Offering a simpler way to conceptualize https://en.cppreference.com/w/cpp/atomic/memory_order

  1. Every atomic object has a timeline (TL) of writes:

    • A write is either a store or a read-modify-write (RMW): it read latest write & pushed new one.
    • A write is either tagged Relaxed, Release, or SeqCst.
    • A read observes some write on the timeline:
      • On the same thread, future reads can't go backwards on the timeline.
      • A read is either tagged Relaxed, Acquire, or SeqCst.
      • RMWs can also be tagged Acquire (or AcqRel). If so, the Acquire refers to the "read" portion of "RMW".

  2. Each thread has its own view of the world:

  • Shared write timelines but each thread could be reading at different points.
