    Default Screen savers saving the world?

    I know that in the past I've seen a number of different groups that have had a Screen saver that when ran helped to break down the human genome, cancer and some other various things that will take hundreds of computers to do. Does anyone know of any such programs?

    I figure if i can have my computer looking for a cure for cancer when I'm not using it, that would be cool or some other good cause it would be well worth it.

    Well, there are a lot of statistics showing that such and such many computer hours have been logged...but I wonder what most of that time is actually spent doing? The time spent is only relevant if your approach to trying to find a solution is in any way effective, and if you'd know a solution if you saw one. I'm not convinced that's the case with these.
    If there's nothing out there, then what was that noise?

    I know of two such projects off the top of my head:

    SETI@home watches the skies for extra-terrestrial radio signals.

    Folding@home analyses protein folding, which could lead to medical breakthroughs.

    I would assume that the parent organizations gain something from these projects, else they would stop supporting them. I don't think either project is necessarily trying to find the answer to its stated problem; rather, it's just trying to narrow it down.

    For example, SETI@home doesn't try to find extra-terrestrial signals. It just tries to find something that might be indicative of an unnatural and uexpected radio signal. These finding are then shipped off to experts who take a closer look for themselves.

    Folding@home has a team thing and like a point system if anyone else on the board downloads the program and wants to make a Giant in the Playground team That would be fun.

    A GitP team sounds like a really good idea. I've gone and created a team called "Giant in the Playground" for everyone who would like to join Folding@Home, Team ID: 82447

    Wow, folding@home did p53! I didn't know that!

    I will have to see if I can install it on my computer then. Then I might actually make a contribution to SCIENCE!

    Oh, one great thing about Folding@Home, is that it is completely non profit and all results are publicly available.

    As far as I know, the system doesn't actually solve anything but mathematical formulas. It basically makes supercomputers via parallel computing open to researchers (normal supercomputers cost ALOT). I'm doing research right now, and on occasion I use a similar network (though it's not publically parallel). Basically, a request for a calculation is put in, the calculation is broken down into parallel parts and a PC does a part while otherwise unoccupied.

    It'll probably slow your computer down abit though, especially in terms of RAM (I'm not familiar with the particular system, but if it does things like analyze protein folding then it might do it using quantum-mechanical calculations, which would take alot of ram).

    The end point for protein folding is finding the lowest energy configuration. This is done by calculating the known energies of bond lengths and configurations from other similar known confirmation's energy values.

    It is theorized that one of the best places to begin attempting to solve a protein folding structure is to look at the lowest energy confirmation, and then adjust for hydrogen bonds, di-sulfide bridges, salt bridges and etc.

    So all this said, yes, with protein folding they have a defined end point.

    But then again, I fell asleep in my lecture on protein folding modeling and protein crystalization. The guy had a monotone, and I was up late the night before cramming amino acid catabolism pathways into my brain.

    Folding@home is fun. My roomie and I both have folding on our computers. He's a bit of a folding addict and even has a little computer that does nothing more than fold.

    Well yes but you can always turn the program off when you need the ram. So if you want to game then you should still be fine if you turn it off when gaming. Right?

    I can't say for sure on folding@home, but typically these types of programs are set up as your screen saver. So they aren't active and aren't consuming any processor time or RAM when you are using the computer. You probably can set it up to run continuously, but that's probably not a good idea on a gaming box.

    See now I can't get it to run as my screen saver that is under the menu but I can't get it to work. I have the program running right now though. Its kinda fun watching proteins fold.

    The University of Washington has a similar program, but I can't remember for the life of me what it is. They had timers that tracked how many hours you logged, and offered benefits to people in the dorms that met certain hour marks.

    Pretty neat way to get a few thousand extra processors running for you.

    No, what I meant about taking up RAM wasn't related to that. Basically, the way it should work is that while your computer is in screensaver, your processor would indeed be working like crazy and your RAM would be used. However, as soon as your screensaver goes off, it would store the data at whatever point it was last at, and maybe send it out. The thing about RAM is, however, that old programs tend to keep their data in the RAM unless it's being replaced by something new. An example is... say... when you have a RAM intensive game going, and then you close it by accident and start it up again it'll start up much faster because alot of the data will still be there. I think.

    The end point for protein folding is finding the lowest energy configuration. This is done by calculating the known energies of bond lengths and configurations from other similar known confirmation's energy values.

    It is theorized that one of the best places to begin attempting to solve a protein folding structure is to look at the lowest energy confirmation, and then adjust for hydrogen bonds, di-sulfide bridges, salt bridges and etc.

    Hehehe

    No, that's the way most of it is done. I'm running lowest energy configuration simulations for silicon nanowires as I type this. I would assume because protein systems are much larger in terms of atoms and have many different types, the calcuations would be done with emperical forcefields (ie. classical ones). Those might actually not be that intensive on your computer, especially when broken down. The kind I'm doing right now involve solving huge matricies for numerical approximations to systems, and the upper limit is like 200 atoms on supercomputers anyways.

    Well, yes. But no.

    When the folding@home process ends, it and whatever data it used are almost guaranteed to remain in active memory for some non-trivial time. But, the OS knows those regions of memory are open for use, so when you start your memory-intensive game, the OS gives the game access to those regions. The game doesn't have any difficulty overwriting the folding@home data, any more than it would have overwriting empty memory, or memory used by a dozen smaller, terminated processes.

    Yes, there are circumstances where loading the same data/application as previously loaded could, theoretically, result in shorter load times. But there's no guarantee that it would, and even if it did, once the application was loaded, there'd be no change in performance.
