Hi! I have two different climate models running on my computer (accidentaly I attached to a project a second time), each taking up about 50% of the processor power (when nothing else is being used). One averages 3.37 s/Ts the other 3.44 s/Ts. Is this difference due to the way my processor assigns processor power to the first process preferentially, or do the varation of the parameters within the models cause the difference in speed? Just curious... |

Different parameters result in different calculation times. |

On my two HT CPUs slot 0 is always faster than slot 1, on my limited comparison of running my first 6 models. |

If you watched the picture globe of one model preferentially, or left one on accidentally overnight, that would be enough to make a difference. __________________________________________________ |
