I detached and it didn't clear up most the WU's that got deleted from my system ( only appears at the moment 2 out of 20 something show client detached ) so I'm now at a loss as to what I can do to free them from my task list. I'm going to re-attach the project now and go back to crunching. Have another look now. I think it's actually the re-attach which does the trick: after all, detaching is basically saying "I don't want to talk to the SETI server again" - so the server doesn't get to hear about it. It's only when you're on speaking terms again that it can piece together the course of events. |

The Ability to select applications is now available in your Seti@Home preferences. I have opted not run AP. I may resume later if the WU are reduced in size to match S@H. In the meantime, I have one AP WU that is 54 hours into with 36 more hours to go until completion. I have another that is 7 hours into with 51 hours to go until completion. Will these two WU run until completion now that I have selected not to run AP? |

The Ability to select applications is now available in your Seti@Home preferences. Yes they should, all other things being equal. I'm pretty sure the 'preference' settings are only used when the servers are deciding what work to send you - not at any later stage in the cycle. |

Excellent! Thank you for the quick responses, Richard & Byron! |

Tonight I have a AP work unit that has stopped processing at 81.25% complete after 85 hours of work. The Processor just sits there idle. The processing clock and % complete does not advance. If I suspend processing on that WU, another work unit picks up and processes at 100% of the CPU. If I make the computer start another AP WU, it seems to process just fine. Can a work unit "go bad" and cause everyting to stop making progress? Should I just abort that AP work unit? Bruce Parker Dumfries, VA P.S. I just aborted it. Everything else seems to be working fine. |

First astropulse on my 1.1ghz machine running windows. CPU Time: 27:11:52 Percentage: 7.447% To Completion: 209:19:14 Fingers Crossed. |

I have an Q9300 4-core CPU with DG33FBC motherboard. I'm just wondering why I seem to get much less credit-points than before. Further investigation revealed that the points to CPU-time ratio is significantly better for seti@home than astropulse. Any explanation as to why? |

The credits-per-hour difference between Multibeam and Astropulse units has been hashed to death already. The Astropulse application analyzes data in a completely different way than the Multibeam application. It's another way to detect a possible non-terrestrial signal. You have three options: 1. Continue running Astropulse as-is. 2. Upgrade to the new optimized Astropulse application (see post). HIGHLY RECOMMENDED! 3. Turn off Astropulse in your online preferences.

Thanks. I suppose I'll wait for an optimized Astropulse Linux 64-bit client. |

Just curious.......what is the credit ratio right now between opti MB and opti AP? Or is the jury still out on that one?

The Astropulse application analyzes data in a completely different way than the Multibeam application. It's another way to detect a possible non-terrestrial signal. Roughly - on 45 cred MB WU's my rig could knock out about 1060 creds / core in the 13 hours that an AP WU takes with the Opti App for (currently) about 760 creds. I haven't got a mean value across the range of MB AR's. F. ![]() |

I thought the auto adjustment credit thingy was supposed to level this out....... It's been in place for long enough now, hasn't it?

[quote] The auto adjustment thingy will see far more stock MB and AP WU's and will, therefore, be far more effective at levelling those. I would expect there still to be significant difference in cr/hr between optimised MB and AP as the optimisation can't possibly provide identical performance gain. F. ![]() |

On Cruiser: Optimized Multibeam application time decrease: 33% (80 minutes versus 120 minutes) Optimized Astropulse application time decrease: 66+% (~31 hours versus ~98 hours) Technically, Cruiser still hasn't finished an all-optimized Astropulse unit yet, but previously-accurate time calculations actually place the total time at 29.35 hours. I'm just allowing a little extra leeway. In any case, I'll find out for sure in about 12 hours. I would've kept doing Astropulse units even without an optimized application. This just makes it much more attractive to more credit-conscious crunchers ... especially those running AMD-based machines. Of course, this is all dependent on whether the results will be validated. I have high confidence that they will - partially-optimized units have already validated for me.

Actually, Mark, don't forget the idea is to achieve credit parity between stock MB and AP applications. I don't think it'd ever get close to giving Stock AP the same credit/hour as Optimized MB, like most of us board lurkers had been running... |

Congratulations to the AP opti-app development team! Running the new app pushes my core temps slightly higher (almost one full degree C) than the MB opti-apps. I guess this means the new AP app is pushing more science/cycle. Wow, that is some incredibly tight code you've all written for this one. Really impressive. Bob |

I am using the Seti@home optimized, and I need someone to re post the appinfo.xml file. I downloaded the new Astropulse Linux x86_64(4.36) and updated the appinfo.xml to match the file location for the new astropulse and updated the version number, but then when the next astropulse WU came along, Boinc trashed the one it started and all the other ones that were pending to start. I just need someone to re post the appinfo.xml for Seti@Home optimized and for the new 4.36 astropulse for a Linux X86_64 machine. It would be greatly appreciated. *************************************** -Steve |
