so ia64 is one of those archs with a ram layout with huge holes in the
middle of the ram of the nodes? I'd be curious to know what's the
hardware advantage of designing the ram layout in such a way, compared
to all other numa archs that I deal with. Also if you know other archs
with huge holes in the middle of the ram of the nodes I'd be curious to
know about them too. thanks for the interesting info!
