Abstract

After a brief outline of the basic concepts of laser fusion, the implementation of the 2-D laser fusion fluid code DUED on the IBM 3090 VF vector multiprocessors is discussed. Emphasis is put on parallelization, performed by means of IBM Parallel FORTRAN (PF). It is shown how different modules have been optimized by using different features of PF, including modules based on depth-2 nested loops which exploit automatic parallelization. Laser light ray tracing is partitioned by scheduling parallel tasks and 9-diagonal sparse linear systems are solved by a parallel ICCG algorithm (executed in parallel by appropriately synchronized parallel subroutines). Performance results are given for separate modules of the code, as well as for typical complete runs.
