Posted on 11/21/2006 8:07:23 PM PST by texas booster
Today ATI's graphics processors help accelerate complex computations in stream computing applications used in scientific research. ATI is supporting bio-medical research to help scientists understand disease at the genetic level. With a strong understanding of how diseases form, it will become possible to develop diagnostic methods, and preventative treatment and medicine for many acute diseases in humans.
Stanford University is using ATI’s GPUs (Graphics Processor Units) to run Folding@Home, a distributed computing project designed by its chemistry department. This application performs computationally intensive simulations of protein folding, using the stream computing capabilities of ATI’s Radeon® 1900 and 1950 Series processors, which provide incremental power over CPU processing. ATI’s Radeon® X1900 and Radeon® X1950 Series process the complex calculations of the simulation and render advanced 3D visualization of the protein folding process in real time.
Folding@Home will help researchers uncover how certain diseases develop, including:
Stanford University’s research team discovered that ATI’s Radeon X1900 and Radeon X1950 Series of products provide 20 to 40 times faster processing over CPUs in many of the calculations needed to simulate the folding of proteins.
What is Protein Folding Proteins are necklaces of amino acids – long chain molecules that drive all biochemical reactions in the human body, helping to build bones, muscles and blood vessels, and helping the body fight infections. To accomplish these tasks, proteins must take on a particular shape, or, to “fold”. Proteins that fold incorrectly can cause complications and can lead to critical diseases. Folding@Home simulates the folding process to understand why proteins don’t fold correctly. The findings will help researchers prevent and cure these diseases.
You Can Help Find the Cure Folding@home uses distributed computing to simulate protein folding – instead of using super computers, the workload is broken up into small work units and distributed across 100,000’s of PC systems over the internet. When users throughout the world download and run the application they directly contribute to a good cause through the power of their ATI graphics processor. The GPU version of the application will use the processing power of end users’ GPUs to accelerate the simulation and provide data to Stanford’s researchers faster.
Every new PC that runs the application gets us closer to the cure.
You can help by simply downloading and running the Folding@Home application developed by Stanford University. The application is free and secure. It will run in the background, making use of spare GPU capacity in your PC, without impacting the performance of your other applications.
You can increase your contribution by forming and joining teams and competing against others. Contributors are assigned a score indicating the number and difficulty of completed work units. Rankings and other statistics are posted to the Folding@Home website.
Please note that, currently, only the following products in ATI’s Radeon X1900 Series and Radeon X1950 Series can run the application. We will post information about upcoming products that will support this application in the near future.
Radeon X1900 Series: Radeon X1900 GT, Radeon X1900 XT, Radeon X1900 XTX, Radeon X1900 CrossFire Edition
Radeon X1950 Series: Radeon X1950 XTX, Radeon X1950 CrossFire Edition
The X1900 and X1950 series is supposed to increase computation by 20x to 30x. This is accomplished using the 48 pixel shaders in the R580 GPU. That will make an enormous difference in folding times for F@H.
If Santa leaves one of these video cards on your fireplace, please pop a F@H core onto it and tell us what results you experience.
Tech support is available on this thread for users wanting to begin folding for Team 36120 Free Republic Folders!
Pinging the F@H group. With Wild Wednesday and Black Friday upon us, surely someone will have the pleasure of a new toy!

Sorry, I've got no time to read F@H threads...I'm busy reading all the Black Friday ads and figuring how early I have to get up to get what I want (need?)at Fry's. Do you think 4:30 am is too late?
How does it work?: You download a safe, tested program (see link below) that is certified by Stanford University. It gets work from Stanford, runs calculations using your spare computer power, and sends the results back to the University.
Is it safe? Yes! Folding@Home rarely effects computer performance in any way and won't compromise your privacy in any way. It only uses the computing power you aren't using so it doesn't slow down other programs.
How do I get started folding for Team FreeRepublic?:
1.) Download the folding program from Stanford University's folding download page (Folding@home Client Download). Type in your desired username.
2.) Type in 36120 for the team number. THIS IS VERY IMPORTANT - if you get the number wrong, you won't be folding for team FreeRepublic!
3.) The third question asks, "Launch automatically at machine startup, installing this as a service?" - We recommend you answer YES. Otherwise you will have to manually start the program after every reboot.
How can my computer help? Even if they were given exclusive access to all of the world's supercomputers, Stanford still wouldn't have as much processing power as they get from the supercluster of people's desktop systems Folding@home relies on. Modern supercomputers are essentially a cluster of hundreds of processors linked by fast networking. But Stanford needed the power of hundreds of thousands of processors, not just hundreds.
There's no reason to not get involved! It's free, easy, and you can know you're helping every minute without lifting a finger.

