Well, communication between the two nodes _will_ be faster if they run
on the same SMP box.

It depends on what other Linux processes the system is running.
If you want to be sure, run a recent kernel with "CPU affinity"
support. Then you can bind those nodes to different CPUs.
You'll need a 2.4.18 or newer redhat kernel, a 2.4.21 or newer
standard kernel, or a current 2.5 development kernel for this.
(Other vendors may have it too, I wouldn't know.)
