Solaris Heirarchal Latency Groups for NUMA

Sun has prepared some very tunable parameters to take minute advantage
of AMD Opterons' low-latency NUMA implementation. Looks like Solaris is
designed heavily around taking advantage of Opteron.

Looks much like what other OSes do with NUMA systems. Looks like you
got misled by a press release.

Might be similar to what others are doing in their OSes too, but it
wasn't a press release, it was an actual writeup. However, it looks
like it's offline right now.

We can disagree about that one -- many "technical writeups" on the web
are actually rehashed press releases.
