Hi, I've been a long time SETI cruncher, but I'm relatively new to Rosetta. I've crunched a little bit of Rosetta while SETI was down, but now am thinking about continuing to devote to Rosetta even after SETI gets back online. - Is there a consensus on an optimized time for the length of time to allow WU's to run? I currently have it set to the default. - Are there optimized Rosetta@home applications, built for specific processors? Thanks! |

Not a bad idea :) Welcome aboard... 1/ If your pc is running 24/7, you can set the length a bit higher. A higher length, will mean less network traffic. 2/ There aren't optimized applications for Rosetta@home Member of Dutch Power Cows |

Hi Free There is no scientific benefit to changing the run-times, but longer tasks have the advantage of reduced load on the R@H servers. Bring all the power you can - it'll be put to good use, and i bet R@H will get results before S@H does! |

Hi, Thanks for the replies! I'm reading now on how the science behind Rosetta works. Interesting stuff! Sounds good. I plan on crunching 24/7 as Boinc runs as a service on my computers. I'll extend the WU time to help take some of load off the R@H servers... Thanks again! (That is cool that the R@H application is already "optimized" also.) |

I've briefly looked at the cr/hour stats on a very small sample of wus run at 3hrs vs 24hrs. it seemed to me that 24 gave a more stable result than the 3 hour ones. However, the sample was small, and it was looked at on different hosts. I've run 8 days at 3 hours, and switched last nite to 6 hours, then I'll go to 12 and finally 24 hours. I'm hoping for a similar number of samples per pref. This however will require many weeks to do. I might just dedicate a month or so to it, then give the results. Hmmm, 100 results @ 3hrs plus 100 @ 6 hrs plus 100 @ 12 hrs plus 100 @24 hours = 4500 hours or 187.5 days. Hmmm, getting a medium to large sample seems like a bad idea now. rethinking ongoing plan. |

Yeah, those would be interesting numbers when you are done! After reading a bit on the science involved here (can't say I really understand all this protein stuff yet), I'm thinking about permanently sticking with Rosetta even after SETI comes back to life. I'm such a small drop in the SETI ocean, which already has more than enough users. This protein stuff seems like it could be beneficial in the relatively near-term. E.T. may have an answer on how to cure diseases, but asking E.T. and waiting for the reply would take milleniums. :^) The Rosetta community over here is also very warm and friendly. (Not that the SETI community isn't, but it seems much more so over here.) Cheers 'n beers! |

Hi Free, I just want to welcome you to Rosetta! It's a great project with HUGE scientific and medical potential. I hope you'll stick around and help us :) |

Free, I definitely am more inspired by Rosetta@Home as well. If we can use computers to get biology to a predictive science (like chemistry is now), we could make some major advances that will improve people's lives in the near term. I think Rosetta also has more potential than Folding@Home, but I'm no expert. I think they are working to solve different problems. I think SETI@Home has too much power for what they need. Don't they have 4-5 computers crunch the same data? I would think two would be enough unless you get a discrepancy. Maybe their computing need will grow with the new multi-beam receiver; nevertheless I think medicine is more important for now. Just my opinion though. |

Hi, Me too. I think I might quit SETI. this is for a better cause. |

I think SETI@Home has too much power for what they need. Don't they have 4-5 computers crunch the same data? I would think two would be enough unless you get a discrepancy. The validation quorum was recently reduced from three results to two, and the initial replication accordingly from four to three. I don’t think the quorum was ever as high as four. |

That's still one computer that crunch for the sole purpose of making the pending credits as low as possible. In other words, roughly 33% of the computing power is used to only satisfy those, who cannot wait 1 week to get their beloved credits. That's one of the reasons why I like Rosetta. No waste in duplicate work. I know it's quite unique you don't need two computers to validate the data, but at least you should never make the initial replication larger than the quorum needed. |
