Is there a way inside a .cl file to know whether the compiler is provided by NVIDIA or ATI? via a define. Also, is there a way to query which extensions are available from within a .cl file?
I am thinking something like
#ifdef USING_NVIDIA_COMPILER#if HAS_DOUBLE_PRECISION_SUPPORT#define Real_t double#pragma OPENCL EXTENSION cl_khr_fp64 : enable#else #define Real_t float#endif #else #i HAS_DOUBLE_PRECISION_SUPPORT#define Real_t double#pragma OPENCL EXTENSION cl_amd_fp64 : enable#else #define Real_t float#endif
Thank you

ifdef

endif

#i HAS_DOUBLE_PRECISION_SUPPORT

Sure, I do something like that. See section 5.4.3, Build Options. They are passed in with clBuildProgram(). You might have an options argument like:
“-D USING_NVIDIA_COMPILER” or
“-D HAS_DOUBLE_PRECISION_SUPPORT” or
“-D USING_NVIDIA_COMPILER -D HAS_DOUBLE_PRECISION_SUPPORT” or
“”
You will have to query your device at runtime in order know which options arg to pass.
