Detailed Description

helper for the vtkGraph class that allows the graph to be distributed across multiple memory spaces.

A distributed graph helper can be attached to an empty vtkGraph object to turn the vtkGraph into a distributed graph, whose vertices and edges are distributed across several different processors. vtkDistributedGraphHelper is an abstract class. Use a subclass of vtkDistributedGraphHelper, such as vtkPBGLDistributedGraphHelper, to build distributed graphs.

The distributed graph helper provides facilities used by vtkGraph to communicate with other processors that store other parts of the same distributed graph. The only user-level functionality provided by vtkDistributedGraphHelper involves this communication among processors and the ability to map between "distributed" vertex and edge IDs and their component parts (processor and local index). For example, the Synchronize() method provides a barrier that allows all processors to catch up to the same point in the code before any processor can leave that Synchronize() call. For example, one would call Synchronize() after adding many edges to a distributed graph, so that all processors can handle the addition of inter-processor edges and continue, after the Synchronize() call, with a consistent view of the distributed graph. For more information about manipulating (distributed) graphs, see the vtkGraph documentation.
