) A: k" U' S- d! A' I" |" ^, N' WIntel engineer Phil Kerly explains how to detect both Hyper-Threading Technology-enabled processors and multi-core processors. More importantly, he presents how to associate which multi-core processors share the same physical processor package as well as how to associate which Hyper-Threading Technology logical processors with which core.
