These BLC 35s are bad news, most of them are Instant Overflows. The Results received in last hour is already up to 205,271 and I only have One machine running them so far. Once other machines start running them I believe we will be constantly Out of Work, https://setiathome.berkeley.edu/results.php?hostid=6796479&offset=1120 I seem to be getting a large number of stuck Uploads as well... |

Yep. 90% or more of the Blc35 tasks are noise bombs. This is gonna add to the havoc ... Stephen :( |

I see they added some old Arecibo files to the splitters in an attempt to slow down the return rate from all the noise bombs. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Now the Server isn't responding. One machine's cache is down 50% and can't contact the Server. Naturally the Results Received and RTS is showing the change, it appears no one can contact the Server.... |

Yep, every host in scheduler backoff due to "internal server error". Can't report work and caches falling. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Able to report now, at least. Not giving out work yet, though. |

Well here is a few numbers to keep in mind Results out in the field - 7,536,318 Results returned and awaiting validation - 7,240,993 First time this year I have seen the returns past 7 million. Results received in last hour - 195,093 Cheers |

Yes, I'm seeing shorties (VHAR) now from 27au10ad. I also saw the noise bombs (overflows) earlier from BLC35. Neither of those are going to help our bad drivers and bad cards. Eric put in a draconian attempt to try and weed those out yesterday: Hopefully final validation mod to reduce bad results from failing GPUs If 1 of 2 is overflow, quorum is increased to 3 If 1 of 3 is overflow, results are validated. If 2 of 2 are overflow, quorum is increased to 3. If 2 of 3 are overflow, quorum is increased to 4 If 3 of 3 are overflow, results are validated. 4 results are always validated.so expect lots of resends, too. |

If 3 of 3 are overflow, results are validated. That is a bug. If first two are ATI graphics cards, which will produce similar bad results, it doesn't matter what the third result is processed on, if it also -9's then the two ATI cards will agree and the correct third result will receive an "invalid". See https://setiathome.berkeley.edu/forum_thread.php?id=84508&postid=2026843#2026843 I expect there to be many of them in this batch of blc35.... tasks |

I think we should monitor for a while. If anyone notices this case in the future, please post a link and we can examine. I think the three would still have to be 'weakly similar', so if the early overflow signals were of a completely different type, that could (should?) be flagged as 'invalid'.If 3 of 3 are overflow, results are validated. |

IIRC in the case quoted the results were, 7 pulses & 23 triplets Vs 30 triplets |
