Cuda half2float
WebApr 7, 2024 · I did some research and it appears half2float is a CUDA library function. In fact I'm not even using it directly in my code. It's likely included from certain headers. So I dunno how this multiple definition thing come into play, and thereafter how to fix this problem. A few snippets from my code can be seen from this gist. 1 WebMar 24, 2016 · However, it seems that there are intrinsics in cuda that allow for an explicit conversion. 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 ) ; }
