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.
