Abstract: An apparatus and method of accessing data in a memory in a multi-node, high performance computing system has a requesting agent and a home agent. The requesting agent is a member of a first node of the high performance computing system, while the home agent is a member of a second node of the high performance computing system. The home agent forwards data in a specified memory toward the requesting agent across the unordered network, and determines that a snoop request is to be sent to the requesting agent. After determining that the requesting agent has received the requested data in the specified memory of the second node, the home agent forwards the snoop request to the requesting agent across the unordered network.
