No worries and thank you. I just don't quite understand the stuff
returned by 8000001e and what I see above. Do I understand this
correctly that a single CPU has 2 NUMA nodes? Does that mean a single
HW socket consists of two independent 6 core CPUs?
Well, anyway, I just got remote access to a 2 socket systems with
Opteron 6386SE CPUs. It's installing rhel7 right now so I might get
another clue from there.
Thanks,
Corinna
