Say "bunch" and try to keep the mind from images of huge, authorities-financed scientific software or herds of caffeine intake-powered grad individuals. Pretty challenging. However, nearly all good performance computer (HPC) clusters are not anywhere close to big enough to qualify as massive, are utilized in industrial situations, and operate on Gigabit Ethernet interconnects. Even inside the TOP500® Supercomputer Internet sites 24v din-rail mounted switching power supplies the number of clusters operating Gigabit Ethernet is a lot more than double the number of clusters working InfiniBand. Definitely, higher rate minimizing latency could be nice for virtually any set up. But the performance needs for many applications just don’t value our prime labor and cost-intensive maintenance of InfiniBand.
