I have just tried to run an official OpenCL sample program by Apple on a MBP 10.6.3 machine. Result: a crash. Why? I do not know yet, but it seems that OpenCL somehow crashlanded the nvidia OpenGL driver. This is what I get:
08.04.10 17:04:50 kernel NVDA(OpenGL): Channel exception! exception type = 0xd = GR: SW Notify Error
08.04.10 17:04:50 kernel 0000006e

As soon as I know something more and especially how to fix it, I will share it here.
Update: It does not crash, if I don’t touch any keys when the kernel runs. So I guess the OpenCL drivers are a bit buggy still…
