Are there any old tapes that can be split to give AP wu's. Any plan in the pipeline to do this? |

AP is not finished. It just needs more effort doing the MB tasks so that new data can be added to the splitter queue. They only get about one AP task for every 40 MB tasks. The old data could be used for AP tasks but it needs a good s/ware only radar blanking program to be finished off and tested before that can happen. AFAIK that process is in progress. |

And if the SERENDIP crew currently working at Arecibo can fix the broken data recorder, then new data will be available and you can postpone your retirement indefinitely (see message 903751 in Technical News). And if they can't fix it, we can all retire, because there won't be any new MB work either. |

At Einstein@home i regularly get Arecibo Binary Pulsar Search units. Maybe there are less of us crunchers and we still get Arecibo data. Tullio |

And maybe Einstein's data doesn't come from SETI's private data recorder? So far as I can tell, Einstein uses the primary data recorded by the PALFA consortium: SETI eavesdrops on every ALFA-antenna observation, and records its own data separately on its own (currently defunct) recorder. |

Also, lest we forget that a lot of AP units expire and have to be re-sent. So although the current queue is empty, data will be re-sent because it expired on the 1st pass. Keep the faith! :) I have a Quad Xeon box dedicated to only AP |

Is enough for me too with no AP WU's to crunch I think is time to shutdown my farm. The average RAC with MB WU's is to low (1:2,6 in my farm) my actual RAC is 21000 this mean my RAC will drop to 7-8000 credits. I'm unhappy after more than 6 years of crunching, but the electric energy used for this maybe can find a better way to be used. |

Like so many things when you get a bunch of people together in a forum like this, someone will see something and extrapolate it well beyond the valley of good taste. At the moment, we're out of Astropulse. One reason, which has been beaten to death on other threads, is an issue which caused the servers to run low on Multibeam, and distribute Astropulse because that's what they had. I believe I read that was corrected, but waiting is. That's nothing at all like "Astropulse is finished." Then there is the question of RAC. RAC rises and falls, depending on many factors. Aside from the occasional comment from someone saying "Nice RAC" it doesn't mean anything. So, set your preferences to prefer Astropulse (as I have) but to take whatever is available if there isn't any. Use the Lunatics installer that makes optimize apps painless, and remember: SETI always promised that there would be times with no work. When you complain there is no work, you're berating them for keeping that promise. |

I guess i dont get it. I have been crunching for 10 years. It has never been about the credit. Its been about, maybe it might be me who finds the WOW signal. NO work oh well i crunch Milkyway too. Im doing something usefull with my spare time and my computer. [/quote] Old James |

....It has never been about the credit. Its been about, maybe it might be me who finds the WOW signal. ..... I agree with you James ... but there is work. 120ish Tapes currently splitting seti@home enhanced work units! Credits schmedits ... Ya we all like em ... Its about what we are ALL looking for isn't it??? ...just my 2 cents... Edit 1 Oops. Maybe I put my foot in my mouth! Data Distribution State SETI@home # Astropulse # As of* Results ready to send 48 0 4m Current result creation rate NULL/sec NULL/sec 35m Edit 2 This is better; SETI@home Current result creation rate 23.6522/sec Rick ************************** |

I got a astro pulse yesterday!..I run a dual core and set it at %100..And still say's it gonna take 393 hours... Well i run a dual core AMD(The Best)..At 2.6 ghz x2. With 3gb ram Nvidia 8600 gt video card.. So what is the big deal about astro pulse's?And why is it takng so long? Oh btw..I run 2 pc's with seti..For 6 total.But use other's for game's and game server's.. Thinking about running einstein also |

So what is the big deal about astro pulse's?And why is it takng so long? Astropulse is searching for broadband signals, not narrowband signals (that's what Multibeam does). It follows that the work units are longer (in time) and wider (in frequency) and the search being done just takes a lot more math. I don't know why it's a big deal, either way. |

Proof lol..now at 352 hour's.. BOINC's estimate is based on how long your host has been taking on S@H Enhanced work. That's doubly unreliable for forecasting AP runtime because much of your Enhanced work is using the CUDA app. Here's how to get a better estimate: Elapsed: 15:53:46 (57226 seconds) Progress: 9.887% 57226/0.09887 = 578800 seconds total runtime 578800 - 57226 = 521574 to go, about 144 hours 53 minutes.

(15°53'46" X 100 % )/ 9.887 % => 160°46'40" Ps: calc CASIO Fx-92 :) SETI@Home Informational message -9 result_overflow with a general handicap of 80% and it makes much d' efforts for the community and s' expimer, thank you d' to be understanding. |

(15°53'46" X 100 % )/ 9.887 % => 160°46'40" Yes, that's 578800 seconds, but you have to subtract 15h53m46s to get the time to completion; and that's "about 144 hours 53 minutes" as Joe said. |
