[Trilinos-Users] Amesos and fill-reducing orderings

I'm wondering about the recommended way to solve tricky linear systems
with Amesos. Mine work pretty well with the MUMPS interface because
MUMPS uses a reordering strategy like metis/pord etc, whereas seemingly
the other solvers don't (?). Should I compute a reordering with some
other package first (isorropia maybe?), what's the easiest interface to
use? I want to put a master student to work on something, but he doesn't
have Trilinos (or even C++) experience, so something not involving Thyra
and the like would be nice.

Thanks a lot,
