  abstract = {One of the foundations of any HPC cluster is the network topology. The choice of topology is dictated by properties such as cost, network technology, and target applications. For InfiniBand (IB) the Fat-tree is the dominating topology, but recently we have also seen IB clusters based on a 3d Torus. From time to time new topologies are invented and in this talk we will have a closer look at the recently proposed Dragon-fly topology and compare it with the well established Fat-tree topology.},
