Say "bunch" and strive to keep your mind from graphics of massive, authorities-backed technological software or herds of caffeine intake-motivated grad individuals. Quite challenging. But in fact, most high performance computers (HPC) clusters are not anywhere in close proximity to large enough to meet the requirements as massive, are employed in professional situations, and operate on Gigabit Ethernet interconnects. Even inside the TOP500® Supercomputer Websites 24v din-rail mounted switching power supplies the number of clusters working Gigabit Ethernet is more than twice the number of clusters working InfiniBand. Undoubtedly, better rate and minimize latency can be wonderful for virtually any installation. But the performance needs for most software just don’t merit the top cost and labor-intensive maintenance of InfiniBand.
