Chinese 93-petaflop system takes No. supercomputer list




The Top500 list of supercomputers has a new leader. The Chinese system Sunway TaihuLight outclassed the Tianhe-2 with a Linpack score of 93 petaflops. The TaihuLight cluster is built around the Shenwei processor developed in China.

The Sunway TaihuLight at the National Supercomputing Center in Wuxi has more than ten million cores, a total of 10.6496 million. The processor of the cluster is the SW26010 64bit risc processor, which runs at 1,45GHz. This is a network-on-a-chip with four groups of 65 cores, a core for management and 64 computing cores. The chip is integrated an interconnect which allows processors to work together. A server rack of four times 256 pieces of 260core chip can thus function as a whole and the entire system covers forty racks. The cluster runs Sunway RaiseOS 2.0.5.

According to the Top500 organization shows the system that China does not need to rely on Western technology to participate in the highest echelons of the world’s most powerful computing systems. A single SW26010 offers a power of 3 teraflops, similar to the Intel Xeon Phi Knights Landing accelerator. For years, the Tianhe-2 was leading in the Top500, a cluster with Intel Xeon E5-2692 processors. It took in November last year 33.86 petaflops at a consumption of 17.8 megawatts. The Sunway TaihuLight is so over it, with lower consumption: 15.3 megawatts.

Netherlands is the Descartes supercomputer dropped from 68th to 80th place. This is not unexpected; the cluster will later this year, a major upgrade to the ‘national supercomputer’ with theoretical 1.8 petaflops have piloted a higher listing. On spot 154 is still a Dutch Xeon cluster at an undisclosed software and the same applies to position 358 .

Belgium is represented by two systems. On spot 195 is the BrEniac of the VSC and at position 414 is Zenobe’s Cenaero.
