Detailed Description

template<class Scalar = SmootherPrototype<>::scalar_type, class LocalOrdinal = typename SmootherPrototype<Scalar>::local_ordinal_type, class GlobalOrdinal = typename SmootherPrototype<Scalar, LocalOrdinal>::global_ordinal_type, class Node = typename SmootherPrototype<Scalar, LocalOrdinal, GlobalOrdinal>::node_type>
class MueLu::Ifpack2Smoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Class that encapsulates Ifpack2 smoothers.

This class creates an Ifpack2 preconditioner factory. The factory creates a smoother based on the type and ParameterList passed into the constructor. See the constructor for more information.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

void MueLu::Ifpack2Smoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::SetParameterList ( const Teuchos::ParameterList & paramList )

virtual

Set parameters from a parameter list and return with default values.

template<class Scalar , class LocalOrdinal , class GlobalOrdinal , class Node >

void MueLu::Ifpack2Smoother< Scalar, LocalOrdinal, GlobalOrdinal, Node >::Setup ( Level & currentLevel )

virtual

Set up the smoother.

This creates the underlying Ifpack2 smoother object, copies any parameter list options supplied to the constructor to the Ifpack2 object, and computes the preconditioner.

TODO The eigenvalue estimate should come from A_, not the Ifpack2 parameter list.

Implements MueLu::SmootherPrototype< Scalar, LocalOrdinal, GlobalOrdinal, Node >.

		const MultiVector &	B,
		bool	InitialGuessIsZero = `false`
	)		const

virtual

Apply the preconditioner.

Solves the linear system AX=B using the constructed smoother.

Parameters

X	initial guess
B	right-hand side
InitialGuessIsZero	(optional) If false, some work can be avoided. Whether this actually saves any work depends on the underlying Ifpack2 implementation.
