DESIGN OF AN OBJECT BASED MULTIPROCESSOR SYSTEM

This paper gives an outlook of the design of a parallel object-based system, with special considerations on the communication aspects, regarding both computational model and implementation architectuure. The system primitives are designed to be sufficiently general to allow experiments with several kinds of object based languages. Concerning objects granularity, our purpose is to start experimenting with relatively small objects (medium-sized C programs), and then gradually improve the architecture design for giving support to finer grain objects. From the architecture standpoint, our targets are tightly-coupled multiprocessors. As detailed in SECTION 4, we have given special support for synchronization between objects, introducing a special hardware for managing a global object table .
