Member Function Documentation

int Ifpack_OverlappingPartitioner::NumLocalParts ( ) const

inlinevirtual

Returns the number of computed local partitions.

Implements Ifpack_Partitioner.

Definition at line 98 of file Ifpack_OverlappingPartitioner.h.

int Ifpack_OverlappingPartitioner::OverlappingLevel ( ) const

inlinevirtual

Returns the overlapping level.

Implements Ifpack_Partitioner.

Definition at line 104 of file Ifpack_OverlappingPartitioner.h.

int Ifpack_OverlappingPartitioner::operator() ( int MyRow ) const

inlinevirtual

Returns the local non-overlapping partition ID of the specified row.

Returns the non-overlapping partition ID of the specified row.

Parameters

MyRow - (In) local row numbe

Returns: Local ID of non-overlapping partition for MyRow.

Implements Ifpack_Partitioner.

Definition at line 117 of file Ifpack_OverlappingPartitioner.h.

int Ifpack_OverlappingPartitioner::operator()	(	int	i,
		int	j
	)		const

inlinevirtual

Returns the local overlapping partition ID of the j-th node in partition i.

Implements Ifpack_Partitioner.

Definition at line 126 of file Ifpack_OverlappingPartitioner.h.

int Ifpack_OverlappingPartitioner::NumRowsInPart ( const int Part ) const

inlinevirtual

Returns the number of rows contained in specified partition.

Implements Ifpack_Partitioner.

Definition at line 138 of file Ifpack_OverlappingPartitioner.h.

int Ifpack_OverlappingPartitioner::RowsInPart	(	const int	Part,
		int *	List
	)		const

inlinevirtual

Copies into List the rows in the (overlapping) partition Part.

Implements Ifpack_Partitioner.

Definition at line 143 of file Ifpack_OverlappingPartitioner.h.

const int* Ifpack_OverlappingPartitioner::NonOverlappingPartition ( ) const

inlinevirtual

Returns a pointer to the integer vector containing the non-overlapping partition ID of each local row.

Implements Ifpack_Partitioner.

Definition at line 151 of file Ifpack_OverlappingPartitioner.h.

int Ifpack_OverlappingPartitioner::SetParameters ( Teuchos::ParameterList & List )

virtual

Sets all the parameters for the partitioner.

The supported parameters are:

"partitioner: overlap" (int, default = 0).
"partitioner: local parts" (int, default = 1).
"partitioner: print level" (int, default = 0).

Implements Ifpack_Partitioner.

Definition at line 72 of file Ifpack_OverlappingPartitioner.cpp.

virtual int Ifpack_OverlappingPartitioner::SetPartitionParameters ( Teuchos::ParameterList & List )

pure virtual

Sets all the parameters for the partitioner.

This function is used by derived classes to set their own parameters. These classes should not derive SetParameters(), so that common parameters can be set just once.

Implemented in Ifpack_LinePartitioner, Ifpack_EquationPartitioner, Ifpack_METISPartitioner, Ifpack_UserPartitioner, Ifpack_GreedyPartitioner, and Ifpack_LinearPartitioner.
