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.
