Visual Studio 2026可选并行编程方案汇总
Table of Contents
传统线程模型（C++11）
std::thread t([]{ work(); });
std::mutex m;
线程层 - 现代线程模型
std::jthread t([](std::stop_token st){
while (!st.stop_requested()) { work(); }
});
异步逻辑 - C++20 协程
task<int> foo() {
co_await async_io();
co_return 42;
}

(MSVC) Build Tools
Version 18.0 of the IDE ships with Microsoft C++ (MSVC) Build Tools version 14.50
Visual Studio 2026（MSVC v14.5x）
VS 2026 多核 CPU 并行计算
#底层
std::jthread + std::stop_token
#中层
固定线程池（= CPU 核数 or 核数-1）
#上层
任务并行（task graph / DAG）
大数组并行计算
pool.submit([=]{ compute_block(i); });
size_t cores = std::thread::hardware_concurrency();
ThreadPool pool(cores);
for (size_t i = 0; i < cores; ++i) {
pool.submit([&, i] {
process_chunk(i);
});
}
pool.wait();
How to use
build with /std:c++latest or go with /std:c++23preview if you only need features up to and including C++23.
C++26 标准委员会正在推进，MSVC 逐步跟进
通过 /std:c++latest 开关可以尝试使用部分 C++26 草案特性
VS2026（MSVC v14.50 + /std:c++23 或 /std:c++latest）
