Detailed Description

redistributes input dataset into requested number of partitions

vtkRedistributeDataSetFilter is intended for redistributing data in a load balanced fashion. The load balancing attempts to balance the number of cells per target partition approximately. It uses a DIY-based kdtree implementation that builds balances the cell centers among requested number of partitions. Current implementation only supports power-of-2 target partition. If a non-power of two value is specified for NumberOfPartitions, then the load balancing simply uses the power-of-two greater than the requested value. The bounding boxes for the kdtree leaf nodes are then used to redistribute the data.

Alternatively a collection of bounding boxes may be provided that can be used to distribute the data instead of computing them (see UseExplicitCuts and SetExplicitCuts). When explicit cuts are specified, it is possible use those cuts strictly or to expand boxes on the edge to fit the domain of the input dataset. This can be controlled by ExpandExplicitCutsForInputDomain.

The filter allows users to pick how cells along the boundary of the cuts either automatically generated or explicitly specified are to be distributed using BoundaryMode. One can choose to assign those cells uniquely to one of those regions or duplicate then on all regions or split the cells (using vtkTableBasedClipDataSet filter). When cells are duplicated along the boundary, the filter will mark the duplicated cells as vtkDataSetAttributes::DUPLICATECELL correctly on all but one of the partitions using the ghost cell array (

See also
vtkDataSetAttributes::GhostArrayName).

Besides redistributing the data, the filter can optionally generate global cell ids. This is provided since it relative easy to generate these on when it is known that the data is spatially partitioned as is the case after this filter has executed.

Supported Data Types

vtkRedistributeDataSetFilter is primarily intended for unstructured datasets i.e. vtkUnstructuredGrid, vtkPolyData and composite datasets comprising of the same. It will work when applied to structured datasets as well, however, it results in conversion of the dataset to an unstructured grid – which is often not suitable. Also, other redistribution and load balancing strategies can be applied to structured data which may be more efficient and hence should be preferred over using this filter.

For composite datasets, the filter supports vtkPartitionedDataSet and vtkPartitionedDataSetCollection. When input is a vtkPartitionedDataSetCollection, you can set LoadBalanceAcrossAllBlocks to true to build the load balancing KdTree using all vtkPartitionedDataSets in the collection. Default is load balance each vtkPartitionedDataSet separately.

For vtkMultiBlockDataSet, the filter internally uses vtkDataAssemblyUtilities to convert the vtkMultiBlockDataSet to a vtkPartitionedDataSetCollection and back.

The advantage of doing that is each partition that the input dataset was split into can be individually accessed. Otherwise, when the number of partitions generated is greater than the number of ranks, a rank with more than one partition will use vtkAppendFilter to merge the multiple partitions into a single unstructured grid.

The output dataset type is always vtkUnstructuredGrid when PreservePartitionsInOutput is false and always a vtkPartitionedDataSet when PreservePartitionsInOutput is true.

Default is false i.e. the filter will generate a single vtkUnstructuredGrid.

Otherwise, when the number of partitions generated is greater than the number of ranks, a rank with more than one partition will use vtkAppendFilter to merge the multiple partitions into a single unstructured grid.

Otherwise, when the number of partitions generated is greater than the number of ranks, a rank with more than one partition will use vtkAppendFilter to merge the multiple partitions into a single unstructured grid.

The output dataset type is always vtkUnstructuredGrid when PreservePartitionsInOutput is false and always a vtkPartitionedDataSet when PreservePartitionsInOutput is true.

Default is false i.e. the filter will generate a single vtkUnstructuredGrid.

◆ PreservePartitionsInOutputOff()

virtual void vtkRedistributeDataSetFilter::PreservePartitionsInOutputOff ( )
virtual

When set to true (default is false), this filter will generate a vtkPartitionedDataSet as the output.

The advantage of doing that is each partition that the input dataset was split into can be individually accessed. Otherwise, when the number of partitions generated is greater than the number of ranks, a rank with more than one partition will use vtkAppendFilter to merge the multiple partitions into a single unstructured grid.

◆ SetEnableDebugging()

protectedvirtual

This method is called to generate the partitions for the input dataset.

◆ SplitDataSet()

The returned vtkPartitionedDataSet must have exactly as many partitions as the number of vtkBoundingBoxes in the cuts vector with each partition matching the bounding box at the matching index.

Note, this method duplicates cells that lie on the boundaries and adds cell arrays that indicate cell ownership and flags boundary cells.
