Abstract
A preferred embodiment of the present invention includes a method and apparatus for sending messages between memory spaces included in a computer network. More specifically, for a preferred embodiment, each memory space included in a computer network is identified by a site id that is composed of a manufacturer id and a machine id. When messages are sent between memory spaces, the site id of the sending memory space is compared to the site id of the receiving memory space. If the site ids match, the message is sent using an intra-memory copy. Otherwise a networking protocol is invoked. Importantly, the comparison between site ids occurs relatively early in the sending of the message. As a result, efficiency is increased in cases where a message is being sent within the same memory space.
