and costs $1.1 Billion Dollars!
BUT, is it really the fastest?

Of the top 500 super computers, all but 21 run Linux, BSD or Unix. Only six run Windows.

An eight-petaflop Japanese supercomputer has grabbed the title of fastest computer on earth in the new Top 500 Supercomputing List to be officially unveiled at the International Supercomputing Conference in Hamburg today.
...
In contrast to many of other mega-machines in the list, the K Computer achieves the feat with not a single GPU in sight. The K Computer was built by Fujitsu, and contains more than 80,000 2GHz SPARC64 VIIIfx CPUs, each with eight cores, to deliver a total of more than 640,000 processing cores.
..
It draws a massive 9.89 megawatts. But given its gigantic processing output, it still manages to be the fourth most energy-efficient system in the 500, with a performance-per-watt rating of 825 megaflops per Watt. That compares to the average power efficiency among the 500 of 248 Mflop/W, up from 219 Mflop/W six months ago.

Cray this week released its fastest and most advanced supercomputer, which the company said can achieve a staggering 50 petaflops, or 50 quadrillion floating point operations per second.
...
Cray said it could have released the XK6 earlier, but that it took about a year and a half to create the software that could integrate the GPUs. The software of the XK6 consists of a Linux OS based on SUSE enterprise OS 11, layered with Cray's own programming,
...
Bolding said, "Cray has a very strong belief that it isn't just about putting together a bunch of pieces of hardware. If you look at Chinese GPU systems over the last few months, we haven't seen a lot of scientific results coming out of those systems. That is probably because those systems, while they're put together with a bunch of very powerful hardware, don't have the software to run scientific applications at scale. That's really where our advantage is."
