IBM's Fermi is one of five systems the company has ranked on the top 10 list. That's right -- half of the 10 fastest supercomputers in the world come from IBM! Of course, they're all different, and the IBM Sequoia in the first spot is dramatically faster than many other systems.
Fermi uses more than 163,000 processor cores and, like JuQUEEN, is a brand new European supercomputer set up in June 2012. It's the fastest supercomputer in Italy and is installed at Cineca, a nonprofit consortium of 54 Italian universities. Fermi maxes out at more than 2 petaflops of performance, making it the second fastest European supercomputer on the list.
