Abstract
A messaging facility in a multiprocessor computer system includes assembly circuitry in a source processing element for assembling a message to be sent from the source processing element to a destination processing element based on information provided from a processor in the source processing element. A network router transmits the assembled message from the source processing element to the destination processing element via an interconnect network. A message queue in a local memory of the destination processing element stores the transmitted message. A control word stored in the local memory of the destination processing element includes a limit field designating a size of the message queue and a tail field designating an index into the corresponding message queue to indicate a location in the message queue where the transmitted message is to be stored. Shell circuitry in the destination processing element atomically reads and updates the tail field.
