I'm taking the server down tonight (and probably most of the tomorrow). I've made some big changes in the assimilator and validator which should help me implement new features and debug them in the future (mainly I rewrote them in Java so I don't have to worry about memory leaks or segmentation faults). I'll be debugging them over the next couple days so expect some outages. Most notably, validation will be much stricter now; considering even though I've asked nicely we still see a lot of people trying to scam the system (scripts and single precision GPU clients for example). It's kind of sad that a few bad users have to ruin things for everyone (and make our work that much more difficult), but I guess thats the way things have to be. On another note, we've had two papers accepted recently, one to the Distributed Applications and Interoperable Systems (DAIS 2010) conference (http://discotec.project.cwi.nl/index.php/DAIS:Main), and another to the World Congress on Evolutionary Computation (CEC 2010) http://www.wcci2010.org/topics/ieee-cec-2010. I'll be making these available after the validator/assimilator upgrades. ![]() |

It's good to hear you're on top of things - I hope BOINC gives you enough capabilities to deal with the scammers. Will these changes affect the distribution of the anonymous platform apps? For instance, will new versions need to be validated before being allowed, assuming you have the capability to enforce validation? |

For instance, will new versions need to be validated before being allowed, assuming you have the capability to enforce validation? Once the new validator gets up and going validation will work as follows: Any result that could potentially improve one of our searches will be validated (with a quorum of 2 or 3). Previously, any result that wouldn't improve our searches we ignored. I'll be validating 50 - 100% of these for the next couple weeks so everyones error rate gets update correctly. After everyone's error rate has leveled out, I'll drop the validation done on these workunits to whatever % the error rate of host returning the result is (minimum 10%). So we'll still be validating every potentially good result, but we'll be using BOINC's adaptive validation for everything else. ![]() |

I just got two very different credit per hour rates. The const_v2 searches are considerably faster than const_v3, but yield the same credit. Are you going to be holding a second set of statistics for people who abort longer-running tasks? |

Is the new validator still being tweaked, seeing as a lot of us are getting work marked as invalid. ![]() |

I don't know what's wrong Travis, but I'm not getting anything to work on. You have to ask in order to receive. I guess your machine is paying off debt owed to SETI at this time. F. ![]() |

I don't know what's wrong Travis, but I'm not getting anything to work on. The problem is that you keep hitting the damn update button...stop doing that. A user request (update) will never trigger a work fetch and will only increase the backoff time. You're makeing it even worse doing that. ![]() Join Support science! Joinc Team BOINC United now! |

How is that suppose to work in regard to this -> http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=1640 ??? Besides that, what's the problem with those results ? When will it be fixed ? ![]() Join Support science! Joinc Team BOINC United now! |

The new validator should fix that (along with the new applications we're going to be releasing this week). |

Travis, I take it the periodic feeder outage is something that will continue until the combination of new hardware and the new application are in place. Yeah :( But we're working hard on getting those new applications up and running. I should have the validator for milkyway3 going and sending out workunits tonight. I have the OSX binaries compiled, and we also have CUDA linux. Anthony is working on the windows versions as we speak. We'll probably make the swap within the week *fingers crossed* ![]() |

OK -- I figure I'll be on the lookout from this side. Just figured to 'set expectations' at the right level for now.
