Folding@Home Releases GPU Client
SB_SamuraiSam writes, "Today the Folding@Home Group at Stanford University released a client (download here) that allows participants to fold on their ATI 19xx series R580-core graphics cards. AnandTech reports, 'With help from ATI, the Folding@Home team has created a version of their client that can utilize ATI's X19xx GPUs with very impressive results. While we do not have the client in our hands quite yet, as it will not be released until Monday, the Folding@Home team is saying that the GPU-accelerated client is 20 to 40 times faster than their clients just using the CPU.'"
Anybody got an idea of what kind of power constant full speed GPU calculations are likely to burn?
You wont damage your card. The GPU's cooling system is rated for keeping the GPU within its thermal design spec at full load, how long you run it doesnt matter as long as there is adequate ventilation. That applies to gaming too, so its not a problem. As to sppeding up its death, your card will become obsolete by the time that happens.
I agree. We should stop all science not having a direct impact on cancer until cancer is cured.

"With help from ATI, the Folding@Home team has created a version of their client that can utilize ATI's X19xx GPUs with very impressive results."
And therein lies the rub. While GPU's are getting more and more like general purpose vector floating point units, they remain closed architectures, unlike CPUs. Only those that can get help from ATI (or Nvidia) need apply to this game.
Not all the power gets dissipated as heat. Some gets sent down the Internet tubes.

Two problems:
1) There is no Linux GPU client (yet)
2) Many gamers who use Linux have gone nVidia due to driver support. There is no nVidia client (yet)

Most of the distributed-computation projects have a very simple communication model - use HTTP to download a chunk of numbers that need crunching, crunch on them for a long time, and use HTTP (PUT or equivalent) to upload the results for that chunk, etc. Works fine through a corporate firewall, and the only significant tracking it's doing is to keep track of the chunks you've worked on for speed/reliability predictions and for the social-network team karma that helps attract participants.
Online games normally have a much more complex communications model - you've got real-time issues, they often want their own holes punched in firewalls, there's user-to-user communication, some of which may involve arbitrary file transfer, and many of the games are effectively a peer-to-peer application server as opposed to the simple client-server model that distributed-computation runs. Fortunately, gamers would never use third-party add-on software to hack their game performance, or share audited-for-malware-safety programs with their buddies, or "share" malware with their rivals, or run DOS or DDOS attacks against other gamers that pissed them off for some reason.....
As far as the effects of running a CPU or GPU at high utilization go, most big problems will show up as temperature, though there may be some subtle effects like RAM-hogging number-crunchers causing your system to page out to disk more often. Not usually a big worry if you're running a temperature monitor to make sure your machine doesn't overheat. Laptop batteries are an entirely separate problem - you really really don't want to be running this sort of application on a laptop on battery power. I used to run the Great Internet Mersenne Prime Search when I was commuting by train, and not only did it suck down battery, the extra discharge/recharge cycles really beat up a couple of rounds of NiMH battery packs. Oh - you're also contributing to Global Warming and to the Heat Death of the Universe. But finding cures for major diseases is certainly a reasonable tradeoff, and we'll do that faster if you're using your GPU as opposed to 10 people using general-purpose CPUs.

Is there any way I can use this to make my next graphics card purchase tax deductable?
They're studying the folds of protiens. All protiens are made of chains of amino acids, but usually more than one chain, and they're folded and twisted in a precise way in order to perform their functions. Think of them as a cell's nanomachines. Some of them are so large and complicated that it takes quite a bit of CPU power to calculate how they will fold.
You make a very good point.
A computer that does some task today, should -- assuming it wasn't designed to be flawed or have a fixed life expectancy from the very beginning -- still be capable of doing that task in ten years. And for the most part I think this is true; it will.
Most computers that are 10 years old still run fine today (ones that were well-made in the first place); the problem is more one of finding a purpose for them, and then finding software to run on them, then getting them to start. Actually, I would wager that lots of computers that are 20+ years old would still run fine today, depending on how they've been stored and taken care of in the interim.
The problem isn't that machines really "wear out" all that quickly; with some exceptions few do. It's more the relentless drive of increasing expectations that puts working equipment in the landfill. At least for home users; commercial users have their support contracts to worry about, so it's slightly more complicated.
Case in point: I have an Apple IIc in my closet right now, which I know for a fact works fine. I could take it out tomorrow, set it on my desk, put in Apple Write, fire it up and start typing away. Somewhere around I even have a dot-matrix serial printer that I could use to output from it. Everything that Apple advertised that computer as capable of doing, it is just as capable of doing today as it was twenty-one years ago. So why am I not using it? Why am I sitting here with a computer that's only four years old, when I have a perfectly functional computer from 1984 in my closet? It's not because I like spending money. It's because I want to do things that I can't do on an old computer. There are a lot of things that I consider necessities, or at least things that are nice enough to have that I'm willing to pay for them, that weren't possible or even considered more than a few years ago.
If you honestly think that what you can do with a computer today is all you're ever going to want to do -- that you won't see some neat feature on your friend's box in 2014 and decide that you need to have it -- then you're absolutely correct; the computer you have now is the last one you ought to ever have to buy. Realistically though, most people aren't like this; they know that the computer they have today isn't going to be something they're going to want in five or ten years, and they're not willing to pay for a machine that's built to last longer than that.
The things that people use home computers for has changed, and will continue to change, and the tasks that people want to use their computers for will drive the upgrade cycle far faster than the breakdown rate of the components does.

I predict that this new client that runs on ATI hardware will cause a spike in sales of their products. I, for one, will be trying to get this card for my computer so that I can improve the rate that folding@home runs on my system. And I'm certain that others have the same intention.
If you think about that, it says something about us that I think is important; people want to help and they're willing to spend their money to be helpful.
The concept of voluntary grid computing is a curious one. Why do people do this? Surely one more little CPU grinding away at a huge problem won't make a difference. Yet even though we all know this, we do it anyway. The result of this collective hopefulness and helpfulness is tangible. But what else is strange is that so little notice is given to grid computing. I don't recall hearing about it on CNN or any other news television program. SETI gets air time because it's so, well, 'out there', but the folding, aids, cancer/find-a-drug stuff is operating in obscurity.
BTW, kudos to Slashdot for helping get the word out. I first heard about grid computing here.
Best regards.
