Hybrid Parallel Efficiency

Hybrid Parallel Efficiency (HPE) reveals the inefficiency in processes and threads utilization. These are measured with Hybrid Load Balance Efficiency and Hybrid Communication Efficiency, and HPE can be computed directly or as a product of these two sub-metrics:

$\begin{eqnarray*}HPE=\frac{avg(computation\; time)}{max(runtime)} \end{eqnarray*}$
