Tianhe-2 (Milky Way-2), a system developed by China’s National University of Defense Technology (NUDT) and deployed at the National Supercomputer Center in Guangzho, China remains the No. 1 system with 33.86 petaflop/s (Pflop/s) on the Linpack benchmark. The system currently has 16,000 nodes, each with two Intel Xeon Ivy Bridge processors and three Xeon Phi processors for a combined total of 3,120,000 computing cores. It features a number of Chinese-developed components, including the TH Express-2 interconnect network, front-end processors, operating system and software tools. The Tianhe-2 uses the Kylin Linux operating system. The power consumption of Tianhe-2 while running Linpack was 17.8 MW.
The first version of what became today’s TOP500 list started as an exercise for a small conference in Germany in June 1993. Out of curiosity, the authors decided to revisit the list in November 1993 to see how things had changed. About that time they realized they might be on to something and decided to continue compiling the list, which is now a much-anticipated, much-watched and much-debated twice-yearly event.
The TOP500 list is compiled by Erich Strohmaier and Horst Simon of Lawrence Berkeley National Laboratory; Jack Dongarra of the University of Tennessee, Knoxville; and Martin Meuer of Prometeus, Germany.
