A dual 2.5 Mac (10.4.3), the application library installed installed and the latest BOINC (5.2.13) downloaded. A sulphur unit downloaded, and apparently running well, though faster and faster (going from 3 to 2 seconds for a TS). But the planet is blue, as it has been on every previous version on this machine when the graphics have worked. Should I abort this, and try another? Scrub all my existing folders and start again? Give up? In a year I still have not completed an entire workunit.

I would just let it run if I were you and it may resolve itself in time. It may not have enough information yet to build a display.

Have you read this section:-

http://www.climateprediction.net/AdvancedVisualisation/advancedvisualisation_intro.php


There is information on Mac there, and it will explain how the display works.

And the next sulphur unit as well; totally blue, which I think means cold, and perhaps means no data.

Thanks, Knightrider, for the reference. It seems that the sulphur experiment needs version 3 of the visualisation software, which is not currently available for Macintosh. I\'ll be patient, and let them run.

Hi there,

I had this problem in one model before, too, on a Dual 1,25 GHz Mac under 10.4.3. It occurred after I once had stopped the BOINC client without before quitting the graphic clients for the two models I ran.

If you once started the common visualization tool (be it in the client by clicking \"work -> graphics\" or by enabling the screen saver), you should have several icons in the dock: One for the BOINC client (showing the yellow B on blue background) and one for each graphic client used for visualization before (these show a globe with, like a puzzle, a little white piece missing in the lower right corner).

If you want to stop the BOINC client, e.g. for rebooting the machine, first right-click the visualization icons and stop them. On my machine, this also pauses calculation of the models for a moment, which then starts again on its own. Stopping the whole client without first stopping the visualization crashed one of my planets, it froze to -42°C without rain or clouds or pressure, blue world like your\'s.

By the way: Running the visualizations eats up a remarkable share of CPU time, though I like playing around with these globes, too.

HTH,
ajo

That\'s odd. Is it the same for every field. ( clouds, pressure, precip )
have you tired running the standalone version.
i.e sulphur_gfx*

> By the way: Running the visualizations eats up a remarkable share of CPU time.

The gfx cpu utilisation capped at 20%. You can change this on your user prefs page amongst other
things.

This was actually intended to be a globe with clouds around it. (highlights my artistic skill : or lack thereof)
If there are any graphics artists out there able to do something better, we\'d be very grateful.

PS: please be patient. I\'ll make available a new Advanced Visualization on all platforms.

It seems to be the same for every field except that toggling snow causes white patches to appear and disappear.

Now I have. The results are the same as with the graphics in Boinc Manager, except that the standalone version doesn\'t know who the user is.

Hi there,

though I have posted some quite critical messages, I didn\'t mean my last one to be a really critical one. On my machine, everything is running smoothly right now. I sometimes watch the turning globes, but I can also stop the necessary graphic clients and (after that) even may reboot the machine without problems: The models start running by themselves again.

It seems to me, there are some (to me: minor) limitations to run CPDN on Mac, but after I was able to identify them, I see a perspective. I will run the two models present on my two CPUs until they finish. Because I want to support this.

I lost the previous two sulphur units through a restart. Now I have a new one. After a few hundred timesteps, it looked like a normal globe with temperatures, pressure and so on. But now after 3000 or so timesteps, it is the same as the others, totally blue, with nothing in any field except for the snow toggling effect.
