[ale] Fedora and RHN?

[Dow Hurst]

Linux Format ran an article on a dual opteron server.  It gave 
incredible performance and they loved it.  Was the loudest machine 
they'd ever had.  The fans were like a jet taking off. ;-)

They explained in the article that many apps and the kernel too are 64 
bit enabled already.  So, instead of the operations having to be broken 
down into two 32bit operations you get a single cycle.  I don't know 
enough to comment other than regurgitate the article.

Also, if you look at clustering specs between Xeon duals and Opteron 
duals the Numa enabled Opterons handle RAM differently which can speed 
up performance alot.  Was reading a Fermilab project page on cluster 
specs and found alot of really good info.  Google "Benchmarks" and 
Fermilab and possible MILSPEC and you might find the page.  I don't have 
the URL.
