Dual processor working? Slackware 12


Hi I was reading this website

http://www.telematica.polito.it/fiore/d620/

and it mentioned that the dual prcessor in dell d620 is not correctly recognized in slackware. Is this still true to slackware 12.2.0?

I ask this because the touchpad issue is certainly true.

The following command will tell you how Linux sees the CPUs.
Code:
cat /proc/cpuinfo
If Linux sees two processors then you will see two descriptions.

Hmm I have an older HT Pentium (physically one CPU) but it also lists in cpuinfo as "CPU 0" and "CPU 1" ...

I ran the same command on my kubuntu and it came out with the same result so I'm guessing it does recognise two cores.

That's because there are two cores here too, but they are virtual not real. HT / Hyperthreading generates two virtual cores for every real core to help with multitasking. It doesn't really help overall performance but does help a lot with multitasking.
