multiprocessor SMP support?

Hi Gurus,

I wish to know if launching multiple Erlang nodes would take advantage 
of a SMP server class PC? Will a two processor PC only require two 
nodes? Will Linux automatically assign each node to each available 
processor? Does message passing between these nodes suffer any bandwidth 
impediment compared to message passing between processes within a single 

Am I asking too many questions on a Friday afternoon?

I think it's interesting to be able to combine multi-CPU
support with many thousand processes. One use that comes to
mind would be to separate communication and control (where
there could be thousands of control threads), or control and
Operation and Maintenance, while still running on the same
processor board. Essentially, coarse-grained load sharing
without many of the hassles of distributed computing
(loosely coupled computers on a slow communication medium.)
