does this seem correct? |

Pentium 3.2 GHZ HT, two concurrent models: two trickles a day, around 24 hours per trickle for each model (one trickle every model year or .625%). Quite normal, though some overclocked machines do better. This is a demanding time-consuming, project. Forum search Site search |

My P4 HT 2.4G takes about 220 days to complete a unit. My 2.13G Core 2 Dual will take about 85 days to complete a unit. Yes, it\'s normal. You are doing weather calculations for a 160 period of time. |

OK. Thanks, I\'ll keep at it. Though I wish it\'d send the first credit request. I\'d feel a lot happier then. Cheers folks |

You\'ll probably feel unhappy again when you find out that there can up to a 1 day lag between the trickle being sent, and the credit program being run. And don\'t forget that trickles are to sent back science data for the just-run year. Backups: Here |

This runs sometime between 04:00UTC and 10:00UTC (usually when I am in bed). Good job so far! Your t/s speed is right on the mark. |

I too was surprised at the amount of processing time needed, i thought only small chunks of data would be sent and processed within a week. I\'ve got a p4 2.4ghz with 512mb, its saying 70days to to a hadcm3i project. Now that i assume i\'ve downloaded the project, can i disconnect from the internet at any time and turn off my computer periodically? Or do i have to stay online to get these \"trickles\" sent? thanks orfeo OK. Thanks, I\'ll keep at it. Though I wish it\'d send the first credit request. I\'d feel a lot happier then. |

You can disconnect from the internet and the trickles will be stored ready to send all together when you do connect. But if you don\'t connect to he internet for 6 weeks the server will think you\'ve abandoned the model. You\'d still be able to continue it, but the server might then also give the model to another computer. Have a look at the project READMEs in my signature, particularly about how to back up just in case the model should crash. A model crash is always a risk because the models last so long. Cpdn news |
