What are the high performance network plans for your next cluster?

Will be moving to 10 GigE

Staying with basic GigE because cost/performance is fine

Waiting because 10 GigE is still too expensive

Waiting because I need to see 10 GigE benchmarks

Trying to decide between InfiniBand and 10-GigE

Application performance is one of the most significant factors in the use of clusters in high-performance computing (HPC) environments. A number of variables affect performance, including node configuration, interconnect and switching fabric types and configuration, protocol offload technologies, storage and file system types, and the application characteristics. Many application types can be defined as HPC, and the characteristics of each influence the choice of interconnect and fabric.

This document presents a comparative analysis of the performance of LS-DYNA, a finite element analysis application, using two interconnect and fabric technologies: Gigabit Ethernet and Cisco InfiniBand.
