void foo(cuda::std::optional<int>);If another library, libB.so, is compiled using CCCL version Y and uses foo from libA.so, then this can fail if there was an ABI break between version X and Y. Unlike with API breaking changes, ABI breaks usually do not require code changes and ...

Instead, it simply returns a std::vector<std::optional<cudaStream_t>>, which is a vector of size equal to the number of messages on the input port. Each value in the vector corresponds to the cudaStream_t specified by the message (or std::nullopt if no stream ID is found). Note ...
Specifying a stream for a kernel launch or host-device memory copy is optional; you can invoke CUDA commands without specifying a stream (or by setting the stream parameter to zero). The following two lines of code both launch a kernel on the default stream. ...

确保你的系统上安装了支持CUDA的C++编译器,如GCC或Clang。同时,你也需要安装CUDA Toolkit,它包含了编译CUDA代码所需的工具和库。 编写CUDA C++ 17代码: 编写你的CUDA C++代码,确保它使用了C++ 17的特性。例如,可以使用std::variant、std::optional等C++ 17的新特性。 配置编译器选项以启用C++ 17支持: 在你的C...
