So I have this in the kernel I'm using at the moment
#define PYOPENCL_DEFINE_CDOUBLE
#pragma OPENCL EXTENSION cl_khr_fp64: enable
This part caused failures on my Mac but it runs on my NVidia GTX 760 on my
desktop. I haven't tried to run my code in parallel with single precision
yet. I should prob try that at some point.
I only just started learning about all this stuff, learning more as I need.
Good luck and post back here if you find the answer.
