As a case study in the parallelization of complex codes for physical research, the implementation of a 2-D laser fusion code on an IBM 3090-VF vector multiprocessor by means of IBM parallel FORTRAN is described. The relationship between physical models, algorithms and optimization techniques is evidenced with particular reference to finite difference schemes, sparse linear system solvers and ray-tracing methods. A parallel ICCG solver has also been implemented and tested. Performances of the parallel code are reported for typical physically significant problems.
