Not quite the same as an HPC cluster, but take
a look at the University of Utah's Emulab:

It is heavily based on FreeBSD (i.e. makes use of FreeBSD routing,
Dummynet, etc.).  The Emulab is a remotely accessible testbed
that researchers can use to conduct network experiments.  It
consists of about 200 PC nodes.  The same company that 
Brooks works for (Aerospace), has apparently set up
an internal testbed based on the Emulab software developed at Utah.

I use the Emulab every day as party of my research work at
BBN, and it is an excellent facility.
