/* In a decomposition graph each node represent a sub-domain while an edge represent
 * an interaction between sub-domain (it mean that they have to communicate).
 *
 * Here we list the of property that a vertex node can carry with a brief
 * explanation:
 *
 * x = position x of the sub-domain
 * y = position y of the sub-domain
 * z = position z of the sub-domain
 * communication = is the estimated total communication produced by the sub-domain
 * computation = the total computation produced by the sub-domain
 * memory = estimated memory required by the sub-domain
 * id = which processor own this sub-domain
 * sub-id = sub-decomposition where each group of sub-domain is organized in an
 *          hyper-cube
 *
 * Here we list the properties that an edge node can carry with a brief explanation
 *
 * communication = is the estimated communication between sub-domains
