Computer system including a plurality of nodes for transferring through a data transfer network messages having distinguishing fields used for distinguishing the messages and controlling receipt thereof

摘要

A computer system having a plurality of processing nodes interconnected by a message transfer network. Each node includes an instruction processor, a transmit circuit to transmit messages to other processing nodes through the message transfer network and a plurality of postings in a memory storage. Each message includes a header part and a data part with the header part having distinguishing fields that are used to distinguish messages. Each posting includes message specification fields corresponding to each distinguishing field of a message header part wherein the message specification fields selectively matching the distinguishing fields of a message. Each posting further includes a posted control field wherein the posted control field is used to control the operation of a receive circuit with respect to a message matching the posting. The receive circuit enables receiving of messages sent by other processing nodes through the network, searching upon reception of each message for and locating a posting having message specification fields that match the corresponding distinguishing fields of the message being received and to control upon location of a posting, the posted control field to control the operation of the receive circuit with respect to the message being received.
