biggrin Dual CPU use

laughing Just for what its worth if anyone at UD is tracking I have a dual MP and a couple of P4 hyperthread mechines just loafing. Does the client take advantage of the MMX or 3Dnow technologies in the current Intel and AMD CPUs?

cool Re: Dual CPU use

Surely you are wondering if the application program Rosetta uses these instructions? But about the UD Agent, I have noted the following post on my list of interesting posts:

gbo2 10 Dec 2004 UD Tweaker does NOT work!! Second page of thread.

Apparently the current UD Agent contains an unused buggy attempt to multi-process. I suspect that WCG is contemplating this while developing the Linux X86 Agent. After all, there are many Linux multi-processor servers. Something about the multi-processor license fees for Linux being lower than the Windows fees. [Grin]

Hmm. Just for the record, while of course linux costs less than windoze, there is no additional cost associated with multi-processor versions, at least, not until you get over 4 processors and are into server versions. Desktop Linux is free or cheap, depending on how you get it, and desktop Windows has an associated cost built into the purchase of the computer (usually). But BOTH support multiple processors without any additional licensing costs over the initial (single-processor) purchase.

Our renderfarm, as an example, is all dual-processor Boxx rendernodes running Win2k Pro.

Re: Dual CPU use

Oh, forgot one more thing... Hyperthreading is useless as far as this project is concerned. Won't hurt, but won't help a bit. Please see my post in the thread Lawrence linked to (above) for details on why. Actual dual processor machines help, however... some, for now, and should help considerably once the software gets true SMP capabilities.

We're still waiting for word from the WCG folks on the timeline for the software update, which many of us are eagerly awaiting...

Re: Dual CPU use

Well, i guess you could try to install a second instance in another map. Then you'll have it split up in 2 devices in the statistics. But who cares about that. Anyone tried that before? I think it should work!

cool Re: Dual CPU use

Pconfig, David Autumns was talking about multi-processing in this post: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=767#3418

CompuDude, thanks for correcting me. I had gained the impression that there were multi-processor fees charged on even dual processor machines while reading articles in the Inquirer about the 'no additional charges' decision for multi-core CPUs.

shock Re: Dual CPU use

Hyperthreading is useless?! Say it ain't so! My little CPUs are working themselves to death. I never did get a clear answer, for this newbie, if the UD client is using SSE or MMX or 3DNOW instructions sad

cool Re: Dual CPU use

My personal view (free and worth what it costs) is that hyperthreading works really well for video editing with its' very regular memory structures and is useful for running audio with games (otherwise the frame rate drops if you activate audio). However, I do not think it is particularly helpful for the WCG Agent. I have been wrong about lots of things, though.

Re: Dual CPU use

Ok so it’s still not clear if they will have dual processor support yet? Mean while you can install to instances of the program via creating two profiles in two different directories?

Is this where we at ? If not clear it up for someone who unfortunately is still clueless.


I was curious as well is SSE instructions supported example being the SSE,SSE2, and SSE3? Basically supporting new instructions added in processors.....

Hyper threading I agree it helps in the above areas mentioned, but should not make a difference in WU stuff.

Also I know this post may irritate those who have answered maybe a lot of these questions, but I ask patience sense I truly just don't know.

I was wondering also if they will support MAC and LINUX ?

Also will there be support for current and future 64 bit processing?

I love new Techno, and always curious about future support of it =)

Hey thanks guys/gals.

Re: Dual CPU use

bcarter, yeah that's the way how to do it for now

I don't think it supports SSE or other optimalizations. Rick Alther posted it somewhere but i can't find it anymore!

But i'm still convinced that hypertrading really would give a performance boost if you run 2 threads on it! Look at the seti project, if you run 2 instances you'll notice that you do about 1.4 x your old wu average!
