Detailed Description

The BatchSolver is a base class for all batched solvers and provides the common getters and setter for these batched solver classes.

Member Function Documentation

get_max_iterations()

reset_max_iterations()

void gko::batch::solver::BatchSolver::reset_max_iterations ( int  max_iterations )

inline

reset_tolerance()

void gko::batch::solver::BatchSolver::reset_tolerance ( double  res_tol )

inline

Update the residual tolerance to be used by the solver.

Parameters

res_tol

The residual tolerance to be used for subsequent invocations of the solver.

reset_tolerance_type()

void gko::batch::solver::BatchSolver::reset_tolerance_type ( ::gko::batch::stop::tolerance_type  tol_type )

inline

Set the type of tolerance check to use inside the solver

Parameters

tol_type

The tolerance type.
