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.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

static vtkSubGroup* vtkSubGroup::New ( )
static
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.
