Hi,

I keep getting "Weather at Home 2" tasks sent to my Boinc which are days long in length for processing. Last one was 3 days, current one is 11 days. These will take an incredibly long time on my PC to get through because I'm also subscribed to multiple other projects, plus it gets depressing seeing climateprediction tasks in my list that have hardly shifted in months.

There's no way to say "Only give me tasks that are less than 24 hours in length" is there?

Should I just untick the Weather At Home 2 project?

Sorry, but all climate models are big, and getting bigger, as the researchers move to more elaborate models. The w@h2 models are also their current favourite, as they can be run for different resolutions, and different number of model months/years.

But, yes, it is possible to choose which types you ask for.
It's in your preference settings on your account page.

And 3 days to a week is normal for most of the models, on most computers.
There are NO models that run for a day or less. Although that is a possibility with the w@h2 model types.

Another problem long running tasks face, is that the researchers can just give up, and issue a new batch, in the hope that they'll be run more quickly. Then they just ignore those results that come in months later.

Thanks for response.

Hmmm, I have suspended climateprediction project for time being in Boinc :( I'd love to contribute but I don't have the capacity really to do the long tasks justice.

I think the problem is that unless someone planning to sign up for CPDN gets round to reading the System Requirements page first they won't know that the vast majority of tasks take from a few days upwards to complete.

No need to be sorry, I didn't either and I haven't for World Community Grid either. What I should have suggested is that this is put on the sign up page for when you create an account.

Long? The ones that we have now aren’t long. You should have been running CPDN back in the days of the 160 year models. They took about 33,000 hours to complete on a single core 1.2 Ghz machines with 265 MB’s (that's right 1/4 of a GB) of RAM. That was about 6 months running 24/7. :)

LOL. Might have to give this project a break until I finish creating my supercomputer ;)

And, just to prove me wrong, a small batch showed up half a day ago that have only taken 9.5 hours to run.
