The Tianhe-2, also known as the Milky Way 2, is the creation of China's National University for Defense Technology. The device was built to "provide an open platform for research and education and provide high performance computing service for southern China," according to the University of Tennessee's Jack Dongarra. Dongarra helped compile a list of the Top 500 supercomputers in the world, and wrote a report on this latest machine.
The Tianhe-2 reportedly has a storage of 12.4 petabytes and memory of 1.4 PB. In case you're not familiar, a petabyte is the equivalent of 1,000 terabytes, or 1,000,000,000,000,000 bytes. Yes, that's five commas.
