and we subsequently ask the dof_handler object to distribute the degrees of
freedom as follows
dof_handler.distribute_dofs(fe);
can we proceed to renumber the DoFs with Cuthill_McKee and component_wise?
Does this create a bandwidth minimized component_wise renumbered sparsity
structure for each process.
I have this question because when I'm using the serial version of
triangulation, I'm explicitly calling subdomain_wise renumbering first and
then Cuthill-McKee and component_wise renumbering on 4 processes, I can see 4
bandwidth minimized structures which might illustrate that the renumbering
retained the individual partition identity.
Nihar: I believe that this should work. What happens if you try?
