um.. I was planing on running everything on an HP Pavilion Entertainment PC laptop.
I assume it has only one core, and I certainly don't know how to hook up other ones, though I know people who surely do. how many cores do you folks usually use? am I fighting what must surely be a loosing battle, my goal being to simulate up to 1 million particles (1 cubic millimeter glass beads in a volume of about 1 liter), for at least 4-10 seconds? 10 000 particles? 1000? but I can do those calculations. and doing simulations that last months.. jesus! they must be important.. :-D --- On Thu, 7/8/10, Janek Kozicki <[email protected]> wrote: From: Janek Kozicki <[email protected]> Subject: Re: [Yade-users] hello? -help with a spinning bucket!

The optimal number of cores depends on how many particles you have. It could be, that with few particles, the simulation is actually slower with more cores. Do some trials, and run your simulation with less or more cores, and see which one gives you most iterations per second. You can control the number of cores to be used with -j switch: `yade -j3` will use three cores. -- Janek Kozicki http://janek.kozicki.pl/ | _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
