Quintus Computer Systems Inc, Mountain View, California, and Sequent Computer Systems Inc, Beaverton, Oregon, jointly announced that the Quintus Prolog Multiprocessing Package was available for parallel computers. The knowledge engineering product is designed exclusively for parallel processing systems. The partners reckon that Prolog on Symmetry will benefit a range of knowledge-based applications such as economic modelling, diagnostics, expert systems, configurators, simulation, data manipulation, transaction and numerical processing, computer aided engineering and computer-aided software engineering. Quintus enlisted the aid of two of Sequent’s major university and research customer sites, the Argonne National Laboratory and the University of Edinburgh, Scotland for development and testing of the new knowledge-based system. No price or delivery details of the new package were given.
