Abstract

This document describes the work on Message Passing Interface (MPI) standard implementation of the parallel version of the solver EARTH for the Computational Fluid Dynamics (CFD) program PHOENICS. The Intel Paragon NX and MPI versions of the program have been developed and tested on massively parallel (MP) supercomputers Intel Paragon XP/S 5, XP/S 35, and Kendall Square Research (KSR) supercomputers at Oak Ridge National Laboratory (ORNL). The preliminary testing results of the developed program have shown scalable performance for reasonably sized computational domains.
