The use of high-radix routers leads to lower cost and better performance, but high-radix networks present many difficult challenges. This thesis explores challenges in scaling to high-radix routers, including topology, routing, and router microarchitec-ture.

In this pa-per, we examine the most commonly used organization of a router, the input-queued crossbar, and the different microar-chitectural issues that arise when we try to scale them to high-radix routers such as switch and virtual channel allo-cation.

Apr 28, 2013 · A high radix is just an extension of a nasal hump. During the rhinoplasty procedure the hump and a high radix are removed to give new definition to the nasal bridge line.

butterfly can scale more effectively and also exploit high-radix routers. Routing algorithms on the flattened butterfly are compared and we show that global-adaptive routing is needed to load-balance the topology. We show that greedy implementations o

Dec 3, 2006 · High-radix, single-chip routers have emerged as efficient building blocks for interconnection networks. Researchers believe that hierarchical switch architectures are needed at high radices as crossbars scale with the square of the router radix.

One of the fundamental tradeoffs in NoC design is the radix of its constituent routers. While high-radix routers enable a richly connected and low diameter network, low-radix routers allow for a small silicon area.

In this article, we propose scalable router microarchitectures that leverage a network within the switch design of the high-radix routers themselves. These alternative designs lower the wiring complexity and buffer requirements.

Jun 8, 2005 · However, increasing the radix (or degree) of a router raises several challenges as internal switches and allocators scale as the square of the radix. This paper addresses these challenges by proposing and evaluating alternative microarchitectures for high radix routers.

Stanford researchers have developed an alternative microarchitecture for high radix routers. This hierarchical organization of high radix routers improves throughput up to 60% higher than conventional crossbar architecture and provides 40% area savings over fully …

Jun 11, 2022 · In this work, we propose a novel global adaptive routing that we refer to as dynamic global adaptive routing that adjusts the routing decision algorithm through a dynamic bias based on the network traffic and congestion to maximize performance.
