Most powerful computer Overview
China has now recently build a brand new super computer. It is recognized by researchers as the world’s most powerful machines. The Sunway TaihuLight is set at the National Supercomputing Center in south part of China. The computer can perform up to around 93,000 trillion calculations per second. According to world records, its perfromance speed is twice as fast and three times as efficient as the previous leader Tianhe-2, which is also from China. Jack Dongarra, a university researcher, stated that the main usages of the computer is advanced manufacturing, weather forecasting and big data analytics. Based on researches from Top500, China has made a considerable development in computer over the past 10 years. China has come further and faster than any other country in the history of super computing. Other top computers are from some EU countries and Asia regions.
Most powerful computer System
The processor chip is composed of 4 core groups (CGs) and 64 Computing Processing Elements (CPEs). The complete system has a theoretical peak performance of 125.4 Pflop/s with 10,649,600 cores and 1.31 PB of primary memory. Each of the four MPE, CPE, and MC have access to 8 GB of DDR3 memory. The total system has 40,960 nodes for a total of 10,649,600 cores and 1.31 PB of memory. The MPE’s and CPE’s are based on a RISC architecture, 64-bit, SIMD. The MPE performance management, communication, and computation while the CPEs mainly perform computations. The cycle time for the cores is 1.45 GHz, so a CPE core has a peak performance of 8 flops/cycle * 1.45 GHz or 11.6 Gflop/s and a core of the MPE has a peak performance of 16 flops/cycle * 1.45 GHz or 23.2 Gflop/s. Non-volatile memory is not used in the system.
Most powerful computer Conclusion
Overall I am very impressive with over 10 million cores and a peak performance of 125 Pflop/s. The ratio of floating point operations per byte of data is 22.4 Flops. In contrast, the Intel Knights Landing processor with 7.2 Flops. The Sunway TaihuLight system pointed out that the significant progress that China has made in the domain of designing and manufacturing super scale computer systems. According to the Chinese domestic plan for the next generation of high performance computers, the country will develop an new computer during 2016 to 2020.
