It's fairly clear that the recent updates we made to the general mysql/state counts/splitter fold has vastly improved our recent weekend woes. There were still a couple dips here and there, but no wild swings like before. Except this morning one particular query - from the scheduler - was clogging the works. We figured we'll just let it push through, i.e. let nature take its course. We assumed it was an expensive lookup, but after a couple hours of waiting I ran the same query on the replica and found there was only one (!) row in question. So what the heck is mysql doing? We killed the query and eventually the logjam cleared. I'm finally scraping up enough space to pull a lot more work up from our archives, so Astropulse will be kicking in again, at least at some low level. This should also help reduce the deman on our limited resources since those workunits take longer to process, which means a lighter load on our database/download/upload/scheduling servers. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

I can certain say that the title holds true for right now. But, I'm running out of work again... check the queries if there's anything stuck again... Edit: Never mind, the work just took freakishly really long to get via scheduler requests... What if Fiction was Fact and Fact was Fiction and vice versa? |

... so Astropulse will be kicking in again, at least at some low level. ... Thanks for the info. Could you clarify, please, whether the data fetched back from storage (like 05mr09ad currently splitting) will be split and scheduled for the general _v5 (503) application we've been using for a while, or the new _v505 application installed for Windows only on 10 June? It would help the optimisers plan their testing and releases. |

Excellent news Matt. I know the community in general is probably glad to hear that AP work is coming, and Im sure your pipeline/databases are going to like you more as well. |

Not only this thread. :-( I have seen this error in the NC forum also. And I have noticed that some threads says that the last post was made a few hours ago but in the thread itself the last post was made yesterday or even months ago. See as exsample these threads: http://setiathome.berkeley.edu/forum_thread.php?id=54092 http://setiathome.berkeley.edu/forum_thread.php?id=53702 |

The server may be mostly up, but there's almost no I/O going on. See http://fragment1.berkeley.edu:80/newcricket/grapher.cgi?target=/router-interfaces/inr-250/gigabitethernet2_3&ranges=d%3Aw&view=Octets C Join Team MacNN |

Oh, and all my tasks are "downloading": seems like one big mess. |

Ditto in Chicago. Download is starting but receiving zero bytes for each file, in two different location on Mac and Win. Darek |

Anyone noticed that the works units they managed to send back today still appear as in progress? |

Dan Sosebee, From yours: Yep, same thing happens when I try it. Also having problems downloading work so I suspect it's a database error. I'm sure they'll fix it as soon as they can. I'm sure they will, I just wish they'd post some information about what is going on. Rad |

I just wish they'd post some information about what is going on. Do you want them to stop working on the problem(s) and post, or do you want them to put all of their efforts into fixing it and post later? |

BTW, whoever kicked the server this morning, thanks a lot :) I've never quite understood why people get so emotional (angry, seeing red) over anything at this project when 99% of the time things can be explained in a rational way when given a chance and a bit of patience. |
