  Network Topologies for HPC: Fat-Trees, Dragonfly, Torus, and the Cost-Diameter-Bandwidth Optimization

  2024-08-31

  A rigorous survey of HPC network topologies—fat-tree (InfiniBand), Dragonfly (Cray Cascade), torus (Blue Gene), Slim Fly—analyzing the fundamental tradeoffs in cost, diameter, bisection bandwidth, and fault tolerance.
