Message boards : Number crunching : "Error while computing" Task Status
Author | Message |
---|---|
The status of my tasks keeps showing up as "Error while computing". As far as I can tell, I've been unable to get any successful results with GPUGRID since I've started running BOINC again. I've tried BOINC versions 6.12.34 and 7.0.23. I receive this error on two different machines, one with two NVIDIA GTX 260s and the other with two NVIDIA GTX 460s. The NVIDIA driver version on both is 296.10. I'm not currently at home so I can't provide log information or set flags on the machines, but I will be soon if that would be useful. I'm running Windows 7 64-bit on both computers. | |

Just to provide some additional info, I'm noticing that SETI tasks are reporting the same status. The online SETI logs state that no CUDA devices are being found and that crunching is falling back to the CPU. A computation error subsequently occurs. | |

Based upon what I'm seeing in other threads, it looks like the NVIDIA driver and monitor sleeping might be to blame. I'll try an older driver and post back with my results. | |

I was just going to post that. Try using the 285.63 I think, its a WHQL driver. Sounds like the issue. | |

Thanks for the suggestion 5pot. The 285.63 driver has made a definite improvement as far as SETI tasks go (no more claims that CUDA devices cannot be found), but GPUGRID seems to be a different story. I'm still seeing computation errors. I'll post the stderr output available online for one of the failed tasks below. <core_client_version>7.0.23</core_client_version> <![CDATA[ <message> The system cannot find the path specified. (0x3) - exit code 3 (0x3) </message> <stderr_txt> # Using device 0 SWAN: FATAL : Unable to enumerate devices Assertion failed: 0, file swanlib_nv.c, line 390 This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. </stderr_txt> ]]> Any ideas? Thanks again. | |

Below is a slightly different version of the stderr output that is also popping up. <core_client_version>7.0.23</core_client_version> <![CDATA[ <message> The system cannot find the path specified. (0x3) - exit code 3 (0x3) </message> <stderr_txt> # Using device 1 # There are 2 devices supporting CUDA # Device 0: "GeForce GTX 460" # Clock rate: 1.44 GHz # Total amount of global memory: 805306368 bytes # Number of multiprocessors: 7 # Number of cores: 56 # Device 1: "GeForce GTX 460" # Clock rate: 1.44 GHz # Total amount of global memory: 805306368 bytes # Number of multiprocessors: 7 # Number of cores: 56 This application has requested the Runtime to terminate it in an unusual way.

You don't have SLI enabled do you? | |

Yes, I do have SLI enabled. Does SLI cause problems when crunching? | |

I would highly recommend disabling SLI, i think this may be your problem. Pretty.sure you can leave bridge connected if u game and would like to switch quickly. Computer basically recognize one gpu (in terms of the computer uses it. with SLI enabled. Depending on the coding of project, this may be why it works on seti and not here. [/b] | |

Thanks for your reply 5pot. Do you know if BOINC will still be able to see and use both GPUs with SLI disabled? | |

Someone a lot more knowledgeable than me will probably post tomorrow. I would just wait and see . I'm still waiting for post from message regarding Linux I made earlier today. | |

Sorry its getting late. Thought that said enabled. Yes it should but as I said someone much more knowledge than me.should respond tomorrow[/b]. Things like different boinc version can also cause issues with multiple gpu but.since they're same.card.there should not be an issue i think. Disable SLI and give it a try | |

Yes it should work with both gpus, done that a time ago. If not (possible depends on boinc, drivers and so on) there are some threads about multiple gpu config changes. | |

I think all the answers to all those questions are in the Best configurations for GPUGRID FAQ thread. | |

Good news! Swapping to the 285.63 driver and disabling SLI seems to have stopped the "Error while computing" task statuses. Thanks everyone for your responses! :) | |
