* @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.
