Say "group" and strive to keep your thoughts from pictures of massive, federal government-funded clinical applications or herds of caffeinated drinks-fueled grad students. Rather tough. But in fact, the majority of high end processing (HPC) clusters are thin air near big enough to meet the criteria as huge, are utilized in industrial conditions, and are powered by Gigabit Ethernet interconnects. Even in the TOP500® Supercomputer Websites 1200080 the quantity of clusters jogging Gigabit Ethernet is much more than twice the amount of clusters operating InfiniBand. Certainly, greater speed and lower latency will be great for almost any set up. But the performance needs for most applications just don’t value our prime cost and labor-rigorous upkeep of InfiniBand.
