Message 906296 - Posted: 11 Jun 2009, 21:52:12 UTC

Spent the morning clearing out my mail spool - something that could easily eat up a full day if I let it. It's amazing how these "this will only take 5 minutes, tops" tasks add up, especially when there are about 100 of them.

Bob found the mysql replica has been falling behind a bit more than he though it should, and after some poking around I found iptables getting in the way. So I did some reconfiguration on that system, rebooted it, and now let's see if it is operating any faster... This wasn't the crux of our mysql woes, but it may help a little bit (less chance the stats queries will rely on the master if the replica is always caught up). Actually as I write this I see we're in another difficult period. Eric was actually just up here and suggested a workaround for one of the queries that has been given us the most headaches lately. We might implement that in the near future. We also should try throwing some of this new hardware at the problem (if we could ever get it working).

The dust is settling after the anniversary a bit - still haven't gotten any video from the students putting it all together. Dan, having spent some time in Arecibo recently has new insight about the radar problems we've been having - so I may get yet another code rewrite on my plate in the near future. Hopefully this will be the final revision that will actually get completely and be used to clean up a huge backlog of dirty data (waiting to be processed). Jeff and I hope to also get some NTPCkr far enough along to present something to the public. I know I've been saying that a while.

I know it gets written here a lot, but... thanks for the update!

It gives an interesting view of "the behind the scenes" ;)

Indeed...daily news brief here for some of us.

Thanks very much. These updates are more important than many realize and very much appreciated.
Sounds like bluer skies ahead. Sorry about the Intels, talk about frustrating. Best of luck for bringing them online sooner rather than later.

Also, I know more to do is the last thing you guys need...but..
How about some new pictures around the lab, or of the Intel installs/setup..
No stress, just wanted to make the request. Would love if there were a photo to go with the updates! =P

I will add to the comments already added here as well.

The updates, while these (and I say this not meaning to offend the user group), probably don't mean too much to people (Q opening floodgate of comments on that), they are very much appreciated by those that do understand them.

It still amazes me how you guys all pull together to keep "the mother of all BOINC projects" up and running to keep JOE PUBLIC happy, given the limited resources you have at the lab.

Patience is a virtue as someone said :-) and given time, the new generously donated servers will kick into gear and I am sure help out a ton.

While we are all looking forward to seeing NTPCKr "go live" , what effect does it have on us, if you guys take whatever time you need to get it working how you want and not rush it live? - NOTHING, it is you guys that run this to keep us happy, personally I couldn't care when it gets released (yes I am looking forward to the day it does) but at the end of the day, I have no control whatsoever as to when it does go "live" and will not push for it to be ready until you guys are happy with it.

Yes it can also be frustrating when things do go "up Sugar, Honey, Ice, Tea" Creek, without a paddle" but then again, we as users deal with it.

Anyhow enough rambling and ultimately thanks for the update and as Westsail & *Pyxey* said, Blue skies are indeed ahead.

Yes Matt, your efforts are appreciated....
No matter how mundane the tasks are to you, the myriad of things you deal with on a daily basis are interesting to many of us.

Yes, it is amazing how the 'little tasks' come along one after the other, and soon eat up a whole day.

Thank you for the time you put into posting these notes.

huge backlog of dirty data (waiting to be processed)

Thanks for the updates I'm very interested in what goes on behind the scenes as we all are. When you say a huge backlog are we talking months or years and will this data average 15 hours per work unit os is this to hard to tell? Thank you in advance.

Forced by the boss (Dave A)would be more like it...LOL

*********
One day in the space sciences labs at Berkeley..... A long long time ago.


    :Dave A says - "Dam volunteers keep asking for news about what we are doing here in the labs. There's no way i can tell them we twiddle our thumbs all the time! I'm definatly not telling them about the recent signal we recieved from Alpha Centauri"

    :Matt L says - "Yea Man! If they found out we would be up sh** creek!"

    :Dave A says - "Matt, will you start writing some rubbish in the message boards to keep them occupied?"

    :Matt L says - "No way Dave, not my style Man. But i will write some tunes about this and the band will play them on Friday nights!"

    :Dave A says - "Matt start blogging about how bad it is here and make up a bunch of lies about the servers or your fired buddy!!!"

    :Matt L says - "Way layed dude!!.... Sure thing!"

    :Eric K says - "You should write the music anyway Matt!, i like songs about server troubles and Aliens"

That is the cunning plan. In fact the whole team really IS from Alpha Centauri and just don't want to let us all know.

My last result report was at 16 Jun 2009 10:13 UTC.

At 16 Jun 2009 13:08 UTC I took the PC offline because no new work. [~ 3 idle hours]

The PC had a 5 day cache and ran out of work..

(4 x GTX260 Core216 -> ~ 800 MB WUs / day)

When I can switch on the PC again, when is new MB work available?

Hopefully Matt is not sick again like last month.

If on vacation, we hope you enjoyed it.

It has been stated many times there would be times where no work was available. I would presume that you need to be patient just as everyone has to be. If you put the PC back online, Boinc will check everyso often and when there is work, there is work and will get it automatically.

..at full load the PC take ~ 700 W.. ;-)


How could BOINC request new work in standby status? ;-)
