Kina 1petaflopos 8700db sajat(ShenWei SW1600) processzora epulo gepet epitett

The announcement was made this week at a technical meeting held in Jinan, China, organized by industry and government organizations. The new machine, the Sunway BlueLight MPP, was installed in September at the National Supercomputer Center in Jinan, the capital of Shandong Province in eastern China.

The Sunway system, which can perform about 1,000 trillion calculations per second — a petaflop — will probably rank among the 20 fastest computers in the world. More significantly, it is composed of 8,700 ShenWei SW1600 microprocessors, designed at a Chinese computer institute and manufactured in Shanghai.
...
Photos of the new Sunway supercomputer reveal an elaborate water-cooling system that may be a significant advance in the design of the very fastest machines. “Getting this cooling technology correct is very, very difficult,” said Steven Wallach, chief scientist at Convey Computer, a Richardson, Tex., supercomputer firm. “This tells me that this is a serious design. This cooling technology could scale to exaflop. They are in the hunt to win.”

Given that 8,700 chips were used to attain a petaflop of peak performance, each ShenWei SW1600 processor should deliver about 115 gigaflops, which is pretty much on par with a late-model quad-core x86 processor.
...
According to reports from the technical conference, the new super consumes just one megawatt of power. If true, that would be less than half power used by the one petaflop Blue Gene/P JUGENE system in Germany, one of the most energy efficient CPU-based supercomputers in production today.

abszolut nem ertek hozza, de miert nem lat ezekbol a csoda-processzorokbol semmit a vilagnak ez a fele?

Azt írják, hogy valószínűleg benne van az első 20-ban. Egy hasonló teljesítményű géphez viszonyítva, kb. fele annyit fogyaszt. Elég sz@r lehet ez a hasonló teljesítményű gép, ha egy három generációval lemaradt gép jobb fogyasztási paraméterrel rendelkezik. :-)

ShenWei SW1600 a wiki szerint 16 core, 2 FPU unit per core, es 1.1Ghz -n megy, mikozben 140GFLops-ot szamol.
140(GFLOPS)/16(core)/1.1(Ghz)/2(FPU)=3.97727272727272727272 ~ 4.
