-- Example 1
   


-- cette fonction met en place l'architecture d'exécution de l'environnement
-- elle permet de construire le Noc et de connecter les différents core MPI
-- chaque core reçoit un ID qui sera son Rank lors de l'appel à MPI_GET_Rank
-- faut il créer une petite mémoire chargée de stocker les IDs ?
-- Oui car cette mémoire sera consultée par la fonction MPI_Init pour associer
-- un communicateur au MPI Core
