Hi I have check the error, for some card, yes, just like what I said above, some cards does not support double type, so we must check the opencl extension: cl_khr_fp64 before the kernel compile. If the device support, we use GPU, else, we use CPU or use float type, Is it OK?Thanks Best regards
Of course, if there's a way to only fall back to floats if doubles are not available, that'd be preferable.
