With large numbers of processors, adding a random exponential backoff delay before re-checking the lock performs even better than TTAS. [4] [5] A few multi-core processors have a "power-conscious spin-lock" instruction that puts a processor to sleep, then wakes it up on the next cycle after the lock is freed.
Hangs have varied causes and symptoms, including software or hardware defects, such as an infinite loop or long-running uninterruptible computation, resource exhaustion , under-performing hardware , external events such as a slow computer network, misconfiguration, and compatibility problems. The fundamental reason is typically resource ...

The simplest type of lock is a binary ...
