Toward Understanding Soft Faults in High Performance Cluster Networks [chapter]

Jeffrey J. Evans, Seongbok Baik, Cynthia S. Hood, William Gropp
2003 Integrated Network Management VIII  
Fault management in high performance cluster networks has been focused on the notion of hard faults (i.e., link or node failures).  ...  Network degradations that negatively impact performance but do not result in failures often go unnoticed. In this paper, we classify such degradations as soft faults.  ...  Acknowledgments This work was supported in part by the U.S. Department of Energy, under Contract W-31-109-Eng-38 and NSF 9984811.  ...

A Guided Tour through Data-center Networking

Dennis Abts, Bob Felderman
2012 Queue  
In recent years, Ethernet networks have made significant progress toward bridging the performance and scalability gap between capacity-oriented clusters built using COTS (commodityoff-the-shelf) components  ...  While the network plays a central role in the overall system performance, it typically represents only 10-15 percent of the cluster cost.  ...  Alternatively, implementing QoS (quality of service) policies to segregate traffic into distinct classes and provide performance isolation and high-level traffic engineering is a step toward ensuring that  ...
