Hybrid Communication Efficiency

Hybrid Communication Efficiency can be evaluated directly by following formula:

\begin{eqnarray*}Hybrid\; Communication\; Efficiency=\frac{max(computation\; time)}{max(runtime)} \end{eqnarray*}

This metric identifies when code is inefficient because it spends a large amount of time communicating rather than performing useful computations.
