Constructor & Destructor Documentation

vtkBlockDistribution::vtkBlockDistribution	(	vtkIdType	N,
		vtkIdType	P
	)

inline

Create a block distribution with N elements on P processors.

Definition at line 88 of file vtkBlockDistribution.h.

vtkIdType vtkBlockDistribution::GetNumElements ( )

inline

Retrieves the number of elements for which this block distribution was built.

Definition at line 43 of file vtkBlockDistribution.h.

vtkIdType vtkBlockDistribution::GetNumProcessors ( )

inline

Retrieves the number of processors for which this block distribution was built.

Definition at line 49 of file vtkBlockDistribution.h.

vtkIdType vtkBlockDistribution::GetBlockSize ( vtkIdType rank )

inline

Get the block size for the processor with the given rank.

This is the number of elements that the processor will store.

Definition at line 95 of file vtkBlockDistribution.h.

vtkIdType vtkBlockDistribution::GetProcessorOfElement ( vtkIdType globalIndex )

inline

Retrieve the process number in [0, GetNumProcessors()) where the element with the given global index will be located.

Definition at line 104 of file vtkBlockDistribution.h.

vtkIdType vtkBlockDistribution::GetLocalIndexOfElement ( vtkIdType globalIndex )

inline

Retrieve the local index (offset) on the processor determined by GetProcessorOfElement that refers to the given global index.

Definition at line 123 of file vtkBlockDistribution.h.

vtkIdType vtkBlockDistribution::GetFirstGlobalIndexOnProcessor ( vtkIdType rank )

inline

Retrieve the first global index stored on the processor with the given rank.

Definition at line 132 of file vtkBlockDistribution.h.

vtkIdType vtkBlockDistribution::GetGlobalIndex	(	vtkIdType	localIndex,
		vtkIdType	rank
	)

inline

Retrieve the global index associated with the given local index on the processor with the given rank.
