Here at Seti@home we've created the world's largest supercomputer, composed of all of our individual desktops and laptops. My question is: How many Seti@home units do we have in storage to work through? Putting aside the fact that the Seti people constantly create more units from new telescope data, I'm just trying to figure out if our "supercomputer" is going to blow through them really quick, or, conversely, if the project is tons bigger than the "supercomputer" can handle. I know LHC often blows through its queue list in a week or less. ----- |

The WU's often get repeated over and over again just to make sure nothing was missed. I think!! if I'm wrong im sure someone will let me know Join us in Chat (see the forum) Click the Sig Join UBT |

Here at Seti@home we've created the world's largest supercomputer, composed of all of our individual desktops and laptops. SetiBOINC is far more efficient than Seti Classic when it comes to plowing through data. When Seti Classic shuts down for good and a majority of those users find their way here, it's quite likely that SetiBOINC will be out of work on a regular basis. Currently they're working on a Seti "Enhanced" client that does a much more detailed analysis of the radio data, so that may help...but only time will tell. You will be assimilated...bunghole! |

Repeating WUs over and over was a SETI Classic thingy. i) Because there was so much cheating, work need to be run many times. ii) So as not to run out of work WUs were just re-issued. As I understand it, on BOINC/SETI we can process work faster than it can be recorded. That is with the current application, the next version of SETI will significantly increase the 'depth' of the analysis and will take much longer to process. On top of that, BOINC has been specifically designed with the principal of there being no work sometimes, hence the multi-project capabilities. |

BOINC/SETI isn't any more efficient. Ignoring the optimized clients that others have produced, the actual SETI science application is the same for both classic and new. If the source were available for SETI Classic and anyone could be bothered to re-compile it, it would run just as fast. |

I was referring to the way in which SetiBOINC only sends out 4 copies of each result, whereas Seti Classic can send out dozens. This means that the data will be processed more quickly than with classic. You will be assimilated...bunghole! |

Sorry... duplicate post |

SETI Enhanced = Astropulse Actually, no it's not. http://setiathome.ssl.berkeley.edu/forum_thread.php?id=15779#124200 Astropulse is a separate project, the Seti Enhanced client simply does more science than the original one. You will be assimilated...bunghole! |

Then more accuratly, "more data will be processed, but at the same speed" ;) |
Borgholio Send message Joined: 2 Aug 99 Posts: 654 Credit: 18,623,738 RAC: 45 |
If more data is processed at the same speed, the the entire operation is going faster. Thus, my original statement stands. :) You will be assimilated...bunghole! |

SETI Enhanced = Astropulse See I said someone would correct me if i was wrong. Cheers for the correction Im only on dial up at the moment and it takes a while to get around the forums to read posts, its like swimmin in treacle Join us in Chat (see the forum) Click the Sig Join UBT |

SETI Enhanced = Astropulse Treacle? Is that like molasses or something? :) You will be assimilated...bunghole! |

Definitions of Treacle on the Web: * a pale cane syrup * an expression that is excessively sweet and sentimental wordnet.princeton.edu/perl/webwn * A dark viscous sugar syrup. thefoody.com/glossary/glossaryt.html * A syrup containing cane molasses, which darkens it and gives it a special flavour. www.irish-sugar.ie/noframes/nf-pages/nf-gloss/nf-gloss.htm * A medicinal compound of many ingredients, originally a salve, considered particularly useful against snakebites and other poisons. www.mindmagi.demon.co.uk/Bacon/reference/glossary.htm * the residue from the second stage of crystallization of raw sugar, less bitter and viscous than molasses. an edible treacle is produced by filtering dilute molasses through cloth and charcoal. www.mawer.clara.net/glossary.html * [I've treacle and toffee]: The mundane meaning is simply molasses. But the word has an older and more romantic meaning: an antidote for the bite of wild beasts. www.umgass.org/shows/pinafore/jargon.html Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws.

SETI Enhanced = Astropulse I believe that current plan is a separate science application under S@H rather than a separate project. BOINC WIKI |
