On distribution of coordinated atomic actions

The concept of coordinated atomic (CA) actions was introduced about two years ago. Since then this research has addressed many new problems and, in particular, problems of CA action distribution and implementation. Recently we have gained some experience in implementing different schemes in Ada 95 and Java. Our intention within this paper is to discuss how distributed CA action schemes can be realised. In particular, we outline different ways of action component distribution, trade-offs, applications for which these schemes are applicable. We discuss a wide range of schemes (some of them have not yet been implemented) based on a classification of various approaches to CA action distribution; to do this we analyse all possible ways of different action component distribution. We believe that this general discussion should help to better understand the current state of CA action implementation and is important for future research in CA actions.
