Ask HN: Recommendations for High-Performance Multi-threading Libraries in C++?(hn.user)

    I've had great experiences with Intel's TBB library. It's quite mature and easy to use.

  • jane_doe 1 year ago | prev | next

    I'd second that, TBB has been around for a long time and has good documentation and support.

  • jim_brown 1 year ago | prev | next

    If you prefer a more modern approach, you might want to consider C++20's <std::jthread> library.

    • john_doe 1 year ago | next

      I've been reading about <std::jthread>, but I'm still a bit skeptical about its real-world performance.

    • jane_doe 1 year ago | prev | next

      It is worth noting that <std::jthread> is only the tip of the iceberg in terms of C++20's multi-threading capabilities. Things like execution policies and parallel algorithms could prove very useful.

      From my experience, folly's Task library has been quite robust and easy to integrate with existing code.

      • jim_brown 1 year ago | next

        I've also heard good things about folly's Task library, I'll certainly have to give it a try.

  • jane_doe 1 year ago | prev | next

    Whichever library you choose, I'd highly recommend properly benchmarking and testing it with your specific workload. Threading and performance can always be a bit unpredictable.

  • jim_brown 1 year ago | prev | next

    Absolutely, also pay attention to the thread-safety guarantees that each library offers.

    Just curious, but how do you all feel about the use of C++20 Coroutines in multithreading?

    • john_doe 1 year ago | next

      That's an interesting question, I haven't personally tried using Coroutines for multithreading, but I'd definitely be open to learning more.

    • jim_brown 1 year ago | prev | next

      There is a lot of excitement around Coroutines in the C++ world, but I haven't seen a lot of production-ready implementations using it with multithreading yet.

  • jane_doe 1 year ago | prev | next

    I'd be remiss if I didn't mention QSerialServer's ThreadPool library. It's incredibly convenient for I/O-bound tasks.

    • jim_brown 1 year ago | next

      I haven't had the chance to work with asynchronous tasks in a while, I'll make sure to check that out.

  • user888 1 year ago | prev | next

    <std::async> is another option, although it has its limitations.

    • jane_doe 1 year ago | next

      Yes, <std::async> can be a bit limited in terms of configuration and customizability, but it gets the job done for basic use cases.

    • jim_brown 1 year ago | prev | next

      True, for more complex use cases, I'd say go with something like TBB or C++20's <std::jthread>.

    • user123 1 year ago | prev | next

      <std::async> should be avoided whenever possible due to its poor performance characteristics in certain scenarios.

  • john_doe 1 year ago | prev | next

    I'd love to hear about other libraries and experiences. Let's keep this conversation going.
