http://setiathome.berkeley.edu/show_host_detail.php?hostid=1094597 This shows that his WUs ALL take only a tiny CPU, yet he is contributing these bogus results, along with enough folks that put in real results, that he is getting full credit, with out doing the work..?? |

Looks like a bad benchmark? Or a verrrrry fast cpu...... |

http://setiathome.berkeley.edu/show_host_detail.php?hostid=1094597 It might just be a problem with his host reporting the correct CPU time and claiming enough credits. His daily output does not seem to indicate that he is cheating unless his computer is off most of the time. |

http://setiathome.berkeley.edu/show_host_detail.php?hostid=1094597 I can't say, but I took a loot on some of his results and they are all valid! So they must be OK, even he claim very little credit for them! "I'm trying to maintain a shred of dignity in this world." - Me |

That's an odd one alright... The results are valid though so he's not cheating in a traditional sense.... The XML may have been edited to report incorrect benchmarks... but why you would do that i don't know.. unless you were to inrease the number to pushup your claimed credit. CAn the Wu reports also be edited to report incorrect CPU time etc? odd... Wanna visit BOINC Synergy? Click my stats! Join BOINC Synergy Team |

I note that he's using CC 4.43 amd application version 4.02!! Plus 5,026 SETI Classic Units |

Good spot! 4.02 suggests SETI Beta application... but can it be that? how could that return valid results.... for the current live project... unless he has an optimised client which he has named 4.02 Wanna visit BOINC Synergy? Click my stats! Join BOINC Synergy Team |

4.02 is an Optimized Application used by US Seti Beta testers. I be he put it in the wrong folder. (I.E setiathome, instead of SetiathomeBeta.) the 4.02 application doubles the search sensitivity of the data. |

yeah sounds about right, but how could that return valid results for the live (non beta) project? Wanna visit BOINC Synergy? Click my stats! Join BOINC Synergy Team |

I'm off to find out if "Sandrews" is a Beta tester or not. I'll create thread in the appropriate location to try to get his attention. BRB |

I didn't find that name out of the 194 Beta testers so I started a thread in NC so hopefully he'll see it. Good catch Don Erway |

Perhaps put the same thread in the BETA project site? he's on BOINC@AUSTRALIA team... but their forums dont seem to work! Wanna visit BOINC Synergy? Click my stats! Join BOINC Synergy Team |

Is it not a seperate account? I wonder if he found a way to hack the source and return a result that fools the validator, without doing the work. |

I suspect he went to the Marisan website and just picked the wrong one. Unless he's getting his 500 claimed credit he's really wasting time for no extra credit. the 4.02 WUs take more than 5 hours on my AMD 64 Athlon 3700+ with the optimized client, I've heard of them taking 29 hours for other participants. that's gotta hurt. I don't think he's a beta tester but will post there also. The best solution would be for Berkeley to Email him. tony |

SETI Beta is a separate BOINC project so the applications etc should be kept apart. What Mmciasto is suggesting is that perhaps he installed the BETA optimised client rather than live project optimised client. If that is the case then it is a fair enough mistake to make, however there is still a question as to how the validator could validate that results against the normal SETI app. The science is very different in the 2 (AFAIK) so it should not get through... I suppose though that there is no point speculating until we know exactly what is going on... he could be cheating also but only claiming less than 0.1 credit? what would be the point?!!

Version 4.02 is the current application version for SETI on linux machines. So I doubt anything is wrong with that. It is more likely a problem with the time-keeping in his Boinc CC and/or the SETI application. Unless you know a machine fast enough to crunch normal results in less than 10 min. |

What I'm suggesting is that he acquired the wrong optimized APPLICATION file and installed it in the setiathome directory. He may have acquired it from marisan.nl, but that's unimportant. I don't know enough to know if the results would be compatible. I believe the WU are the same for both projects, but Beta is doubling the sensitivity of the search and possibly later on be crunching the new "Astropulse" WUs. |

I do notice that all of his times are a fraction of what the other valid results are. His computer is listed as a Pentium Pro (very old). It will be interesting to find out what is really happening here. Jim What I'm suggesting is that he acquired the wrong optimized APPLICATION file and installed it in the setiathome directory.

it is the time reporting that is wrong. you notice that it takes about a day to crunch each wu. the app should be fine since he is running linux. since the PC is listed as GenuineIntel Pentium Pro, the benchmarks appear in the correct ballpark for a non crippled 200MHz cpu. i have a celeron 500 that benches a little lower in win98 S@h Berkeley's Staff Friends Club |

Seems I'm the dumb A**, I'll remove the other threads. sorry, it appears it is a linux 4.02 version with a 4.43 client. Don't know why he's only taking 527 seconds to complete the WUs unless it's an internal clock problem or maybe just clock time since last checkpoint. Sorry tony |
