Default OpenCL (CPU + GPU) Benchmark

Here I would like to show the HardwareCanucks Forum the benchmark I wrote in C# and OpenCL. The algorithm consists of calculating the orbital trajectory of 1000000 rocks around a sphere in space using Kepler's laws of planetary motion and the formula of an ellipse. The is in loop which repeats itself 1000 times. The benchmark can both be executed on the CPU and GPU. The CPU and GPU benchmarked are multi-threaded.

If enough people show interest in this benchmark then I will create a highscore list. Please post your results with a screenshot of the results.

I have a Radeon HD 5870 GPU and the GPU benchmark currently does not work on my GPU. I am using the Catalyst 11.4. The benchmark might work with an earlier driver and the AMD Stream SDK. Geforce users should have no problem executing the GPU benchmark as long as their GPU driver is up to date.

Here is my result for the CPU benchmark.

VERY cool.

The issue may be the change from AMD's Stream to the AMD APP platform though. Have you tried their newest SDK?

Crashes when I try to run the GPU benchmark. Have updated drivers.
I couldnt think of something snarky or interesting to put here this time around.
