leads to 18 run states for each program. We use seven MPI programs of the NAS
parallel benchmarks: CG, MG, EP, FT, BT, LU and SP. Figure~(\ref{fig:pred})
presents plots of the real execution times and the simulated ones. The maximum
-normalized error between these two execution times varies between
-\np{0.0073}\AG[]{unit?} to \np{0.031} dependent on the executed benchmark. The
-smallest prediction error was for CG and the worst one was for LU.
