In this video from the 2015 HPC Advisory Council Switzerland Conference, Dror Goldenberg from Mellanox presents: Adaptive Routing for Scalable Topologies.
Adaptive Routing has been added to the static routing capability available in previous switch families. InfiniBand supports moving traffic via multiple parallel paths. Adaptive routing dynamically and automatically re-routes traffic to alleviate congested ports. In networks where traffic patterns are more predictable, static routing has been shown to produce superior results. The InfiniScale IV architecture provides the best of both static and adaptive routing.
