Detailed Description

template<class ScalarType, class MV, class OP>
class Anasazi::BlockDavidsonSolMgr< ScalarType, MV, OP >

The Anasazi::BlockDavidsonSolMgr provides a powerful and fully-featured solver manager over the BlockDavidson eigensolver.

This solver manager implements a hard-locking mechanism, whereby eigenpairs designated to be locked are moved from the eigensolver and placed in auxiliary storage. The eigensolver is then restarted and continues to iterate, always orthogonal to the locked eigenvectors.

Anasazi::BlockDavidsonSolMgr< ScalarType, MV, OP >::BlockDavidsonSolMgr ( const Teuchos::RCP< Eigenproblem< ScalarType, MV, OP > > &  problem,
Teuchos::ParameterList pl 
)

Basic constructor for BlockDavidsonSolMgr.

This constructor accepts the Eigenproblem to be solved in addition to a parameter list of options for the solver manager. These options include the following:

Member Function Documentation

template<class ScalarType, class MV, class OP>
ReturnType Anasazi::BlockDavidsonSolMgr< ScalarType, MV, OP >::solve (  )  [virtual]

This method performs possibly repeated calls to the underlying eigensolver's iterate() routine until the problem has been solved (as decided by the solver manager) or the solver manager decides to quit.

This method calls BlockDavidson::iterate(), which will return either because a specially constructed status test evaluates to Passed or an exception is thrown.

A return from BlockDavidson::iterate() signifies one of the following scenarios:

Returns:
ReturnType specifying:
  • Converged: the eigenproblem was solved to the specification required by the solver manager.
  • Unconverged: the eigenproblem was not solved to the specification desired by the solver manager.

Implements Anasazi::SolverManager< ScalarType, MV, OP >.
