1China’s Massive Sunway TaihuLight Dominates List of Supercomputers
China toppled the United States from its position atop the global supercomputing world. Here’s a look at the top 10 fastest systems.
2The Beast That Is Sunway TaihuLight
The newest system in the top spot delivers 93 petaflops/second (quadrillions of calculations per second) of performance and is more than twice as fast and three times as efficient as the Tianhe-2 supercomputer it replaced as No. 1. It uses 40,960 Chinese-developed Sunway SW26010 chips and holds more than 10.6 million cores.
3The Reign of Tianhe-2 Is Over
The system at the National Supercomputer Center in China was No. 1 for six consecutive lists, before Sunway TaihuLight came along. Tianhe-2 is powered by Intel’s Xeon E5-2692 processors, Xeon Phi coprocessors and more than 3.1 million cores, and provides 33.86 petaflops of performance.
4Titan Stands Tall at No. 3
The fastest system on the list is Titan, a Cray supercomputer running Opteron processors from Advanced Micro Devices and Nvidia GPU accelerators. It delivers more than 17 petaflops of performance. It’s housed at the Oak Ridge National Lab.
5IBM’s Fastest Is Sequoia
The Blue Gene/Q supercomputer, housed at the Lawrence Livermore National Lab and running on Big Blue’s Power chips, is powered by more than 1.5 million cores and delivers 17.1 petaflops.
6K Computer Still on the List, as Its Successor Makes News
The system at the Riken facility in Japan, once the most powerful of its kind, remains among the top five at 10 petaflops. Fujitsu officials at the show made news when they said that the next system—dubbed “Post-K”—will run on ARM-based processors rather than the SPARC64 architecture that powers the K computer.
7Mira Marks IBM’s Second System in Top 10
The BlueGene/Q supercomputer, at the Argonne National Lab, provides more than 8.5 petaflops of performance. In all, IBM has 38 systems on the Top500 list, making it number five among vendors.
8Cray and Its Trinity
The supercomputer, based on Cray’s Intel-powered XC40 system, brings 8.1 petaflops of performance to the Los Alamos National Lab. Cray has 60 systems on the Top500 list, with five in the top 10.
9Piz Daint Includes GPU Accelerators
The Cray-based system at the Swiss National Computing Centre runs on Intel’s Xeon E5-2670 chips and Nvidia’s K20x GPU accelerator. Ninety-three supercomputers on the list use GPU or coprocessor accelerators to improve performance while keeping power consumption down.
10Hazel Hen Runs on Intel Processors
The supercomputer at the High Performance Computing Center in Germany is based on Cray’s XC40 systems running Intel’s Xeon E5-2680 v3 processors. Ninety-one percent of the supercomputers on the list—or 455—are powered by Intel processors.
11Shaheen II Is the Fastest in the Middle East
Shaheen II, which uses Cray’s XC40 systems and Xeon E5-2698 v3 processors, puts the Middle East into the top 10, at 5.5 petaflops of performance.
