Detailed Description

Distribute data among processors.

This filter redistributes data among processors in a parallel application into spatially contiguous vtkUnstructuredGrids. The execution model anticipated is that all processes read in part of a large vtkDataSet. Each process sets the input of filter to be that DataSet. When executed, this filter builds in parallel a k-d tree, decomposing the space occupied by the distributed DataSet into spatial regions. It assigns each spatial region to a processor. The data is then redistributed and the output is a single vtkUnstructuredGrid containing the cells in the process' assigned regions.

This filter is sometimes called "D3" for "distributed data decomposition".

Enhancement: You can set the k-d tree decomposition, rather than have D3 compute it. This allows you to divide a dataset using the decomposition computed for another dataset. Obtain a description of the k-d tree cuts this way:

vtkBSPCuts *cuts = D3Object1->GetCuts()

And set it this way:

D3Object2->SetCuts(cuts)

It is desirable to have a field array of global node IDs for two reasons:

  1. When merging together sub grids that were distributed across processors, global node IDs can be used to remove duplicate points and significantly reduce the size of the resulting output grid. If no such array is available, D3 will use a tolerance to merge points, which is much slower.
  2. If ghost cells have been requested, D3 requires a global node ID array in order to request and transfer ghost cells in parallel among the processors. If there is no global node ID array, D3 will in parallel create a global node ID array, and the time to do this can be significant.

D3 uses vtkPointData::GetGlobalIds to access global node ids from the input. If none is found, and ghost cells have been requested, D3 will create a temporary global node ID array before acquiring ghost cells.

It is also desirable to have global element IDs (vtkCellData::GetGlobalIds). However, if they don't exist D3 can create them relatively quickly.

Warning
The Execute() method must be called by all processes in the parallel application, or it will hang. If you are not certain that your pipeline will execute identically on all processors, you may want to use this filter in an explicit execution mode.

vtkPKdTree* vtkDistributedDataFilter::GetKdtree ( )

Get a pointer to the parallel k-d tree object.

Required for changing default behavior for region assignment, changing default depth of tree, or other tree building default parameters. See vtkPKdTree and vtkKdTree for more information about these options. NOTE: Changing the tree returned by this method does NOT change the d3 filter. Make sure to call Modified() on the d3 object if you want it to re-execute.

virtual void vtkDistributedDataFilter::RetainKdtreeOn ( )
virtual

When this filter executes, it creates a vtkPKdTree (K-d tree) data structure in parallel which divides the total distributed data set into spatial regions.

The K-d tree object also creates tables describing which processes have data for which regions. Only then does this filter redistribute the data according to the region assignment scheme. By default, the K-d tree structure and it's associated tables are deleted after the filter executes. If you anticipate changing only the region assignment scheme (input is unchanged) and explicitly re-executing, then RetainKdTreeOn, and the K-d tree structure and tables will be saved. Then, when you re-execute, this filter will skip the k-d tree build phase and go straight to redistributing the data according to region assignment. See vtkPKdTree for more information about region assignment.

Each cell in the data set is associated with one of the spatial regions of the k-d tree decomposition.

In particular, the cell belongs to the region that it's centroid lies in. When the new vtkUnstructuredGrid is created, by default it is composed of the cells associated with the region(s) assigned to this process. If you also want it to contain cells that intersect these regions, but have their centroid elsewhere, then set this variable on. By default it is off.

You can set the k-d tree decomposition, rather than have D3 compute it.

This allows you to divide a dataset using the decomposition computed for another dataset. Obtain a description of the k-d tree cuts this way:

vtkBSPCuts *cuts = D3Object1->GetCuts()

And set it this way:

D3Object2->SetCuts(cuts)

Definition at line 253 of file vtkDistributedDataFilter.h.

void vtkDistributedDataFilter::SetCuts ( vtkBSPCuts cuts)
void vtkDistributedDataFilter::SetUserRegionAssignments ( const int map,
int  numRegions 
)

vtkBSPCuts doesn't have information about process assignments for the cuts.

Typically D3 filter simply reassigns the processes for each cut. However, that may not always work, sometimes the processes have be pre-assigned and we want to preserve that partitioning. In that case, one sets the region assignments explicitly. Look at vtkPKdTree::AssignRegions for details about the arguments. Calling SetUserRegionAssignments(nullptr, 0) will revert to default behavior i.e. letting the KdTree come up with the assignments.

AssignBoundaryCellsToOneRegion turns off both ClipCells and IncludeAllIntersectingCells. Each cell will be included in exactly one process' output unstructured grid.
