Abstract
In a previous work we studied the concurrent implementation of a numerical model, CONDIFP, developed for the analysis of depth-averaged convection–diffusion problems. Initial experiments were conducted on the Intel Touchstone Delta System, using up to 512 processors and different problem sizes. As for other computation-intensive applications, the results demonstrated an asymptotic trend to unity efficiency when the computational load dominates the communication load. This paper relates some other numerical experiences, in both one and two space dimensions with various choices of initial and boundary conditions, carried out on the Intel Paragon XP/S Model L38 with the aim to illustrate the parallel solver versatility and reliability.
