Which is the better computer specifications to run this kind of code?

in General Discussion • Other • 10 months ago

Hello all,

I'm working on a project to simulate galaxies (a lot of stars). I want to display a maximum of particles (optimal will be 2*10^6). So I have to buy a new computer for this experiment, I need your knowledge about Processing and computer components efficiency.

There is an example of the kind of code I use: GalaxyTest

(The code could be improve to get more particles with a correct frame rate, but my question is about the computer specifications to run this kind of code with a maximum of particles.)

I guess CPU do the most of the job in this program. (True?)

Did a height cores processor is better than a four (or dual) to run processing program like this one?

(or Processing don't use multi core?)

About GPU for this kind of low graphics simulation?

(so if processing did not deserve big graphic card which one is actually the good buy choice?)

Finally did I need a lot of RAM?

Did I forget something? (SSD or HDD does not matter no?)

Thank you for your time.

Feel free to ask, if you don't understand something.

Cheers.

I can be wrong, but 2 millions of particles isn't that memory intensive... Any modern computer will have enough memory for this. 4 GB is good, better aim at 6 or 8 GB today.
CPU power is important, but to my knowledge, Java / Processing won't use them intensively, unless you start new threads in your simulation. A quad-core can be good. Again, quite common these days. If you manage to parallelize the algorithm over several threads (not an easy task), you can aim at a 8 core.
The graphics card can be critical though: you want to use OpenGL to manage these particles (there are at least one thread about managing particles with OpenGL / GPU), otherwise display performance will be very poor.
