* @class vtkSubCommunicator
|
||
|
|
* @brief Provides communication on a process group.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* This class provides an implementation for communicating on process groups.
|
||
|
|
* In general, you should never use this class directly. Instead, use the
|
||
|
|
* vtkMultiProcessController::CreateSubController method.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* @bug
|
||
|
|
* Because all communication is delegated to the original communicator,
|
||
|
|
* any error will report process ids with respect to the original
|
||
|
|
* communicator, not this communicator that was actually used.
|
||
|

|
* vtkCommunicator, vtkMultiProcessController
|
||
|
|
*
|
||
|
|
* @par Thanks:
|
||
|
|
* This class was originally written by Kenneth Moreland (kmorel@sandia.gov)
|
||
|
|
* from Sandia National Laboratories.
