GPUGRID has been constantly above the Petaflop in the past few days. Although just a symbolic number it feels good to reach such an impressive target for us. | |

Awesome! I guess there are far fewer GPU Grid cruchers, but with the abundance of top notch GPU's on this project I would have thought GPU grid has been above it for quite some time. | |

In fact we have so much incoming data that it's becoming hard for the server to keep up. We are working around the clock to keep the pipes clear. | |

Congratulations for all crunchers, such a big milestone! | |

Generally one of the nicer problems to have :) I imagine that the new(ish) 4.2App had a fair bit to do with getting this project over the 1PF line with it's massive increase in efficiency. | |

Woohoo - Congrats GPUGrid - broken the Petaflop barrier again! | |

WooHoo indeed. I hope we can make it to 2 Peta Flops with the Titan and 780's now fully on board. | |

33.86 petaFLOPS is the present fastest non-distributed supercomputer. | |

So, just wondering: How much GigaFLOPS does say a 780 put out for this website's app? Meaning, if a 780 were left running at stock 24/7, how much would one increase the sites performance? | |

With nothing holding it back it should be 4 Tera Flops (or just under) of single precision FPO which is what GPU Grid uses. | |

The theoretical single precision GFlops of the main Reference spec cards are shown below. GTX 650 813
GTX 650 Ti 1421
GTX 650 TiBoost 1505
GTX 660 1882
GTX 660 Ti 2460
GTX 670 2460
GTX 680 3090
GTX 690 5622
GTX 760 2258
GTX 770 3213
GTX 780 3977
GTX Titan 4500 For this project most of these GFlops values reflect the relative GPU performances reasonably accurately, but the accuracy of the Ti cards especially isn't great (some higher, some lower). The accuracy of non-listed entry level cards with miniscule bus widths are even worse. Application and system constraints would reduce the acutal GFlops. The power targets/GPU Usage might better reflect the actual amount of GFlops being used. So a card using 90% of the GPU and running at a power target of 90% might only be using up to 90% of the available GFlops. In my experience mid-range reference cards have a high GPU usage compared to higher end cards and would therefore come closer to reaching their reference GFlops - perhaps 90% of the theoretical GFlops would be used (on a good setup). High end cards tend to use less of what's available (say 75 to 85% GPU usage, at least on Windows). The % usage of the TDP's tends to be lower too. Values vary depending on task type. Another consideration is that many cards are non-reference with higher TDP's and clocks. - Good to see GPUGrid back over the 1Peta Flops mark, but I'm not sure where this is taken from or of it's accuracy; Boinc All Project Stats has the value at 2,810.281 TeraFLOPS (2.8 PFlops), and the project RAC at 214M. http://www.allprojectstats.com/po.php?projekt=48 Boinc Stats has the current GFlops at 968.609 TeraFLOPS. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help | |

In addition to what SK said: for GP-GPU it's very good to achieve even 50% of the theoretical maximum throughput. I don't know any more specific numbers for GPU-Grid. | |

Every FLOPS figure you see on a stats site has been derived in some way from the credit awarded by the project. For example, the current figures at Boinc Stats are: Recent average credit RAC 193,721,774
Average floating point operations per second 968,608.9 GigaFLOPS The RAC figure is 199.9999938 times the GigaFLOPS figure: that's not coincidence, that's arithmetic (the definition is 200x, with a tiny rounding error because of limited precision). So, according to BOINC statistics, all a project has to do to increase its G/T/PFlops production rate is to increase the amount of credit awarded per task - and there are some projects which have done that. That's the crazy world of statistics for you. | |

I wonder how much "science" can be done, say per month, at this speed. | |

That's the crazy world of statistics for you. It's not statistics that are at fault, it's the way some people do statistics and what they do with the numbers they come up with. I once had respect for BOINC stats sites but that quickly ended when they started doing crazy stuff like deriving performance (FLOPS) from credits. They pander to the naive, like many politicians do, thereby reinforcing beliefs that have no foundation in reality. ____________ BOINC <<--- credit whores, pedants, alien hunters | |

That's the crazy world of statistics for you. And the real crime against scientific method is that BOINC themselves commit the same sin, in the top-right corner of the home page, and more dramatically on http://boinc.berkeley.edu/chart_list.php. How many of those GFLOPS statements would pass a floating-point benchmark audit? | |

What was the highest value ever on gpugrid? Are the current 1,14PFlop the top value? Good value, not long ago we struggled to go over 1PFlop again ^^ | |
