For the moment i have a GTX 260 and 280. The current BOINC client (6.3.8) should detect multiple GPUs and run one GPUGRID instance per device. However, we have not yet tested this feature so cannot guarantee that it will work. MJH | |

I must find some time in the week, may be for this week-end! I will try it on Ubuntu and Windows if i can keep the GTX 280. Jim PROFIT | |

The current BOINC client (6.3.8) should detect multiple GPUs and run one GPUGRID instance per device. However, we have not yet tested this feature so cannot guarantee that it will work. Hi, I tested BOINC 6.3.8 on UBUNTU with 2 GPUs (nVidia drivers 177.13). Boinc client really detects 2 GPUs but does not run them together (8400 GS and 8800 GTS, both already tested on GPUGrid positively). If U prefer I've also a 8800 GTX to be used instead of 8400. I aborted calculations, need suggestions. How can I report something to U ? P.S. I tested also on windows VISTA 32 but BOINC 6.3.8 detects only main coprocessor (GPU, 8800 GTS) - (nVidia drivers 177.35) | |

The current BOINC client (6.3.8) should detect multiple GPUs and run one GPUGRID instance per device. However, we have not yet tested this feature so cannot guarantee that it will work. Any two would be fine at this point to test. The current client should try to run two workunits at the time if the client recognize two GPUs. Does it happen? gdf | |

Does the Windows version not support multigpu? | |

Does the Windows version not support multigpu? This is something to start off with. So, you are on client 6.3.8. Can you paste here the message where the client report two GPUs? The application should work. gdf | |

Does the Windows version not support multigpu? When I run Boinc v6.3.8 after the "development" warning, and it's listing of my Computer info it shows: CUDA devices found Coprocessor: GeForce 8800 GT (1) Coprocessor: GeForce 8800 GT (1) ____________ Down with the Kredit Kops!!! | |

Does the Windows version not support multigpu? I would suggest turning on debug flags for the scheduler. When I did this I got messages like this 8/20/2008 12:56:04 PM||insufficient coproc CUDA (1 + 1 > 1) Which for me is correct since I only have 1 GPU it can not run 2. This probably would help find out why it will not run 2. | |

I would suggest turning on debug flags for the scheduler. When I did this I got messages like this Is that what is explained at http://boinc.berkeley.edu/wiki/Client_configuration , in the CPU scheduling bit? ____________ Down with the Kredit Kops!!! | |

I would suggest turning on debug flags for the scheduler. When I did this I got messages like this Yes. Basiccaly you need to do this, note this will generate a lot of messages in your log. You should exit the core client and manager Create in you boinc data directory if not present the file cc_config.xml If you already have one add (edit) into it in the approptriate section. <cc_config> <log_flags> <cpu_sched_debug>1</cpu_sched_debug> </log_flags> </cc_config> Then restart and observe log and look for any lines which might expalin what is going on about the GPU or cuda device. When done, you need to exit again, remove debug lines and then you can restart normally. | |

It's saying "20/08/2008 23:45:59||insufficient coproc CUDA (1 + 1 > 1)" | |

It's saying "20/08/2008 23:45:59||insufficient coproc CUDA (1 + 1 > 1)" Thanks for the testing. I've reported this to the developers to let them have a look into, I think GDF is asleep now. If they need more info I'll let you know. | |

It's saying "20/08/2008 23:45:59||insufficient coproc CUDA (1 + 1 > 1)" Thanks :) I tested it in Linux encase it was a windows problem (only had the 2 8800GT's in the system a week), and I also get the same error :( I also tried removing the SLI cable, to see if that was causing a problem. But still no Joy. ____________ Down with the Kredit Kops!!! | |

I'm told by Dr.Anderson a fix for this has been checked in, It should appear in the next client release also. | |

I'm waiting until the new Windows app is released before I give it a try. | |

Boinc 6.3.9 is not working for me on Windows XP x64 either. | |

Boinc 6.3.9 is not working for me on Windows XP x64 either. A new BOINC version which fixes the Client crashes on Win 64 and CUDA detection should be out later today or tomorrow! ____________ pixelicious.at - my little photoblog | |

A new BOINC version which fixes the Client crashes on Win 64 and CUDA detection should be out later today or tomorrow! Are you able to confirm that the new 6.3.10 has fixed the problem? Thanks, MJH | |

I wait for the Linux version which will support multi GPU. | |

The new application 6.3.10 for linux is ready to download. | |

The new application 6.3.10 for linux is ready to download. I can see that you are crunching on both GPUs, the GTX260 and GTX280, but are you doing it at the same time? Do you have two WUs running at once? gdf | |

Member Feuerkater from our team is able to crunch on two 8800GT in parallel, so basically it works :) He is using 6.3.10 on Vista 64bit. | |

Yes both running at the same time. Member Feuerkater from our team is able to crunch on two 8800GT in parallel, so basically it works :) He is using 6.3.10 on Vista 64bit. For me, it's just on XP x64, and on Vista x64, Boinc see only one GPU. Maybe i have to use the same GPU. Jim PROFIT | |

Boinc see only one GPU. If you have multiple GPUs, you'll need to disable SLI mode in order to use them both for crunching. MJH | |

Boinc see only one GPU. I have run GPUGrid using two GPU's simultaneously with Vista 32-bit, with no problem. I had previously got them set-up while running the Folding@home Nvidia GPU2 client, and had to manually flip a chip on my motherboard to enable both cards to run simultaneously. On Vista I have to have two monitors hooked up for both cards to run, otherwise Vista does not recognize the second video card. XP I understand is more forgiving. Regards, Bob P. | |
