A header-only thread pool for C++

cxxpool

Version: 2.0.0

cxxpool is a header-only thread pool for C++. It enables you to schedule independent tasks with or without specifying task priorities. Pushing a task into the thread pool returns a future associated to the underlying execution.

cxxpool is designed for ease of use, portability, and scalability. It is written in C++11 and only depends on the standard library. Just copy src/cxxpool.h to your project and off you go! Tested with GCC, Clang, and Visual Studio.

Example

This example creates a thread pool with 4 threads and pushes three simple tasks into the pool.

#include <iostream>
#include "cxxpool.h"

int sum(int x, int y) {
    return x + y;
}

int main() {
    cxxpool::thread_pool pool{4};

    // pushing tasks and retrieving futures
    auto future1 = pool.push([]{ return 42; });
    auto future2 = pool.push([](double x){ return x; }, 13.);
    auto future3 = pool.push(sum, 6, 7);

    // output: results = 42, 13, 13
    std::cout << "results = " << future1.get() << ", ";
    std::cout << future2.get() << ", " << future3.get() << std::endl;
}
