Detailed Description

template<typename Adapter>
class Zoltan2::CommGraphModel< Adapter >

CommGraphModel defines the interface required for communication graph.

The constructor of the GraphModel can be a global call, requiring all processes in the application to call it. The rest of the methods should be local methods.

The template parameter is an InputAdapter, which is an object that provides a uniform interface for models to the user's input data.

For now, this model only works with GraphAdapter (XpetraCrsGraphAdapter).
