In Sierra, we build and solve large parallel dense linear systems using Scalapack.  The interface to Scalapack was developed with lots of help from the Trilinos Developers.
Basically  I recommend that you use Sierra.

I've been looking around in Trilinos for some functionality that allows me to build large parallel dense matrices associated with
Method of Moments (or boundary element methods) and to then invert them.  Has anyone ever done this in Trilinos and if so
what was used?  Most of the functionality in Trilinos targets sparse matrices as far as I can find.
