Parallel Solutions of Three-Dimensional Compressible Flows

摘要: In this report, we present parallel solutions of realistic three-dimensional flows obtained on the {\tt Intel Paragon}, Cray T3D} and Ibm SP2} MPPs (Massively Parallel Processors). The solver under consideration is a representative subset an existing industrial code, N3S-MUSCL} (a compressible Navier-Stokes solver, see Chargy\cite{Cha1}). It implements mixed finite element/finite volume formulation unstructured tetrahedral meshes. Defining good strategy for parallelisation mesh based challenge, particularly when one aims at reaching high level performance while maintaining portability source code between scalar, vector machines. adopted in study combines partitioning techniques message-passing programming model. algorithms generation corresponding communication data-structures are gathered preprocessor order to introduce minimum change original serial code. from message passing system another may be enhanced with use library such as PVM}.
