Detailed Description

scalable collective communication for a subset of members of a parallel VTK application

This class provides scalable broadcast, reduce, etc. using only a vtkMultiProcessController. It does not require MPI. Users are vtkPKdTree and vtkDistributedDataFilter.

Attention

This class will be deprecated soon. Instead of using this class, use the collective and subgrouping operations now built into vtkMultiProcessController. The only reason this class is not deprecated already is because vtkPKdTree relies heavily on this class in ways that are not easy to work around. Since vtkPKdTree is due for a major overhaul anyway, we are leaving things the way they are for now.

int vtkSubGroup::Initialize	(	int	p0,
		int	p1,
		int	me,
		int	tag,
		vtkCommunicator *	c
	)

Initialize a communication subgroup for the processes with rank p0 through p1 of the given communicator. (So vtkSubGroup is limited to working with subgroups that are identified by a contiguous set of rank IDs.) The third argument is the callers rank, which must in the range from p0 through p1.
