Abstract;It has been difficult to carry out multi-dimensional radiative transfer calculations, because they demand huge amount of calculations. But the difficulty can be overcome by using large computers, though calculation sequences have to be considered carefully Under the calculation sequence restriction, we have invented a method which enables us to use a massively parallel processor efficiently. A wave front of PUs on which radiative intensities with same direction and frequency are calculated concurrently is formed in a PU-space. And multiple wave fronts with different directions or frequencies cover the entire PU-space. We have implemented the method onto a massively parallel processors, the CP-PACS, and confirmed the method attained high parallelization efficiency. (author abst.)
