Abstract: The availibility of low cost microprocessors, memories and ancilliary circuits has made the construction of large networks of such devices feasible where each microcomputer is dedicated to a specific task. The parallel computation of the diffusion equation is a particular application of such a multi-microcomputer network where each microcomputer simulates a given region and exchanges partial results with its neighbours. Structure of a network where each node consists of a microcomputer linked to other nodes by means of serial communication lines is described. The explicit finite difference algorithm is adapted for an 8-bit architecture most commonly available today. The algorithm is emulated on a minicomputer and the results presented. Availibility of processing power and memory at each node is significant for the simulation of non-linear problems which has been discussed. The significance of full parallelism where a microcomputer is allocated to each problem node and partial parallelism where a microcomputer simulates a number of nodes which form a region is covered.
