Hi all,
Per my understanding, the "processor" in "SMP" and "UP" should be a "logic CPU", not a "physical CPU". If the "physical CPU" contains 2 "cores", and every "core" contains 2 "hardware threads", then the "processor" should stands for "hardware thread".
Is my understanding right? Thanks very much in advance!
Yes, you are absolutely right, when speaking from a software point of view. Each logical processor shows up as a CPU in Linux. Of course, if you were to talk to somebody installing physical CPUs in systems, you would get a different answer :) -- All rights reversed.
