If this is a personal cluster, and you are going to be the only user,
installing cluster management software would probably be not
worthwhile. If you make sure you install the same software in all the
nodes, connect them with a switch, perhaps install NFS for your home
directory and install a version of MPICH, you probably have all you
need for many happy hours of parallel computation.
