Refinement from Z Specification to Parallel Program
一种从Z规约到并行程序的精化方法

In this paper, a method of getting parallel program from Z specification through refinement of design patterns is proposed. It expands parallel concepts into Z notation. Beginning with Z functional specification, it refines expanded design patterns step by step to get parallel design, and succeed in obtaining abstract parallel program through semantic-preserving transformations, which can be transformed to parallel code finally. This method is described in detail through an example.
