So how can we verify if the work being returned is correct, what should we look for? |

Faster applications returns incorrect results. sorry i thought in your team there where also optimized apps used made by some of your teammade. i had the user mindc in my mind. nevermind if im wrong. |

This is strange as well. I detached all boxes and the account page still shows all. Some even have work shown pending. Your boxes will be still visible on your account page even after detaching. This is normal, because you may want to review your results or re-attach later. ;-) Lovely greetings, Cori |

The way I check is to go to my MW account, click on "Computers on this account" and then click individually on the tasks (under computer ID). If you scroll to the next 20 results, and on, it will show whether the WU results are valid as the results given are quoted as successful under the title Outcome. |

I just checked mine, and they list as outcome = success, so I guess this doesn't affect everyone?!? |

Faster applications returns incorrect results. Ahh you mean about this app, it returns correct results (same as oryginal app -3.046272445362277) |

correct me if i'm wrong with minimum quorum 1 initial replication 1 all results will be valid and give points, but it doesn't mean that they are correct :) to check this you have to compare results of the same wu crunched using opt app and official app |

correct me if i'm wrong I guess you're right. ;-) Lovely greetings, Cori |

how do you crunch the same WU twice? |

Travis has a post here where I presume the usual return of success is taken as a valid result as he will have knowledge of the outcome. Otherwise none of us can know if we are successfully churning out invalid results without a wingman to compare against. I am aware the successfully returned results are being granted credit, as per the credit rules posted elsewhere. But, can we assume the results are valid when it is shown as successful and been given credit? |

Otherwise none of us can know if we are successfully churning out invalid results without a wingman to compare against. As of right now (until i've finished with the current changes to the assimilator), the only way to check if the application is spitting out the right results is to run it with some of the sample inputs given with the code, and compare the result to the stock app. If they're the same then everything is swell, otherwise the other application is incorrect. |

This is not correct. WU's are being validated as correct, even though they may be returning incorrect data. |

Travis I presume this can be done if someone was to D/L a batch of WUs and then back them up to another folder from the MW BOINC project folder. If the WUs were then allowed to crunch in the normal way with this new faster client, with the no new taske active. Then the backed up WUs were returned to the original folder and again crunched with the stock item. Would this give an OK comparison (the results would be shown on your servers). possible problem: This means reporting to the MW project the same sets of results twice. Would that cause problems at your end? |

Ok, so then exactly how would someone; sitting at their computer verify that they are returning valid and correct data? |

Beau I do not think we can from our computers. As Travis posted here about the only method to verify that good results are being churned out. |

Beau And how would one do that? There were no sample inputs given with the code. Just the same link and app that others downloaded from arizmoon.com |

Beau Yes there are, if you go to http://milkyway.cs.rpi.edu/milkyway/download/code_release/ all of these have sample input files. |

Beau Ok, I downloaded the Milkyway release .7 (I am assuming that I was supposed to download the latest one?) Now what do I do with them? Sorry--I dont mean to be a pain... Thanks |

Beau You should be able to put the milkyway executable and the other executable in the same directory with the sample inputs and run them. This would be (from where you uncompressed the files) ./milkyway/bin/test_files/ |
