Transfer Efficiency

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

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

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