Detailed Description

Interface for mpi synchronizers.

Note:

This class and related functions are needed for the way the cluster version of Fuego, BlueFuego, is currently implemented. The design is under dispute, because it causes intrusive changes to other classes and breaks encapsulation of their implementation. See http://sourceforge.net/apps/trac/fuego/ticket/32 for details.
