Amdahl's Efficiency

Amdahl's Efficiency indicates serial computation and can be computed as follows:

Amdahl's Efficiency = parallel execution time / total runtime

where parallel execution time is a time spent in OpenMP parallel regions. Amdahl's Efficiency computed per MPI rank, significant difference between MAX and MIN values indicate that some process have bigger serialization part than others.
