I am downloading work, of course it is all for the CPU!!


Figured out the CPU only problem, I had a 5 hour backoff on SETI Nvidia work requests.

Zeroed that out and back to requesting work for the 2 GPU's.

The question of the day: giving that SAH-assimilators were disabled probably till Monday, is there enough disk space for generating new WUs without deleting old WUs at whole week-end?

No, we will go belly up again at 12:25 CET Sunday.

That's like 24-hour time so... to me that would be after Sol is high in your sky?

Edit - better give me that in UTC.

CET is Central European Time. UTC+1. So 11:25 UTC is the prediction.

Requests for work result in "Project has no tasks avalable" messages, network traffic has just dropped off.
Ready to send is 0, result creation rate is 0. And there's a lot of red & orange on the Server Status page.


See the new post in News. Work production is turned off due to a problem with the new table.

(Hilarity ensues, courtesy of Sten-Arne.)



Well, humour isn't appreciated in the News section obviously. The entire thread got hidden. I have to work on being more serious, and never again crack another joke, or being light hearted.

Anyones guess..

OTOH I see E@H had a similar problem and cured it be only giving out WU with a expiry duration of 7 days.. According to them this enables them to have a much smaller databse table.. Guess it must be about coffee table sized instead of s@H's banqueting table sized one:-)

The humor was very much appreciated! I took the thread down because the problem was resolved. I just un-hid it.

Any news about seti@home using part of the berkeley lab bandwitch?

With so much fast WU (2min on GPU) we still going to have problems, even with the new donated servers.

Shorter expiration durations has been discussed over the years, and I think it makes sense. It reduces the storage requirements and general hassle, and doesn't impact the bandwidth (in the steady state). One counter argument was that some folks only hook up once per week. Really? Is that still a valid counter? Look at the reduced performance the rest of us are getting, in part as a result. I think centralcommand should try to trim the expiration date as an experiment and measure the benefits. If we lose the once-per-weekers, perhaps they will find one of the other boinc projects as more suitable;(of course I hope there are only a hundred or so such folks.)

Look folks.........

They have enough problems right now keeping the able bodied kitties supplied with work.

Concur completely, Mark. The thought that willing participants should be forced away solely because their computers are not "recent/state-of-the-art" is abhorant to me, and contrary to the basic premise of the BOINC infrastructure.

Old and slow, but still good enough for what I use it for ... including Seti@Home!

As one who has been in the situation of only being able to connect at random intervals I can honestly say that the short lives offered by some projects are a deterrent to participation.

I think NASA would have a tough time keeping you supplied with work! ;)

The issue of cutting off the old and slow by lowering the expiration times is the same argument for cutting off old BOINC clients. "Anyone using a really old version makes me loose 0.00015% of the credit I would otherwise get! So we should set a minimum version." They return good science results so there is no reason they shouldn't keep processing work. Same with the slower processors.

If the longest anyone is taking now is < 5 weeks I wouldn't see an issue from changing the default 6 weeks down to 5. However I bet there are a few machines out there taking 5 weeks and 6.75 days to get though some work.

I dont see that trimming the expiry date would disenfranchise users, even those with 'very' old rigs..

It 'might' mean that 'some' users would have to accept smaller amounts of WU at a time to process, just sufficient to process in the time available.

It might make everyones d/loads easier in fact if smaller amounts were being taken at any one time by people.

Those old and slow machines would still be able to contribute to the job in hand, just that they would'nt be able to hold tons of WU in reserve.

If the present expiry is 6 weeks or more then decreasing to 5 weeks should'nt cause a major problem.

Particularly if it were to be implemented for a trial period to see just what the possible benefits and drawbacks are.

My tuppence worth, since I seem to have started this furball off:-)

Yep it's down but that's because there is over a quarter million ready to send (that will pick up if it drops below that number) and I'm only picking up a few at a time since yesterday as I'm still bouncing off the limits. :)

Cheers.
