Thanks. I had another question about the DM and SNES and TS. There are
similar routines to assign the residual and jacobian evaluation to both
objects. For the SNES case are:
DMSNESSetFunctionLocal
DMSNESSetJacobianLocal
What are the differences of these with:

That means that if we call SNESSetFunction() we don't build the residual
vector in parallel? In the pflow example (

Why not? Wouldn't we have a row of zeros except for the diagonal term?
The column that corresponds to that degree of from doesn't have to be
zero, right?
