Message 918280 - Posted: 15 Jul 2009, 23:41:29 UTC - in response to Message 918267.  

Everyones else machines are trying to contact the Servers and that is what Boinc was designed to do. If you let it do it in its own way things should be fine.

Ok
I will let my computer to manage itself.
But isn't it a problem if it contact server all the time for upload?
Not for me, it's just generate lots of error message pages. but for SETI server?

Regards.



Perhaps they could make a changed to the client app. When it gets one of the "Internet access OK - project servers may be temporarily down." then it could back off all the uploads instead of just the single one. Seems like that would DDOS the servers a bit less.

Actually those changes are being discussed at the Developer Level. Cuda being the animal it is and the outage here has proven that changes need to happen.

That's good to know. If there is a beta app with any of these new "improvements" out soon I could toss it on a box or two in my test lab at work if more guinea pigs are needed.

I made a small change that tripled our upload bandwidth. The change is to quickly drop excess connections rather than let them wait in the TCP queue.



We were doing this last week, but apparently Matt turned it off. IDK why. Matt is on vaca now.

I am happy now. My main machine just reported about 400 or so WU's.....only about another 400 or so to go by the look of things, then I can start downloading new work again.

I am on the road to recovery.....well, this system anyways.

I've not bothered to count all the wu's I have for uploading, but my total is down to about 230mb of space seti@home is using across my machines. I don't want to think about what all my machines at work have stored on them lol.

I would presume that someone sent a email that caughts Eric's attention.

It looks like the major portion of the rush has been dampened a bit.

Clearly it helps. Thanks for linking to Cricket so we can watch how it changes.

I was just looking through the message log and got excited....lol

On this machine, on a 22" monitor @ 1680x1050 res, I have noticed that I am averaging 1 FINISHED result per complete vertical feed of text on the screen.....lol.

It's gonna be a while, but atleast it's finally moving.

The interesting part is when it gets below critical mass and the requests work. Over the years have also found it interesting is how Boinc is better at "guessing" when to retry and be successful.

Well I see there are a lot of uploads going through (cricket, and server status page shows a large number of "received in last hour"), so I know uploads are going through. Every time I try, I get an instant "http error" and the exponential backoff occurs. I'll just leave networking suspended for more time.

Ah, that would explain why some of my uploads are going through, and others are timing out after a second or less.
