Serialisation Efficiency

Serialisation Efficiency (SerE) measures inefficiency due to idle time within communications, i.e. time where no data is transferred, and is expressed as:

\begin{eqnarray*}SerE=maximum\; across\; processes(\frac{computation\; time}{total\; runtime\; on\; ideal\; network}) \end{eqnarray*}

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