boost:asio thread pool implementation for occasionally synchronized tasks

Question

I have a \"main\" function that performs many small, independent tasks each once per time step. However, after each time step, I must wait for all of the tasks to complete befor

Answer 1

may be you can use boost::barrier as follow:

void thread_proc( boost::barrier& b ) {
    while( true ) {
        if( !ioservice.run_one() ) break; // io_service stopped
        b.wait();
    }
}
