Subject: Re: [oc] Newbie question - matricies and vectors for physics
Check out the gpgpu site , ( gogle a little ).
Basicly the modern graphics cards, ( latest ati and nvidia ), supports
arbitrary math on square matrices, this can be totally programmed in
opengl( 2.0 preferably ), at 32 bit floating point.
Thus a CML or LBM simulation can run at 100-500 fps in the graphics
card, ( thus simulating fx. a fluid, or any PDE ).
So if you wan't to solve PDE's really really fast, you can get about
16 GFLOPS out of a graphics card at 32 bits.
I hope this is a little pointer for you and some solid help, also you
can run examoles and such using a software emulator.
/ regards, Lars Segerlund.
