Hi

The one and only wu that I\'ve downloaded for climateprediction.net has always shown 2500+ hours to completetion. It does seem to be making progress (3.91% to date) but the Report Deadline has long past. Is this normal?

I\'m running the BOINC version (hadsm3 4.03) and my computer is an AMD Duron 1440 with 500MB RAM.

Check the year on that deadline date - I think you'll find it is 2005...

Yeah, that's very likely the correct runtime.

See: <a href="http://www.climateprediction.net/info/part_faq.php#q2.2">http://www.climateprediction.net/info/part_faq.php#q2.2</a>

and

<a href="http://www.climateprediction.net/info/tech_faq.php">http://www.climateprediction.net/info/tech_faq.php</a>

There are three phases each having 259248 timesteps, for a total of 777744 timesteps. How long each Ts takes depends on your CPU, OS, system load, etc.

My Athlon 1100MHz machine is running just under 8 seconds per Ts, that would mean over 1700 hours if running 24/7 with 100% Boinc resource share. And it will take longer now that I'm sharing some resources with LHC Project.

BTW: CPDN will generate a "trickle" message every 10802 timesteps, so you will see credit accumulating.

See <a href="http://www.climateprediction.net/board/viewtopic.php?t=2389">here</a> for advice on running it. In particular, it would be best not to use the screensaver and to view the graphics only occasionally, as they probably use a lot of your CPU. Disk performance can also play a part - it may be worth doing a disk cleanup/defrag (suspend and close BOINC first for safety).

Also wise to make the occasional backup of your BOINC folder if you have space.

Thanks very much for your response. The links to the faq were exactly what I needed to see. And, honestly, I did try searching for the answer before I posted my question.

Thanks
John

Yep, you're right, it says 2005. It never occurred to me that they'd allow that much time! I'm learning more about this all the time.

Thanks

I've never been one to want to waste cycles on a screensaver or viewing graphics anyway. But I will make a point of backing it up now and then...considering it's going to be working on this wu for MONTHS!

Thanks
