This paper researches on parellelization of multiphase space numerical simulation with the case of the gaskinetic algorithm for 3-D flows. It focuses on the techniques of domain decomposition methods, vector reduction andboundary processing parallel optimization. The HPF parallel program design has been developed by the Parallel Pro-gramming Concept Design (PPCDS). The preferable parallel efficiency has been found by the HPF program in highperformance computer with massive scale parallel computing.
DPHL is a Data Parallel High-level modeling Language,with which users can describe prob-lem-solving course in algorithmic level,closer to their perspectives. Domain is a basilic concept intro-duced in DPHL. This paper discusses the definition of domain and its Abstraction method in supporting parallel program conceptual design.
