[petsc-users] gmres restart

[Verena Kuhlemann]

Hello,

I have a (hopefully) quick question about setting the restart for gmres.

I set the restart to be 50, but when I use KSPView it looks like GMRES
still uses a restart of 30. It is possible that I overwrite my settings
somehow? Here is the relevant part of my code:

KSPCreate(PETSC_COMM_WORLD,&ksp);
KSPSetOperators(ksp,A,A,DIFFERENT_NONZERO_PATTERN);
KSPGMRESSetRestart(ksp,50);
KSPSetInitialGuessNonzero(ksp,PETSC_TRUE);
KSPSetTolerances(ksp,1.e-12,1.e-12,PETSC_DEFAULT,100000);
KSPSetUp(ksp);
KSPGetPC(ksp,&pc);
PCSetType(pc,PCNONE);
KSPView(ksp,PETSC_VIEWER_STDOUT_WORLD);
KSPSolve(ksp,b,x);


Thanks,
Verena
