Sequential consistency (SC)模型是最直观的memory model,它是程序员对共享内存的预期行为,并为理解其它memory model提供了基础。在SC模型中,memory order保留了每个core的program order。也就是SC模型为同一个线程的两个指令间的所有四种load和store组合(Load -> Load, Load -> Store, Store -> Store, and Store...

不要求PE外的memory system能够识别通过multi-register load/store instructions来访问的元素。 见B2.15.1.4 Multi-register loads and stores that access Normal memory. 当load或store指令执行了一系列的memory访问,而不是由single-copy atomicity规则定义的一个single-copy atomic访问时,执行load或store指令的导致的这...

如果buffer 未满,则 store 进入 FIFO write buffer 的尾部;如果 buffer 已满,则 store stall 核心。 当switch 选择核心 Ci 时,它要么执行下一次 load,要么执行 write buffer 头部的 store。 在第3.7 节中,我们展示了对于 SC,交换机可以被缓存 coherent 内存系统替换,然后认为核心可以是推测性的和/或多线程的...

Techniques related to an in-memory key-value store for a multi-model database are disclosed. In an embodiment, a relational database may be maintained on persistent storage. The relational database may be managed by a database server and may include a database table. The database table may...
x86 Total Store Order (x86-TSO) The memory model for modern x86 systems corresponds to this hardware diagram: All the processors are still connected to a single shared memory, but each processor queues writes to that memory in a local write queue. The processor continues executing new instructi...
