Design of a simulation interface for a parallel computing environment

A user interface for simulation of contaminant transport in groundwater flow using a distributed memory parallel processor is described. The user interface is a menu-mouse driven presentation using the X-Windows software. To facilitate the division and distribution of data among processors and to develop a data structure capable of manipulation for a variety of functions, graphics, remeshing, input and retrieval of auxiliary information, an object oriented programming style is used. The parallel computational model for the update of contaminant concentrations is organized around objects and an explicit time marching algorithm implemented on an IPSC2 Hypercube multiprocessor. 6 refs.
