Detailed Description

A generic filter that can reduce any type of dataset using any reduction algorithm.

A generic filter that can reduce any type of dataset using any reduction algorithm. Actual reduction is performed by running the PreGatherHelper and PostGatherHelper algorithms. The PreGatherHelper runs on each node in parallel. Next the intermediate results are gathered to the root node. Then the root node then runs the PostGatherHelper algorithm to produce a single result. The PostGatherHelper must be an algorithm that takes multiple input connections and produces a single reduced output.

In addition to doing reduction the PassThrough variable lets you choose to pass through the results of any one node instead of aggregating all of them together.

◆ SetReductionMode()

virtual void vtkReductionFilter::SetReductionMode ( int )

virtual

Get/Set the Reduction Mode.

REDUCE_ALL_TO_ONE is the default behavior. It reduces all data on a single node, while other nodes keeps their data. MOVE_ALL_TO_ONE Reduce all data on a single node while other nodes delete their data. ALL NODES Reduce all data on all nodes.

◆ GetReductionMode()

virtual int vtkReductionFilter::GetReductionMode ( )

virtual

Get/Set the Reduction Mode.

REDUCE_ALL_TO_ONE is the default behavior. It reduces all data on a single node, while other nodes keeps their data. MOVE_ALL_TO_ONE Reduce all data on a single node while other nodes delete their data. ALL NODES Reduce all data on all nodes.

◆ SetReductionProcessId()

virtual void vtkReductionFilter::SetReductionProcessId ( int )

virtual

Get/Set the node to reduce to, default is 0.

Not used with REDUCE_ALL_TO_ALL Reduction mode

◆ GetReductionProcessId()

virtual int vtkReductionFilter::GetReductionProcessId ( )

virtual

Get/Set the node to reduce to, default is 0.

Not used with REDUCE_ALL_TO_ALL Reduction mode

◆ SetPreGatherHelper()

void vtkReductionFilter::SetPreGatherHelper ( vtkAlgorithm * )

Get/Set the pre-reduction helper.

Pre-Reduction helper is an algorithm that runs on each node's data before it is sent to the root.

◆ SetPreGatherHelperName()

void vtkReductionFilter::SetPreGatherHelperName ( const char * )

Get/Set the pre-reduction helper.

Pre-Reduction helper is an algorithm that runs on each node's data before it is sent to the root.

virtual vtkAlgorithm* vtkReductionFilter::GetPreGatherHelper ( )

virtual

Get/Set the pre-reduction helper.

Pre-Reduction helper is an algorithm that runs on each node's data before it is sent to the root.

◆ SetPostGatherHelper()

void vtkReductionFilter::SetPostGatherHelper ( vtkAlgorithm * )

Get/Set the reduction helper.

Reduction helper is an algorithm with multiple input connections, that produces a single output as the reduced output. This is run on the root node to produce a result from the gathered results of each node.

◆ SetPostGatherHelperName()

void vtkReductionFilter::SetPostGatherHelperName ( const char * )

Get/Set the reduction helper.

Reduction helper is an algorithm with multiple input connections, that produces a single output as the reduced output. This is run on the root node to produce a result from the gathered results of each node.

◆ GetPostGatherHelper()

virtual vtkAlgorithm* vtkReductionFilter::GetPostGatherHelper ( )

virtual

Get/Set the reduction helper.

Reduction helper is an algorithm with multiple input connections, that produces a single output as the reduced output. This is run on the root node to produce a result from the gathered results of each node.

◆ SetController()

void vtkReductionFilter::SetController ( vtkMultiProcessController * )

Get/Set the MPI controller used for gathering.

◆ SetPassThrough()

virtual void vtkReductionFilter::SetPassThrough ( int )

virtual

Get/Set the PassThrough flag which (when set to a nonnegative number N) tells the filter to produce results that come from node N only.

The data from that node still runs through the PreReduction and PostGatherHelper algorithms.

◆ GetPassThrough()

virtual int vtkReductionFilter::GetPassThrough ( )

virtual

Get/Set the PassThrough flag which (when set to a nonnegative number N) tells the filter to produce results that come from node N only.

The data from that node still runs through the PreReduction and PostGatherHelper algorithms.

◆ SetGenerateProcessIds()

virtual void vtkReductionFilter::SetGenerateProcessIds ( int )

virtual

When set, a new array vtkOriginalProcessIds will be added to the output of the the pre-gather helper (or input, if no pre-gather helper is set).

The values in the array indicate the process id. Note that the array is added only if the number of processes is > 1.

◆ GetGenerateProcessIds()

virtual int vtkReductionFilter::GetGenerateProcessIds ( )

virtual

When set, a new array vtkOriginalProcessIds will be added to the output of the the pre-gather helper (or input, if no pre-gather helper is set).

◆ GatherSelection()

int vtkReductionFilter::GatherSelection	(	vtkSelection *	sendData,
		std::vector< vtkSmartPointer< vtkDataObject >> &	receiveData,
		int	destProcessId
	)

protected

Gather for vtkSelection sendData is a vtkSelection while receiveData is a vector of NumberOfProcesses vtkSelections.

Selections are gathered on destProcessId
