Message-passing multiprocessor system

Abstract

A message-passing multiprocessor system, such as, a network interface, a method for transferring messages between a node and a node, and a method for formatting the same in a message-passing computer system are disclosed herein. In the network interface for a computer system there are a plurality of nodes connected with one another through an interconnection network for communicating messages, and more than one processor, and a local shared memory, which are connected with one another through a node bus. These components are connected via the network interface to the interconnection network, the multiprocessor comprises a local bus acting as a path for transferring data in the network interface, a bus connection for connecting the node bus and the local bus, a transferring component for packetizing the messages requested by the processor, if data message, by reading them out from the local shared memory via the local bus, the bus connection and the node bus to produce a packet, and sending the packet to the interconnection network, and a receiver for receiving the message packet from the interconnection network, restoring it to produce a restored message and, if data portion of the data message, storing the restored packet body into the local shared memory through the local bus, the bus connection and the node bus.
