Abstract: The development of high performance simulation application works on the premise that the appropriate compuling platform is selected, and the parallel optimization direction of program is determined. Therefore, this paper researched on the applicability between the parallel computing platform and high performance simulation program Especially, three character sets arc distilled, including the performance character set of simulation program, the performance indicator system of parallel computing platform, and the element set of parallel optimization targets, so as to theoretically guide the methods of platform selection and program optimization more completely. Moreover, based on these three researches, this paper proposes the methods of determining the program applicability and platform applicability. The cases study indicates that the research achievement in this paper can guide the selection of the appropriate computing platform,and guide the development of performanc}oriented parallel optimization techniques.

Key words: Parallel computing platform, Simulation program, Performance character, Platform selection, Program optimization
