Wait-freedom Wait-freedom means that each thread moves forward regardless of external factors like contention from other threads, other thread blocking. Below is an example of a wait-free algorithm: void increment_reference_counter(rc_base* obj) atomic_increment(obj->rc); void decrement_reference_counter(rc_base* obj) if (0 == atomic_decrement(obj->rc)) delete obj; Each thread is able to execute the function in a bounded number of steps regardless of any external factors. Lock-freedom Lock-freedom means that a system as a whole moves forward regardless of anything. An example of a lockfree algorithm is: void stack_push(stack* s, node* n) node* head; do head = s->head; n->next = head; while ( ! As can be seen, a thread can "whirl" in the cycle theoretically infinitely. Obstruction-freedom Termination-safety Blocking Algorithms Practical Implications 1. 2. 3. Performance/scalability
