Let me give you some URL's from the first link that pops up from
www.freebsd.org when you do a search on "clustering".  As I understand it,
heartbeat is the server equivalent of Hot-standby Router Protocol whereby
machines send a notification to one another at Layer 2 to show they are
alive (or not if there is no message), letting the other server know it
has to take over the work of the first, down server upon failure.

The following URLs should disprove this;

The Parallel Virtual Machine is nothing more
than a software package that makes setting up a Cluster simple. The source
code is freely available, and will run on FreeBSD without much problem.

In addition to this, Tom Rhodes is currently writing an article designed
to walk a user through setting up a Parallel Computing environment using
FreeBSD and other utilities. Keep an eye out for this article in late 2002
early 2003.
