it does since reboot. And nothing is going to stop the cheap shots. It will not stop me from sharing what could be useful information. Maybe not. The timing was suspicious. But that is a stretch. Depending on where the units landed, might be no cause for alarm. If others are having vanishing units.. Could be cause for concern. Janice |

Total cash donations since 1 June 2008 have been $ 217770.11 so about half that annually. It amounts to about 1/5 of a reasonable budget, so perhaps we should consider anything more than 20% uptime a testament to the skills and dedication of project staff.Joe I guess I missed the "cash" part I meant no slight was just pointing out It's not just the cash donations that keep this going I've been here since the classic days and nothing surprises me or troubles me Sure things could be better .. where couldn't they be It's just a shame we can't all respect each other's opinions and not resort to slamming people we disagree with On another note something I've thought about for a while This is all about distributed computing Could not something be done to distribute the load of handling the "seti@home" project via distribution instead of all being done in a server room at berkley splitting verifications & creating the master data base over several volunteers computers on the internet |

it does since reboot. Same. While I do get frustrated with people making demands and claiming rights they don't have, I don't pretend for one moment that there aren't issues to be resolved - and bugs too. Given that the scheduling server has been off for most of the day, it's fairly unlikely to be anything server-side. Unless of course it happened in the brief window when the project was up and you just didn't notice at the time. That's plausible (I've had crunchers sat idle for a week because I didn't notice stuff). Maybe the logs (see BOINC data directory) might reveal something useful.

It seems to me that this has been proposed before, but it was determined at the time that any benefit in doing so would be lost in the complexities of transferring data back and forth between a master database and external hosts, verifying integrity of data, maintaining scientific integrity of same, etc., etc., etc..

This problem of distributed validation is being researched generally by a few universities... but to my knowledge (as of late last year when I was in research), there is no solution that works at the scale of SETI@Home. IOW, no solution any time soon. |

This. Given that the source data is in 50GB 'blobs', the internet isn't up to distributing them. Peer-to-peer distribution of workunits might help with download bandwidth, but also opens up a whole can of network issue worms - not to mention security concerns. Besides, all the results have to get back to Berkeley somehow eventually to be validated, assimilated, and NTPCkr'd over (assuming that gets to operational status in due course). So the databases at least end up just as big as they are now. Stats site - http://www.teamocuk.co.uk - still alive and (just about) kicking. |

Well it wasn't really that long ago that boinc wasn't possible either as home computers get better & better thing theat wern't possible now are Maybe getting the message boards off local servers ? or just a raid array of disk space accross the internet Now there's something |

Update: Our upload server disk array crashed last night, but has been recovered. However, the project will remain down until we process a large backlog of results. Looks like a resync did the trick. Clearing the pipes before opening up for more punishment seems like a sound idea. Stats site - http://www.teamocuk.co.uk - still alive and (just about) kicking. |

It's a problem that has been discussed many times, probably too many. In the end all the data has to though one fairly small connection and that makes it virtually impossible. Even if the rest of the resources were provided gratis. |

Ok as per usual the nay sayers have the majority It's always easier to say WHY NOT than to come up with the solutions I'm too old to fight any more Just remember yesterdays dreams are todays reality |

It's a problem that has been discussed many times, probably too many. In the end all the data has to though one fairly small connection and that makes it virtually impossible. Even if the rest of the resources were provided gratis. The next step is to make the quorum and validation distributed. Then, the SETI@Home servers can simply poll for the result via DHT mechanism. The only disadvantage that is certain is the increased latency between work distribution and storing the canonical result. However, no intermediate storage is needed server-side (no upload server). I expect we'll see this architecture available as soon as 3-5 years from now, or longer if no one pursues any applications. It's a waste to discuss changing the SETI@Home architecture until technology and/or resources are greatly improved. But if anyone really wants to beat the dead horse some more, I suggest starting a new thread instead of filling this one up. |

As I said it has been discussed many times and there has been a even greater number of suggestions, all of which have been rejected, mainly by people who have a lot more knowledge that I on the subject. Some of the knowledgeable were Ned and Ozzfan, who have retired. On of the reasons being because they got tired of repeating explanations to people who wouldn't look to see if there were any previous posts on the subject. |

thank YOU O WIZARD FOR YOUR WORDS OF WISDOM I'm out of here If i wanted trolls & bs I'd turn my time machine back to the 60's These forum threads are not invitations to flame other posters or post what you think you know It's apparent nothing useful can be accomplished BYE |

I really don't see how WinterKnight was being a troll, and throwing BS around. He simply stated a fact, and why those who have a great knowledge of things going on around here have left. Nothing of that was being a troll, or feeding BS. And maybe heeding to your own words, these forums aren't an invitation to flame other posters, just as you said yourself. Good day sir. |

thank YOU O WIZARD FOR YOUR WORDS OF WISDOM Everyone here have dreams of what could be. We all must live under the constraints of limited time, limited personel, limited funds for Boinc and Seti. It is what it is. Boinc....Boinc....Boinc....Boinc.... |

setizens. lets keep this a positive place. we are all concerned about the current problems, getting angry with one another solves absolutely nothing. if your frustration level is at a high point, consider cutting your computers off for awhile. at least until the mess is demessified. you'll save money on your next power bill also. |

setizens. Well, I usually find the 'off' switch to be a pretty good solution, when things can't upload and downloads are not happening. I also acknowledge that it is unreasonable to expect a project as large as this one, with resources limited in the way they are, to be 100% functional 24/7 all year. Is that called, being realistic (no connection to Tandy....lol)? Don't take life too seriously, as you'll never come out of it alive! |

LOL I'm right there with ya, although I crunch for more than 1 project. My computers stay toasty warm regardless of what happens on any of the projects. My laptop I'm attached to 17, 3 of which rarely have work, LHC, Pirates, and Orbit@home. My desktop is connected to pretty much everything in my sig. So 1 goes down, start another. :-) No problems EVER here. LOL |
