Abstract
Interconnection networks fall into two different classes: (1) low-radix networks, and (2) high-radix networks. High-radix networks mainly include fat-tree networks, and dragonfly related networks. Dragonfly related networks include the 1D dragonfly networks, 2D Slingshot networks, dragonfly+ networks and others. The 1D dragonfly networks consist of completely connected router groups, where each pair of router groups has one or multiple global optical connection. Each pair of routers in the same router group has a single local connection. The Slingshot networks replace the router group with a flattened butterfly 2D connected group, where every two groups can be connected by one or multiple global connections. The dragonfly+ network is an enhanced 1D dragonfly network, where each router group contains two sub-groups of switches: one called leaf switches, and the other are spine switches. The spine switches are directly connected to the spine switches of the other router groups while the leaf switches are connected to the spine switches in the same group and the servers. The speaker presents efficient routing algorithms, network connection schemes, and collective communication operations in different high-radix networks.
