我试图尝试使用 C++17 标准中提出的新并行库功能，但我无法让它工作.我尝试使用 g++ 8.1.1 和 clang++-6.0 和 -std=c++17 的最新版本进行编译，但似乎都不支持 #include 、std::execution::par 或任何类似的东西.
I was trying to play around with the new parallel library features proposed in the C++17 standard, but I couldn't get it to work. I tried compiling with the up-to-date versions of g++ 8.1.1 and clang++-6.0 and -std=c++17, but neither seemed to support #include <execution>, std::execution::par or anything similar.
在查看并行算法的 cppreference 时，有一长串算法，声称
When looking at the cppreference for parallel algorithms there is a long list of algorithms, claiming
技术规范提供了来自algorithm、numeric和memory的以下69种算法的并行版本:( ... long list...)
Technical specification provides parallelized versions of the following 69 algorithms from
algorithm,numericandmemory: ( ... long list ...)
听起来算法已经纸上"，但还没有准备好使用?
which sounds like the algorithms are ready 'on paper', but not ready to use yet?
在这个SO问题中一年前，答案声称这些功能尚未实现.但到现在为止，我本来希望看到某种实现.有什么我们可以使用的吗?
In this SO question from over a year ago the answers claim these features hadn't been implemented yet. But by now I would have expected to see some kind of implementation. Is there anything we can use already?
可以参考https://en.cppreference.com/w/cpp/compiler_support 检查所有 C++ 功能实现状态.对于您的情况，只需搜索Standardization of Parallelism TS"，您会发现现在只有 MSVC 和 Intel C++ 编译器支持此功能.
You can refer https://en.cppreference.com/w/cpp/compiler_support to check all C++ feature implementation status. For your case, just search "Standardization of Parallelism TS", and you will find only MSVC and Intel C++ compilers support this feature now.
