Computation errors
(Message 8792)
Posted 5502 days ago by Scott Brown I have an 8600GT (32 shader) that is returning current work in the 50-52 hour range. The 8400GS (16 shader) with a similar shader clock (around 1500) should return work in just a bit over twice that time, or in other words, will push the 5-day deadline limit per workunit. Given the newly added "server cancels redundant work" feature, I'd be very curious to see how the 8400GS could do. |

Quad Sli Support?
(Message 8733)
Posted 5503 days ago by Scott Brown Unless SLI is disabled (regardless of version), the GPUGRID application will execute on only one GPU. As I understand it, this is not a limitation of the GPUGRID app., but a more general restriction in CUDA (at least until NVIDIA addresses it). |

Posted 5511 days ago by Scott Brown It is a continuing issue from the weekend outage...see here. Hopefully it will be fixed soon. |

Posted 5514 days ago by Scott Brown Power to the monitor and GPU are different...you should be able to set the power to go off on the monitor without affecting you ability to crunch. |

Nvidia 256MB FX3400 or GeForce 9800 GT 512MB
(Message 8360)
Posted 5514 days ago by Scott Brown The 9800GT, because it can actually crunch for GPUGRID. The Quadro FX3400 is based on the NV45GL chip, which is not a unified shader card. Therefore, it cannot be used for any of the BOINC DC projects. Perhaps you mean the G92-based FX3700? If so, they will be roughly the same. In general, the GeForce gaming cards will be faster than Quadro cards having the same shader numbers due to the latter having very low stock shader clocking. When clocked the same, there will be no difference. |

Credit per € [closed / outdated]
(Message 8243)
Posted 5519 days ago by Scott Brown Thanks for continued work on this list. A couple of quick questions/suugestions though... 1) The 8800GTS(320/640) and 8800GTX should really be excluded from the list here since these cards have 1.0 compute capability and, therefore, are not compatible with GPUGRID (The same applies for all of the 870 series Tesla). 2) Your price for the 8800GS is much too high. One can pick up a 9600GSO (96-shader version which is the same card) on Ebay or NewEgg for $70 - $100 US. That equates to about 52 to 75 euros at today's exchange rate. And with that pricing, the 8800GS/9600GSO will come very close to the GTS250 in GFLOPS/euro. 3) If I can find the time (or if anyone else wants to) a comparable US dollar, Japanese Yen, etc. chart would be interesting. Based on some price differences that I see, the best bang-for-the-price card may vary considerably by geographic location... |

Redundent Result
(Message 8125)
Posted 5522 days ago by Scott Brown I understand they are intentional. I was only curious becasue all of a sudden I seemed to get a lot of them. Is a WU marked Redundent result before you ever start processing the WU, during the processing of a workunit, or after you have completed processing the WU? Before. |

You should really consider an OC of the shader and core clocks. The 96 shader 9600GSO (and 8800GS, which is the same card rebranded) is very tolerant of OC if you have good heat management in your system. I have a factory OC 9600GSO and have OC'ed my 8800GS as well to around 1700 shader clock. Modest heat increase, no errors, and increased speed in crunching. This should get you close to having better luck in the quad. As for fixes to this overall issue, a very easy solution would be to define workunit types by there preset credit totals (which are based on flops counting and equate quite nicely to run times) so that users with slower cards could opt out of the longer work. In other words, create generalized classes of work so that there might be four types: 1) less than 2400 base credit, 2) 2400 - 3000 base credit, 3) 3,000 - 3,600 base credit, and 4) more than 3,600 base credit (the number and values of these thresholds are of course just examples). Add the workunit type checkboxes to the user account GPUGRID preferences section (similar to what is done at PrimeGrid) and let users select as needed. |
