Powered by independently-designed eight-core processors and a ultra-multi-port Gigabit Ethernet switching chip, the high-performance supercomputer “KD-90” was developed in December by academician Chen Guoliang with help from the China University of Science and Technology and a team from Shenzhen University, according to a Chinese tech newspaper's report.
Equipped with 10 eight-core processors, the Long Xin 3B, the KD-90 has a theoretical peak computing ability of one trillion times per second. The whole computing system, which consists of a front server, five compute nodes, two Gigabit Ethernet switches and a monitoring unit, is no bigger than a microwave oven. Compared to the KD-60, it uses 62 percent less power at 900w.
The supercomputer uses open-source software, some of which are mathematical function libraries especially optimized for the Long Xin 3B processor. The computer also features a visual monitoring and administrating operation system which is highly compatible, easy to upgrade, and user-friendly.
The supercomputer KD-90 can be used for mathematics, science and engineering , military and national security, and economics. According to the experts, the KD-90 is rated among the world’s most highly advanced systems in terms of programming models and networking applications in the computer and server markets.
Before KD-90, Chen and his team developed its predecessors, KD-50 and KD-60, in 2008 and 2010, both of which were powered by China’s self-designed processors, the Long Xin series.
