Err, well, the easiest way is to just launch the 3 scripts, 2 on the slave 
and one on the head, in separate matlab sessions.  Matlab is single 
threaded, so each session will use one CPU.  And each session can only use 
the memory of the node it's running on.

There are all sorts of tricks one could play with batch schedulers and/or 
Mosix to make this more automated, but for 2 nodes that's well and truly 
overkill.
