ABSTRACT:
A method and apparatus for reducing the software overhead of message passing in parallel systems. Special purpose hardware assists in constructing each data message sent through a network. Message passing systems generally require that every message be prefixed with a message header describing the key control parameters of the message. The software task is to construct the message header for every message individually and to transmit the header prefixed to every message. The software is relieved of constructing the message header and uses special purpose hardware to accomplish the job more efficiently.
