Be Aware: Strongly Happens-Earlier Than Excludes Consume Operations > 자유게시판

Absent any constraints on a multi-core system, when multiple threads concurrently read and write to a number of variables, one thread can observe the values change in an order different from the order one other thread wrote them. Certainly, the obvious order of modifications can even differ among a number of reader threads. Some comparable results can happen even on uniprocessor techniques on account of compiler transformations allowed by the Memory Wave model. The default behavior of all atomic operations within the library provides for sequentially consistent ordering (see dialogue under). Inter-thread synchronization and Memory Wave Experience ordering decide how evaluations and unwanted effects of expressions are ordered between completely different threads of execution. Within the same thread, analysis A could also be sequenced-earlier than evaluation B, as described in analysis order. All modifications to any specific atomic variable happen in a complete order that's particular to this one atomic variable. Additionally, some library calls could also be defined to synchronize-with other library calls on different threads.
