int KSPGMRESSetOrthogonalization( KSP ksp,int (*fcn)(KSP,int) )Collective on KSP
ksp | - iterative context obtained from KSPCreate |
fcn | - Orthogonalization function |
KSPGMRESModifiedGramSchmidtOrthogonalization() - default.
KSPGMRESUnmodifiedGramSchmidtOrthogonalization() - NOT recommended; however, for some problems, particularlywhen using parallel distributed vectors, this may besignificantly faster.
KSPGMRESIROrthogonalization() - iterative refinementversion of KSPGMRESUnmodifiedGramSchmidtOrthogonalization(), which may be more numerically stable.
