Cisco has published a new whitepaper that compares HPC application performance on 10 Gig Ethernet vs. InfiniBand.
Despite the high bandwidth and performance claims of InfiniBand, Cisco has demonstrated that 10 Gigabit Ethernet is a viable solution for HPC clusters. The powerful Cisco C200 M2 server combined with Cisco Nexus 5000 Series Switches and RDMA NICs provides a low-latency solution that meets or beats QDR InfiniBand in real application performance for leading HPC applications.
So readers, what do you think? Is this a fair comparison? Download the whitepaper (PDF).
