Host I listed that machine earlier as its 1 of a few that are making a mess of things in my pendings. ;) Cheers. |

i just looked at my own tasks, and I have 4 of these -12 errors on my laptop (Gtx 8800M)- I remember these errors happening and all of them happened when my GPU was overloaded because I have SETI crunching enabled 24/7 on both CPUs and GPU, and if I load up a video on youtube or media player etc.. without suspending the BOINC usage first, that happens every now and then. |

That is probably coincidence. [aka supersticious pidgeon*] There was a condition where not enough memory for tasks could lead to false -12 instead of triggering the 'not enough mem' functions [CPU fallback for stock and up to x38g, task wait for x41g and later] but that got ironed out somewhere between x41g and x41x. In general -12 are 'too may triplets found' or something like two triplets too close together iirc. High occurance in stock, low occurrence in x41g and eliminated in x41x. * the event is random, but you notice those instances most when it happens in conjuction with something else. the belief in connection gets reinforced, the instances when it's not connected are either overlooked or seen as exceptions from a rule. Fascinating thing, Psychology. I'm not the Pope. I don't speak Ex Cathedra! |

Further to my post below I found these as well Host 6112618 Host 4202271 Host 6257665 Pending 3257 5041 65 Valid 1 102 8 Invalid 397 353 3 Error 44 12 24 All these are in my pending as inconsistants, with another wingman, having to redo the work. Why don't people check their results periodically, to see if they are throwing out crap results, and take action if they are. I agree with the comments, below, aand would go further, and blacklist those who are consistantly, throwing out erroneous results. We all have the occasional bum result, but the majority of us do not have the large number quoted above, and in my previous post. |

Here's another one: anonymous host 3378825. It has a small number of valid tasks, quite a few invalid tasks, plus a boatload of pending inconclusives. And it's getting bunches of new work. |

i just spent some time looking through a lot of the tasks that my computers have completed and seeing how the various wingmen are faring, and i was suprised to see how many of the wingmen's systems are throwing out hundreds of invalid and errored tasks. i sent private messages to all of the non anonymous wingmen to give them a heads up about their systems. i suggest other people do the same. but we still need a permanent solution for alerting or blocking all of those anonymous crunchers out there.. |

I still think it's time for server-side intervention. Others have mentioned the same thing.. If someone out there had their heart set on screwing with our DC project, they could setup two or more PC's in the same way to throw errors on both and reinforce tons of bad validated results. This is not cool. there needs to be an error quota. If you screw up over 50% of any type of given task, you should not get any more of that task type without getting your stuff fixed and contacting us here to get your account reactivated. #resist |

I still think it's time for server-side intervention. exactly. i'm relatively new around here so i don't know the answer, but is there somebody this can be addressed to? has anybody done that recently? some of us spend a lot of time & money on this project (and other BOINC projects) and really believe in the work we are doing here and want to see that the integrity of this project isn't in jeopardy! |

I still think it's time for server-side intervention. Something should be done soon or a lot of work of mine will likely be lost to being errored out wrongly by these rogue machines plus my inconclusive pendings are still increasing at a bad rate. Cheers. |

I did a bit of homework today to find out how many machines are mucking my end of things up (and many others to I bet) so here they are, Computer 1334363 Computer 2699082 Computer 3378825 Computer 3440890 Computer 5007852 Computer 5236541 Computer 5292089 Computer 5345364 Computer 5461131 Computer 5485240 Computer 5542882 Computer 5762247 Computer 5874840 Computer 5889577 Computer 5927348 Computer 5935169 Computer 5967897 Computer 6126443 Computer 6148459 Computer 6229518 Computer 6247292 Computer 6249179 Computer 6253461 Computer 6256705 Computer 6271384 Computer 6283429 Computer 6318737 Computer 6365602 Computer 6401198 Computer 6441935 Computer 6469701 Computer 6568123 Computer 6586696 Computer 6589662 Computer 6633670 Computer 6640112 Computer 6643594 Computer 6643620 Computer 6650172 Computer 6650230 Computer 6651362, and I bet that there would be many others besides them but the bigger question is, what are these doing to the load on the databases?

I did a bit of homework today to find out how many machines are mucking my end of things up (and many others to I bet) so here they are, Even thought they are throwing out mostly errors they are still chewing though less tasks per day then several of the top machines. I imagine the global errors or invalid tasks per day would be something like 50,000-100,000 per day. However with around 2 million being returned a day it isn't that much.

Two machines erroring in the same fashion will produce valids if they wing each other... So I guess it's a good thing these rogue machines give us grief as opposed to working silently as a team.. #resist |

The overall effect seems to be that on average there are about 2.2 results for each MB WU: Workunits waiting for db purging 620,658 0 0m Results waiting for db purging 1,345,459 37 0m The extra results of course extend the duration of the database and storage impact, so it's more than the indicated 10%. When there are stats for AP, that ratio is often higher. Joe |

The overall effect seems to be that on average there are about 2.2 results for each MB WU: Resulting in extra NET-Traffic, DataBase strain, this >10% is 10% too much and probably even higher, as Joe stated. I see more and more results requiering a 3rd wingman. Is it the quota-system unable to limit the amount of work of those hosts? |

...That's a nasty one. I just noticed that my pending list keeps growing and I found a few pages of inconclusives, all with this host as wingman. Why is it fetching workunits for cuda/cuda23 when there's no GPU shown on its host details page? (stderr says GTX 280 and GTX 295) |

...That's a nasty one. Its last work fetch was about 31 hours ago, I judge the user has recognized the problem and either told BOINC not to use it or removed it completely. Joe |

Sad though this is (to the extent it makes a complete mockery of our efforts to produce good results), and given that the project has the capacity to black-list hosts should they want to, I can only assume that the impact of these hosts is considered largely insignificant. Either that, or the project just don't want to get into the business of micro managing individual hosts..... The trouble with the quota system as it is, is that it doesn't really protect against invalids - as they don't materialise until quorum cannot be reached (by which time, a rogue host has downloaded another 1,000 tasks). Fixing that would alleviate a lot of the issues.... |
