I'm too tired to do it justice (just back from the 2nd of a 3 day AIX
course), but :-
* It implies that the Origin2000 was one of the first NUMA systems. I
 don't believe it was ... Sequent and similar was far earlier. The
 ccNUMA architecture did address some weaknesses of the NUMA
 architecture.
* The AMD Opteron is a NUMA system ? I suppose it might have on chip
 support for some NUMA architecture, but surely NUMA is more the system
 than just the CPU ?
* It mentions the StarFire as being designed by Cray. Wasn't it just
 the CS6400(?) designed by Cray ? Admittedly the E10K is quite
 different to the other USII Enterprise line.
