OK, I feel like trying this one (call me stupid if you will).
Thanks for your info, this is very helpful.
So until end 2007 the core2 annihilates any opteron system.
No!!!!!!!!! This may be true for your application, but it's not
true for all applications. I have a couple of applications where
a 2.6 GHz Opteron with beat a 3.0 GHz Woodcrest.
Another example is Fluent, where a 3.0 GHz Woodcrest kills
the Opteron on a single node or a small number of nodes.
But as you increase the number of nodes, the Opteron is faster
than the Woodcrest.
Why is this? Is it the interconnect, PCI-E implementation,
maybe cache effects?
