Observing when a VHAR work unit appears to stall on my machine, I have noticed that the progress will always stop counting at 0.603%. If this is consistent between other computers it may help isolate what the client program is doing when it stops performing as intended. LumenDan |

I did just installed NVIDIA 441.20 on 3 Windows10 maschines und did run some units. It is looking good. Perhaps the problem is solved? |

Sorry, sorry, I was too optomistic!! The problem still exist. |

It looks like I've had several tasks go into an endless loop, stopped only by the time limit. https://setiathome.berkeley.edu/result.php?resultid=8226545671 https://setiathome.berkeley.edu/result.php?resultid=8226545679 https://setiathome.berkeley.edu/result.php?resultid=8226545233 https://setiathome.berkeley.edu/result.php?resultid=8226545289 https://setiathome.berkeley.edu/result.php?resultid=8226545586 https://setiathome.berkeley.edu/result.php?resultid=8226545594 https://setiathome.berkeley.edu/result.php?resultid=8226545596 https://setiathome.berkeley.edu/result.php?resultid=8226545599 https://setiathome.berkeley.edu/result.php?resultid=8226545603 https://setiathome.berkeley.edu/result.php?resultid=8226545604 https://setiathome.berkeley.edu/result.php?resultid=8226545609 Those that someone else completed reported Completed, waiting for validation, or two others produce a valid result using some other application version. I'm using the 441.12 driver. I just got a notice that the 441.20 driver is available (released today), and am now downloading it. The last few of these stopped counting progress at 0.603%, except the one now running at 0.605%. How do I tell if any of these were Arecibo VHAR workunits? |

The problem has been seen on tasks with Angle Range as low as 1.1. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Has anybody reported this problem to NVIDIA??? If not, they need to do so immediately. |

Or use the SAH app that works. Or don’t use Windows 10. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

I believe others here when they say it's been reported to NVIDIA. or that the latest drivers haven't solved the problem. I did try some of the later 436.xx drivers which didn't work. so I'm back to 431.60 checking the release notes for the last couple of drivers. I don't see it as a known open issue so I'm not certain. Nvidia could just try and patch it on the quiet. |

Yes, somewhere buried in the attic of this forum is a post that actually defines what range constitutes VLAR and VHAR and a proposal of what should probably be called medium angle range. I didn't have time to go search for it earlier. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

NVIDIA released 441.20 drivers today. I tested them, and they still have the "SETI OpenCL SoG VHAR on Windows 10" problems: Maxwell: > Tasks crash with error. >ERROR: OpenCL kernel/call 'clEnqueueMapBuffer(gpu_GPUState)' call failed (-36) in file ..\analyzeFuncs.cpp near line 1995. Pascal/Turing: > Tasks run indefinitely with no load on the GPU. 431.60 are the last drivers that work correctly for those specific SETI tasks on Windows 10. NVIDIA is aware, and per NVIDIA, we must continue to be patient for a driver version that includes a fix. |

Another VHAR failed with 441.12 https://setiathome.berkeley.edu/result.php?resultid=8226545610 I installed 441.20 without restarting Windows; the next task ran in a different slot, but had the same problem. Also progress froze at 0.605%. The VHAR that failed with 441.20 https://setiathome.berkeley.edu/result.php?resultid=8226545584 Two things to consider for this type of problem: Allow sorting all tasks or only the error tasks by timestamp of completion. Allow telling the server don't send me any VHAR tasks. I just reinstalled 431.60. Tasks appear to be completing normally, even if VHAR. Could .vhar be inserted the names of VHAR tasks? Also .mar for medium angle range, if that is defined? |

Found the post and it was from HAL9000. https://setiathome.berkeley.edu/forum_thread.php?id=79990&postid=1805455 VHARs >1.0 (aka "Shorties") And from Richard's post. https://setiathome.berkeley.edu/forum_thread.php?id=79990&postid=1805543 Technically, VLAR was used to denote AR 0.05 and below, and VHAR for AR 1.1275 and above. When GPUs came along, we extended VLAR to a somewhat arbitrary AR 0.12 Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

I remember at one time the project servers were setup to NOT send a certain type of task to Nvidia GPUs. I believe it was Arecibo VLARs. I’d assume something like that could be implemented again, only for VHARs this time. Just set it up to not send any to those on SoG and on Windows 10.

Same problems here, like others, glad I found this thread. Was not sure what the cause was. I will try reverting the drivers now. |

Yup, my daily credits have dropped by 50% since updating my driver. Can't revert, I need the latest for my main tasks, SETI is just for idle time. Let's hope someone comes up with a fix soon. Thanks for this thread, really had me scratching my head wondering what was broken! |

I just installed the NVidia Studio Driver version 441.28 . I'll let you know if my SETI performance is restored. |
