The typical chipsets we use around here are not NUMA with Xeons -- all
of main memory is the same distance from all the cpus. It's my
impression that the grouping of cores to sockets and such isn't
part of the NUMA code in the kernel. (Anyone?)
In the future, QPI Xeons will be NUMA, similar to Opterons. There are
also some exotic chipsets that do NUMA with Xeons today, but you
probably don't own one.
