Per NVRTC doc - https://docs.nvidia.com/cuda/nvrtc/index.html#accessing-lowered-names, we can compile a templated kernel (e.g. `kernel<float>`) with the following steps NVRTC side - (new) `nvrtcAddNameExpression` -> C++ template e.g. `f<float>` - `nvrtcCompileProgram` - (new) `nvrtcGetLoweredName` -> get mangled name. need to do a copy since later this string is freed after NVRTC program is destroyed - `nvrtcDestroyProgram` CUDA side - use mangled name instead of normal name -> profit - `extern "C"` is not even needed Pull Request resolved: pytorch#162875 Approved by: https://github.com/msaroufim
