# map_f64_to_f32 how do I enable this?

Hi,

I have an OpenCL program that runs on a GTX280, GTS260 and GTS450, but on a GTS 250 I get the following error.

… requires SM 1.3 or higher, or map_f64_to_f32 directive.

I guess OpenCL does not have a map_f64_to_f32, so I tried

pragma OPENCL EXTENSION cl_khr_fp64 : enable

but I still get the above error message. What OpenCL directive corresponds to map_f64_to_f32?
