SDCS: Simplified Data Communications in Parallel/Distributed Applications

This paper presents SDCS (Simple Data Communication and Sharing), a programming model for data communications in parallel/distributed applications. With SDCS, developers can define data communications in shared memory style and have the model translate the declarations into corresponding message passing code. The translation from data sharing declarations to message passing code is based on simple mapping rules to lower runtime overhead and increase understandability of the model. Some frequently seen data communication modes are well supported to enhance its usability. SDCS can effectively reduce the difficulty in programming process communications.
