Data driven C--A concurrent programming language

Abstract

Data driven C (DDC) is a new concurrent programming language designed for machines with message passing architecture. The concurrent programming extensions to C are based on the single rendezvous concept. The authors discuss the creation of a process, interaction between processes and the integrated module in DDC. A process is the most basic computation unit in a DDC program. A process with large grain size tends to incur less communication cost. Hence, DDC encourages programmers to create large grain process by requiring each process to be declared separately with a process header. DDC integrates component processes into a reusable integrated module. The main contribution of DDC is its introduction of socket as a flexible channel naming scheme and a concurrent code packaging technique called the integrated module.
