It is very interesting. I have a P4 HT 3.2. When I first loaded Linux 10.0 a year or so ago and did my first online update. Those were uncomplicated days when we just had a Suse Watcher no ZEN rubbish or OpenSuse Updater that appears when it want to - (sorry for the dig) anyway update download Kernel support for multiprocessors and my assumption is that even though HT is logical the Kernel addresses the single processor as 2. MS-Windows does the same. I can change the affinity for a very hungry application that does not deserve all the attention to 1 (logical) processor without issue.

Daft question:
if you had a CPU with HT enabled doing a cat /proc/cpuinfo showed 2 CPU's.
I've just installed OS10.2 on a dual-core Athlon 64 system but I'm only showing 2 CPU's instead of 4.
I've not used these CPU's before so want to check that the 2.6.18.xxx kernel still shows HT as a separate processor before I suspect the hardware.
Cheers
