Parallel Efficiency (PE) reveals the inefficiency in processes and threads utilization. These are measured with Amdahl's Efficiency and MPI Efficiency and OpenMP Efficiency, and PE can be computed as a product of these three sub-metrics:
PE = Amdahl's Efficiency * MPI Efficiency * OpenMP Efficiency
Amdahl's Efficiency indicates if application is bound by serial part of application, MPI Efficiency indicates inefficiencies cased by communication, and OpenMP Efficiency indicates inefficient utilization of OpenMP threads.
