[slurm-users] changing the operational network in slurm setup

[Paul Edmon]

We do this for our Infiniband set up.  What we do is that we populate 
/etc/hosts with the hostname mapped to the IP we want Slurm to use.  
This way you get IP traffic traversing the address you want between 
nodes while not having to mess with DNS.
