1) Questions and Answers : Windows : Using Boinc/Climateprediction in science-class (Message 30493)

There are also the SAP models (HadAM3) from http://attribution.cpdn.org which take about 2 weeks to run (and have more detailed graphics because it\'s a high resolution model).

However I wouldn\'t recommend running them on a machine with less than 1GB of RAM (SAP uses up to 450MB, whereas Slab only uses 48MB of RAM).


Thanks for info. Started up a SAP-model from CPDN today. It reports to run about 530 h. First i would´nt start (reported lack of hard disk memory), but after some time it started ok. I tried to find the team I defined on climatepredicteion.net, but could´nt find it. Had to define a new team on CPDN. I like the idea with teams since I can define teams with my two classes competing to each other. Probably I will start up with my students next week with the SAP-model since we have 2G of internal memory.

Hi

I´m teaching in a science-class (students age 16) in Sweden. The classes will be for one semester (5 months). The question about global warming could be well illustrated by setting up a climateprediction project. The student have their own laptops and my idea is to have them run climateprediction. The class could work togehter as a team and would compete against other classes (I´m doing this in two classes). We also could arrange a competition against other school i Sweden or Europe.
But - because of short time (5 months) the model would probably not be run completly. If we start up about 60 clients, but none is completed (maybe 50%) - will this anyhow contribute to any useful information for the main project? Or do you have any other suggestions how to use climateprdicition as a student project? Thanks for any comments.

Is it possible to move a project that has run for about 210h (5,4%) to an new computer? (It feels waste of time just to dismiss the job done and load a new project)

The current models are producing the data that the researchers need.
What smaller tasks did you have in mind?



Well - is it possible to distribute tasks that are smaller, lets say about 10h on a regular computer, intead of about 2500 h?

The Climateprdciction client running om my computer reports at the moment 40,3 h completed and 2596 h remaining time. 1.31% of job is completed. This number does not make sense. If 1.312% equals 40h, the total running time would be mor than 3070 h. becaause the job takes so long time it would be a problem to finish the task. What calculation shall I relay on? Why not distribute smaller tasks?
