TIANHE-2:Worlds NO.1 super computer.Made by CHINA According to NUDT, Tianhe-2 will be used for simulation, analysis, and government security applications.[1] With 16,000 computer nodes, each comprising two Intel Ivy Bridge Xeon processors and three Xeon Phi coprocessor chips, it represents the worlds largest installation of Ivy Bridge and Xeon Phi chips, counting a total of 3,120,000 cores.[3] Each of the 16,000 nodes possess 88 gigabytes of memory (64 used by the Ivy Bridge processors, and 8 gigabytes for each of the Xeon Phi processors). The total CPU plus coprocessor memory is 1,375 TiB (approximately 1.34 PiB).[1] During the testing phase, Tianhe-2 was laid out in a non-optimal confined space. When assembled at its final location, the system will have a theoretical peak performance of 54.9 petaflops. At peak power consumption, the system itself would draw 17.6 megawatts of power. Including external cooling, the system would draw an aggregate of 24 megawatts. The computer complex would occupy 720 square meters of space.[1] The front-end system consists of 4096 Galaxy FT-1500 CPUs, a SPARC derivative designed and built by NUDT. Each FT-1500 has 16 cores and a 1.8 GHz clock frequency. The chip has a performance of 144 gigaflops and runs on 65 watts. The interconnect, called the TH Express-2, designed by NUDT, utilizes a fat tree topology with 13 switches each of 576 ports.[1] Tianhe-2 runs on Kylin Linux, a version of the operating system developed by NUDT. Resource management is based on Simple Linux Utility for Resource Management (SLURM).[1]
