MPI Parallel Efficiency

MPI Parallel Efficiency (MPE) reveals the inefficiency in MPI processes. MPE can be computed directly or as a product of MPI Load Balance Efficiency and MPI Communication Efficiency :

\begin{eqnarray*}MPE=\frac{avg(time\; outside\; of\; MPI)}{max(runtime)} \end{eqnarray*}

= MPI Load Balance Efficiency ⋅ MPI Communication Efficiency
