A computational procedure has been developed for simulating 2D and 3D incompressible steady state flows in enclosed spaces with parallel processing based on an HX network computing system. The numerical procedure is based on a modified SIMPLE algorithm and has been parallelized with matrix calculation. Performance of the parallel computation has been examined through simulating laminar flows in enclosed spaces. In the case of computation with 256 processors, inter-processor communication time occupies about 10% of total calculation (CPU executing) time. When the data structure (i. e. dimension and size of data matrix) of the numerical procedure matches the characteristics of the computer system, the speedup ratio of parallel computation is proportional to the number of processors.
