I know Gentoo is Linux and Linux has SMP support. As I stated, I run a dual-933 SMP system presently. But, how in the heck do you pick up 4CPUs with HyperThreading? I thought HT was a memory-specific technology, not CPU? And do you actually see any significant performance gains with your illusion of 4 CPUs?

Okay, okay ... well, like I said ... I run a dual-933 rig right now. I've been doing SMP for quite some time in Gentoo. Pretty proficient with it on a P3 platform. Just curious how things might be different with P4 Xeons. However, since the box here is built with -march=pentium3, docs say that will only work with PentiumIII system. Thus, the docs seem to intimate that Pentium4s will not work. Though, I can see how this could not necessarily be the case. But why wouldn't I want to change over to -march=pentium4 ?? Will this break things or something? Won't the programs be a bit better optimized using pentium4 for arch? Neuros. --***-- Yep, this message is electronic. Zeroes and ones, baby.
