2010 MIT article: Why China's New Supercomputer Is Only Technically the World's Fastest; Peak performance doesn’t equal sustained performance, and the NVIDIA GPUs in the Tianhe 1A are especially bad at the latter. https://www.technologyreview.com/s/421584/why-chinas-new-supercomputer-is-only-technically-the-worlds-fastest/ move forward to 2017 MIT article: America Just Can’t Match China’s Exploding Supercomputing Power https://www.technologyreview.com/the-download/609468/america-just-cant-match-chinas-exploding-supercomputing-power/ TECH SUPERCOMPUTERS; China Now Has More Supercomputers Than Any Other Country http://time.com/5022859/china-most-supercomputers-world/ America second?
