30k ps3= 1 petaflop
----------------------------------------300k ps3 = 10 3mil ps3 =100 petaflops per second come hook up ur ps3 what u waiting for?:) check this out freakin amazing This is freaking amazing. I was checking out some message boards last night at the Folding Forums at Stanford, a group that tracks the Folding at Home application. You know, that's the software that runs on Sony PS3 or PS2 gaming consoles, all linking up over the Internet and using their spare cycles to help the university process vast amounts of Alzheimers research data? To my astonishment, I discovered that a small legion of 13,000 PS3s running the Folding at Home app account for most of the computing power in the project, amounting to about 56 percent (PS3s = 316 measured TFLOPS) of the total. On average, between the superfast and superslow PCs, 159,033 PCs are only doing about half that much. (151 TFLOPS). Essentially, 13,000 PS3s have just made the Folding at Home Project the fastest distributed computing project on the planet, ever. (I believe it used to be SETI @ Home, which was something like 280 TFLOPS.) This also means the PS3 met Stanford professor Vijay Pande's expected one-month goal in one day. (We'll update this post with confirmation once Dr. Pande gets back to us. http://gizmodo.com/gadgets/home-entertainment...spitting-range-246664.php [Edit 2 times, last edit by Former Member at Mar 24, 2007 10:47:01 PM] |

Please stop spamming with the same old topic.
This particular topic got old months ago. Have a look here for previous discussion, and more importantly, some BENCHMARKS, which seem to indicate you are totally misinformed. Sorry. http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=10181#79193 But really, it doesn't take a genius to figure it out. If consoles were so amazing, we would all use them for our general purpose computing. They simply aren't. The console manufacturers just do a great job of distorting and misrepresenting the actual power of their product. |

POINT IN CASE
----------------------------------------THE CELL CPU DOSE 20 TIMES BETTER FOR FOLDING, THEN GENERA;L CPU FOR GENERAL CPMUTING, I DONT NEED A TERAFLOP GENERAL CPU FOR WE SURFING OR FORUMJ POSTING, SOO A CELL CPU= A T LEAST 10 REGULAR CPUS watch youtube video http://www.youtube.com/watch?v=VoMHnKMD_Aw 901 teraflops tomorow sunday, 1 petflop wiill be pased [Edit 2 times, last edit by Former Member at Mar 25, 2007 12:36:01 AM] |

How exactly and what is "TFLOPS" supposed to measure?
20x faster seems to be the most conservative number I've seen. http://fah-web.stanford.edu/cgi-bin/main.py?qtype=osstats I've calculated it to be ~26x more than PCs which isn't too far off (702TFLOPS/28672)/(153TFLOPS/160524). That figure is probably inflated, considering most of the PS3 Folders are probably sitting there collecting dust, and the PC Folders are either ancient Celerons or busy doing something. === And that's just "TFLOPS". http://fah-web.stanford.edu/psummary.html There I see PS3 constituting 12/100+ WU. The PS3 WU's don't award that much (compared to Gromacs)... So how in the world is PS3 getting such a high TFLOPS number? |

Also, on that link, 264 333 264 333 576 576 576 576 582 582 582 582 are the number of atoms per ps3 work unit? A few of the seemingly non PS3 work units.. 19399 6115 1135 14917 14836 91787 91787 87920 25541 18894 126006 77373 126006 308047 |

GPU folding is pretty effective too

I see that the tone of the messages that some of these PS3 posters maybe taken as an insult or flamebait by the WCG users here, as it is for a completely different project. The result of this tone is that the replies try to dispute the original post or somehow dismiss this as old or irrelevant news.
----------------------------------------However, I believe that any improvement to open a new technology more to some humanitarian project (or at least some project that a user believes is worth contributing to) is good news. I can see how some WCG members may be peeved that F@H is getting a lot of press and due to their new PS3 client and WCG is not mentioned at all. Especially, when it is being multi-posted here by the same person, it may be taken as an effort of rubbing it in rather than something useful. But perhaps a silver lining is that this new technology may end up encouraging the regular CPU users to move their processing power to where their work will be more useful. It's common knowledge that a good percentage of people just enjoy playing the stats and points game. With the high efficiency of the PS3/GPUs, perhaps these regular CPU members may feel that they can no longer compete in this "game" against PS3/GPU users that can crunch the same WU in 1/10th the time. And indeed if the numbers are true, the CPUs are no longer contributing significantly as compared to the GPU/PS3 clients for F@H. So for those feeling slighted by these PS3 news and posts in WCG forums, view the bigger picture, the more processing for F@H potentially frees up resources to go to other distributed projects. So for those looking for something to take from this, go forth and at least inform the CPU users at F@H to leave from their obsoleted job of doing F@H WUs to some other worthy distributed project where they can use their CPUs to do a job that no other tool can do better or faster. An analogy is that the F@H project can be thought of as having to cut a huge grass field. Regular CPUs are like scissors, and the new PS3/GPU clients can be though of like inventing a lawnmower. Why use your 200,000 people armed with scissors to cut 1/10th of the field when you have 20,000 people armed with lawnmowers that can cut 9/10s of the field. Instead you might use your scissors to do specialized tasks that only scissors can do: haircuts (other distributed project like WCG). Well, at least until they invent the equivilant of clippers (GPU/PS3Client for WCG) [Edit 1 times, last edit by Former Member at Mar 25, 2007 8:39:44 PM] |

I like your thinking. Hopefully more with PS3s will fold on their PS3 and find something new for their PC. Or, PS3 power will dominate so much that PC contribution is negligible so they'll venture into WCG.
But I still want to know.. Assuming that they are capable of doing all WUs (which I know they aren't), those stats.. Essentially, PS3 is crunching 70% of all work now? Or is it just crafty accounting of TFLOPS.. |

Smoke and Mirrors...
When Stanford University sold their academic souls to Exxon Mobil a couple of weeks ago for, of all things, climate research I understand. WCG is non-profit, with alot of voluntary help, running one of the most prolific and successful grid projects in its' short hitory...A U.S. Attorney said it right. Follow the money. Some people in this world of ours would love all this vast fund of research and computing power to be EULA'd, restricted privatized, and profited from, at the expense of humanity. That is what all this so called great new stuff is really about. When Philip Morris Tobacco gives the WCG a $100 million dollar gift, with no strings attached, I will change my tune... ![]() |
