The Linux folks often refer to an implementation called Beowulf: http://en.wikipedia.org/wiki/Beowulf_%28computing%29 I was also able to find these, more specific to the BSDs: http://www.freebsd.org/advocacy/myths.html#clustering http://lists.freebsd.org/pipermail/freebsd-cluster/2006-June/000292.html http://people.freebsd.org/~brooks/papers/bsdcon2003/fbsdcluster/ -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
