+ * The coord parameter depends on the cluster being created:
+ * - Torus: Direct translation of the Torus' dimensions, e.g. (0, 0, 0) for a 3-D Torus
+ * - Fat-Tree: A pair (level in the tree, id), e.g. (0, 0) for first leaf in the tree and (1,0) for the first switch at
+ * level 1.
+ * - Dragonfly: a tuple (group, chassis, blades/routers, nodes), e.g. (0, 0, 0, 0) for first node in the cluster. To
+ * identify the router inside a (group, chassis, blade), we use MAX_UINT in the last parameter (e.g. 0, 0, 0,
+ * 4294967295).
