Distributed and parallel execution in Ada 83

Since the standardization of the Ada programming language in 1989, much research has gone into the distribution of Ada programs across a number of separate processors. However, no standard for distribution of Ada 89 programs has emerged. A new language standard, known as Ada 95, includes explicit support for the distribution of Ada programs. This paper describes the techniques and a graphical tool which allow the distribution of Ada 85 programs, using a sub-set of the methodology developed for Ada 95, with extensions to allow coarse grain parallel programming. This work is also a precursor to an implementation of the Ada 95 Distributed Systems Annex being developed by the authors in cooperation with the NYU GNAT team and France Telecom University.<>
