Large scale massively parallel computations with the block-structured elsA CFD software

Part of the Lecture Notes in Computational Science and Engineering book series (LNCSE,volume 74)

Abstract

We describe work performed inside the elsA (http://elsa.onera.fr) block-structured CFD software to analyse and improve parallel computation efficiency. Details of MPI implementation are discussed. Computational results are given for realistic industrial configurations (28 106 mesh points) on several massively parallel platforms up to 1024 processors.

Keywords

  • Computational Fluid Dynamics
  • Load Balance
  • Communication Graph
  • Independent Edge
  • Parallel Speedup

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
