    Abstract: An apparatus for providing data coherency is described herein. The apparatus includes a global persistent memory. The global persistent memory is accessed using a protocol that includes input/output (I/O) semantics and memory semantics. The apparatus also includes a reflected memory region. The reflected memory region is a portion of the global persistent memory, and each node of a plurality of nodes maps the reflected memory region into a space that is not cacheable. Further, the apparatus includes a semaphore memory. The semaphore memory provides a hardware assist for enforced data coherency.

    Abstract translation: 这里描述了一种用于提供数据一致性的装置。 该装置包括全局持久存储器。 使用包含输入/输出(I / O)语义和内存语义的协议来访问全局永久存储器。 该装置还包括反射存储区域。 反射的存储器区域是全局持久存储器的一部分,并且多个节点的每个节点将反射的存储器区域映射到不可高速缓存的空间中。 此外,该装置包括信号量存储器。 信号量存储器为强制数据一致性提供硬件辅助。
