I am working on extracting the CPU & memory topology on AMD Opteron
machines. For Athlon64 X2 (dual-core) there is nothing for FreeBSD to do
differently than today.
Once I have the ability to nicely express the topology on an Opteron
system, there are two heavy hitters that have said they will consume the
bits and work on optimizing FreeBSD for Opteron systems.
For Intel dual-core HTT systems, there aren't any NUMA characteristics
I'm aware of.
