Re: GMRES/FGMRES and KSP_NORM_NO

Lisandro, No. NORM_NO is suppose to mean that the norm computations are turned OFF. In the gmres algorithms the norm calculation cannot be turned off, therefore setting this flag should generate an error as it currently does. Barry You could perhaps an additional option -ksp_convergence_test <skip,default> if you like that allows turning it off from the command line. On Wed, 29 Aug 2007, Lisandro Dalcin wrote:

GMRES and FGMRES generate an error if the user sets KSP_NORM_NO? Is this really needed?

Curently using option '-ksp_norm_type NO' is handy, as it implies KSPSkipConverged being set.
