Detailed Description

Creates the parallel distribution map by describing the source and target objects using box shapes.

A single box is created for the source object, which is then split using 2x2x2 refinement based on the number of remote target objects that overlap. The refinement is local between communicating processor pairs, where the refinement continues until a threshold number of remote target objects per source box is achieved.
