ratio

public static double ratio(Partitioner partitioner)

Calculate the computation to communication ratio of the application. Where the computation is total work of all the filters in the steady-state and the communication is the number of items sent between slices.

Parameters:

partitioner - The partitioner we used to slice the graph.

Returns:

The computation to communication ratio.
