[petsc-users] Gauss-Seidel

Dear Petsc team,

I would like to do 10 iterations of a point-by-point Gauss-Seidel 
procedure for the purpose of testing.

Is it correct if I type "mpiexec -n 1 ... -ksp_type preonly -pc_type 
sor -pc_sor_its 10"?

How can I define the initial guess nonzero?

Best regards,

Kathrin
