Constructors/Destructor | |
RCGSolMgr () | |
Empty constructor for RCGSolMgr. This constructor takes no arguments and sets the default values for the solver. The linear problem must be passed in using setProblem() before solve() is called on this object. The solver values can be changed using setParameters(). More... | |

Return whether a loss of accuracy was detected by this solver during the most current solve. More... | |
Set methods | |
void | setProblem (const Teuchos::RCP< LinearProblem< ScalarType, MV, OP > > &problem) override |
Set the linear problem that needs to be solved. More... | |
void | setParameters (const Teuchos::RCP< Teuchos::ParameterList > ¶ms) override |
Set the parameters the solver manager should use to solve the linear problem. More... | |
Reset method | |
void | reset (const ResetType type) override |
Performs a reset of the solver manager specified by the ResetType . This informs the solver manager that the solver should prepare for the next call to solve by resetting certain elements of the iterative solver strategy. Belos::Problem forces a call to setProblem on the linear problem, and Belos::RecycleSubspace causes the solver manager to "forget" the recycle space generated by previous calls to the solver. In the latter case, the next call to solve() will act as if the solver has never been called before. More... | |
Solver application methods | |
ReturnType | solve () override |
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. More... | |

) |
Basic constructor for RCGSolMgr.
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:
int
specifying length of a cycle (and thus number of max number of search vectors kept). Default: 25int
specifying the number of vectors selected for recycling. Default: 3int
specifying the maximum number of iterations the underlying solver is allowed to perform. Default: 1000MagnitudeType
specifying the level that residual norms must reach to decide convergence. Default: 1e-8.int
specifying how often convergence information should be outputted. Default: -1 (never)bool
specifying whether that only the maximum relative residual norm is printed if convergence information is printed. Default: falsestd::string
to use as a prefix for the timer labels. Default: "Belos" Definition at line 489 of file BelosRCGSolMgr.hpp.

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 RCGIter::iterate(), which will return either because a specially constructed status test evaluates to Passed or an std::exception is thrown.
A return from RCGIter::iterate() signifies one of the following scenarios:
