PowerMacs G5 for climate simulation needed


The destruction of New Orleans by hurricane has shown the importance of climate for life on our planet. The distributed-computing-project "www.climateprediction.net" tries to explore our climate and its changes in the near future.


Sulphates act to scatter solar radiation and reduce the amount of solar energy reaching the surface. The reduction in solar radiation cools the surface and reduces the warming effect caused by greenhouse gases. So, a prediction of the climate in the 21st century needs to contain the effects of sulphate aerosol. Otherwise the warming trend may be overestimated. This is called the 'global dimming' effect. Therefore the Oxford university in Great Britain created a special "sulphur cycle experiment" within the "climateprediction"-project.

From this experiment it is hoped that scientists will be able to better understand the range of uncertainty in climate models due to the parameters in the sulphur cycle. This information will then be used in the following experiments of climateprediction.net.


The project has just released a special MacOSX-client for the "sulphur cycle experiment", which is very crunch-intensive and needs powerful Macs in order to be completed successfully. On a P4 3.0 in Linux, running stand-alone, one Sulphur Cycle Model requires approximately 39 days (@24/7). Therefore exspect an uptime of 35 up to 60 days for a PowerMac G5 to complete just one Sulphur cycle model. Moreover you will need a quick internet connection to do the upload and download of project files.
Exspect about one gigabyte datas to be downloaded on your harddisk during the whole run and about 20 megabytes datas which have to be uploaded. The datas of the experiment will need up to three gigabytes volume on your harddisk.

This is only a job for powerusers who want to demonstrate the power of the most modern Apple technology and their real interest in the future of mankind.

Sorry, macdude, but distributed computing projects like cpdn don't have any commercial values.
I am acting as a private Apple fan who is interested in climate simulations and searches for Apple-powerusers interested in my hobby too.
Unfortunately an Apple II doesn't have enough cpu-Power to take part in the project.

1. Spam <> Commercial products, ideas, or programs.

2. Don't make fun of my Apple IIe Platinum.

1. No problem.
2. Don't make fun of the "sulphur cycle experiment".

P.S. If you don't have a PowerMac G5 but Pentium 4 3000 or AMD 64 3000+ and better you're welcome too.

who cares about climate simulation? if it works,then next time we'll just know WHEN new orleans will flood. i think macdude is right ... its spam.


especially since you only joined the forum to post the advertisment for it....

Feel free to believe whatever you like.

Why does it have to be G5? Just curious... It sounds alot like a F@H project if you ask me.
If this is so important, perhaps you should contact whoever's in charge of that Virginia University Super Computer 1000+ X-Serve G5's...

Hmm?

I mean, as far as I know, we don't have any G5 users here. (at least none that I know of)

[ulenz]

X-Serve G5 are always welcomed !
