Abstract
A message passing parallel processing system capable of executing different types of intercommunication protocols simultaneously, as well as plural instances of each type of protocol. Each processing node of the system contains a message passing protocol apparatus comprising a protocol processor and a memory. Messages passed between nodes contains, inter alia, a protocol type and an identification of an instance of the protocol type. Examples of protocol types might be shared memory, hierarchical tree connect, distributed sets, etc. Messages are passed to processing nodes from other processing nodes in fixed sized blocks and only when input buffers are empty. Flow control of the network is self-regulating and the network is deadlock free.
