Abstract
Each node's memory controller may be configured to send and receive messages on a dedicated memory-to-memory interconnect according to the communication protocol and to responsively perform memory accesses in a local memory. The type of message sent on the interconnect may depend on which memory region is targeted by a memory access request local to the sending node. If certain regions are targeted locally, a memory controller may delay performance of a local memory access until the memory access has been performed remotely. Remote nodes may confirm performance of the remote memory accesses via the memory-to-memory interconnect.
