const Teuchos::RCP< Teuchos::ParameterList > &  pl 
)

Basic constructor for GCRODRSolMgr.

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

ReturnType Belos::GCRODRSolMgr< ScalarType, MV, OP >::solve (  )  [virtual]

This method performs possibly repeated calls to the underlying linear solver'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 GCRODRIter::iterate(), which will return either because a specially constructed status test evaluates to Passed or an exception is thrown.

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

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

Dimension of current recycled subspace, if one exists.
