Trends in esign for Distributed Computing Systems

Due to the rapid development of VLSI technology, computing systems can be made much more distributed and to match the structures of the problems for various applications. Because the characteristics of distributed computing systems are significantly different from those of centralized computing systems, different a,pproaches are needed to effectively address t,he design issues related to the characteristics of software for distributed computing systems. In this pa.per, the methods currently used to develop the software for distributed computing systems are classified into three categories: dataflow-oriented, communicationoriented, and object-oriented. Their applicabilities are conpa.red, and the future trends of software design approaches are discussed. Object-oriented software design methodoiogy is identified as a more promising approach to software design for distributed computing systems.
