High-level message-passing constructs for Zipcode 1.0: design and implementation

Zipcode is a message passing system that was initially designed for multicomputers and homogeneous networks of computers. The paper describes Zipcode "invoices," which raise the message-passing interface of Zipcode to a higher level of abstraction. The "gather-send" and "receive-scatter" semantics enable heterogeneous communication. The higher level of abstraction also simplifies message passing and reveals more optimizations. We explain the utility of these features and give examples of the calling sequences that implement them. All of these features are seen as enablers for parallel library development and large applications.<
