And in the case of dirichlet or neumann bcs, the extremum cell add
information to the RHS, they do not appear in the matrix formulation.
Hope I was clear enough,
thanks

Hi,
I am trying to change my problem to using periodic boundary conditions.
However, when I use DMDASetUniformCoordinates on the DA, the spacing
changes.
This is due to an additional point e.g. in dm/impls/da/gr1.c
else if (dim == 2) {
if (bx == DM_BOUNDARY_PERIODIC) hx = (xmax-xmin)/(M);
Re,
Makes sense to read the documentation, I will try with another
preconditioners.
Thanks for the support.

Hi,
I built petsc 3.7.1 and petsc4py 3.7.0 (with openmpi 1.10.2) and ran the
examples in the demo directory.
$ python test_mat_ksp.py
=> runs as expected (serial)
$ mpiexec -np 2 python test_mat_ksp.py
=> fails with the following output:
Traceback (most recent call last):
