Apple's OpenGL+OpenCL Test App: Galaxies

[SJ_UnderWater]

Apple includes an example app with Xcode's documentation called Galaxies, which performs an NBody simulation (many planets/stars' gravitational fields interacting) using OpenGL for placement and display, and OpenCL to calculate the forces acting on each object for each update. The result is a good informal test of the OpenCL devices on a given system, and their relative power. Since CPU cores are OpenCL devices too, the simulation can run on a single CPU core, all CPU cores, or a GPU.

I've made a few modifications to the source to clean some things up and make it a little more modern/friendly, including giving the controls before the simulation starts. Press Cmd-Q at any time to quit.

the app. only works with Mountain Lion?

Hmm, my updates per sec are pitiful on my 6670 compares to everyone else so far, though it didn't do too bad on the first number. I was getting 8 updates per sec, and around 162 gigaflops. ><
