So they results are identical. Do differencies in my result too big? And why result status not invalid in this case but "can not validate" one ? |

The status of your result changed to validate error. MW calculations and results need double precision. Your stream_only_likelihood seems ok for cross platform comparison, but background_likelihood and search_likelihood are only identical up to the 4th decimal digit which is far from what is needed. The validator decided your result needed a second one to compare against and the WU was sent out again a minute later; this was repeated until 2 results did match within the allowed difference. |

Why task was replicated before my host (first one) reached deadline ? And why two other hosts agree with result w/o taking into account result of my host. My host did not recive credit for work done and done in time. Why so ? It was replicated after your host returned it's result (and the validator apparently didn't like it so much). 5:43:03 UTC: your host reported it's result 5:43:10 UTC: _1 created (7 seconds after your report) 5:44:14 UTC: _1 send out ... I think there's nothing unusual with that. |

Well, maybe the problem is just in bad translation. I saw status "Ошибка проверки", what I think should mean "can't validate", not "invalid result". How to disable this auto-translation? I prefer to see task status in original form... |

Well, maybe the problem is just in bad translation. The status was IIRC "validate error", so "can't validate" is pretty good translation. I don't know why, but here on Milkyway the usual "marked as invalid" status seem not to be in use. You can change the language here, it's valid for all Milkyway pages (until you delete the cookie or until it expires, than you have to set it again). And why minimal quorun here 2 and only 1 task was validated? Hmm... good question, until not so long time ago minimum quorum was 1 at the begining and was increased to 2 only if the result was inconclusive. Well, as long as it works... |
