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> ID: 15011 · Reply Quote

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 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.
