarks: We consider ten parallel applications already parallelized from [20], which have different communication demands and operations to exchange data, as depicted in Table I. They are classified into two classes: High Communication (HC) and Low Communication (LC) and were executed with a small input set, used for the learning phase, and a regular input set (Table I), used to evaluate BALDER.…”
