Even after the weekly outage ap_validate3 didn't come online again. What's going on with Astropulse? |

Would be nice if someone would say something, it has been off for weeks. Dave |

I imagine they want to clear the pipes first. One of the reasons i dont crunch APs atm. With each crime and every kindness we birth our future. |

IMO, it's analysis that's worthwhile to be done on the data in addition to S@h Enhanced. Whether they stockpile the results for awhile or not doesn't bother me. I do understand that credits are psychologically important to many participants, though. I just hope that anything which isn't working as smoothly as participants would prefer becomes a motivation to donate. If the total number of AP WUs which cannot be deleted because the validator isn't running gets large it may become a problem for the project, but they know what would be problematic and I don't have enough information to guess.

I don't think that it isn't coming online. Maybe that it is running in spurts. Out of my AP tasks that have validated 3 of there were today. 11 Oct 2011 | 20:39:52 UTC 11 Oct 2011 | 9:27:34 UTC 11 Oct 2011 | 3:05:04 UTC The most recent looks like it was after maintenance as well. Most of my 96 pending are waiting on wing men. :/ SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

That's why I am especially concerned (that my returned results may be for the dump). Petition against 1366x768 glare displays: http://www.facebook.com/home.php?sk=group_153240404724993 |

for science reasons it always makes sense to crunch AP's. For credit at the moment not ofcourse, but all we can do is sit it out... For the crunchers that only do it for the credit it's a painfull time, but remember : somewhere, somehow it will be fine again and all the credit will come your way ! Be patient, the guys in the lab are doing all they can with the resources they have ! |

Well, either they don't know that one validator isn't running and that the other ones can't keep up enough, or it's off on purpose (i.e. something broken with it, that hasn't been properly diagnosed/fixed yet). At some point it will get noticed/fixed. |

Well, either they don't know that one validator isn't running and that the other ones can't keep up enough, or it's off on purpose (i.e. something broken with it, that hasn't been properly diagnosed/fixed yet). Matt commented some time ago in Ricochet (Jun 02 2011) that: There are some broken astropulse results clogging one of the validators (which is why it shows up on red on the status page). We'll have to figure out an automated way to detect these results and push them through (it's a real pain to do by hand). I haven't seen either any report of an automated process for dealing with these, or any systematic search for the source of these "broken results" so that they could be prevented from entering the system. |

Apologies - but sometimes I don't understand the Seti gods! What I would do after a scheduled downtime: Check at least if everything on the Status Page is green. Why ap_validate3 is red now for at least 3 weeks is beyond my comprehension. |

Apologies - but sometimes I don't understand the Seti gods! On the SERVER-Status Page, there is a understandeble explanation of the SETI(@home) SERVER/Scheduler/Validator/UP-- & Down-Load, etc. of which you can make a "Block-Diagram" and (hope to) 'see through' it. When you've set your Preferences in your Account settings and have an AstroPulse app. installed for CPU or ATI / NVIDIA GPU, OpenCL app. rev.521, you could expect AstroPulse work. And AstroPulse work done in the near past, will help, if there is work, getting it! Also try to do some usefull Bêta-testing and app. tweaking, through command-line settings on revision 521 for OpenCL on ATI and NVIDIA GPUs.(WorkGroupSize=>256) And rev.365 for MB work, also OpenCL on ATI & NVIDIA GPUs.(WorkGroupSize=>256) {Have a look in the Bêta for WorkGroupSize 128, (ATI)-GPUs} |

Apologies - but sometimes I don't understand the Seti gods! Because ap_validate1 and ap_validate2 are working so they don't want ap_validate3 to run? Each ap_validate is identical and only one of them needs to run. They have more that one only to process results faster. |

Apologies - but sometimes I don't understand the Seti gods! Joe had mentioned before: ap_validate1 checks "astropulse" if any unexpectedly appear. ap_validate2 checks "astropulse_v5" if any unexpectedly appear. ap_validate3 checks "astropulse_v505". So ap_validate3 is highly important to the current work going out. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Apologies - but sometimes I don't understand the Seti gods! Yes, and Richard posted a bit ago what I mentioned in another thread.... I am not sure the validation stalling AP WU bug has been completely worked around yet. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

I seems to be working, I just had 811841716 WU validated by the THIRD person...it had been waiting validation after being validated twice for some time. Now it is offically validadated. SETI@home classic workunits 4,019 SETI@home classic CPU time 34,348 hours |

Hmmm, but on the oher side... http://setiathome.berkeley.edu/workunit.php?wuid=828992536 It's really seems like waiting for AP_validate_3 |

The oldest pending AP task I have with a 2nd result waiting to go through the validation process is from the 8th. Being a few days behind doesn't seem to be to bad to me. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

I have 3 Ap in pending from 8Sept, 18 Sept, and 28 Sept. Lucked out and have 6 running on the I7 and 1 on the Old P4. I like running AP, Wish I could get more. Theres been more than one occaision where running AP tasks has kept me crunching for Seti. [/quote] Old James |
