EDIT: As identified accurately by Bo Persson, the duplicate operation done through the wrapper is not really atomic. It allows you to copy atomic objects, but the duplicate by itself is not atomic.
Loop until eventually you realize success as well as your will be the thread which owns the lock. Unlock by setting the current Edition selection Along with the lock-bit cleared. The paper describes using the version figures within the locks to coordinate that threads Have a very consistent set of reads whenever they compose.
So in order to employ the above mentioned three Directions in an atomic manner, we should always initial get exclusive use of the cacheline which has the essential price. When we get unique obtain, we must not relinquish exceptional access on this cacheline until eventually the "shop" operation is accomplished.

When two threads function concurrently on a shared variable and one of those steps entails crafting, both equally threads have to use atomic functions.
