| Abstract: | The parallel logic language Shared Prolog embeds Prolog as its sequential component.

The model of communication puts Shared Prolog in the Linda family of parallel languages. The current prototype implementation is exposed. The architecture of the system is a distributed network of extended Prolog interpreters running under Unix and communicating via Internet sockets, and was obtained refining a specification written in SP itself. |
