Designing massively parallel algorithms with Parallaxis

Parallaxis is a programming language for massively parallel single instruction-multiple data (SIMD) systems, based on Modula-2. There are only a small number of additional constructs to handle parallel data (vectors) and data exchange among processors or between the front-end and back-end. Parallaxis helps to solve parallel problems in a natural way and does not require special skills. The major language constructs are described and a number of sample programs are given together with their simulated processor element PE-load and efficiency values. Parallaxis is available as a simulation system which is chiefly used in universities for instructional purposes. However, a compiler for the massively parallel MasPar computer system has been finished, and a compiler for the Connection Machine is being developed
