Abstract : Here we report on development of a high order finite element code for the solution of the shallow water equations on the massively parallel computer MP-1104. We have compared the parallel code to the one available on the Amdahl serial computer. It is suggested that one uses a low order finite element to reap the benefit of the massive number of processors available.... Finite element approximation, Shallow water equations.