It is too late... everyone will be lined up before then at the doors, :-).
BTW, where are you finding ads? I just want a food processor and I can't find a single one with a decent price.
Just make sure that your pup tent is cleaned out after waiting in line to get a PS3.
Fry's? Thank G_d that Denny's stays open all night. 4:30 may not be early enough.
Found this: Sony H2 6mp/12X optical net price after MIR of $305
but I can help you on the food processor
>I just want a food processor and I can't find a single one with a decent price.
KitchenAid 9-Cup Food Processor $149.99 @ Sears
Kohl's Friday Door Buster (6:00 am to 10:00 am)
Cuisinart 7-cup Food Processor
Correction: Kohl's early bird specials are 5:00 am to noon.
People will line up starting at 4:30 am.
well I've just upgraded one of my machines from a Athlon 3400+ to an Opteron 170 (dual core) running at 2.5ghz and have the 502 console running 2 sessions at 95%.
Hey Hay Hey,
We're up to 63rd Place. Not bad for a bunch of troglodyte xenophobic mostly-Christian rednecks.
Wish I had a server farm of my own, but my little intrepid desktop has gotten me to #200 on Team Reagan.
I've pinged my Type I Diabetes list, as glucose metabolism will likely be more completely understood as a result of this research. In fact, Project 2124 specifically is designed (in layman-speak) with diabetic side-effects in mind.
What could also come of this, speculating, is more efficient transfer of energy from the glucose/carbohydrate molecule. That means either better booze or sugaring up the gas tanks of the future.
Thanks a mil, Tex. This is fun. No problems running F@H at all, except during #%#&%&& Windows Updates that demand a system restart.
I am torn. I could get that system online today from Macy's for $90. Or, I can get a unit at Walmart for $50.
But, I love the links, thanks guys!!!!!!!!
IKEA has a "vegamatic" available for $9.99.
I have only been folding for a few weeks and I'm all most in the top half at FR and all ready in the top quarter of all folders. This probably says more about the activity level of some of the folders than about me.

Happy Thanksgiving to all y'all!
If you're interested in tracking your folding machine(s) over the web, please Freepmail me.
Available features include:
I've heard about the new GPU folding client. Sounds like it really rocks. I wonder if they could be used for doing crypto as well.
HAHA!!!!! I had to go look up Veg-o-matic for half an hour to see what you are talking about. No, I don't need a french fry maker (that is what I had one for years and years ago).
I need one that will make a paste or grind cookies down to crumbs for a pie crust, :-).
Aren't we just about at our 1 year anniversary?
We've done a lot of folding in that 1 year.
Officially I started the group in May of 2004.
systematic and soccer_maniac started publicizing Folding@Home over the Thanksgiving break. They deserve the credit for making it the broad team that it is.
May have to post an anniversary thread soon!
If one of the new ATI units gets installed, will the running F@H app auto-sense the new hardware, or does a different version need to be downloaded???
p.s. still folding between 91st-95th place since mis summer :)
The X1600,X1650, and X1800 will fold.. not supported... have to fool device manager...(need d3dx9_30.dll)... need a PCI-E board ...CTRL-ALT-DEL will close client.....some "known issues"... will get lag every 4-5 seconds...pump up the GPU clock and voltage... not a sure cure.
Ummmm, thanks dfw...I think.
I'm just gonna stick with my own dual-core for now. It ain't broke, soooooooo...
Is that good? bad? normal?
Vid chip--I have a NVidea GeForce 7600 GS--I think it's doing pretty goood, not sure.
It really depends on which WU your doing at the time. The easiest way to compare yourself to other FReepers, is to download and install Egon's monitoring program, build up a little history, and then check your times for a project, compared to others. This is done by clicking on a project name listed under your computer. Egon has put a lot of time and effort into this tool, and it is well worth using.
The 7600 is a good card, but you can't fold off it's GPU. Stanford has a new client that allows you to use your GPU to process WU's. When I first read about it, I was thinking "Hey, for a few bucks, I could throw a new card in my box, and double my output". Well, it's not quite that easy. Unless it's an idle box, or you really have a reason to take the pressure off your CPU, IMO right now it doesn't seem like a good idea, because your replacing your CPU, not adding to it. This whole deal is still Beta though, and I'm sure it will only get better.
Ditto here....for now. But I'm thinking I may build a new box after the first of the year, just to play with this.
HAPPY THANKSGIVING to all my FReeper FOlding FRiends !!!
Thank you. Happy Thanksgiving to you and yours. Just stopped in to see if my wu was still chugging along. Back to cooking and herding grandkids out to the yard. :-)
I dropped into my local CompUSA to look at deals on X1900 cards. Almost got one for $190 but they seem to be sold out chain wide. Real bummer.
I will try to grab one by Christmas and start the experiment, if I can get it by the Finance Committee.
Hmm, where are those diamond ads I saw last week?
The Diamond X1950pro 512 is suppose to be available in AGP. I'm not sure if now, or in a couple weeks. Probally reasonably priced too.
There should also be a price drop on the X19xx whan the 8800 settles down price wise. Not sure how long that will take though.
I almost bought the thing I saw in Ikea just to see if it really worked.
We're Number 60!
At least there is something to celebrate this weekend.
First Texas, now Notre Dame. What a waste of TV time.
pbrown is now over 10,000 points!! 5 days, 4 competed work units.
How many systems are running to pop these work units?
I didn't get up until halftime of USC/Irish, and, even then, found other programming more interesting.
Heck, even the Grambling/LA Southern game wasn't that good. And I missed the halftime show.
NFL tomorrow. Life will resume normalcy.
I watch very, very little TV, mostly sports. I couldn't believe that I chose to drop a couple of hours on these games. At least the few minutes of UGA and GT I saw were pretty good.
My NFL is done for the weekend. Now that Tony Romo is leading the Dallas Cowboys to the Stupor Bowl all is well. I will just show up in January (or Feb) and I am sure that Dallas will once again conquer all. That's what I heard on Talk radio today, and we all know how reliable Sports Talk is ...
What a topsy turvy season for the former Cocaineboys. Beat Indy, lose to the Deadskins. Good thing I don't gamble.
Why doesn't Barber start in the backfield?
I only have one, it's an XPS. My son keeps telling me I have a powerful computer. I'll take his word for it. I guess it's a good one then, huh?
You are doing very well for only having one system.
