Say "bunch" and strive to keep your imagination from pictures of huge, authorities-funded clinical applications or herds of caffeine-fueled grad individuals. Pretty hard. But in fact, most good performance computing (HPC) clusters are nowhere close to large enough to be eligible as substantial, are used in business environments, and are powered by Gigabit Ethernet interconnects. Even within the TOP500® Supercomputer Websites sfp transceiver multi mode 2km the number of clusters running Gigabit Ethernet is far more than twice the number of clusters running InfiniBand. Definitely, better velocity and lower latency will be wonderful for virtually any installment. Nevertheless the performance needs for almost all applications just don’t value the high cost and labor-rigorous upkeep of InfiniBand.
