Typical Tuesday. The weekly outage went along just fine. This is the first time in many weeks the result table has been "lean" - i.e. no large excess of result entries due to blocked queues, waiting for purging, etc. How nice. Despite the happy current performance of our servers, we're still keen on improving science database throughput. We met today to discuss a plan to shuffle disks/RAID/LVMs around to optimize performance on thumper. I'm building the first RAID1 pair - it's syncing up now - where we'll start recreating indexes as soon as tomorrow. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Good to see everything went well with the outage. Seems all the hardwork you guys are putting in is paying off. Hope you are feeling better Matt and thanks for keeping us informed. |

We've found a lot of bad headers in the 13fe08ac data set. The client terminates with: SETI@home error -6 Bad workunit header !swi.data_type || !found || !swi.nsamples File: seti_header.cpp Line: 235 Here's an example WU: http://setiathome.berkeley.edu/workunit.php?wuid=234076644 There's a whole discussion about it: http://setiathome.berkeley.edu/forum_thread.php?id=45791 Any idea why this happened? Or can it be fixed so no other WU have this problem in the future? |

We've found a lot of bad headers in the 13fe08ac data set. Matt acknowledged the problem in the day before yesterday's technical news: the new splitter was generating annoying broken workunits that errored out immediately. Sorry about that. |

@ Matt - Eric mentioned re: the scripts on the Donation Pages are in need of a fix - i know that Berkeley got my Donation - my concern is strictly a reference to New Cruncher's that will Donate . . . (NO rush on my part - just to be clear Sir ;) BOINC Wiki . . . Science Status Page . . . |

I also reported this as my most recent donation does not show up. Would be more bothered if I had donated for a first time and there was no record of it, like you say. |

Matt acknowledged the problem in the day before yesterday's technical news: I'm a little slow, since I just got one of those broken header WU yesterday. Thanks for the update. |
