Say "cluster" and attempt to keep the brain from photos of huge, government-backed clinical programs or herds of caffeine-motivated grad students. Quite challenging. But in fact, nearly all high end processing (HPC) clusters are not anywhere around large enough to meet the requirements as massive, are used in professional surroundings, and are powered by Gigabit Ethernet interconnects. Even in the TOP500® Supercomputer Web sites 1200061 the quantity of clusters working Gigabit Ethernet is more than increase the quantity of clusters working InfiniBand. Definitely, higher rate and reduce latency will be wonderful for just about any installation. But the overall performance demands for many software just don’t value the high cost and labor-intense repair of InfiniBand.
