Detailed Description

template<typename CELL_TYPE>
class LibGeoDecomp::CollectingWriter< CELL_TYPE >

Adapter class whose purpose is to use legacy Writer objects together with a DistributedSimulator.

Good for testing, but doesn't scale, as all memory is concentrated on one node and IO is serialized to that node. Use with care!
