Folding@home GPU2 Beta Released, Examined

Posted by Zonk on Wed Apr 16, 2008 03:35 PM
from the nice-to-give-my-console-a-hobby dept.
ThinSkin writes "Stanford has recently released an update to their Folding@home GPU-accelerated client, which includes notable upgrades such as support for more current Radeon graphics cards and even a visualizer to see what's going on. ExtremeTech takes a good look at the new Folding@home GPU2 client and interviews Director Dr. Vijay Pande about the project. To the uninitiated, Folding@home is a distributed computing project in which hundreds of thousands of PCs and PS3s devote a portion of their computing power to crunch chunks of biological data. The goal is 'to understand protein folding, misfolding, and related diseases.'"

[+] Games: Folding@Home 2.0 - An Online Protein Folding Game 129 comments
a boy named woo writes "Tired of justifying your gaming addiction? Now you can really help accomplish something while you play... thanks to Howard Hughes Medical Institute researcher David Baker at the University of Washington." In collaboration with others, Baker has designed a game, called "Foldit," with a practical outcome: players manipulate on-screen images of protein chains and attempt to predict their folding patterns. From the article: "'Our main goal was to make sure that anyone could do it, even if they didn't know what biochemistry or protein folding was,' says [co-creator Zoran] Popovic. At the moment, the game only uses proteins whose three-dimensional structures have been solved by researchers. But, says Popovic, 'soon we'll be introducing puzzles for which we don't know the solution.'"

      You shouldn't be joking.

      Folding @ Home on a PS3 costs the average participant around $150-200 year in electricity if they run it 24x7. Up to $400+ in places where electricity is more expensive. PCs average less, but only because so many of them are lower power, while all PS3s are high wattage.

      I think its a worthwhile project, but the electricity people are donating isn't free and F@H uses a lot more electricity than most people think. "Oh, I've got my PC on anyway", or "Oh it can't be as much as my fridge." both of which are mistaken, your fridge uses a fraction of what a PS3 running F@H does, and even if your PC is on, running at idle or going to sleep uses a LOT less power than maxxing out the cpu and/or gpu 24x7.

      A PS3 running @ 280W 24x7 for a year:

      280W x 24h/d x 365d/y = 2452800 Watt-hours/year or 2452 kWh/y

      at $@.12/kWh that'll cost you: $294.00 / year

      Then multiply that by the number of PC's running it... it adds up fast.

      Like I said, its a good program and a good cause, BUT its not free. A kid/teen shouldn't be running it without a parents permission and understanding of the cost.

      I don't like the F@H 'propaganda' because I think its somewhat deceptive about the costs. Its relying on peoples attitude that their free cpu time is truly free to prevent them thinking about the real costs. If you probe they don't lie about the costs, but ethically they really should be more upfront about them.

      And now that there is money involved, I should choose the best use of it. When I'm faced with a decision of choosing the best place to donate $300 I think their are other causes more worthy of my money than F@H. But that's a personal choice. If you want to donate to F@H, by all means do so.

      One final issue - generally when you donate more than $10-20 to charity you get a tax receipt. $150-500 quite a bit more than $10.

          Fair enough. But its a little dishonest if you don't REALIZE how much you are invested. That's my biggest issue. Once people know what it costs I have no issue if they're still willing to contribute. But it bugs me, especially since I beleive the a very significant proportion of the people contributing to F@H are not the one's paying the bills.

          The other part is how much do F@H results actually cost, in aggregate? Is it good value for the science produced? They've consumed between $50 and 100 million in electricity. Could they have made better progress towards their goals if they were given the money directly? At the very least if they built their own super computer and managed the costs directly the waste would be far far less.

          Not only would they be paying industrial rates for electricity instead of residential rates, they'd also be using far less of it because they'd have racks of CPUs not all powering hard drives, and what not needlessly.

          Hell, just take a look at the from their site: (For the purposes of this I've assumed that it costs 'volunteers' on average $10 to run a cpu per month in electricty.)

          190,000 PCs generating 182 TFLOPs. 191k cpus. Total Cost ~1.9M/month. ~$10,494/TFLOP/month
            41,000 PS3 generating 1257 TFLOPs. 41k cpus. Total Cost ~0.4M/month. ~$326/TFLOP/month

          What moron would keep the PCs running?

          A final note about overhead. You lose 10-20% efficiency right off the top with F@H due to the lack a tax receipt. I can donate $250 to a registered charity at the same cost to me as buying $200 worth of electricty due to the taxes. Or conversely when you donate $200 to F@H -you- pay an extra 20-50 in taxes vs had you given the same $200 to a registered charity.

          but if i had to choose, and if i had a choice, i'd rather invest in an @home project.. i find it a lot more intrinsically motivating than knowing i'm keeping a statistic alive that in 10-20 years might start earning their country some money through taxation because he's had his K-6 education.

          Between those two I'm inclined to agree. I tend to mostly donate to small local organizations myself.

          Thanks! You are right.

          There was information when the PS3/F@H launched that consumption was 280-300W, but apparently that was actually around 200-220W so my post above was out by ~$70, and now with the newer lower wattage PS3s the price comes down even more.

          But even at 135W, assuming the same .12c kWh I used in my original post that's ~$150/year. Maybe not a big deal to some, but how many would still sign up if they had to pay $150 to f@h directly instead of having it nickle and dime them daily on their power bill? I suspect the user count would be orders of magnitude lower.

    From the article:

    ET: Whenever someone hears about GPU-accelerated FAH, their first question is why there is no client with support for Nvidia cards. In the past it was said that it had more to do with Nvidia's drivers. Now that the core doesn't use DirectX, couldn't a GPU client use Nvidia's CUDA? Is there any work going on there, and if not, why not? Dr. Pande: We are interested in CUDA and are investigating how well FAH on CUDA would work.
    I am awaiting this with some serious excitement. Getting Folding@home working on Nvidia GPUs would definitely add a lot of computing power into the mix. This is especially true now, as it seems that the current crop of high end GPUs seems to favor Nvidia.

    From the benchmarks I have seen, it seems that there are currently no games that can effectively utilize, for example, 2 9800 GX2s. If Folding@home releases an Nvidia client, those people who have plunked $1000 into graphics cards may finally be able to put them to use!

    From TFA, interestingly this bypasses DirectX and interfaces with the card directly (I guess you'd want to, to throw maths at it instead of vertices)

    However it only runs on R600-based Ati cards right now. It also requires .Net framework. They do say they're "investigating" an nVidia version, but that sounds a while away.

    Interestingly also, it claims to parallelize processing the atoms, so it must use the individual stream processors on the graphics card directly.

    So, here's my thought - before someone sends an email, they contact Folding@Home, identify themselves, say who they want to send an email to, and the contents of the email. F@H gives them a work unit. When they complete it, F@H signs their email. Your email client can filter emails based on how many work units the sender did to send it to you. If someone really wants your attention, they'll process for a day or two. If it's a casual email, one work unit will do. Maybe even a fraction of a work unit.

    That way, if you read spam, at least you know that you contributed to F@H. If you want less spam, you turn up your threshold for how many work units the sender has to do.

          There's a HUGE difference between an idle computers power consumption and ones whose CPU and RAM throughput are being taxed to the limit by a process like folding. The 240 watts I mentioned is just the CPU, northbridge, RAM, and internal heat evacuation. Drives and monitor are completely irrelevant.
