[Carpet] component geometry for multi-core processor chips

[Steve White]

Erik & al.

Does Carpet do anything regarding clumping together geometrically 
processes that are running on the same node?

If 8 processes are running per node, it makes a very big performance
difference if the 8 on each node are arranged in a cube, because much
less network communication need be done.

We already have low cost clusters with dual-core dual-chip motherboards,
which would benefit, and the quad core chips are soon to come.

Any ideas on this?
