From the creator of Atom's web page: """ Atom Atom is a Haskell DSL for designing hard real-time embedded software. At Eaton, we use it for automotive control systems. Based on guarded atomic actions, and similar to software transactional memory, Atom enables highly concurrent programming without the need for mutex locking. In addition, Atom performs compile-time task scheduling and generates code with deterministic execution time and constant memory use, simplifying the process of timing verification and memory consumption in hard realtime applications. Without mutex locking and run-time task scheduling, Atom can eliminate the need and overhead of RTOSs for many embedded applications. """
