From mo.v on the regular CPDN boards (News), 16 November 2006:
We\'ve now passed the initial target of 2500 transient coupled (160-year) models

http://www.climateprediction.net/index.php

but Carl\'s now saying that the Oxford researchers do really need 5000. So please keep going!


I\'d be happy to finish off the last 45 years of this model if you can find a way to send it back. (It apparently tried to write to the disk at the same time the virus scanner was looking at that block. Unfortunately, no back-ups on my end -- a lesson now learned and applied, thanks to the helpful posts by Les Bayliss and others.)

The model was running pretty hot in surface and ocean temp, but in the middle of the pack for precipitation. I realize it is probably an incredible pain to locate one model and its various pieces, so I truly don\'t expect it, but if you get bored one day...--) In the meantime, happily crunching away on the next model, and have boosted the CPDN resource share now that SAP has finished.

There is only one place that a complete model exists, and that\'s on the computer of the person crunching it.

A small amount of data is uploaded every 10 model years, with a bigger restart dump every 40 years.
And someday, when the software has been written and tested, it will be possible to use these restart dumps as a starting point, no doubt allocated randomly to people, just as are the present datasets.

Until then, commiserations on the loss.

Thanks for the increase in processing time.
I haven\'t quite finished my last SAP, as I\'m using it to sync my cpids on 3 projects just for the heck of it.
But I\'ve just returned my first trickle here since my sulphur finished in April.
These TCMs are going to be a long, hard slog, compared with SAP.

I don\'t think you need to actually be running a model to sync, just keep updating all projects on all 3 PCs and it\'ll eventually go across

I also increased my resource share from half to two thirds... figured you needed the crunching time most atm. Unfortunately, I\'m only 11 years into the model, so, even with a higher resource share it will take a while longer.
