-/**
- * \class AsClusterDragonfly
- *
- * \brief Dragonfly representation and routing.
- *
- * Generate dragonfly according to the topology asked for, according to:
- * Cray Cascade: a Scalable HPC System based on a Dragonfly Network
- * Greg Faanes, Abdulla Bataineh, Duncan Roweth, Tom Court, Edwin Froese,
- * Bob Alverson, Tim Johnson, Joe Kopnick, Mike Higgins and James Reinhard
- * Cray Inc, Chippewa Falls, Wisconsin, USA
- * or http://www.cray.com/sites/default/files/resources/CrayXCNetwork.pdf
- *
- * We use the same denomination for the different levels, with a Green,
- * Black and Blue color scheme for the three different levels.
- *
- * Description of the topology has to be given with a string of type :
- * "3,4;4,3;5,1;2"
- *
- * Last part : "2" : 2 nodes per blade
- * Third part : "5,1" : five blades/routers per chassis, with one link between each (green network)
- * Second part : "4,3" = four chassis per group, with three links between each nth router of each chassis (black network)
- * First part : "3,4" = three electrical groups, linked in an alltoall
- * pattern by 4 links each (blue network)
- *
- * LIMITATIONS (for now):
- * - Routing is only static and uses minimal routes.
- * - When n links are used between two routers/groups, we consider only one link with n times the bandwidth (needs to be validated on a real system)
- * - All links have the same characteristics for now
- * - Blue links are all attached to routers in the chassis n°0. This limits
- * the number of groups possible to the number of blades in a chassis. This
- * is also not realistic, as blue level can use more links than a single
- * Aries can handle, thus it should use several routers.
