Top500.org recently released updated statistics about the fastest supercomputers in the world. They do this twice per year, and every time the reports make computing enthusiasts drool with mind-boggling performance numbers. You think your souped-up server or gaming rig is fast? Think again.
We cherry-picked some of the more interesting numbers, and made a few additional calculations for your reading pleasure. Enjoy.
- 548,352 – the number of CPU cores in the K Computer in Japan, the world’s currently fastest supercomputer. It’s the result of having 68,544 SPARC64 VIIIfx CPUs with eight cores each.
- 1,820,352 – the combined number of CPU cores in the top 10 supercomputers
- 672 – The number of computer racks that make up the K Computer (one is seen on the image for this post).
- 8.2 petaflops – The computing performance of the K Computer. It’s more powerful than the five next systems (i.e. position 2-6) combined.
- 8,200,000,000,000,000 – 8.2 petaflops written out as floating point operations per second (8.2 quadrillion instructions per second).
- 2.6 petaflops – The computing performance of the second-fastest supercomputer, the Tianhe-1A in China.
- 20.3 petaflops – The combined computing performance of the top 10 supercomputers.
- 1.04 petaflops – The computing performance of the “slowest” of the top 10.
- 9.9 megawatt – The power consumption of the K Computer.
- $10 million – The yearly power costs for the K Computer.
- 42.8 megawatt – The combined power consumption of the top 10 supercomputers.
- 40,000 – The number of homes that amount of electricity could power.
- 5 – Number of US supercomputers in the top 10. Japan has 2, China has 2, and France has 1.
A cool aside regarding the K Computer is that it isn’t even fully constructed yet, and it’s already outperforming everything out there by a huge margin. Its computing power is roughly the equivalent of a million linked desktop computers. Quite a comeback for Japan. This is the first time they’ve held the number one spot since 2004, when the Earth Simulator ruled the pack.

Perceptions matter, and the perception of Nokia in the news, on the web, and in the minds of many, is that things aren’t going that well. Even in the Pingdom office, we hear “Nokia is doomed,” but do the numbers support this belief?
Looking at the statistics, Symbian leads the mobile operating system race with just over 30% of web browsing traffic. That’s down slightly from late last year, when we noted that Symbian finished 2011 as the top mobile operating system, with almost 34% of the mobile OS market.
What is even more interesting, however, is that Nokia is also ahead when we look at figures for all the mobile handset vendors. In fact, Nokia is way ahead of Apple, and Android lags far behind.

Pingdom’s Podcast is a weekly show about Internet, web, security, and mobile stuff.
In this show, we talk mainly about Distributed Denial of Service attacks. Some fresh research shows an increase in smaller, more targeted DDoS attacks, and hacker group Anonymous has vowed to take down the Internet by launching a DDoS attack on the 13 root DNS servers.

Every Friday we bring you a collection of links to places on the web that we find particularly newsworthy, interesting, entertaining, and topical. We try to focus on some particular area or topic each week, but in general we will cover Internet, web development, networking, performance, and other geeky topics.
This week we bring you a collection of articles focusing on OpenStack.

By some measures, more than 7 billion people now inhabit the world, and more than a third of us are on the Internet. But how many are added each day, each week, or each minute? We think we have a pretty good idea.
Read on for some pretty amazing numbers.

Why the need for such fast machines? Can’t scientists simulate earthquakes with networked PCs in an office or university?

How many of those super computers run Linux?

@Dan – half million of PCs in an office or university? Must be a large one.

@Leon: Many of these supercomputers run Linux. See http://en.wikipedia.org/wiki/Supercomputer#Operating_systems

@Dan: These machines are a kind of computer clusters. They *are* networked computers, with a very fast interconnected ‘network’. However a typical network becomes a bottleneck when dealing with large amounts of data I/O, so these clusters rely special internal networks (usually referred to as ‘interconnects’).
If you were to attempt this level of computation with common kinds of networked computers (With independent power supplies, hard drives, etc) , your systems would be much more expensive and less reliable then these super computers.

Great computers! I think they should use fiber optics in cabling to save some amount of electricity.
