virtual Isorropia::Epetra::Operator::~Operator ( )

virtual

Destructor.

Reimplemented from Isorropia::Operator.

Member Function Documentation

void Isorropia::Epetra::Operator::setParameters ( const Teuchos::ParameterList & paramlist )

virtual

setParameters() is an internal method which handles the parameters from a Teuchos::ParameterList object.

Implements Isorropia::Operator.

Teuchos::RCP<Isorropia::Epetra::CostDescriber>& Isorropia::Epetra::Operator::getCosts ( )

inline

Get the cost object.

virtual void Isorropia::Epetra::Operator::compute ( bool forceRecomputing )

pure virtual

Method which does the work of computing a new partitioning/coloring/ordering, depending on the child class used.

Parameters

forceRecomputing Optional argument defaults to false. Depending on the implementation, compute() should only perform a computation the first time it is called, and subsequent repeated calls are no-ops. If the user's intent is to re-compute the results (e.g., if parameters or other inputs have been changed), then setting this flag to true will force a new result to be computed.

Implements Isorropia::Operator.

Implemented in Isorropia::Epetra::Partitioner, Isorropia::Epetra::Colorer, Isorropia::Epetra::Partitioner2D, Isorropia::Epetra::Orderer, and Isorropia::Epetra::LevelScheduler.

bool Isorropia::Epetra::Operator::alreadyComputed ( ) const

inlinevirtual

Query whether compute_operation() has already been called.

Implements Isorropia::Operator.

int Isorropia::Epetra::Operator::numProperties ( ) const

inlinevirtual

Return the number of different values used for "properties".

For example, the number of colors or the number of parts used for the overall graph/matrix.

Returns: Global number of values for properties

Remarks: Infact, it returns the upper bound of the interval of taken values. For example, for the colors "1,2,4" , it will return "4"

Implements Isorropia::Operator.

int Isorropia::Epetra::Operator::numLocalProperties ( ) const

inlinevirtual

Return the number of different values used for "properties" for this process only.

Returns: Local number of values for properties

Implements Isorropia::Operator.

virtual const int& Isorropia::Epetra::Operator::operator[] ( int myElem ) const

virtual

Return the new partition ID for a given element that resided locally in the old operation.

Implements Isorropia::Operator.

virtual int Isorropia::Epetra::Operator::numElemsWithProperty ( int property ) const

virtual

Return the number of elements in a given partition.

Implements Isorropia::Operator.

virtual void Isorropia::Epetra::Operator::elemsWithProperty	(	int	property,
		int *	elementList,
		int	len
	)		const

virtual

Fill user-allocated list (of length len) with the global element ids to be located in the given partition.

		int *	array
	)		const

virtual

Copy a part of the property array.

Parameters

len	[in] of the array given by the user.
size	[out] Number of elements in the array.
array	[out] Array of properties. Allocated by the user with a size of at least `len` elements.

Remarks: Memory space which is not useful in the array is not initialized or used in this method.

See Also: Isorropia::Operator::extractPropertiesView()

Implements Isorropia::Operator.

virtual int Isorropia::Epetra::Operator::extractPropertiesView	(	int &	size,
		const int *&	array
	)		const

virtual

Give access of the property array that is owned by the current processor.

Parameters

size	[out] Number of elements in the array.
array	[out] Pointer to the the properties array inside the object.

Remarks: This pointer is only significant if the object still exists. Otherwise, you must use
