Jack,
I apologize, I was too quick to dismiss elemental. We went to the effort
to do the MPIDENSE interface for PLAPACK and that ended up being a complete
waste and left a bad taste in my mouth since I consider that wasted time when
we could have done something else.
So we could try again with Elemental but its a question of having a
competent person to do the interface efficiently. Perhaps you have a student or
someone you know that knows elemental we could hire for a short time to do an
interface and see how it goes?
