-# Quick script to generate hierarchical clusters. Usage : <the script> p s d where :
-# - p : 2^p gives the total number of hosts.
-# - s : cluster size
-# - d : degree of inner nodes.
-#
-# output is the standard one.
-#
-#
-#Each node is numbered by a DFS in the tree. Each cluster is numbered by the DFS number of the leaf it is attached to and the number of cluster for each leaf.
-# Other infos :
-# - Same bb_lat used for any routers inside (not that complicated to modify too).
-# - constants defined in the first part of the script corresponding to classic cluster parameters. links_bw and links_lat added for the inner tree links
-# - bb_lat and bb_bw used in any backbone of the tree.
-# - fails if you set an obviously too small total number of hosts compared to the cluster size (generates a lot of stuff for nothing actually).
