Jens Gustedt. Data Handover: Reconciling Message Passing and Shared Memory. In Foundations of Global Computing. Dagstuhl Seminar Proceedings, Volume 5081, pp. 1-13, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2006)


Data Handover (DHO) is a programming paradigm and interface that aims to handle data between parallel or distributed processes that mixes aspects of message passing and shared memory. It is designed to overcome the potential problems in terms of efficiency of both: (1) memory blowup and forced copies for message passing and (2) data consistency and latency problems for shared memory. Our approach attempts to be simple and easy to understand. It contents itself with just a handful of functions to cover the main aspects of coarse grained inter-operation upon data.
