    cl_khr_fp64 on OpenCL

      cl_khr_fp64 on OpenCL


      I has an ATI HD4870 RV770 and an intel Q8200 processor

      I am on linux ubuntu 9.04 and Ati driver beta installed



      Searching for CL_DEVICE_EXTENSIONS i get for the Q8200

      "cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics cl_khr_byte_addressable_store"


      and the RV770 return an empety string


      Q8200 and RV770 has double support, but the extension "cl_khr_fp64" is not defined

      I am doing something wrong ?
