4. Concurrent data structures

Concurrent data structures are data structures that can be safely accessed by multiple threads at the same time. This is in contrast to traditional data structures, which are designed to be accessed by only one thread at a time. Concurrent data structures are essential for writing multithreaded programs, which are programs that can take advantage of multiple cores in a modern CPU.

5. Lock-free programming

Lock-free programming is a type of concurrent programming in which no locks are used to protect shared data. This can improve performance and scalability, as locks can introduce contention and overhead. However, lock-free programming is also more difficult, as it requires careful reasoning about the order in which operations are performed.

6. Herlihy-Wing queue

The Herlihy-Wing queue is a lock-free queue, a data structure that allows multiple threads to safely enqueue and dequeue elements concurrently. It was developed by Martin Herlihy and Jeannette Wing in 1990. The Herlihy-Wing queue is notable for its simplicity and efficiency, and it has been widely adopted in multithreaded programming.

The Herlihy-Wing queue is based on the concept of a compare-and-swap (CAS) operation. A CAS operation takes three arguments: a memory location, an expected value, and a new value. If the value at the memory location matches the expected value, the CAS operation updates the memory location with the new value and returns true. Otherwise, the CAS operation fails and returns false.

The Herlihy-Wing queue uses a CAS operation to implement a lock-free queue. When a thread wants to enqueue an element, it first allocates a new node in memory. It then uses a CAS operation to atomically update the tail pointer of the queue to point to the new node. If the CAS operation succeeds, the thread has successfully enqueued the element.

When a thread wants to dequeue an element, it first reads the head pointer of the queue. It then uses a CAS operation to atomically update the head pointer to point to the next node in the queue. If the CAS operation succeeds, the thread has successfully dequeued an element.

The Herlihy-Wing queue is a highly efficient lock-free queue. It is simple to implement and has low overhead. It is also scalable, as it can be used to implement queues of any size. The Herlihy-Wing queue is widely used in multithreaded programming, and it is an essential component of many high-performance multithreaded applications.
