DUAL CORE CPU

Hi All!

Sorry for this question, but can somebody explain to me what is the meaning of DUAL CORE CPU. Let´s say if I type ioscan -fnC processor, if see 4 CPUs does it mean that its actually 4 CPU´s or 2?
Sorry if I upset you guys

Re: DUAL CORE CPU

A dual core CPU has two cores, in one socket.
So you have 4 CPUs and two sockets.
(This is ignoring hyperthreading.)

What type of hardware do you have? What HP-UX version?

Re: DUAL CORE CPU

Based on this information, you cannot tell.

A dual core has 2 CPUs on a single chip (in a single socket), a quad core has 4.

If possible, run "machinfo".

Hope this helps!
