Abstract: In this work, two parallel implementation strategies for the numerical simulation of wind flow around buildings were developed based on a four-processor transputer system. The first parallel strategy is based on the functional decomposition of the problem. It is easily implementable, but the degree of parallelism is low. In the second strategy, both the functional and the domain parallelisms of the problem were utilized, so the degree of parallelism is highly increased. Numerical examples indicate that the parallel speed-ups and efficiencies achievable by the second strategy are significantly greater than those of the first one.
