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.
