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:
Cancer
Alzheimer's Disease
Parkinson's Disease
Huntington's Disease
Osteogenesis Imperfecta
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
If you two instances are running then we can just leave them alone.
The set advanced methods should be set during installation. I am a little concerned that you did not set the machineid= 1 or 2.
Let it run overnight. Then look at in each folder at the "unitinfo.txt" file. That will tell you what you are running and what the progress is.
I didn't. I hit the download and it didn't ask anything of me when it said files downloaded. Can I just get rid of it and start from scratch?
Note: Please read the license agreement (FAH504-Console.exe -license). Further
use of this software requires that you have read and accepted this agreement.
The file FAHlog.txt has been locked by the operating system and cannot be
opened for writing (possibly because it is open in another application).
Before you next run F@H, please ensure FAHlog.txt is not open anywhere,
or simply delete it. For now, FAHlog2.txt will be used.

TB, I would reccommend she does a search, and dumps all instances of FAH, and starts over. Sounds like the old one is still there.
dfwddr is right. F@H is pulling the existing WU and client.cfg, not allowing you to reinstall the program.
Check your FReepmail.
Life will soon be good.
Hey, we made it up to #58.
Great things happened While You Were Sleeping.
Thanks, both of you. Better I lost it now than when I was almost finished with another wu. I'll check my mail.
I was just researching the DU team, and they're scheduled to overtake "TITS ----> ( . Y . ) <---- TITS" (remember them?) in 20 days.
What do you bet they choke ?????
Well, the guys will brush right past them trailing a fucia boa.
Now the DU womyn may stop folding while they pass just to stare.
In case they ask, yes those "TITS ----> ( . Y . ) <---- TITS" are real.
DU has leveled off at 10,000 PPD and may soon drop below that for good. They will have a very hard time making it to 140.
Has DU even had a folding thread lately?
I've randomly searched for one over the last couple of months, and haven't found one. Some other quick DU stats, to bookmark the date, they have 63 ppl with a PPD avg (#63 = 1 PPD), and 57 with points this week. They theoretically could get to the #59 position, but it would take them a bit over 15 years, not counting overtakes. With overtakes, and a declining PPD, they'll be lucky to reach 100.

That looks very good. And you will like the Double Groamcs core for points.
The easiest way tell if both WUs are working is the old CTRL-ALT-DEL. If you see two cores running then all is well.
I'll remember that. Thank you for all your help. Now I can go to bed and let it do it's thing. :-)
What on earth did I do wrong, and is it fixable?

Actually everything is fine. Its just chugging right along.
I would perhaps set the checkpoint save time to longer than 3 minutes, but that is a minor nit.
Now we know that the second core is happy. How is the first F@H doing?

It showed 63% completed when I checked this morning.
Saving extra checkpoints is no big deal, especially since you have electrical problems.
Maybe a cheap battery back up for Christmas?
I'll post later when I get to work.
I have double AA's, will that work? Just kidding. My daughter will know what I need, I'll ask her. I am getting a beautiful new desk though, the furniture store let it slip on their delivery date. Hubby will never know I know. Bless him. :-)

Can I just backspace on my checkpoint=3 and get rid of the constant checkpoint breaks?
No, you need to have a setting between 3 and 30. I keep mine set a 30 minutes in most cases.
15 minutes is the default and works OK for most folks.
