You can use LAM on a single node with multiple CPU's, and it will run part of the task on each CPU. This is not a Beowulf, of course, but it is quite easy to start running MPI programs on more than one computer once you've got the idea of what MPI is all about - Why not join in the 'easy' Ubuntu clustering thread and tell us how you get on trying out LAM?
sudo aptitude install lam-dev lam-mpidoc
