Concurrency control algorithms

resource allocation and deadlock avoidance algorithm

concurrent programming algorithm for mutual exclusion

the first known correct solution to the mutual exclusion problem in concurrent programming

concurrency control method commonly used by database management systems

In software engineering, a spinlock is a lock that causes a thread trying to acquire it to simply wait in a loop ("spin") while repeatedly checking whether the lock is available. Since the thread remains active but is not performing a useful task, the use of such a lock is a kind of busy waiting. Once acquired, spinlocks will usually be held until they are explicitly released, although in some implementations they may be automatically released if the thread being waited on (the one that holds the lock) blocks or "goes to sleep".
