[Beowulf] OS for 64 bit AMD

I second Joe's comments.

All of our Opteron systems run Suse 9.2 by default and we use Centos-4 
for "Redhat" compatible functionality when required since Redhat has 
explicitly chosen to price themselves out of the cluster market for 
everything except 2-way 32bit boxes.

Suse 9.1/9.2 on Opteron and Suse Enterprise Linux (SLES 8/9) on Itanium 
Systems (meaning our SGI Altix) have been extremely stable and useful in 
our work. Highly recommended.
