I have a Cayman card which I would like to use for double-precision computations. According to clinfo, cl_amd_fp64 is supported, but cl_khr_fp64 is not.
- What is exactly the difference betwen the two fp64? The document at khronos http://www.khronos.org/registry/cl/extensions/amd/cl_amd_fp64.txt is uninformative.
- Is cl_khr_fp64 going to be supported in a future version of the SDK for the Cayman hardware?
