|A Power-Aware, Application-Based, Performance Study Of Modern Commodity Cluster Interconnection Networks|
(. Vol , Nr. , In Proceedings of the 23rd IEEE International Parallel & Distributed Processing Symposium, CAC'09 Workshop, presented in Rome, Italy, pages , , ISSN: 1530-2075, ISBN: 978-1-4244-3750-4, May 2009)
AbstractMicrobenchmarks have long been used to assess the performance characteristics of high-performance networks, with the assumption that microbenchmark results correlate to the parallel performance of real applications. To assess the applicability of microbenchmarks, and to study commodity networks in real-world situations, this paper reports the results of performance studies using real applications in a strictly controlled environment with different networks. In particular, we compare the performance of Myrinet and InfiniBand, and analyze them with respect to microbenchmark performance, real application performance and power consumption.
