I'm not a big fan of MPI myself, which is why we've got it wrapped

Hi John, I pasted a somewhat smaller version of my code below. By playing
with the refinement steps limit and the commented out init() and reinit()

Correct.

Correct.

Aperture meaning the jump in values between the solutio
Ok, I see Roy's point.
Let's start over.
I have a DG system (duplicated DOFs).
I calculate the aperture at the DOFs sharing coordinates
(position_at_the_element _minus_ position_at_the_neighbor).
I do that for all integration points.
I need an ordered vector with the bigger apertures first, and I

We're pretty far into XY Problem territory at this point.

What you've said about your vector is that you'll need to be able to
do a maxloc() on it, that

I definitely suggest _not_ copy/pasting code!

Should I copy-paste code from NumericVector to build mine?
Any suggestion?
Another alternative is to sync the solution vector to all processors so
that everybody can do the same calculation.
Seems a little inefficient, but is simple-and-easy.
