Fucking Intel Quad Xeon Hyperthreading

Hyperthreading in the motherfucking hiz-ouse... This thing is chewing comparably-expensive sparc's in side-by-side compiles on postgres, apache, php, etc.

Hyperthreading gives you two virtual CPU's for each actual chip. Xeon only.

Oh hell yes. I nearly wet myself.

uh... any cpu doing nothing will idle... duh....


also, hyperthreading is available in regular P4 starting at 3.06ghz


performance boost in most applications (that support SMP) is 10-15%. really impressive if you ask me!

And only a very small percent of the GFY population will have any clue what you are talking about. Take this wet dream to a tech board.

asuana, i wish this was my machine, it's a customers. but fun to cowpile shit on. i'm all about make -j8

guild, i know they'd be idle, just that fact there is eight goddamn cpu's! i'm use to getting dualies or maybe a quad.

I didn't know the P4's were doing it, but it makes sense. Anyone running P4 SMP with hyperthreading? Dual or Quad?

My last four servers were dual AMD, looks like I'll be going back to Intel.

Oh boy, it can serve files faster! Call me when they improve disk drive technology to the point where it catches up with processors, because my 3GHz box isn't much faster than my 1.6GHz box.

heheh

I've got a hyperthreading capable motherboard but I wimped out and never bothered to get one of the processors that supports it.

No point for me, just a waste of cash. No software I use even supports hyperthreading yet that I'm aware of. Plus my 2.53 Ghz runs everything well so far.

Interlude, short of solid-state disks (which is becoming somewhat common), LVD 320 RAID1+0 with 15,000 RPM drives is about as smokin' as storage gets.

8GB PCI cards are available, and for stuff like mail spools that works pretty well.

P4 does not do SMP at all, that capability is reserved for the Xeon family (which are built on a P4 core, but are in the 603 pin packaging instead of the 478 pin)... P4's w/ hyperthreading enabled do not constitute SMP operation. hyperthreading doesn't benefit most of the tasks people here perform on PC's... video encoding, gaming, won't garner any benefit from hyperthreading, but things like chewing through large flat database's, working w/ huge datasets for molecular modelling, that is where hyperthreading really starts to add some benefit. fire up Mathematica or Reveal on a hyperthread-enabled machine, and you'll see the technology start to shine..

For a server, hyperthreading is ideal, now more apache children can run concurrently. And shouldn't things like burning a CD while still using the machine get a lot smoother for desktop users with hyperthreading?

b.

well, thats just the thing... hyperthreading just isn't the same as real SMP... only certain kinds of tasks get much benefit from it, and some benchmarks have shown an actual performance drop w/ hyperthreading enabled. while it may look really cool to have so many CPU's showing in the task manager, hyperthreading isn't appropriate except in certain situations. head over to 2CPU.com for a lot of information and a very active forum for these topics..

Where can I purchase this?

I'm too lazy to look.

XFR will lease you a hyper-threaded Dual XEON 2.4. Ghz. e-mail tanker@ xfrnetworks dot com.

This one is hard at work!

CPU0 states: 2.0% user, 22.0% system, 0.0% nice, 74.0% idle
CPU1 states: 11.0% user, 17.0% system, 9.0% nice, 70.0% idle
CPU2 states: 3.0% user, 21.0% system, 1.0% nice, 74.0% idle
CPU3 states: 2.0% user, 18.0% system, 0.1% nice, 78.0% idle

Hmmm... yeah... I was planning to do some molecular modeling this week. I'll check this out some more. Thanks.

Just got a dual 2.4 xeon system from dell today.. Very fast!

I am running 4 Dual Xeon Hyperthreading rigs :glugglug
