PetscErrorCode DMLocalToLocalEnd(DM dm,Vec g,InsertMode mode,Vec l)
Neighbor-wise Collective on DM and Vec Many br
Input Parameters
Output Parameter
l -the local vector with correct ghost values Many br

Notes
The local vectors used here need not be the same as those Many brobtained from DMCreateLocalVector(), BUT they Many brmust have the same parallel data layout; they could, for example, be Many brobtained with VecDuplicate() from the DM originating vectors. Many br
