Buddhabrot animation using OpenCL

It was rendered using OpenCL on two Teslas. I know, I know... what a waste of hardware but I wanted to test them.

The problem is not very well suited for OpenCL but even without Metropoli-hasting the GPUs outperformed the CPU.

Here it is a link to more highres screenshots and to the source code (Java + LWJGL). http://www.infinityk.com/buddhabrot-rendered-using-opencl/

The first half of the video is kind of boring, only playing with the transfer functions. In the middle part I render only orbits which certain scape iterations, and in the last part a render of the low scape iterations orbit is shown (but changing the exponent value).

often times... there are other approaches which are kinda crappy until you put them in the context of parallel machines

"The problem is not very well suited for OpenCL but even without Metropoli-hasting the GPUs outperformed the CPU."

Even my ati 4350 outperforms my cpu (athlon 64 x2) when it comes to opencl performance (with around a factor 3 in fractal renders), no wonder you can do the same trick with 2 tesla's. I'm currently on a opencl renderer as well, 2d fractals already work, hope to get the first mandelboxes out next week.
