- Data Center Network Topologies: FatTree
Clos Networks Fat-Trees Adopt a special instance of a Clos topology Similar trends in telephone switches led to designing a topology with high bandwidth by interconnecting smaller commodity switches
- Networks for High-Performance Computing - GitHub Pages
Three different network topolo-gies, the Fat Tree, Torus, and Dragonfly have been surmised in brief, as well as some information and commonly used methods for providing reliability and details as to why topology determines the fault tolerance of a network
- Dragonfly+: Low Cost Topology for Scaling Datacenters
Network topology impacts the application performance Common topologies: Fat Tree, Dragonfly, Hyper-cube, Torus, SlimFly Keys to topology evaluation: Network throughput - for various traffic patterns Network diameter – min average max latency between end-hosts
- Energy efficient HPC network topologies with on off links
We conduct experiments on three widely used network topologies, namely torus, fat-tree and Dragonfly, applying low-power modes based on the Energy Efficient Ethernet standard
- HPC-Opinion: Cluster Topologies - Dragonfly
Simply saying, a dragonfly topology is a two level (at least) topology where at the top level groups of switches are connected in a full graph The internal structure of the groups may vary and be constructed as full graph, fat tree, torus, mesh, dragonfly and so on
