Arche: a framework for parallel object-oriented programming above a distributed architecture

This paper sketches our experience with the design and implementation of a parallel object-oriented language and it distributed run-time system. The language integrates two original mechanisms for concurrency control: a synchronization mechanism that does not interfere with inheritance nor with subtyping, and a mechanism that serves for managing object groups. Because of the increasing power of interconnection networks, the language´s run-time system has been designed for a distributed architecture instead of a single multiprocessor machine. Furthermore, in order to ease the development of correct applications, we have chosen to rely on the run-time system to provide the required efficiency instead of offering the programmer low level primitives to be used for producing efficient code
