The 500th fastest supercomputer is Baku, a research machine located in Stuttgart, Germany.
Clocking in at 60 trillion calculations per second, it was in position No. 305 just six months ago. When it was built just two and a half years ago, it was the 77th fastest. That's how fast these machines become outdated.
The supercomputer, built by Cray, is one of just five systems in the Top 500 to run Windows. The vast majority of systems run the open-source Linux operating system, but a small handful feature other OS's, including Microsoft's lesser-known high-performance computing version of Windows, called Windows HPC 2008.
Jaguar, the Department of Energy's supercomputer, is bigger, faster, and much louder that you'd expect.
