Quick note for those reading Ulrich's paper:  he refers in a couple of 
places to Intel's upcoming CSI approach to NUMA.  This has now been 
renamed QuickPath, and it looks like it will be late 2008 before that even 
makes it to Itanium processors.

The fact that AMD has a good NUMA implementation in their Opteron lines 
while Intel's Xeon processors do not is one area AMD still has a clear 
competative lead on.  But you need memory bandwidth starved application 
before that matters more than the fact that the current Xeons are faster 
in general.
