已经实现了C ++ 17并行算法吗? [英] Are C++17 Parallel Algorithms implemented already?

问题描述

我试图尝试使用C ++ 17标准中提出的新并行库功能，但无法使其正常工作.我尝试使用最新版本的g++ 8.1.1和clang++-6.0和-std=c++17进行编译，但似乎都不支持#include <execution>，std::execution::par或任何类似的版本.

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.

查看并行算法的 cppreference 时，一长串算法，声称

When looking at the cppreference for parallel algorithms there is a long list of algorithms, claiming

技术规范为algorithm，numeric和memory提供了以下69种算法的并行版本:(...长列表...)

Technical specification provides parallelized versions of the following 69 algorithms from algorithm, numeric and memory: ( ... long list ...)

听起来算法已经准备好了，但还没准备好使用吗?

which sounds like the algorithms are ready 'on paper', but not ready to use yet?

在此SO问题中，一年前的答案声称尚未实现这些功能.但是到现在为止，我已经期望看到某种实现.我们已经可以使用任何东西了吗?

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?

推荐答案

您可以引用 https: //en.cppreference.com/w/cpp/compiler_support 来检查所有C++功能实施状态.对于您的情况，只需搜索"Standardization of Parallelism TS"，您将发现仅MSVC和Intel C++编译器现在支持此功能.

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.
