This paper presents a new parallel strategy for radiative transfer calculation coupled with hypersonic flow computations. The cell-interface division parallel strategy is developed based on the distributed-memory parallelization, and applied to the calculation of threedimensional radiative transfer in axisymetric hypersonic flowfieM around the forebody of Fire II vehicle. The developed parallel code realizes fair scalability up to 128 processors. The computational speed achieved by the present parallel strategy using 128 processors of SGI ORIGIN 2000 is approximately 20 Gflops that is 115 times faster than that of a single processor. It is shown that cell-interface division strategy is suitable for large-scale radiation coupling calculations.
