What's your take of Hyperthreading?

I think many of the above examples are not for me, but then again my system only needs little more then 2 hours to encode a 2 hour divx 5.05pro codec movie with 2 pass, high bitrate 2 cd rip, with 224kbit mp3 audio!!!

Sometimes it more about that sudden use I need the system for and not want to take the hit on my encoding time...It would be nice to know it wouldn't slow it down nearly as much....

I don't see why many can't see the uses....I don'twant a machine I am afraid of touching as it runs a program cause I am afraid it will crash or corrupt the data...like Wingz said, that sounds like there was problems to begin with....

Duvie, there are plenty of programs that I'm not afraid to run together. I could spew a list of about a dozen things that I've run concurrently here at work alongside a full-blown virus scan My point was that games are not usually paragons of stability. Name your top five favorite games from last year. Now tell me how many of these five never needed a patch for any reason.

~ ah so...

night201, to answer your question, the 36-hour render sessions were an 1800-frame animation of a panther walking in fog. I built it from scratch in Caligari trueSpace 4.3 and animated a quadriped walk cycle for it, no mean feat in trueSpace 4.3, which has only one IK nail to offer That was on a dual-P3 733 equipped with 896Mb of PC133, and it still hit the swap file for another ~900Mb because it ran out of RAM. Obviously in this situation I need the RAM freed up for rendering, another reason why it would be foolhardy to run a game alongside the render session. I'd love to try a better 3D modelling/animation app, but I don't go out and "obtain" software the easy way, and I don't have the money to plunk down for 3DSMax or Lightwave.

Duvie probably remembers this trueSpace scene, since I sent it to him to do some benchmarking with on his P4 system using a demo version of trueSpace 4.3

I couldn't have said it better myself. On my kids machine (soon to be a P4) when they go to play a game it slows way down if I have a DC client running. So often times I find them on one of my boxes playing their games.

could i get further clarification:

I do distributed computing clients (Seventeen or bust ) right now. i think that doing a distributed computing client (be it medical, scientific, monetary, etc) is a great way to use spare cpu resources...now onto HT.

Would it be better to run a DC client on a say 3.0ghz p4C or to run 2 instances of the client on a 3.0 p4C...does it not equate into the same thing considering that a DC client uses up 100% of a computers spare resources?
So, basciallyt w/ HT enabled when i fire up a DC client will it automatically only use 50% of the computer's resources thereby forcing me to go the route of 2 instances? I multi-task a lot but nothing where the client cannot slow down for a bit and give up it's resources.

i am just slightly confused as to which would be more beneficial for a box that runs DC 24/7

So far, owners of HT Pentium4's get best results running two separate instances of SETI@Home, definitely, and I'd bet other DC projects will be likewise. Your cooling pretty good...? It's going to get a real workout. One guy was having shutdowns when running two instances of S@H on his P4 (3.0C I think it was). Strange that it couldn't throttle its way out of that.

HT doesnt work in almost anything sides WInXp? Haha. As i said, its all about marketing. *Slaps "Giga-Transition by AMD" on his case*...I feel like Intel customer now!

How can you rationally say "its all about marketing", when there are benchmarks out there proving the benefits of HT?

Are you that much of an AMD zealot that you close your eyes to the facts?

As for your AMD vs P3 comparison, that's about as relevant as if I were to bash AMD since my K6-2 couldn't keep up with my friend's Celeron in ANY game.

Naw, i dont really give a fvck about what cpu i got. The thing is, it is marketing. I've looked at benchies, and apparently only those [sponsored by Intel] are optimized. But the thing is - i dont use ANY of those programs, so HT is marketing

I run 2 instances of Folding@Home on my 2.4C. The temps went up by 2C. I average about 1.5wu's running 2 instances over 1wu running one instance.

Squid... HT doesn't only help out in apps that are multithreaded. It also helps out when multitasking. HT has REAL benefits, thus is is not just "marketing". If you are happy with what you have, more power to you!

Ok, I rummaged up this one by editing a URL: http://support.intel.com/support/platform/ht/os.htm

The following desktop operating systems are not recommended for use with Hyper-Threading Technology. If you are using one of the following desktop operating systems, it is advised that you should disable Hyper-Threading Technology in the system BIOS Setup program:

Microsoft Windows 2000 (all versions)
Microsoft Windows NT* 4.0
Microsoft Windows Me
Microsoft Windows 98
Microsoft Windows 98 SE

So HT is not recommended for Win2000, not even Win2000 Server? Why not? We aren't going to migrate off Win2000 where I work until 2006-2007ish, last I heard.

Well it may not be recommended (Optimized) to run HT but I have two systems running Win2K Pro that are crunching 17-21 Seti wu's a day depending on the AR size. I am not about to disable Hyper-Threading in these.
Win2K Pro 1 = P4P800/2.8C/TwinMos PC3700(2X512)
Win2K Pro 2 = IS7-E/2.4C/HyperX PC3500(2X256)

Edit: I do also get the same Seti WU performance in my main rig (P4C800/2.6C/HyperX PC3500 2X512 with WinXP-Pro) and all three of these are running 24/7 two instances using Seti Driver.
