Re: Question on DA

[Barry Smith <bsmith@xxxxxxxxxxx>]

   The default layouts of "grid points" is independent of the number  
of degree's
of freedom per point so each process will get the same "patch" for  
both DA's.

  If you are worried about the two DA's having some duplicate  
information that
wastes memory (information that could be shared between the two),  
don't; the
amount of excess data is very small relative to everything else in the  
code and
is not worth worrying about.
