A New Scalable and Cost-Effective Congestion Management Strategy for Lossless Multistage Interconnection Networks

J. Duato, I. Johnson, J. Flich, F. Naven, P. Garcia, T. Nachiondo
11th International Symposium on High-Performance Computer Architecture  
In this paper, we propose a new congestion management strategy for lossless multistage interconnection networks that scales as network size and/or link bandwidth increase.  ...  This is achieved in a scalable manner by using separate queues for congested flows. These are dynamically allocated only when congestion arises, and deallocated when congestion subsides.  ...  Conclusions In this paper we have proposed RECN, a new strategy for congestion management in lossless interconnection networks, also describing the most relevant implementation details for multistage interconnection  ...

2005 Lecture Notes in Computer Science  
The new results show that DBBM with modulo-4/8 mapping performs very well for only a fraction of the VOQ cost.  ...  To improve VOQ's scalability we have proposed the Destination-Based Buffer Management (DBBM), a scheme that compares well with VOQ.  ...  Acknowledgments We are indebted to Ton Engbersen and Ronald Luijten for significant contributions and careful review.  ...

FBICM: Efficient Congestion Management for High-Performance Networks Using Distributed Deterministic Routing [chapter]

Jesús Escudero-Sahuquillo, Pedro García, Francisco Quiles, Jose Flich, Jose Duato
2008 Lecture Notes in Computer Science  
We propose a novel congestion management technique for distributed tablebased routing. The mechanism relies on additional congestion information located at routing tables.  ...  One way to reduce both problems is using smaller networks with adequate congestion management mechanisms.  ...  However, none of them are suitable for modern interconnection networks due, respectively, to the high cost and consumption of current network components and to the lossless character of these networks.  ...

Adaptive Routing Strategies for Modern High Performance Networks

Patrick Geoffray, Torsten Hoefler
2008 2008 16th IEEE Symposium on High Performance Interconnects  
Our best adaptive routing scheme is able to increase the effective bisection bandwidth to 77% for 512 nodes and 100% for smaller node counts.  ...  Our experiments show that the effective bisection bandwidth of a non-blocking 512-node Clos network is as low as 38% if the network is routed statically.  ...  Acknowledgments Computation for the work described in this paper was supported by the University of Southern California Center for High-Performance Computing and Communications (www.usc.edu/hpcc).  ...

2020 arXiv   pre-print
We first develop a taxonomy of different forms of support for multipathing and overall path diversity. Then, we analyze how existing routing schemes support this diversity.  ...  Many low-diameter topologies such as Slim Fly or Jellyfish that substantially reduce cost, power consumption, and latency have been proposed.  ...  237] , general data center networking for clouds [226] , congestion management [120] , reconfigurable data center networks [81] , and transport protocols [207] , [182] .  ...
