我想知道是否有一种简单直接的方法可以在 C++ 中并行计算诸如 for
和基于范围的 for
循环之类的循环.你会如何实施这样的事情?我从 Scala 知道 map
、filter
和 foreach
函数,也许也可以并行执行这些函数?有没有一种简单的方法可以在 C++ 中实现这一点?
I wonder if there is a light, straight forward way to have loops such as for
and range based-for
loops compute in parallel in C++. How would you implement such a thing? From Scala I know the map
, filter
and foreach
functions and maybe it would also be possible to perform these in parallel? Is there an easy way to achieve this in C++?
我的主要平台是 Linux,但如果它可以跨平台工作就好了.
My primary platform is Linux, but it would be nice if it worked cross-platform.
借助 C++17 中的并行算法,我们现在可以使用:
With the parallel algorithms in C++17 we can now use:
std::vector<std::string> foo;
std::for_each(
std::execution::par_unseq,
foo.begin(),
foo.end(),
[](auto&& item)
{
//do stuff with item
});
并行计算循环.第一个参数指定执行策略
to compute loops in parallel. The first parameter specifies the execution policy
