why PVM?  it's a fine system, but MPI has, practically speaking, obsoleted it.

beowulf is not really a singular thing, but a concept.  there are many
instances which are downloadable and relatively turnkey if you're not 
very picky.  Oscar, Rocks, Perceus/Warewulf, etc.

you should DEFINITELY use the same OS on all nodes.  mixing OSs merely
adds support issues and complexity.

if you simply have a handful of machines, I think you should take 
the lowest-tech approach: install a comfortable distro on all of 
them, and you're done.  distros like fedora already include working 
versions of MPI (indeed sometimes even PVM).  for a personal cluster,
you don't necessarily need anything else: schedulers, monitoring,
private networks, etc.  it's not absolutely necessary, but the first
feature I'd add would be a shared filesystem (just an NFS export from
somewhere).

well, I think there's more to becoming a phd than running sims on a cluster ;)
