Cuda half2float
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. WebNov 27, 2024 · I'm trying to compile the code on my Ubuntu 18.04 LTS machine, with cuda=10.2, Nvidia driver version=440.33.01. I suspect the code is not compatible with cuda 10. Cuda 9 is not officially supported on Ubuntu 18.04 so I cannot test the co...
