OpenMP Management Efficiency overhead caused by OpenMP management (e.g. time for foring and joining OpenMP threads) and can be computed as follows:
OpenMP Management Efficiency = max( runtime in OpenMP without management overhead ) / max( runtime in OpenMP )
OpenMP Management Efficiency computed per MPI rank and average across MPIs is shown. Moreover, MIN and MAX values are also available by click on metric bar. Statistics shows if there is considerable difference in runtime management across MPI ranks.
