Out of the blue today, a bunch of GPU WU's prefixed with "de_s11_3s_free_6" are rejected by the server as invalid. They all appeared to run to completion in a normal amount of time. The vast majority of the other WU's of the same family seem to be running just fine. All of the "stderr out" reported for the "de_s11_3s_free_6" series look pretty much identical. Any ideas how to figure out what happened to these handful that were rejected? |

Brian, I experienced the same thing with "de_s11_3s_free_6" work units, some marked as invalid although the amount of runtime is just fine. |

Same thing on my Quad with a 5830. |

Something is messed up with the validator. I'm too seeing WUs marke as invalid... Would be nice if someone could fix that. Join Support science! Joinc Team BOINC United now! |

About 1/6 of mine, including 1 CPU WU that ran for 9.5hrs, are being rejected lately. New code reported instead of just "Invalid": "Workunit error - check skipped". |

Also seem to be getting lots of invalid results |

All my GPU's are getting some "Completed, can't validate" and "Completed, marked as invalid". non of them are overclocked. I'm not too bothered by all the Pendings as those should be OK in time but when wu's have 5 or 6 results all marked as invalid then I would hope that when the work on the validator is finished that it will check these results again. |

Its like noone cares :P It's more like you are reading the wrong thread!! Try looking at the rather active top thread in the news forum and you'll see that Travis is actually working pretty hard trying to solve these issues. Cheers, Gary. |

I looked at this thread and didn't look at my Milkyway GPU. I see I am getting the same with mainly - "Completed, validation inconclusive" or "Completed, can't validate" - as others are reporting. This can be seen here, where about half of them report "validation inconclusive". The rest, when looking at more detail are like this with multiple resends. Looks like there is a lot of marginal work being sent out, or the recent server changes have affected something that was marginal. For this rig the problem seems to have hit me with a higher rate, or mix, of these inconclusive WUs over the last 24 hours, although the problem has been about for sone time. The interesting thing is there are a significant number of WUs coming down, being crunched and returned that validate in the expected way. This suggests the problem lies with the work being sent out. Go away, I was asleep |

Today (April 5) I have counted all units done and I have aprox. 1/3 marked as invalid (160 invalid and 340 valids). All of them has lasted normal time to be processed. I have stopped to crunch in Milky for a while. |

I have stopped to crunch in Milky for a while.Over the last 10hrs, it has rejected 120 of mine. It would normally do about 400 WU's over that time period on the HD5870 so I'm getting roughly the same appalling failure rate. |

Looks like its the new Validator, its possible Tobias is still working on it. Whatever whichway, there is not much point crunching until its sorted out with the output its has been giving for the last 24 hrs, so I've gone NNT for now. EDIT : Discussion going on about this over at the News Forum, Travis is working on it, see http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=1644&nowrap=true#38053 Regards Zy |

A massive number of WUs are marked: "Completed, can't validate" The Workunit is marked: "errors: Too many total results" Nobody has a valid WU? Don't believe it. |

What does this mean: "errors: Too many success results" http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=86084176 Does that make sense at all? Edit: Here's some more "Too many success results" http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=88320323 http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=84473249 What the heck does "Too many success results" mean? |

...there is not much point crunching until its sorted out with the output its has been giving for the last 24 hrs, so I've gone NNT for now.What's NNT? Just checked the task view and MW's rejection rate now exceeds 50% of WU's run using dead-stock applications with non-overclocked hardware. I see absolutely no point in staying either. |

NNT = No New Tasks -- basically completing all taks in the queue and having other projects work (primarily Collatz for ATI GPU workstations). I expect that Travis will fix things reasonably soon unless MW needs no more work done. ...there is not much point crunching until its sorted out with the output its has been giving for the last 24 hrs, so I've gone NNT for now.What's NNT? |
