My PC worked on the project for 2 3/4 hours and I have only 0,070% done. So it would take 2023h to finish the job.
Other Projects take 5-7h to finish.

Is that time normal for climateprediction?

Yes.
3-4 months continuous on a fast computer.

I have just started with this project and my first download was a project of 3032 hours, which took all night to load and was some 400MB in size. Now I am finding that as I progress through this project the first 8 hours have been added on to the COMPLETION TIME meaning that even though I\'ve done 8 hours of 3032 I now have over 3040 hours to go. This project has a finishing date of 4 April 2008, which I wont be able to do the way things are going.

My other Boinc projects are usually only an hour or so in length, a lot more fun than this one.

Should I abort this and start again ????

The 3-4 months on a fast computer means no other work being done. The \"slowest\" computer CPDN runs on for me will take about a year to do, with 3 total projects on that system.

Do not worry about the due date. It is arbitrary. Crunch away, let it do it\'s job. The time will settle down after a while, and you will see what it really is going to do. More memory would help on your machine. Getting it to 512M would be a definate help.

On an older machine like yours, it may take quite a while to do, but all the units are the same size, currently. Until they start doing the broken down units, these will be the norm. They made the announcement about a month ago, but no timeline.

My best suggestion is you need to decide yourself. If you want your machine to crunch this project, let it roll. If you want to wait until they get different sized units, kill it and detach for now. The work will go to someone else if you abort it.

Thanks for that. I detached and got the error message

MESSAGE FROM SERVER: NOT ENOUGH DISK SPACE (ONLY 538MB FREE FOR BOINC)

Tis odd when I have 1GB allocated for BOINC usage.

There are no REAL deadlines for this project, but something had to be put in that field in the software.

BOINC is optimised for the short WU projects, and is VERY bad with this project. The only way to work out the time to complete is DIY; time the duration of one model year and multiply by 160.

It\'s recommended that you set the prefs option: Leave applications in memory while suspended? to yes, otherwise you can lose a LOT of processing time if the model doesn\'t run long enough to reach a checkpoint.
It\'s also recommended NOT to use the screensave for this project. It can use up to 50% of the processor time on slower computers, just to continuously calculate the graphics image.

To find out how long to the next checkpoint:
In Show graphics, press the Z key to remove the overlay, then press 8. This will show a countdown timer.
When it reaches zero, it will save the data. Wait long enough to be sure it has. (When it gets back to 400 and something.)

There\'s no point in aborting the model. You\'ll just get another one the same, time wise.
However, your computer is under the minimum recommended specs of at least 512 Megs of ram, (the model can use up to 380 Megs), and at least 1.6GHz (to complete in a reasonable time).

edit
OOPS. Beaten to it. :)
