Every time I start up my PC and Boinc loads the climatepredicto.net work block goes to 0% so I never can report it. I\'m on the latest BOINC client so whats am I doing wrong.

Hi Philip,

Your computers are hidden and you haven't sent any trickles in yet, so I can't track what has happened with the work units that have been sent to you.

Having said that (and assuming you're running some version of Windows), my best guess is that you're being hit with a problem in the shutdown sequence which can cause corruption of a file that controls how the model starts up. The best way to get round this is to manually exit from BOINC before shutting down. If you're particularly paranoid you could always do a suspend before closing BOINC ;-)

CPDN checkpoints the result (writes it to disk) once every 144 timesteps. If you stop the computer before it reaches this point, it will restart at 0. If you have a very slow computer, and are sharing the CPU with another project make certain that you have the preempt option set so that preempting does not quit.

The slowest computer that I have actually received a CPDN WU to crunch would take several hours to do 144 timesteps. The minimum recomended speed is 800. Much slower than than and you will take more than a year to finish on a dedicated machine.

The above may describe your trouble, more information about your computers would be very useful if I have not described your problem.

I don't think that it would work. I just suspended BOINC while installing a big program and when I continued it it was reset back to 0
Oh and I just checked and I'm on timestep 844
