Technical News, and SETI@home daily stats for 11.01.2008.

Triple Shot Cappuccino Day (Jan 10 2008)

The public web site servers slowed to a crawl again this morning thanks to several robots/spiders scanning us at once. So I took another gander at my robots.txt file and used Google's webmaster tools to check how well this was being parsed. This uncovered a typo (a missing "s") and while I was at it I added some new rules to robots.txt. We'll see how this all fares.

Bob and I brought the BOINC/science database servers down briefly this morning to tweak some parameters and clean out logs - some of you may have noticed a brief data server/web site outage in the process. The only tweak of note was on the science database: we reduced the checkpoint intervals and increased the between-database-ping timeouts. Why? We've been seeing the secondary spuriously enter recovery mode due to being unable to reach the primary, when really the primary was simply busy doing checkpoints at the time. Anyway, outage recovery was slowed by confluence of various stats/update scripts starting up while the database was busy flooding its memory buffers. We really need to optimize those stats queries someday. As well a relatively new BOINC feature ("resend lost workunits") was eating up a lot of database too, so we turned that off for now. Actually that last thing helped immensely.

In the process of general disk cleanup, etc. I'm now forced to finally populate the credited_job table with three years' worth of purge archives. These archives are taking up 200GB on a 1TB filesystem which we really need to convert into workunit storage sooner than later, hence the push. Reminder: this is the table that contains the history of which users processed which workunits.

Just between you and me... In addition to the outbound traffic squeezing through our maxed-out router, I am now sneaking our an additional 5-10% over the campus net. This is thanks to the simple/useful "pound" load balancing utility. The campus net can definitely handle this tiny increase. In fact I might bump up the percentage. But don't tell anybody. Mwha ha ha. [edit: I brought that percentage back down to 0% an hour later - we'll keep this extra power in our back pocket for now.]

By the way, the optimized client discussion has been taken offline and is progressing. Turns out this may actually be a single bad host more than a bad client.

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...

lol nicking uni bandwidth!:Q:laugh:

Low output ,what happened?

 

[petrusbroder]

Thanks for the info and the stats, Rattledagger.

I hope the output will proportionally larger tomorrow - at least I had some 30 WUs not reported this morning ... :Q and I flushed them to the project.

 

[dajeepster]

I haven't been in town for a week and M$ did an update last week so I lost most of my computers outputs until I get back from vacation. that's about 15k worth of outputs... so we'll be down that much until I get back into town.... mid next week.

 

[Assimilator1]

Damn MS ,I assume you don't have auto-install on? ,not that I blame you

Awesome output you have ntw!:Q
