Amdahl's Efficiency indicates serial computation and can be computed as follows:
Amdahl's Efficiency = ( max( runtime ) - avg( idling time of OpenMP threads ) ) / max( runtime )
where average idling time of OpenMP threads considers that threads are idling if only master thread is working and can be computed as sum over all processes( serial computation * ( number of threads per process - 1 ) ) / number of all available threads
