A Real-Time and Distributed System with Programming Language Abstraction

As processing and time requirements of computer systems increase over borders of single processor architectures, it is becoming more and more attractive to use distributed computing with additional real-time capabilities. In several cases, traditional programming languages have become insufficient to build distributed systems easily, especially when real-time issues and basic software quality factors such as reliability, correctness, robustness, ease of design, development, testing and maintenance are concerned. In this paper basic issues relevant to distributed systems are reviewed, a concurrent, object-oriented, real-time and distributed programming language, CORD-PL, with its supportive run-time system is introduced and its features are described. The new system provides an efficient solution for especially command and control systems by embedding distribution and real-time issues within the programming language structures.
