Comparing a project that runs entirely on GPUs to a project that primarily runs on CPUs is going to lead to lopsided numbers. | |

I disagree. Why? Because as long as I'm a point whore, it doesn't really matter now does it? I'm not the scientist who's trying to get some research done, I'm the guy who just lends his PC to science, however my PC is being used is irrelevant to me, all I see is just a bunch of credits. It's not my fault if my PC is being used or abused, & paid for the hardware, I pay for the electricity, & I paid for the Internet connection. | |

SETI has been running for a Very long time and can use CPUs as well as GPUs. This is a GPU based project that uses top end GPUs. | |

I'm not only doing this because I'm a point whore ;-) If SETI@HOME had something to do with what's going on here on Earth, maybe I'd have chosen them too! But even if they do find ET, that won't be relevant to anything in my lifetime, nor the lifetime of my children, or children's children, etc, etc... | |

Just one clarification: GPUGRID gives approximately the same amount of credit per floating point operation as SETI (faq). High end GPUs provide FAR more ops/second than CPUs. | |

Just one clarification: GPUGRID gives approximately the same amount of credit per floating point operation as SETI (faq). High end GPUs provide FAR more ops/second than CPUs. ~and~ SETI has been running for a Very long time and can use CPUs as well as GPUs. This is a GPU based project that uses top end GPUs. If you both were responding to my statement, I think you misunderstood what I was saying. (Which means I didn't express myself clearly enough. Mia culpa.) I was comparing SETI's GPU multibeam (MB) application vs GPUGRID. I was not comparing a GPU to a CPU. Same GTX280 crunching everything. Using just the GPU (no CPU tasks from SETI), over the same period of time, GPUGRID and and Milkyway produce roughly the same amount of credits, whereas SETI generates only about 1/2 to 1/3 the credits. Of course, in my view, that's 100% arbitrary and meaningless, but as long as we're discussing it, that's what I'm seeing on this GPU. This field being what it is, however, the data I'm seeing may be different than someone else with different hardware and/or a different computing environment. But on this computer, for the same amount of time spent crunching on the same piece of hardware, SETI gives a lot less credits than GPUGRID or Milkyway. Considering the large differences in credits between projects, I'm more surprised that Milkyway and GPUGRID are so close to each other than I am that SETI is so different. | |

AFAIK, SETI gives a (precalculated) amount of credit per WU. So it is unimportant if it was crunched by a CPU or a GPU. And it is possible to have a "CPU-result" validate against a "GPU-result". Michael ____________ Team Linux Users Everywhere | |

True, but if you're a self-described credit-whore like the OP then it really doesn't matter WHY there's a disparity; it only matters that the disparity exists. You get less bang for your buck crunching SETI on your GPU than you do on other projects. | |

Hey, that was nasty & low! I've got a sense of humour & a lot of self confidence. It's ok if I call myself a credit whore, but be careful when you call others that. | |

Hey, that was nasty & low!I've got a sense of humour & a lot of self confidence. It's ok if I call myself a credit whore, but be careful when you call others that. Eep! No offense intended (which is why I was using your words.) Although I personally think credit is a meaningless reason to participate -- I'm also a gamer (dating all the way back to arcade games like Pong, Asteroids, and Space Invaders) and competition IS fun. More importantly, if credit brings people to your project, then it's doing its job! :) What about if some were to be awarded prizes or even cash? There are Projects that do that too. Are there really? Wow. But did you ever consider that stress, & therefore wear & tear to the GPU should be considered when giving credits. Also the fact that power consumption costs money & the bigger the GPU, the greater the power bill. Absolutely. In fact, after a discussion here a year ago about wear & tear, I stopped running BOINC after considering the possible effects on component longevity. I changed my mind eventually, in part due to the lifetime warrantee from EVGA, but it is a consideration. And I also tend to run BOINC more in the winter than the summer. It's easier to justify the extra power consumption, heat production, and carbon footprint when it's contributing to heating the house than in the summer when it's working against the air conditioning. | |

Ibercivis has prizes that you can win (Although I think you have to be Spanish to qualify winning a prize). I've seen some Projects that I didn't dare sign up for, they sounded fishy & didn't use BOINC, by their own VM-Ware PC that (God Forbid!) might turn your PC into a Bot, because they insist that you be online 24/7. | |

It would be nice if someone could make a Water Cooling System, where the external part of the System actually was formed & fashioned to be a radiator. That way, it might even be possible to place it in another room(for Summer). So which is more expensive and/or environmentally unfriendly? Running a conventional water cooled OC'd system, considering all the electricity used (especially in summer with the air conditioning on), or... Run water from your house's plumbing continuously through your water cooling system. Ditch the pump. Ditch the reservoir. Relatively cold water flows from the tap through the blocks on the CPU and GPU and then down the drain. Zero electricity is used cooling the system, and the waste heat goes down the drain, literally. You can use a valve to control the water flow rate, and hence the cooling and component temperatures. Even more extreme would be to use a liquid nitrogen tank instead of water. Liquid nitrogen is crazy cheap. But you'd have to get the tank refilled every now and then, and there are dangers involved (not just the obvious danger from the cold, but if you fill your house up with nitrogen, you could suffocate.) A long time ago (a REALLY long time ago) I used to do laser shows, the kind that rock bands use. The lasers used for those shows are big suckers and use a whole lot of power and produce a whole lot of heat. They're water cooled, as in you hook a garden hose up to them to provide the cooling water. Then again, we didn't run those things 24/7 and we weren't the ones paying the water bill. Or the equally impressive electric bill. :) | |

But don't take a good ide the wrong way. Yes I do use the means that I have at my disposal. If I had more money to spend, I could do a better job to save the Planet. But I don't so I make do with what I have. | |

I'm not sure I follow you -- I think what we have here (to quote an old movie) "is a failure to communicate." | |
ID: 15194 | Rating: 0 | rate: / Reply Quote | |
I guess it certainly was a failure to communicate or at least to understand, because I wasn't on the attack, nor did I mean to attack you. I was simply being humorous. Of course I did not think about that water comes cheap in some countries, but water costs money here, plus it's drinkable too! | |

I know the liquid nitrogen thing has been done at least in the lab. Somebody OC'd the heck out of a brand new processor a few years back using liquid nitrogen. It might have been either Intel or AMD that did it. Shouldn't be too hard to Google... | |

Damn! The things I could do, if I had a 23x multiplier & something to cool that baby down! Even if it fried, I could get 30+ for the price of 1 extreme edition! | |
