Hi All,

What would be the subj? Suppose you have a PC. It can have Intel or AMD
CPUs. It can have HyperThreading on, and even enabled. And it can have one
or two, or several sockets.

Would there be a universal method to count real physical cores? Say,
passing /proc/cpuinfo through a magic filter, and not failing on AMD
Opterons too?
