As Ashley says, you use DHCP for the network configuration.
There is very little else you should need to configure differently on
each individual host - for instance batch scheduler systems store
information on
batch nodes in a central place. All the node needs to do is be
configured to know its batch master, and to start the batch system
daemon, then
wait for the jobs to come in.
Any changes to (say) /etc/pbs.conf are generally made to all the
cluster nodes identically.
