Hi, I am trying to implement a non-local finite elements reconstruction operator in parallel.
Given a dmplex distributed with an overlap, is there a way to figure out which cells are in the overlap and which are not? Alternatively, suppose that I distribute the same DM with and without an overlap. Is there any warranty that the distributions are compatible (i.e. coincide when the overlap is ignored)? If this is the case, can I assume that the non-overlap cells are numbered first in the overlapped dm?
