Lightning Talk: Making Friends With CUDA Programmers (please constexpr all the things)
summary
Claim: nvcc’s --expt-relaxed-constexpr lets constexpr functions run on device so libraries don’t need __device__ everywhere. Demo builds a hello GPU, replaces a device square with constexpr and it runs. Passing a std::array into a kernel computes a cumulative sum but initially fails calling operator[] until compiling with a newer C++ standard that makes operator[] constexpr. Also shows using Boost.Rational (constexpr) and a chart of growing constexpr usage.
