Pour etre bien certain que le code est safe, on force une communication synchrone pour forcer le blocage en mode check (voir check_enabled() ). Sinon, on utilise MPI_Send qui est en general non blocant pour les petits messages (donc de meilleures performances).

send_recv_start

void Comm_Group_MPI::send_recv_start(const ArrOfInt &send_list, const ArrOfInt &send_size, const char *const *const send_buffers, const ArrOfInt &recv_list, const ArrOfInt &recv_size, char *const *const recv_buffers, TypeHint typehint=CHAR) const override

Demarre l’envoi et la reception des buffers.

Les buffers doivent rester valide jusqu’au retour de send_recv_finish() . Le graphe de communication et la taille des buffers doivent etre corrects ! send_list : liste des processeurs (numerotation sur groupe courant) a qui envoyer send_size : taille en octets de chaque message send_buffers : adresse des donnees a envoyer. recv_… : idem pour les donnees en reception.
