Let's just say you take three numbers: Number of work units. Cpu time (Machine type)Average unit Time Average work unit time individual=CPU Time/Number of work units Chance person cheats=1-Individual Avg WU time/Average WU Time |

Let's just say you take three numbers: I am dense sometimes..are you saying it IS easy to cheat under Classic or is NOT easy to cheat under Classic? |

Let's just say you take three numbers: It was said it was easy to cheat by just crunching LAR wu's. Well if their average time was 30 minutes when the average time for their type computer is 2 hours 30 minutes. 1-1/5=.8 You could probably state that there was more than an 80% chance they are skimming their work units. |

Let's just say you take three numbers: Okay but there is at least one more way people in Classic cheated...they would crunch a unit, any unit, to around 90% or so, then just before it finished, stop crunching and copy the whole directory to another place on the hard drive, come back and finish the unit. Then copy that directory back into the Seti directory, overwriting it with the unit that was crunched to the 90% or so, then finish the SAME unit again and again and again and again and, and, and, and, etc. The ONLY way to catch them would be for someone at Berkeley to notice that their time to finish a work unit had SUDDENLY dropped by a HUGE amount. But even then if they had upgraded their computer to a new SUPER FAST computer it would be VERY hard to prove. Berkeley would have to grab each workunit returned and analyze it for it name and then compare it against the next unit processed. IF the person were smart they would have a handfull of units that they could then return that way and without some investigation and concerted effort on the Berkeley personell it would be difficult to prove. FOR THE RECORD let me state here and now I HAVE NEVER CHEATED AND NEVER WILL!!!! I just KNOW that people have and some of the ways it could have been done. |
