Antonio Sanchez 45e67a6fda Use reinterpret_cast on GPU for bit_cast. ... This seems to be the recommended approach for doing type punning in CUDA. See for example - https://stackoverflow.com/questions/47037104/cuda-type-punning-memcpy-vs-ub-union - https://developer.nvidia.com/blog/faster-parallel-reductions-kepler/ (the latter puns a double to an `int2`). The issue is that for CUDA, the `memcpy` is not elided, and ends up being an expensive operation. We already have similar `reintepret_cast`s across the Eigen codebase for GPU (as does TensorFlow).		2021-10-20 21:34:40 +00:00
