(HYPRE_Solver solver,
HYPRE_Int skip_real_r_check)
(Optional) By default, hypre checks for convergence by evaluating the actual residual before returnig from GMRES (with restart if the true residual does not indicate convergence).
Documentation
(Optional) By default, hypre checks for convergence by evaluating the actual
residual before returnig from GMRES (with restart if the true residual does
not indicate convergence). This option allows users to skip the evaluation
and the check of the actual residual for badly conditioned problems where
restart is not expected to be beneficial.
