Message 30723 - Posted: 26 Sep 2007, 23:42:48 UTC

Hi,

I\'ve been running a climateprdiction app in my Bionic client for a while now and it\'s at 22% still with 1400hr s to go. I\'ll be going overseas for 6 months soon and as i understand it this means that the job number will probably be given to someone else due to my inactivity.

What i\'m wondering is whether its possible to pass on the data i\'ve processed to someone else so they can continue it? Its seems a waste to hahve processed all these hours (511) to just have it someone else start from scratch.

thanks

orfeo

If you have a friend prepared to download boinc and complete your model, yes it can be done and we can explain how.

CPDN doesn\'t organise this sort of thing though.

If you haven\'t got a friend able to do this, I suggest the following. Look at who is sharing this workunit with you:

http://climateapps2.oucs.ox.ac.uk/cpdnboinc/workunit.php?wuid=6078981

It was sent to 8 computers and you\'re #8 in the list, processing successfully. Computers #1, #2, #4 and #6 have crashed the model (I didn\'t check whether any of them have later restored it from a backup to continue processing it). #3 and #7 haven\'t started it. Computer #5 has reached 2028. This is a typical situation for a workunit - most members with processing problems don\'t come to the forum to get help, so a lot of models crash.

When you return from your trip you could look at this workunit page again to see whether any of the other computers have completed the model (we can help you check this, in this same forum thread). If another computer has completed it, abort it then. If nobody has succeeded, continue the model.

I hope you\'re going somewhere nice for six months.

IF you wait until the model reaches just over 25% (1960) before aborting it, the model will send a \'restart dump\' to the servers. This can theoretically be used to continue onwards from that point.

cool, thanks guys, i should reach 25% so maybe i\'d consider dumping it, but i worry that may actually mean that the work gets lost and wasted so maybe i\'ll just hang onto it for the 6 months and see how other people go. Unfortunatly i haven\'t been able to convince my friends to get on bionic :(

Every complete 10-year period, which results in a zip file being sent to the server, is used for the research, so what you\'ve done will definitely not be wasted.

It\'s not easy to convince everybody that boinc projects are a good idea, is it? I feel the same way about bungee-jumping.

Hang on a sec - this is an 80-year 2000-2080 model which has reached about 2018 or 2019. So it won\'t reach the 40-year restart dump until 2040 which is over 20 model years away.

Before you go away the best thing would be to get it past Dec 2020 or Dec 2030 depending on how much time you have left.

\'Doh!\'

I keep forgetting that there are other options apart from 160-year coupled models now...

That particular model may get lost, but so do thousands of others for various reasons. And there are millions of combinations for the researchers to try, most of which never will be.

As for wasted, data is returned near the end of each model year, and if you can get just past a 10 year period, a larger amount of data will also be uploaded as a zip file.

So there will be little \'waste\' from you stopping before the end.

yeah when i get into my uni break i\'m going to email the deal to see if i can convince him to put it on the library computers, 100\'s of computer just sitting there while people look at email and the library catalogue
