// .NAME vtkDummyCommunicator - Dummy controller for single process applications.
|
|
//
|
|
// .SECTION Description
|
|
//
|
|
// This is a dummy communicator, which can be used by applications that always
|
|
// require a controller but are also compiled on systems without threads or MPI.
|
|
// Because there is always only one process, no real communication takes place.
