Detailed Description

template<class Storage, class LocalOrdinal, class GlobalOrdinal, class Node, template< class, class > class ConcreteSolver>
class Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >

Amesos2 solver adapter for MP::Vector scalar type.

This adapter enables Amesos2 solvers to work with Tpetra matrices and vectors of the Sacado::MP::Vector scalar type by "flattening" these matrices and vectors into ones with a standard (e.g., double) scalar type.

const Teuchos::EVerbosityLevel  verbLevel = Teuchos::Describable::verbLevel_default 
) const
inlinevirtual

Prints the status information about the current solver with some level of verbosity.

virtual void Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >::getTiming ( Teuchos::ParameterList &  timingParameterList) const
inlinevirtual

Extracts timing information from the current solver.

Results are placed in the parameter list timingParameterList

Parameters
timingParameterListAccepts timing information from the current solver

virtual type& Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >::numericFactorization ( void  )
inlinevirtual

Performs numeric factorization on the matrix.

numericFactorization checks first that symbolicFactorization has successfully been called, and if not, calls it before continuing.

Precondition
  • The matrix A must not be null
Postcondition
  • The factors L and U of A are computed
template<class Storage , class LocalOrdinal , class GlobalOrdinal , class Node , template< class, class > class ConcreteSolver>
virtual type& Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >::preOrdering ( void  )
inlinevirtual

Pre-orders the matrix.

Uses the default solver option, unless a solver-specific pre-ordering parameter is given.

virtual void Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >::setA ( const Teuchos::RCP< const Matrix >  a,
EPhase  keep_phase = CLEAN 
)
inlinevirtual

Sets the matrix A of this solver.

Parameters
[in]aAn RCP to a matrix will will be used for future computation steps
[in]keep_phaseThis parameter tells the solver what state it should keep. For example, you may want to replace the matrix but keep the symbolic factorization because you know the structure of the new matrix is the same as the structure of the old matrix. In this case you would pass Amesos2::SYMBFACT as this parameter.

The default value for the second parameter is Amesos2::CLEAN, which means that the internal state of the solver will be completely reset. It will be as if no previous computational steps were performed.

Parameters

[in]keep_phaseThis parameter tells the solver what state it should keep. For example, you may want to replace the matrix but keep the symbolic factorization because you know the structure of the new matrix is the same as the structure of the old matrix.

virtual type& Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >::setParameters ( const Teuchos::RCP< Teuchos::ParameterList > &  parameterList)
inlinevirtual

Set/update internal variables and solver options.

Expects that parameterList be named "Amesos2". That list may contain Amesos2-specific parameters. In addition, it may contain sublist for solver-specific parameters. These sublists should be named according to what is returned by the name() function (i.e. The solver's name when enabling for Amesos2 during configuration).

See each solver interface directly for a list of the supported parameters for that solver.

virtual void Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >::solve ( void  )
inlinevirtual

Solves $ A X = B$ (or $ A^T X = B$ )

solve checks first that numericFactorization has successfully been called, and if not, calls it before continuing.

Precondition
  • The (multi)vectors X and B must not be null
Postcondition
  • The (multi)vector X (given at construction time) contains the solution to the system.

virtual void Amesos2::MPVectorSolverAdapter< Storage, LocalOrdinal, GlobalOrdinal, Node, ConcreteSolver >::solve ( const Teuchos::Ptr< Vector >  XX,
const Teuchos::Ptr< const Vector >  BB 
) const
inlinevirtual

Solve $ A X = B$ using the given XX and BB (multi)vectors.

This overload of solve uses the given XX and BB (multi)vectors when solving. These XX and BB (multi)vectors are used in place of any X and B that were given upon construction of the Amesos2 solver instance. XX and BB are used only for this solve.

If a permanent change of X and B are required, see the setX() and setB() methods.

Postcondition
  • The (multi)vector XX contains the solution to the system
  • The (multi)vectors X and B given at construction time (if any) are unchanged.
