Over the past few days (starting around Friday) we had continuing fallout with the science database repairs made over the previous weeks. Nothing we couldn't diagnose quickly or handle, but there were patches of low workunit availability. Long story short, after rebuilding our workunit table we hit some index corruption issues that didn't rear their head until we suddenly stumbled upon them. Today we dropped all the indexes and rebuilt them from scratch during the usual weekly outage. So far so good. I also used the outage this week to upgrade the OS on the scheduling server (which was fairly out of date). We also brought in some freshly compiled splitters which contain new database plumbing - a step toward us having the splitters themselves being more sensitive to telescope status when the data were recorded. This code is currently dormant but after some testing and calibration will ultimately keep us from creating and sending out large numbers of "noisy" workunits. This plumbing however hasn't been compiled yet into the Astropulse splitters, which is why they shall remain off for now. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Thank you for the update Matt. I can hardly wait for the new servers to arrive, and be of some help. I remember well the anticipation of when oscar and carolyn arrived. Steve Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website |

Yes, thank you Matt so much for the info once again, it is always of much interest to us what goes on each week. Helps some with a little less patience understand the things you have to deal with just to keep the project running. And the kitties are rather excited about the pending arrival of the new servers as well!!! "Time is simply the mechanism that keeps everything from happening all at once." |

This code is currently dormant but after some testing and calibration will ultimately keep us from creating and sending out large numbers of "noisy" workunits. Steady, Sten-Arne. AP will be back eventually, and it will be better than ever. You WILL survive. Just go ahead and allow MB now and it will stretch out your APs a bit. It's not the end of the world...

Ah yes - I just set the "show_results" flag back to 1. And just talked to the GPU gang - servers are done being assembled and shall ship later today or tomorrow. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Ah yes - I just set the "show_results" flag back to 1. Thank you very much, Matt!!! For both the return of the tasks page, and the great news regarding the new servers!! Meow! "Time is simply the mechanism that keeps everything from happening all at once." |

it really is amazing to know how much you use a feature and take it for granted, when it's down all of a sudden, thank god to have the tasks pages back i missed them. |

Ah yes - I just set the "show_results" flag back to 1. Thanks for that. It helped me to abort this unnecessary AP WU, which was already validated. Makes 26-28 hours of CPU time, which can now be used for something more useful. |

Hi Matt, Great news, I hope however this doesnt mean you have to work 24/7 to get them in and working.. Seems to me you've been pretty busy as it is. Dont want you going down with exhaustion.. The resultant outage would probably take ages to sort out. Regards, Cliff, Been there, Done that, Still no damm T shirt! |

Ah yes - I just set the "show_results" flag back to 1. New servers? I didn't find any news about new servers in Tech News! Yes months ago! :S The GPU gang has donate the latest server with many HDD's, but that was already a time ago! Were you talk about, is that the same one or a brand new one again? Is new, like to see specs! :) I do what I can and I can what I do! :P |
