Sure. There are issues specific to HPC.

1. Kinds of programs related to HPC: message passing programs,
 HPC libs...
2. Beowulf installation: Inside a beowulf you go mostly for a private
network and don't care about all the security mumbo jumbo. Performance
over everything.
  a. private net
  b. program choices: benchmarks, libs, devel stuff, math...
  c. naming schemes: how do you want it?
3. Tools to do synchronous operations over all nodes. HPC specific stuff:
clean up /scratch partitions, reset daemons, etc.
4. Allocate temporal/spatial subsets of the cluster to certain individuals, 
queue parallel programs to subclusters...
5. Topology matters! People wanna embed nets or optimize for topology, etc.
6.  Virtual clusters make sense... (although for general purpose, too)

Well, of course some of these are bogus, but I think you could make the
list arbitrarily long :) What I mean is that one should think of the 
operational aspects of an actual beowulf cluster.

Starting with a list of machines is just fine. :)
