SISCAD-P -- 2.0.0 -- 01/Aug/95 (demo only, which is limited to the drawing of a maximum of 5 parts of 300 objects each).

SISCAD-P is a new innovative 2D-CAD system that gives engineers a production implementation of new design technologies - parametrics, variational geometry, inference sketching, a fully customizable user interface, constraint-based modeling and feature-based modeling. SISCAD-P dramatically reduces the product design cycle times. Parametric design captures design intent and allows you to build dimension- driven geometry with geometric constraints such as tangency, parallelism and colinearity. Intelligent menus and processes enable you to perform operations with the smallest possible number of "working" steps with little or even no keyboard entries. Constraint-based modeling allows you to perform "what-if" analysis to get the best design solutions. Feature-based modeling allows you to include standard design elements in your model and eliminates traditional, time-consuming modeling operations. All these new techniques are the result of a relational, object-oriented data structure as a basic concept of SISCAD--P.

Mentat is an object-oriented parallel processing system designed to directly address the difficulty of developing architecture-independent parallel programs. The fundamental objectives of Mentat are to (1) provide easy-to-use parallelism, (2) achieve high performance via parallel execution, and (3) facilitate the execution of applications across a wide range of platforms. The Mentat approach exploits the object-oriented paradigm to provide high-level abstractions that mask the complex aspects of parallel programming, including communication, synchronization, and scheduling, from the programmer. Instead of managing these details, the programmer concentrates on the application. The programmer uses application domain knowledge to specify those object classes that are of sufficient computational complexity to warrant parallel execution. WWW
