Designing for Concurrency Using Message Passing in C++ - Anthony Williams - C++ on Sea 2023

[@widnyj5561]

The problem with message based concurrency that relies on OS mechanisms (either network based or kernel based like pipes, MQs) is a system call. And a hidden cost of this (since meltdown and spectre) is a cache clear - which can hurt your app. It may be acceptable trade off, but you need to be conscious of that

[@sirnawaz]

You can have in-process message-queues as well, like channels in golang, or mpsc in Rust. These are fast and quite helpful.

Looks like the Actor model.

[@simonfarre4907]

Yes because the actor model is built on message passing.
