In this research, we studied programming language, programming environment, and object oriented parallel architecture for knowledge engineering. Our originality consistsd 6 parts as follow.1. Parallel object oriented language based on single assignment.2. Programming environment using database of names in programs.3. Corespondence of types and names in programs.4. Object oriented parallel architecture based on context granularity, which is based on message passings for an argument transfer.5. Parallel program debugging using Petri-net model.6. Browsing tools for inspecting global relationship among objects.We introduced non-determinism for the object oriented language by a messsage randevouz mechanism called "join". This language has enough expressive power for many kinds of parallel programs. Through the simulation of the parallel architecture, we convinced the mechanism of context-driven execution model and object oriented load-distribution mechanism works well. The prototype of programming environment was built and tested.
