Running a P4 2.4Ghz with 1gb of ddr ram at work and its eta on completion is 700hrs after doing 1%... surely this cant be accurate? |

Your P4 is registered as 2.0GHz, and 700 hours sounds about right to me. CPDN results are very computationally intensive, but they trickle results back to the scheduler every 10802 timesteps. There are 259284 timesteps for each of the 3 phases, so trickles are returned every 1.39% or so. <br><a href="http://www.teampicard.net/"><img src="http://www.teampicard.net/images/picardmini.gif"></a><a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/team_display.php?teamid=3">Join us here</a> |

What can I do to tweak this....? |

You could run two models, they\'ll take slightly longer to run individually but you\'ll get nearly twice as much work done overall in the same time. Dual cores rock... I'm a volunteer and my views are my own. News and Announcements and FAQ |

i have only been doing this a very short while but i am running a pentium 4 2.8ghz dual core processor and 1gb of ddr2 ram and it says i have 2934 hours to complete and has given me a year to do it. it has also used 700mb of hard drive space is this a really big one that i have been given or is it just my computer and the lack of time i have been doing it |

That sounds roughly right, although you may find the time estimate is an overestimate (it\'s based on the Boinc benchmarks, which are frankly useless). I have an P4 820 D which runs two models, taking around 2,500 hours to finish them in tandem. The disk space won\'t increase unless something crashes. I'm a volunteer and my views are my own.
