PS3 Client for Folding@Home Debuts, ATI GPU Version Soon 177

eliot1785 writes "Stanford's Folding@Home project is reporting that Sony debuted a Folding@Home client for the PlayStation 3 today in Germany. Researchers hope to use the power of the PS3's Cell processor to greatly expand the number of FLOPS of which their network is capable. F@H also announced today that they will release a client capable of running on ATI graphics processors. With these two new developments, F@H hopes to raise the total power of their distributed computing network to 1-10 petaflops. At the upper end of that target, the network would be faster than any current supercomputer, at least in terms of FLOPS." Reader TommyBear points out a collection of papers showing scientific advances made by the F@H researchers.

      Naw... the PS3 is already panned for having too many features... if it cures cancer people are just going to throw up there hands in frustration and go buy a Wii.

      All kidding aside... if you had a PS3 would you run this in down time?

        It needs to be transparant as a screensaver or something. Also, I'm not sure I'd want my PS3 on all the time either unless it handles heat extremely well. Something we've learnt from history that not all consoles do. Even the old Super NES (NES16) used to choke after a couple of days... I've got friends that fried theirs after heavy-duty playing sessions.

        I'm running folding@home at 2 PCs that runs all night (using electric power at night is more cheap than during the daytime). And it's installed on other 3 PCs, so when I'm only browsing the Internet or so, it uses the unused processor.
        So if I buy a PS3, or a Cell personal computer, I'm sure that it is going to run folding@home.

It's a good, round number. And I'll assume that I'd spend an hour per day actually playing games. Electricity in my area costs about $0.08/kW-hr.

    x86 continues to get left in the computational dust.

    I have a friend who is a very senior engineer at NVidia who has talked about how sick and tired they are of having the boat anchor that is x86 tied to their hardware. And that they would love to just cut out Intel and just run Windows/Linux right on their hardware. Microsoft obviously felt the same way when they dumped Intel and switch to PowerPC with the 360.

    The PS3 is supposed to completely support keyboard and mouse, have a full version of Linux sitting on the harddrive, and support homebrew development. If you can download and install normal Linux apps...a graphics programmer dream come true. Even cooler are the plans of Sony coming out with higher end PS3 models with more RAM or Cell chips. A Linux box with a couple gigs of RAM and dual or quad Cells, oh baby.

      Exactly. IBM have been using Linux as the development platform for the Cell processor so it's not as far fetched as it sounds. Sony could have Linux running on the PS3 from the get go. It remains to be seen if they do though or what it looks like... It would be awesome if it did. At that point the PS3 *is* a computer (not just for tax dodging purposes), as well as a kick ass console, media jukebox. When you think of it from that perspective, the price really isn't unreasonable, especially compared to the Mac Mini (for example).

        ISA means the instruction set. I seems all desktop computers currently being manufactured use the x86 ISA, even if they differ internally in the implementation.
    • I'll bet you a million bucks the ps3 has something similar to what tivo uses..

      in fact i'll bet you one of the coprocessors on the cell is just like microsoft's custom xbox360 processor, with on-die signing and encryption keys.

      Yeah, it'll run linux.. a "signed" distribution of linux which will be the only thing ps3 will run.

      why do you think Sony announced it rather than the folding@home coordinators at stanford?

      1) a video card does not contain a general purpose processor and is not capable of running an operating system. It contains a GPU, which is very fast for certain subsets of mathematical calculations, but that is all. It can't effectively branch, doesn't offer memory protection, etc. There are the biggest parts of a modern general-purpose CPU

      2) Video cards are not tied to x86: A video card communicates with a bus like PCI or AGP. The system could be running an PowerPC chip, or a cell chip, or an x86 chip. nVidia has cards that run on all three of these environments.

      3) You talk about the cell processor and the PS3, but that doesn't have anything to do with x86 being left behind. The cell processors are a massively parallel processor designed for running video games and computational problems. It will probably be inefficient (per watt and per cycle) to run a normal desktop OS on it. Not that it isn't possible, but that isn't what it is for.

      4) You point out how x86 must be bad because Microsoft switched to PowerPC for the 360. So why did Apple switch to x86 from PowerPC, and suddenly everything is faster and lower power?

      If you think for a second that Sony is going to "open up" the PS3 and just let you put whatever homebrew software you want on it, considering their record with the PSP, you're living in a dream world. Sony are control FREAKS. Their media-producing divisions are so scared at even the HINT that the system could be used for pirated games/media that they would rather take a financial loss than risk conceding even the slightest BIT of control of their system to homebrew coders.

      If you want to see the kind of "Linux" you'll get on the PS3, look no further than the "Linux" they gave us on the PS2.

      MS XBox or Cell Power arch CPUs are specialised processors. E.g. the MS Xbox 360 CPU has 3 cores. They have problem with desktop application usage.

      I know the Intel or AMD duo-poly has huge impact on personal computing but it is not the case here.

      For example a monster CPU named Power6 will ship in months which will have max speed of 5.7 Ghz. If you remember it is a RISC CPU , you can imagine the huge power. The problem is, it is not cheap, not suitable for home computing and needs very advanced coders.

    There aren't much details on the ATI version. I'm guessing there's no Nvidia version yet because of the lack of IEEE 854 compliance in viedo cards, so they'd have to create a special version for each video card. But it's pretty neat what you can do with video cards these days besides play video games.
    • If you click through some of the links on the Folding@Home site, you'll find that they were originally using Nvidia processors; but, found they got much higher performance with their code on the ATI processors. Therefore they decided to concentrate their efforts on ATI.
      • You're right. I guess I missed that somehow. On the other hand, how much faster is the "slower" Nvidia version compared to the pure CPU version? Unless it's slower (or even if it is), I don't see why they wouldn't make that version available too. But, first things first I guess: finish the faster one and then work on the slower one.
  • The Cell processor is vastly superior to the "Emotion Engine" and yet, Sony doesn't seem concerned that it'll be used to build supercomputer networks by menacing countries...

    The Broadband Engine in the PS3 has roughly 210 Gflops of power at 3.2Ghz. That is around an order of magnitude more than most people's current Intel desktop PCs. Although that isn't really the full story since it is the memory architecture that makes Cell chips so much more powerful than Intel chips, but that is a whole other, very cool, subject. If even a small percentage of the 100+ million PS3s Sony will sell over the next five years are added to computation pool, the results will be staggering.

    • Sorry, but the memory archtitecture is what makes cell suck, relatively.
      Its _extremely_ brain-swelled as a cpu (i.e. many execution units, relatively sucky bandwidth and latency).

      And if even a small number of those 100 million playstations will be added to the computation pool and thus needlessly be running 24/7 instead when games are played then you are going to need a few more powerplants just for them.

        Does power consumption of the Cell lower when not all the SPE's are used? There'll probably be quite a few games that won't use all the available processor power (think games like "Buzz" or dance games). If power consumption remains (relatively) stable, you might run F@H in the background during gaming sessions.

        Memory on PS3 makes it state of the art. It is some maniacal configuration RDRAM (yes, Rambus) configuration which doesn't exist except some custom workstations.

      I found out yesterday that someone I knew last year died of liver cancer over the summer. She was 19. I think it's safe to say that there are plenty of people out there who don't give a flying fuck if Sony gets good press about this. If it brings us a cure to cancer a year, a day, an hour sooner, it's a damn fine thing. I just hope most PS3 owners find out about it, and maybe we can cure cancer.
