Re: Whining about NUMA. :) [Was whining about 2.5...]

Just to put in my $0.02 on this... Compaq systems will span the range
on this. The current Wildfire^WGS Series systems have two levels -
either "local" or "remote", which is just under 3:1 latency vs. local.
This is all public knowledge, if you care to dig through all the docs. ;)

With the new EV7 systems coming out soon (next year?) every CPU has a
switch and memory controller built in, so as you add CPUs (up to 64) you
potentially add levels of latency. I can't say what they are, but the
numbers I've been given so far are _much_ better than that. Just
another data point. :)
