Something like
DMDASetComputeGhostBoundary(DM dm, s(DM,Vec,Vec,void*),d(void*))
where
s(DM dm, Vec g, Vec l, void*ctx) {
User code that fills in appropriate places in l.
d(void* ctx) {
Optional: Destroys optional user context when DM is destroyed.
}
and s() gets called inside of DMGl

Dear petsc developers and users,
I am a new petsc user ^_^.
I have some questions about using DMDA_BOUNDARY_GHOSTED.
1. I have 2D Poisson code with domain (nx, ny), and I used
DMDA_BOUNDARY_NONE, then the size of the matrix is (nx*ny)X(nx*ny). *what
is the size of the matrix if I used DMDA_BOUND
