Abstract :
We explore the design of optimal deadlock recovery-based fully adaptive routers by evaluating promising internal router crossbar designs. Unified and decoupled crossbar designs aimed at exploiting the full capabilities of adaptive routing are evaluated by analyzing their effect on overall network performance. We show that an enhanced hierarchical crossbar design that supports routing locality in virtual network class achieves highest performance with relatively low cost
