Parlog

Parlog is a logic programming language designed for efficient utilization of parallel computer architectures. Its semantics is based on first order predicate logic. It expresses concurrency, interprocess communication, indeterminacy and synchronization within the declarative language framework.Andrew Cheese, "Parallel execution of Parlog", Springer, 1992, {{ISBN|3-540-55382-7}}, 184 pp.

It was designed at Imperial College, London by Steve Gregory and Keith L. Clark, as a descendant of IC Prolog and Relational Language."Programming distributed systems", by H. E.
