Products that do what C discrete event SIM w stackful coroutines runs 45x faster than SimPy does

Hi all, I have built Cimba, a multithreaded discrete event simulation library in C. Cimba uses POSIX pthread multithreading for parallel execution of multiple simulation trials, while coroutines provide concurrency inside each simulated trial universe. The simulated processes are based on asymmetric stackful coroutines with the context switching hand-coded in assembly. The stackful coroutines make it natural to express agentic behavior by conceptually placing oneself "inside" that process and describing what it does. A process can run in an infinite loop or just act as a one-shot customer…
