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.

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.

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.

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

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

<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.

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