Implementation of a multithreaded compile-time ECS in C++14
summary
A compile‑time, multithreaded ECS called ecst runs in C++14 and uses Boost Hana–style metaprogramming, a thread pool plus latch synchronization, a sparse integer set for IDs, and policy‑based storage/layout choices. It parallelizes systems and subtasks automatically, handles deferred entity creation to avoid locks, and drives a 50,000‑particle demo at about 50 FPS on an old machine. Source and slides show the implementation and practical performance tradeoffs.
