[Beowulf] Possibly OT

Maybe somebody has a cool beowulf setup for this, but in my opinion this is 
more a task for an LVS (linux virtual server) setup with heartbeat. 

There are two issues you are trying to solve:

One is loadbalancing, can be done with one frontend machine using LVS (linux 
virtual server) to forward web-sessions to one of several webservers. 

The other is high availability so that this one machine going down is being 
replaced by a standby, taking over its IP address. 

Check out www.ultramonkey.org for a lot of good software and documentation to 
the topic.

I just last week set up a two server HA (active/passive) solution for running 
mysql and a customer application connecting to it, using a fibre attached 
nStor for external storage, and it was not too hard. All the information I 
needed I found on ultramonkey.org.
