News:

February 7, 2007
The project servers have been going up and down over the past 48 hours. Most of this is for diagnostic or rebuilding purposes, and we hope to be at least partially back on-line before the end of the day.

Technical News:

Eric, Jeff, and I were in the same room together for an extended period of time for the first time in weeks, so we had a code walkthrough this morning and database correction code. What does this mean? Basically, with all the different SETI@home clients over the years (classic, BOINC, enhanced, and all minor versions within), we have had various bugs (or features) which resulted in signals with varying minor issues in what is now our unified master science database. All the data are valid - I hope there will be more verbose text about this cleanup procedure at a later date. Anyway, this morning we walked through a program (mostly written by Jeff) to unify all the signals so future analysis will be much, much easier. Minor edits and major testing will have to happen before we run this on real data. I only mention this in case anybody was worried that all we do all day is put out server fires and nothing scientifically producive. We also had a science meeting where we discussed, among other things, our current multibeam data pipeline - we're have been successfully collecting data from the new receiver for months, and we're really close to sending this data out to our volunteers.

As for the project going up/down. Well, right after my last note I went to sleep with the servers happily recovering, but then we hit that same ol' database problem (slow feeder queries gumming up the works). We battled that all day, tweaking this parameter and that, dropping a deprecated index, restarting the database over and over and checking its I/O stats... Nothing really obvious came to light, but Bob configured the database to make it less like to try to flush modified pages in memory to disk, and that seems to be working for now. All the other problems mentioned yesterday are no longer problems.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind...

Thanks for the news, tech news & SETI@home daily stats Rattledagger :beer:

 

[Assimilator1]

our current multibeam data pipeline - we're have been successfully collecting data from the new receiver for months, and we're really close to sending this data out to our volunteers.

Cool! ,good to see they got the other problems sorted.
