* @class vtkPConvertToMultiBlockDataSet
|
|
* @brief parallel version of vtkConvertToMultiBlockDataSet
|
|
*
|
|
* vtkPConvertToMultiBlockDataSet is the MPI-aware version of
|
|
* vtkConvertToMultiBlockDataSet.
|
|
*
|
|
* The extra work this filter does it to ensure that each `vtkPartitionedDataSet` instance
|
|
* in the input when replaced by a `vtkMultiPieceDataSet in the output,
|
|
* `vtkMultiPieceDataSet` has piece counts across ranks such the output
|
|
* multiblock structure is identical on all ranks. `vtkPartitionedDataSet` /
|
|
* `vtkPartitionedDataSetCollection` doesn't have this requirement and hence the
|
|
* number of partitions in a `vtkPartitionedDataSet` in the input may not be
|
|
* identical on all ranks. Hence, this extra check is needed.
