The supercomputer is powered by more than 3.12 million Intel processor cores, but according to Top500 editor Jack Dongarra, “Most of the features of the system were developed in China, and they are only using Intel for the main compute part. That is, the interconnect, operating system, front-end processors and software are mainly Chinese.”
3Cray’s Titan Supercomputer Drops to No. 2
Titan, a Cray XK7 supercomputer powered by AMD’s Opteron chips and Nvidia GPU accelerators, hit the top of the list in November 2012, but was quickly bounced by Tianhe-2. It’s also among the most energy-efficient systems.
4Sequoia Is the Largest of Four BlueGene/Q Systems in the Top 10
Sequoia, first delivered to the Lawrence Livermore Lab in 2011, delivers 17.17 petaflops per second of performance and is armed with more than 1.57 million IBM Power cores. It also is highly energy-efficient.
5Fujitsu’s K Computer Drops to No. 4
The supercomputer, at the RIKEN Advanced Institute for Computational Science in Japan, is powered by 705,024 SPARC64 processing cores. It offers 10.51 petaflops per second of performance.
6Mira Is Another IBM BlueGene/Q Supercomputer
Mira is installed at Argonne National Laboratory, runs on 786,432 Power cores and delivers 8.59 petaflops per second of performance.
7Stampede Is Based on Dell PowerEdge Servers
