 Figure 6 shows that the running time of this benchmark substantially decreases with the number of MPI-processes. The decrease in running time with the number of threads is less dominant. However, other applications may exhibit a different behavior. Figure 6 shows that the running time of this benchmark substantially decreases with the number of MPI-processes.
