Absent any constraints on a multi-core system, when multiple threads simultaneously read and write to several 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 changes may even differ among multiple reader threads. Some similar effects can occur even on uniprocessor techniques resulting from compiler transformations allowed by the memory mannequin. The default conduct of all atomic operations in the library provides for sequentially constant ordering (see dialogue under). Inter-thread synchronization and Memory Wave Routine ordering determine how evaluations and side effects of expressions are ordered between different threads of execution. Within the identical thread, evaluation A could also be sequenced-earlier than analysis B, as described in evaluation order. All modifications to any specific atomic variable happen in a complete order that's particular to this one atomic variable. Also, some library calls could also be defined to synchronize-with different library calls on different threads.
