Last change on this file since 1489 was 1001, checked in by Laurent Fairhead, 16 years ago
  • Modifs sur le parallelisme: masquage dans la physique
  • Inclusion strato
  • mise en coherence etat0
  • le mode offline fonctionne maintenant en parallele,
  • les fichiers de la dynamiques sont correctement sortis et peuvent etre reconstruit avec rebuild
  • la version parallele de la dynamique peut s'executer sans MPI (sur 1 proc)
  • L'OPENMP fonctionne maintenant sans la parallelisation MPI.
