Performance Evaluation of I/O Traffic and Placement of I/O Nodes on a High Performance Network
by Salvador Coll, Fabrizio Petrini, Eitan Frachtenberg, Adolfy Hoisie — 2002 — In Workshop on Communication Architecture for Clusters 2002 (CAC ’02
…A common trend in the design of large-scale clusters is to use a high-performance data network to integrate the processing nodes in a single parallel computer. In these systems the performance of the interconnect can be a limiting factor for the input/output (I/O), which is traditionally bottlenecke…

Performance Evaluation of the Quadrics Interconnection Network
by Fabrizio Petrini, Adolfy Hoisie, Wu-chun Feng, Richard Graham — 2001 — Journal of Cluster Computing
…We present an initial performance evaluation of the Quadrics interconnection network (QsNET). We describe the main hardware and software features of QsNET of relevance to the system designer and to the end user. Actual benchmarks are performed on an experimental Linux cluster. The preliminary analys…
