So in your case you should wait for a condition (for example boost::condition_variable) to indicate end of tasks.So using this technique it is very easy to implement it using boost::asio and boost::condition_variable. Web9.1.1. The simplest possible thread pool. At its simplest, a thread pool is a fixed number of worker threads (typically the same number as the value returned by std::thread::hardware_concurrency ()) that process work.

WebApr 6, 2024 · The OpenMP way is more complicated- it cuts the problem into many small sized chunks (of 8 in my example), and then uses work-stealing scheduling to give these chunks to threads in a thread pool. The difficulty of implementing the OpenMP way, is that you need "persistent" threads that wait for work ( a thread pool ). Hope this makes sense.
