New Chinese supercomputer is the world's fastest, with speeds equivalent to 338 million ordinary PCs put together | Mail Online
 Arik Hesseldahl: China Retakes Supercomputing Crown With a Lot of American Chips - Arik Hesseldahl - News - AllThings - newsle

before any of you reading in the U.S. get all bummed about the decline of American technical superiority, consider this: Its main computing engine was made in America, and America retains the lead for total national supercomputer entries and total processing power.

Tianhe-2 has 16,000 nodes, each containing two Intel-made Xeon Ivy Bridge processors and three Xeon Phi processors, bringing the total number of computing cores to 3.12 million. Its total performance is 33.86 petaflops using the LINPACK benchmark, which means it can conduct 33.86 quadrillion calculations per second.

I’ll write that number out so you can see all the zeros: 33,860,000,000,000,000.


That’s almost twice — but not quite — as powerful as Titan, which can do 17.59 petaflops. Titan runs on 560,640 processors, of which 261,632 are Nvidia-made accelerators. The rest are Opteron chips made by Advanced Micro Devices.

Source of the chips is left out of China news releases on the project.
