US Patent 7913048 Data subscribe-and-publish mechanisms and methods for producer-consumer pre-fetch communications

A system supporting producer-consumer pre-fetch communications includes a first processor, wherein the first processor is a producer node, and a second processor, wherein the second processor is a consumer node. The system further includes a data subscribe mechanism for performing a data subscribe operation at the consumer node, wherein the data subscribe operation records that a memory address is subscribed at the consumer node, a data publish mechanism for performing a data publish operation at the producer node, wherein the data publish operation sends data of the memory address from the producer node to the consumer node if the memory address is subscribed at the consumer node, and a communication network coupled to the producer node and the consumer node for enabling communicating between the producer node and the consumer node.
