France's Curie thin nodes, created by technology company Bull, exemplify how much supercomputer design can vary, even with a lot of the same parts under the hood. The ninth computer on the top 10 list uses Intel's Xeon processors, but runs on a unique Bull supercomputing suite, instead of the Linux operating system used by most computers on the list.
The computer's spot on the list is also impressive, given that it uses a mere 80,000 processor cores. That's 40,000 fewer than the Nebulae! The Curie system peaks at a performance of around two petaflops. According to the French Atomic Energy and Alternative Energies Commission, the Curie computer system is open to scientists through the PRACE research infrastructure, making it one of the most powerful computers in Europe open to research.
