Douglas Eadline writes “Real-world application performance depends on various HPC cluster elements – the processor, the memory, and the interconnect. The interconnect controls the data transfer between servers, and has a large influence on the CPU efficiency and memory utilization. Because clusters can vary in design, high performance interconnects are often compared using artificial benchmarks. The important question is how well these artificial benchmarks translate into real-world performance. This article attempts to answer this question buy taking a look at the real-world performance of Mellanox and Qlogic Interconnects.”
