HYPRE_Int HYPRE_GMRESSetSkipRealResidualCheck

(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.
