Well I am working on PMPD and particulary on the morphing exemple for a live show in two weeks, my computer (athlon 2600+, 333Mhz bus freq, 512 RAM, and Nvidia 64Mo) can handle the 125 spheres with no problems, it's slowing down if I use text with 'round' fonts and more than two letters, So I could make an emulation of the largest planets (from mercury to pluto-charon) with our sun without problems, but the solar system has more than four hundred thousands planets
Well, please make a distinction between the computation time and the rendering time. Also please take into account that it's pointless to try to display all of them at once, and maybe even 1% of them.
So, a cluster of several computers (maybe with pure-dyne) would be needed to make an accurate model, indeed...
I would reach that conclusion but rather based on the fact that computing gravity is an O(n^2) process, due to the N*(N-1)/2 gravitational interactions that I was talking about. So I wouldn't even take rendering into account here.
Anyway, any rendering I'd do would only involve some objects, because humans can't really track 400000 objects on screen, even with the biggest-ass monitors possible (normal screens don't have nearly enough pixels).
