I just started this project not too long ago and I noticed that the Earth is black in the graphics screen.

Another thing, I have checked it in the past and the time frame for the model was the year 1810 and the end date was 2050. At 67% done, the current date it was working on was 1833. It would be impossible for it to reach 2050 at the current rate of completion. What is worse is that when I restarted my machine, it now says that it is working on the year 2052. That is beyond the end year.

I hate to say it but when I see numbers like this, I hope this is a typo otherwise there is no credibility to this project. By looking at the forums, there appears to be many serious bugs with this software.

I hope I am not wasting my time, electricity, and CPU time from other projects if this climate model is going to jump around like it doesnn\'t know where it started, where it left off, and what year it is suppose to be done.

Any help would be appreciated to convince me to stay with this project.

Hi Ivanhoe,

Could I point you towards the two \'model types\' posts (the first two in the \'information\' section) of the \'running the model\' readme? The link to the readme is in my signature.

These describe the time periods of each model. The model is looking at three different periods of 15 years, not a single block of years.


I'm a volunteer and my views are my own.

This is the 3rd time this week that this question has been asked.

And, as well as the posts mentioned by Mike, you should have a look at the Climate Science section, linked in the blue menu to the left. Especially the Experiment Strategy sections, which explain it all in detail.

And most of \"the bugs\" you\'ve read about are with people\'s computers. This is a supercomputer program, created by the Uk\'s Met Office, and it needs some TLC on some desktop computers to work happily.
But there was a typo in the label on the graphics display; the final year should have been 2065. This has been corrected in the new models currently being tested.

Hi
some pics of the graphic changes you may see as the model goes through the phases (33.333% and 66.666 %) Here .Easily corrected by suspending/the model/s exiting Boinc Then restart.

In the link you provided, my computer does the second one. (World turns into a black ball) I figured that was a glitch in the graphics portion of the system rather than the actual data being worked on.

I found the description of the climate model in the README that you provided.
The line in the readme for the UK Met Office HADSM3 that answers it is:

\"Each model has three phases, the first (calibration) runs from 1810-1825, the second 1825-1840 (a pre-industrialised level of CO2), and the final phase (forecast) runs from 2050-2065 (a post-industrialisation climate with double the CO2 level).\"

Hi, Ivanhoe.

I don’t think that you have a real problem. The reason that the Earth is black in your graphic is proudly that you pressed key “7”. This brings up brings up a black graphic that shows only the consentient outlines. Pressing another key such as “T” or “C” should bring up the temp. or clouds graphic.

As for your second problem, it isn’t a problem. You are running a Slab model. It can be identified by the HadSM name on the WU.

This model’s graphic say that it runs from 1810 to 2050 (2065 actually, the graphic is wrong), but, it calculates only 45 years in that span in 3 phases. The Phases change at about 33% and 66% At 67% it sounds like you are just finishing Phase 2. Phase 1 runs from 1810 to 1825 and is the pre-industrial baseline phase. Phase 2 runs 1825 to 1840, and is the industrial phase. The model then jumps ahead to 2051 and calculates to 2065. This is the double CO2 phase.

I hope that this helps.

Jim

P.S. The graphic sometimes get screwed up at phase change. If pressing \"T\" or \"C\" doesn\'t help try eiting the manager and restarting it.

Ivanhoe, could you please tell us what your model is doing now.
