The last 2 days I have been able to recieve work but completed tasks wont clear up. I keep getting the message that internet access is ok but servers might be temporarily down. If sight was down i believe i would not recieve any new work. Anyone have any insight, have about 10 tasks per computer waiting to upload + 5 computers. Need answers Thank you

Look for explanation in the Number Crunching forum, latest posts in the Panic tread. The servers are overloaded.

... a temporary stop to AP downloads, until the cause of the anomaly can be investigated and corrected. Once the runaway download train is brought under control, uploads will look after themselves.

After having a few more looks at Scarecrow's AP graphs thoughout the day, this measure gets my vote. It's all those AP units being downloaded that's clogging up the pipe.

OK, had a night's sleep and I think I've found the problem - well, the next stage in the chain.

Have a look at WU 417685549. Downloaded seven times, mine is the only one which is running - every other copy failed because they couldn't download the executable file. All my recent AP allocations look like that, though this is the most extreme.

Eric needs to turn on the 'proxy server' distribution channel used when new MB executables threaten to clog the pipes - or AP distribution needs to be restricted to those who have manually downloaded and installed the new Lunatics r112 optimisation for Astropulse_v5 (plug!).


As far as I can tell, they have Coral Cache turned on for the AP v5 as this link still works. The problem is a lot of the antivirus apps mark the redirect as suspect and do not allow the download to happen.

Of course then then we get the task errors because there is no app to process the work.

I'm still getting problems on uploads, Someone suggested in the last thread(#12) that donating $5 or so(whatever one can afford right now) from everyone here could go towards fixing the bandwidth bottleneck We have here. As in 3 Days and 3:55(Hours:Minutes) I will be running on either fumes or be empty here, I can take $10 from My savings account on the 27th and earmark It for Fixing the Seti Bandwidth Problems.

That's also true, but I'de rather be able to UP- & DOWN-load, since >200 WU's are trying to get 'IN' and some new WU's, would be nice, too.
This is too much (excitement), for me ;^)

Does this happen EVERY weekend or what?? Cant upload cant download what a farce! I thought this was an established project? Most Alpha & beta projects are able to run without a weekly maintenance shutdown & a weekend server outage every weekend. So what gives??

Seti@home is one of the oldest projects out there, and has a large user base.
Large number of users = high trafic and at the moment, the pipeline just does not have enough bandwidth.

If I am understanding the problem, increasing the bandwidth won't do much.

The amount of data each user is asking for per day is a few GB due to the looping effect ... we are talking several tens of thousands of users here.

Yes, almost every weekend, starting last christmas and even before that :)

I thought this was an established project?


No, this is just a test lab :)

(Sorry, I couldn't resist).

BUT, I won't give up. I now have a lot op AP's to upload which will be credited at once, once the upload problem is gone, because there're all re-issued ones :) Still waiting for a 5.03 WU though.

Of course, if you think that through, maxing out your cache settings is inherently self defeating in the long run. ;-)

What if everybody did that? :-)

In any event, this is the weekend so I call it 'Par for the course'. If it was Wednesday OTOH, I might think about having a minor Panic. :-D

Have not been able to upload for about 16 hours now, more than 500 WU to upload. 4 day cache, so i guess it is not an issue at the moment.

BUT:

Looking at the server status page and Scarecrow graphs makes me wonder.

Normally MB WUs return at the rate of 10 to 20 to 1 AP WU.

Why is it suddenly appear easier to return an AP work unit than an MB WU ??

Presently the ratio is 2 to 1, prox.

What sort of timescale are we looking at to clear the backlog.
I only keep about half a days work,so I ran out of work Sat lunch time.
I have 50 or so wu's to upload.
If there are 50,000 hosts each with 50 wu's ( average say ) to upload that is 2.5 million wu's.
It is like a lake full of water trying to go down a 1 inch pipe.
It could take days to clear or am I on the wrong path.
