The benchmark measures real-world performance – but in theory the machine can boost that to a “peak performance” of 54.9 petaflop/sec.
The machine uses a total of 3.12 million processor cores that use Intel’s Ivy Bridge and Xeon Phi chips. It operates at the speed of 33.86 petaflop/sec which is equivalent to 33,860 trillion calculations per second. Theoretically the machine can reach the peak performance of 54.9 petaflop/sec.
Apart from processors and coprocessors, Tianhe-2 is entirely of Chinese make. That is, the interconnection network, Kylin operating system, front-end processors and software are made in China.
According to the latest list of 500 supercomputers, US made Titan and Sequoia ranked second and third respectively while Japanese K computer came down to fourth place.
Seeing the current trend the supercomputers likely to break exaflop/s barrier in five years. The Human Brain Project, for example, needs exascale computing power to build a complete digital model of the brain. The Square Kilometer Array radio telescope is ready to use an exascale computer to link a 3,000 kilometer array, 50 times as sensitive and 10,000 times faster than any telescope in the world today.
