hey fellows and gals, this confuses me to no end.<sigh>

processor : 1 ... siblings : 2 ...

It sure looks like I have 2 processors.

Yes, it does. What's the problem?

What say you?

What's the question?

It's a Pentium 4 that i bought almost 2 years ago and before duo was mentioned. So HOW do I have a Pentium 4 with 2 cpu's?

It's a HyperThreading CPU. A half-hearted shot at a dual-core CPU. In a dual-core CPU there's a 100% complete pairing of all the circuitry that makes up a CPU (though they share the level 2 cache). In a HyperThreading CPU not all of the CPU hardware is present twice, hence there is less available parallelism. I don't know the details, but a plausible example would be that two concurrent integer multiplies could be occurring but two concurrent double-precision floating-point multiplies could not take place.

Peace. Hah! If humans wanted it, they could have it... Hmmm... I'm watching the season premier of "24"...
