Why can't I simply overload the half and float constructor in some header file in cuda, to add the previous intrinsic like that : float::float ( half a ) { return __half2float ( a ) ; } half::half ( float a ) { return __float2half ( a ) ; }

WebOct 13, 2015 · Like other such CUDA intrinsics starting with a double underscore, __float2half () is a device function that cannot be used in host code. Since host-side conversion from float (fp32) to half (fp16) is desired, it would make sense to check the host compiler documentation for support.

WebJul 15, 2015 · As noted in the CUDA C Programming Guide, the bit layout of ‘half’ operands on the GPU is identical to the 16-bit floating-point format specified by IEEE-754:2008. As mentioned, CUDA does not provide any arithmetic operation for ‘half’ operands, just conversions to and from float. WebAug 28, 2016 · There is support for textures using half-floats, and to my knowledge this is not limited to the driver API. There are intrinsics __float2half_rn () and __half2float () for converting from and to 16-bit floating-point on the device; I believe texture access auto-converts to float on reads.

WebMay 21, 2012 · To avoid code duplication, CUDA allows such functions to carry both host and device attributes, which means the compiler places one copy of that function into the host compilation flow (to be compiled by the host compiler, e.g. gcc or MSVC), and a second copy into the device compilation flow (to be compiled with NVIDIA’s CUDA compiler).
