Hi John

If you fancy running a regional spinup model for the Beta2 project you'd be very welcome there:

http://cpdnbeta.oerc.ox.ac.uk/

The models are very long, 200 years, but they do run stably. Later, each completed spinup will be used to drive (= feed data into) hundreds or thousands of regional models. It's more important to keep models running than to complete them fast.

(I think Tolu will add credits earned on beta2 to our CPDN accounts but he hasn't enabled this yet - we're accumulating beta2 credits but they're not being exported for the time being.)

Best wishes

Mo


Anyone interested? I've formed the team there and downloaded a WU....

...and you were up very early!

Anyway, joined the team (thanks for setting it up) and downloaded a wu. I hope Mo's right about speed not being important, it's going to take me a very long time to complete. Realistically, they probably should be crunched by something more powerful than my aging AMD, but at least I'll keep you company over there until the cavalry arrives.Very Happy

Had a shufty around the message boards and seen some of the results coming in.

I saw a WU on one of Les Baylis' machines deliver its first trickle at 13 hours CPU time.
Be prepared for a long, hard crunch!

Ok, I've done the maths and I estimate that I should be able to complete it by Christmas. Mind you, it is sharing with the 15 other projects I'm currently crunching. Oh, that's Christmas 2017 by the way. Any sign of the cavalry yet?

At 200 years this one is definitely in the crunching for science category.
I've just started one model, early indications show a 108 day run.

CPU is a 6700 Core 2 Duo running at stock speed. Being one of the older B2 stepping revisions it's not very energy efficient, even with lapping plus Artic cooling it's running at 54 degrees. Global warming production and science in an Intel wrapper Laughing

Good to see you aboard, Sir!

This thread
http://cpdnbeta.oerc.ox.ac.uk/forum_thread.php?id=53
in the Beta forum is where a lot of the discussion for this type of WU seems to be taking place. (Seems that trickles are going back but not being shown yet)

One more team member to join us there and we have The Three Musketeers!

Does that mean I'm D'Artagnan? Slight problem though, this is Team England!

I'd also like to point out, at this point I'm joint leader with you two, YES!

I'm still running a spin-up model; expected to finish in 3 - 4 weeks.

Credits WILL eventually be granted we have been assured -
http://cpdnbeta.oerc.ox.ac.uk/forum_thread.php?id=36&nowrap=true#1325

As of today, 15th June, as I've just passed the 100 trickles point, that means 31,000 credits to come!

Please read other posts in the forum - the models are all crashing at the 80% mark BUT THAT IS OK.

Cool

Les Trois Mousquetaires were actually Porthos, Aramis and Athos. d'Artagnan was a wannabe mousquetaire. Given the power of you three, I think the analogy just about works. One for all, and all for one! Laughing Laughing Laughing Cool

The first spin-up WU completed sometime last night and I've started another one -
http://cpdnbeta.oerc.ox.ac.uk/results.php?hostid=287

Although the first one says 'compute error', that is fine; all of the models are crashing at year 2080. (see previous post in this thread)
