[petsc-users] KSP solver and Distributed arrays

[Mohamad M. Nasr-Azadani]

Hi guys,

A simple question.
Can I solve a linear system [A]{x} = {b} using KSP solvers using Matrix and
rhs, solution vectors with different number of ghost nodes (width)?
As an example, can it be possible to solve for
vector {x} DA, width=3, STAR stencil,
[A] DA, width=1, STAR stencil
{b} DA, width=1, STAR stencil

I am suspecting that it is not possible.

Thanks,
Mohamad
