Hello, I'm runing MW wu's cuda only, using a Nvidia GeForce GTX 275. My computer is a CPU i7 - 860 and Windows 7 64 bits. Everything was crunching correctly until the server upload new WU called 0.50 (cuda_opend) de_separation_16 (or 14, or 17...) _3s_fix_1... Every WU stopped immediatly after the begining, saying there is a calcul error. I am using a regular Boinc client 6.10.43. If someone has any clue, it will help. In advance, thenk you very much. Lionel. |

I just helped Ron on the same problem, your driver is just a little too old for the openCL app. http://www.nvidia.com/object/win7-winvista-64bit-260.99-whql-driver.html |

Well I downloaded the latest driver from Nvidia Web site before posting my thread... |

The site does not show you running it though. It should be 260.99. |

Hello, The problem is fixed. The first installation of the driver didn't work for any reason. So I upgrade Boinc Manager to the 6.10.58 version and reinstall the latest nvidia driver 260.99 (Windows indicates this is the version : 8.17.12.6099, date : 16.10.2010). Then I reboot the computer and WU's are running correctly. sorry to bother you about my problem. I hope the solution will help. Bests regards. Lionel. |

I'm already running the current version of BOINC, but did load the newer nVidia driver today. I'm still getting massive computation errors. Oddly, my older 8600 GT is working fine. My newer GTX 260 is not. |

Correction, GPU-Z indicates that the video engine load for both cards is 0%, but one of them (device 0) is crunching. I don't know, maybe that's the 260, maybe not. I've got a cold and I am not seeing clearly. |

My newer GTX 260 is not.It looks like BOINC is trying to run it on the 8600 which doesn't have doubles so it won't work, which is a problem. |

I don't suppose there is a fix for this, is there? I've got 3 monitors hooked up so I can't just yank the card out, and I'm not going to buy a new card to get around this, so maybe I should be looking for a new project? I'm sure it's going to clog things on your end with all of my computation errors being returned. |

I'm sure it's going to clog things on your end with all of my computation errors being returned. If you do not want to crunch on the 8600, there is a way to exclude it via a cc_config.xml file |

I changed the value from 1 to 0 and that didn't help on "use all gpu's" in the cc_config.xml file. Is there a different way to word this so that the 8600 doesn't grab more WU's? |

How do I use only one of my multiple GPUs? You can tell BOINC which GPU to ignore using the <ignore_cuda_dev>0|1|2|3</ignore_cuda_dev> and <ignore_ati_dev>0|1|2|3</ignore_ati_dev> flags in the <options> section of cc_config.xml GPUs are counted per brand and from the first in your system to the last, while the first GPU of the same brand is designated GPU 0, the second GPU 1 etc. So for example, you have a 3 GPU system, two Nvidia and one ATI. You only want BOINC to use the first Nvidia and the ATI, not the second Nvidia. <cc_config> <options> <ignore_cuda_dev>1</ignore_cuda_dev> </options> </cc_config> http://boincfaq.mundayweb.com/index.php?language=1&view=471 |

OK, when I saw the new (.50) workunits, I checked and saw I needed updated drivers, and installed 260.99 on both my systems. The remaining (.24) units ran through, creating output files which are still waiting for upload. The (.50) units also ran to completion in typical times for my GTX260 cards, but instead of creating files for upload, they went straight to "ready to report", even though the project was, and is, "down" for all intents and purposes. Is there still a problem with the new version? I can't think of anything on my end that could be wrong. |

There isn't a special output file anymore. |

I get these errors ([url=http://milkyway.cs.rpi.edu/milkyway/result.php?That's weird, but I might have fixed where this probably happens for the next release. |
