Abstract
The Cray T3D uses a bidirectional, 3D torus interconnection network. Virtual channels are used both to prevent deadlock, and to improve network performance. This paper describes the Cray T3D network and introduces the concept of virtual channel balance. We show that balancing the traffic carried by each virtual channel can significantly improve network performance. We also discuss a technique, employing simulated annealing, for assigning virtual channels to routes in order to improve virtual channel balance.
