Dear PETSc team:
For one of my applications, I need to know which owned DAG points in a
(DMPlex) are other ranks' ghosts.
Say, rank-0 has some point "x" (which it owns) and it shows up in, say, rank-1
as a ghost numbered "y".
Then, if I inspect the "Point" PestcSF, in rank-1 there should be a leaf for
"y" that records rank-0 and the value of "x", right?
However, back in rank-0, the same PetscSF has no record that "x" is "y" in
rank-1 (and potentially "z","a","b",... in additional ranks).
Is this what, in PetscSF terminology, is referred to as "One-Sided"?
If so, I think what I am really asking is how can I obtain a "Two-Sided"
version of the PointSF?
