Abstract: Embodiments of the present invention provide a data synchronization method and apparatus. The method includes: scanning a code to capture a synchronization instruction; replacing the captured synchronization instruction with a trap instruction; and when the code runs to the trap instruction, trapping a code execution right into a distributed shared memory (DSM) unit, where the DSM unit implements a concurrent multi-write protocol, but implements a single-write protocol when executing the synchronization instruction, thereby supporting the concurrent multi-write protocol and solving the synchronization problem caused by the concurrent multi-write protocol.
Abstract translation: 本发明的实施例提供了一种数据同步方法和装置。 该方法包括：扫描代码以捕获同步指令; 用陷阱指令代替捕获的同步指令; 并且当代码运行到陷阱指令时，将代码执行权陷入到分布式共享存储器（DSM）单元中，其中DSM单元实现并发多写协议，但是当执行同步指令时实现单写协议， 从而支持并发多写协议并解决由并发多写协议引起的同步问题。
