The FluidSimulation2D and Mandelbrot OpenCL samples (under the x86_64 folder) hang the computer after 1 to 5 seconds of execution on the GPU. This is always reproductible. Execution on the CPU work fine. Those two samples work fine on the GPU again when I reinstall the previous AMD APP SDK V2.2. So I suspect a bug in the version 2.3 of the SDK. I have not tested other sample.
Since the FluidSimulation2D sample is only available with the version 2.3 of the SDK, I have saved the binary in another folder to be able to execute it with version 2.2.
Here is the system configuration:
