Abstract :
A methodology for the derivation of parallel implementations from program specifications is developed. The goal of the methodology is to decompose a program specification into a collection of module specifications via property refinement, such that each module may be implemented independently by a subprogram. The correctness of the implementation is then deduced from the correctness of the property refinement procedure and the correctness of the individual subprograms. The refinement strategy is based on identifying frequently occurring control structures such as sequential composition and iteration. The methodology is developed in the context of the UNITY logic and the UC programming language, and illustrated through the solution of diffusion aggregation in fluid flow simulations
