-// You may be wondering: Whose brilliant idea was it to split torch_cuda into
-// two pieces with confusing names?
-// Once upon a time, there _was_ only TORCH_CUDA_API. All was happy until we
-// tried to compile PyTorch for CUDA 11.1, which ran into relocation marker
-// issues when linking big binaries.
-// (https://github.com/pytorch/pytorch/issues/39968) We had two choices:
-//    (1) Stop supporting so many GPU architectures
-//    (2) Do something else
-// We chose #2 and decided to split the behemoth that was torch_cuda into two
-// smaller libraries, one with most of the core kernel functions (torch_cuda_cu)
-// and the other that had..well..everything else (torch_cuda_cpp). The idea was
-// this: instead of linking our static libraries (like the hefty
-// libcudnn_static.a) with another huge library, torch_cuda, and run into pesky
-// relocation marker issues, we could link our static libraries to a smaller
-// part of torch_cuda (torch_cuda_cpp) and avoid the issues.
