[ale] Suggestions for 64 bit dual Opteron motherboards

[Dow Hurst]

I've been looking at performance of Opterons vs Itaniums/Xeons.  The more 
Opterons on the motherboard the better.  So, 4P and 8P boards are out there 
now.  Microway or Aspen have 4P units.  A Russian company has created the 8P 
unit.  The Intel stuff is limited on interprocessor communication by a single 
pipe while the Opterons have a switch like interconnect with much higher 
bandwidth.  The Xeon's top out and get starved by the limited pipe they have 
to talk thru.  It is a long term problem Intel has gotten around for now by 
bumping up CPU GHz.

So you get a real increase in performance on the right kind of code on a 4P+ 
motherboard. ;-)

I know your not after that info.  I just wanted to blab about what I've been 
researching....
