#undef __FUNCT__ #define __FUNCT__ "KSPGMRESClassicalGramSchmidtOrthogonalization" PetscErrorCode KSPGMRESClassicalGramSchmidtOrthogonalization(KSP ksp,PetscInt it)Collective on KSP Many br
ksp | - KSP object, must be associated with GMRES, FGMRES, or LGMRES Krylov method Many br | |
its | - one less then the current GMRES restart iteration, i.e. the size of the Krylov space Many br |
-ksp_gmres_classicalgramschmidt | - Activates KSPGMRESClassicalGramSchmidtOrthogonalization() Many br | |
-ksp_gmres_cgs_refinement_type <refine_never,refine_ifneeded,refine_always> | - determine if iterative refinement is Many brused to increase the stability of the classical Gram-Schmidt orthogonalization. Many br |
Notes: Use KSPGMRESSetCGSRefinementType() to determine if iterative refinement is to be used Many br
