25 * NOTE:
26 * Le but est est IParallelNonBlockingCollective possède les
27 * mêmes méthodes collectives que IParallelMng. Cependant, certaines
28 * méthodes collectives de IParallleMng font en fait appel dans leur
29 * implémentation à plusieurs appels collectifs. Il n'est donc pas
30 * possible de transformer cela directement en opérations collectives.
31 * Pour implémenter cela avec MPI, il faudrait pouvoir associer un callback
32 * à chaque requête (ce callback serait appelé lorsque la requête est terminée)
33 * qui permettrait de poursuivre les opérations. Mais cela
34 * n'est pas disponible actuellement (peut-être cela est-il possible
35 * avec les requêtes généralisées).
36 * En attendant, on supprime de l'interface ces appels en les protégeant
37 * par un define _NEED_ADVANCED_NBC.
