Cost-efficient Dragonfly Topology for Large-scale Systems
Abstract
It is more efficient to use increasing pin bandwidth by creating high-radix routers with a large number of narrow ports instead of low-radix routers with fewer wide ports. Building networks using high-radix routers lowers cost and improves performance, but also presents many challenges. The dragonfly topology minimizes network cost by reducing the number of global channels required.
