You can use LVS (Linux Virtual Servers) as a load balancer and high
availability clustering technique. It comes already setup on the kernel,
all you need to do is install a package called IPVSADM to be able to
manipulate the cluster. Carlos :-)

Take a look at http://openmosix.sourceforge.net/
That is the open source product of choice since Beowulf, and others,
decided
to start selling the product. Unfortunately, I don't see an S/390 port for
this product so I apologize of being off-topic with this reply.
