# KSP_NORM_NONE

Do not compute a norm during the Krylov process. This will possibly save some computation but means the convergence test cannot be based on a norm of a residual etc. Many br

Note: Some Krylov methods need to compute a residual norm (such as GMRES) and then this option is ignored Many br
