Transfer Efficiency

Transfer Efficiency (TE) measures inefficiencies due to time spent in data transfers:

$\begin{eqnarray*}TE=maximum\; across\; processes( \frac{total\; runtime\; on\; ideal\; network}{maximum\; across\; processes ( total\; measured\; runtime )} ) \end{eqnarray*}$

where total run-time on ideal network is a runtime without detected by Scalasca waiting time and MPI I/O time.
