Okay. Here's what I'm trying to do overall:

I have 2 meshes, 1 for Poisson and 1 for Schrodinger. The Poisson mesh is
over a big domain, and Schrodinger mesh lies only in a small region inside
it.

I locate Poisson quadrature points inside Schrodinger mesh, because that's
where I need to evaluate solutions of Schrodinger mesh. Now, since the
Poisson mesh is quite big, all the quadrature points which lie inside
Schrodinger mesh are usually are on a small number of processors.

I need to distribute these points among processors according to the
Schrodinger mesh partitions.

What's the best way to ghost elements and solution vectors in this case?

Thanks!
Harshad
