Abstract
The numerical simulation of a 2- or 3-dimensional motion of viscous multiphase flow can be described by a system of partial differential equations. Because this simulation poses extremely high demands on computing capacity it is very well suited for calculation by a multiprocessor. This paper describes the implementation of FLUBOX, a two-dimensional fluid dynamics code developed at the Gesellschaft für Reaktorsicherheit on an iPSC/2 distributed memory multiprocessor. The main criterion for evaluation was to get a good speedup by changing only small parts of the program. The program has been analyzed using the performance analyzer PATOP developed in the TOPSYS project. In this way, we were able to study the dynamic behaviour of the algorithm.
