[Beowulf] OS for 64 bit AMD

[Joe Landman]

Hi Mike:

   Opterons will do better with a 2.6 kernel (2.6.9 and higher).  If you 
are going to use RHEL, you might want to look at Rocks (RHEL3 based) or 
Warewulf which should be able to sit atop RHEL4.  If you want to use a 
Redhat work-alike, you might want to look closely at Centos4.

   I am sure others will take issue with this, but I would strongly 
advise against using a rolling beta OS (FC-x) as the basis for a 
production cycle machine.  If it is a purely experimental cluster, go 
for it.  If it is supposed to provide cycles to a wide group, you might 
look more closely at a supported/supportable distribution.

   We have had good luck with SuSE 9.x (x>=1), RHEL3, CentosX on 
clusters using a variety of meta-distributions (warewulf, Rocks, 
others).  Most of our customers seem to prefer the RHEL series, so we 
tend to work with that more than others, but YMMV.
