We quickly wrapped up another database compression/backup this morning. It only took two hours as the database is now at its minimum size given our current operational status. Some extra time was spent rebooting the database server to change a BIOS setting (that was causing harmless but annoying messages to clog the server logs).

We started early as we were hoping there were batteries arriving to replace dead ones in one of our UPS'es, but they didn't show up this morning. Had they been here we would have shuffled some UPS'es around during this outage. Maybe next time. At any rate, since we are nice and trim and all caught up we shall go back to weekly Wednesday outages for database compression/backup.

It should be noted we are currently processing 1.2 million results a day, which is far above our original hopes of being able to process 1 million results a day. But apparently our servers are pushing their limits, and certain events can trigger a month-long back-end malaise. Future SETI@home applications will have workunits that take longer to process, which will help. We also hope to acquire newer replacement hardware as well at some point. Like a database replica server so we wouldn't need these weekly outages.

The main part of the master database merge is done. We are now planning the shape and scope of the outage for the final part of the merge. Unlike what was stated in the previous tech news item, it may take longer than a day to do this - we want to make this a "partial" outage (during which users can still upload/download work) so it will take some careful planning to minimize any "full" outage time.

In other fun news: We finally got around to adjusting Classic credit for users that showed obvious signs of cheating. In Classic, it was very easy to cheat the system to get credit without doing any actual work. We ended up partially or entirely removing credit for about 900 of the top 10000 users (all of which had about 20000 or more credits). Below that there wasn't enough data to show obvious signs of rampant cheating (not to mention enough time and disk space to run the checks on the remaining several million users). These adjusted credits should be sync'ed up with the BOINC databases soon if not already. Case closed.

This among other things means TeAm Enterprise jumped to #62. :cool:

It appears we stayed in 5th place. I'm really glad in a way that the purge didn't lift us higher for the implications for the teams above us would have been disastrous.

I'll do a comparison when I get the time and publish the names of the accounts that have now disappeared. I know that will be interesting reading. ;)

edit: Though I am very happy to see we actually finished 4th, I feel very sorry for all of the "good" people on S@N.

The team-stats isn't updated yet, so it looks like atleast SETI@Netherland has "lost" their #1-producer...

Indeed, kind of like a "sexual preditor" list. Now, if we could just figure out who they are and where they live so we can completely embarrass them! :p

WOW...Great job SETI!!!

Dave and I moved from 472 to 305 - So, I could have stopped a long time ago and still been in the top 500 overall. :)

This job was done manually using Excel. If there are errors, they were inadvertent and I apologize in advance. It was very time consuming and for now I have stopped at just a few places below the top 100 for reasons that will be obvious. ;)

The name in bold had their totals reduced. There must have been something wrong with some of their WUs for this reduction. There should be no assumption that the accounts in bold did anything unethical. Their WU reductions could have been due to machine malfunctions and may even have been reported by the individuals themselves.

A forum-post...
315 of the top 1000 were obvious cheaters. Including the top two, I think. Well, they're not the top two anymore...

- Matt Lebofsky

Well, it looks like it wasn't top-2 but instead #1 and #3 was purged, still 31.5% of top-1000 being "adjusted" shows there's been many cheaters.

How this will influence team-stats is another matter...

After a quick calculation of what SETI@Netherlands has lost from the Top 1000 they are ahead of us by around 8000wu's. And that is just based off the Top 1000. We lost 0 wu's while they lost 5081168wu's

It will be really interesting to see the final lists when they are posted.
