If someone says "supercomputer,"
your mind may jump to Deep Blue, and you wouldn't be alone. IBM's
silicon chess wizard defeated grandmaster Gary Kasparov in 1997,
cementing it as one of the most famous computers of all time (some
controversy around the win helped, too). For years, Deep Blue was the
public face of supercomputers, but it's hardly the only all-powerful
artificial thinker on the planet. In fact, IBM took Deep Blue apart
shortly after the historic win! More recently, IBM made supercomputing
history with Watson, which defeated "Jeopardy!" champions Ken Jennings
and Brad Rutter in a special match.
Brilliant as they were,
neither Deep Blue or Watson would be able to match the computational
muscle of the systems on the 2012 TOP500 list. TOP500 calls itself a
list of "the 500 most powerful commercially available computer systems
known to us." The supercomputers on this list are a throwback to the
early computers of the 1950s -- which took up entire rooms -- except
modern computers are using racks upon racks of cutting-edge hardware to
produce petaflops of processing power.
Your home computer probably runs on four processor cores. Today's supercomputers use more than a million.
TOP500
relies on the Linpack benchmark, which feeds a computer a series of
linear equations to measure its processing performance. The June 2012
list sees IBM's Sequoia on top of the world. Every six months, TOP500
releases a list, and a few new computers rise into the ranks of the
world's fastest. Here are the current champions. Read on to see how
they're putting their electronic mettle to work.
10. Nebulae (China)
Nebulae, made by Chinese supercomputer manufacturer Dawning, has been
in the top 10 of the TOP500 list since June 2010. The computer has slid
from a strong starting rank of No. 2 down to No. 10, but being the
tenth most powerful computer in the world is still pretty good, right?
With only 120,000 Intel Xeon computer cores, the Nebulae performs at
more than 1.27 petaflops and is the second most powerful computer in China.
Nebulae
operates at the National Supercomputing Centre in Shenzhen. Part of its
speed comes from a number of Nvidia graphics processing units (GPUs)
that help accelerate performance. Nvidia's GPUs also helped China's
Tianhe-1A, currently in fifth place, to best many other super-powerful
computers.
Like most supercomputers, Nebulae is tasked with doing
what it does best: performing calculations very, very quickly. Its time
is reportedly divided between high speed calculations and cloud
calculations.
9. Curie Thin Nodes (France)
France's Curie thin nodes, created by technology company Bull,
exemplify how much supercomputer design can vary, even with a lot of the
same parts under the hood. The ninth computer on the top 10 list uses
Intel's Xeon processors, but runs on a unique Bull supercomputing suite,
instead of the Linux operating system used by most computers on the list.
The
computer's spot on the list is also impressive, given that it uses a
mere 80,000 processor cores. That's 40,000 fewer than the Nebulae! The
Curie system peaks at a performance of around two petaflops. According
to the French Atomic Energy and Alternative Energies Commission, the
Curie computer system is open to scientists through the PRACE research
infrastructure, making it one of the most powerful computers in Europe
open to research.
8. JuQUEEN (Germany)
JuQUEEN is the first of four computers on the top 10 list running on
IBM's powerful BlueGene/Q platform, with max performance of around 1.6
petaflops. While many computers on the list have been around for the
last couple years, the JuQUEEN is brand new. It's actually a replacement
for another system, JUGENE, which was the ninth fastest system on the
November 2010 TOP500.
Once JuQUEEN is coupled with another
BlueGene/Q supercomputer in October 2012, researchers at the
Jülich-Aachen Research Alliance will be able to carve out some time with
one of the most powerful supercomputers in the world. Researchers have
to submit proposals for projects to justify using some of JuQUEEN's
cores.
7. Fermi (Italy)
IBM's Fermi is one of five systems the company has ranked on the top
10 list. That's right -- half of the 10 fastest supercomputers in the
world come from IBM! Of course, they're all different, and the IBM
Sequoia in the first spot is dramatically faster than many other
systems.
Fermi uses more than 163,000 processor cores and, like
JuQUEEN, is a brand new European supercomputer set up in June 2012. It's
the fastest supercomputer in Italy and is installed at Cineca, a
nonprofit consortium of 54 Italian universities. Fermi maxes out at more
than 2 petaflops of performance, making it the second fastest European
supercomputer on the list.
6. Jaguar (United States)
The Jaguar is a change of pace. While the last three systems have
been newcomers to the TOP500 list, the Jaguar is an old veteran: It's
been on the list since the second half of 2009! That's practically
ancient in the supercomputer world, but the Jaguar, located in Oak
Ridge, Tennessee, is a powerhouse. It was the fastest supercomputer in
the world on the November 2009 and June 2010 lists. It spent the next
year and a half at second and third place before sliding down to sixth.
Jaguar
is one of the rare few computers in the top 10 to run on AMD
processors, and it also utilizes a special version of Linux,
the Cray Linux Environment, built for supercomputers. Supercomputer
manufacturer Cray built the Jaguar for $104 million and upgraded it in
2012 to keep it competitive. The company increased Jaguar's processor
count from about 225,000 to nearly 300,000, bringing its processing
power from about 2.3 to 2.6 petaflops.
5. Tianhe-1A (China)
China's electronic pride and joy, Tianhe-1A, was the fastest
supercomputer in the world in 2010. It slipped to second place in 2011
and now sits in the number five spot. Like the Nebulae, Tianhe-1A's
performance is bolstered by graphics card
maker Nvidia. It uses 168 Nvidia Tesla M2050 GPUs to offload work from
its 14,336 Intel Xeon processors. In total, it runs on more than 180,000
computer cores.
Unlike
Nebulae, Tianhe-1A is not made by Chinese computer company Dawning.
Instead, it comes from China's National University of Defense
Technology. It operates at the National Supercomputing Center at
Tianjin. Tianhe-1A can crank out 2.5 petaflops of performance, making it
twice as fast as China's next-best supercomputer.
4. SuperMUC
Despite being another IBM system using Intel's Xeon processors, the
SuperMUC is unique in a couple different ways. Located in Germany's
Leibniz Supercomputing Centre, the SuperMUC uses a new hot-water cooling
system to keep the computer's brain
from frying while it's performing billions upon billions of operations.
The SuperMUC is another new entry on the list and performs at up to 3
petaflops, thanks to about 150,000 processing cores.
Efficiency is
what really sets the SuperMUC apart: IBM says it's 40 percent more
energy efficient than an air-cooled system would be. They claim the
water removes heats 4,000 times more efficiently than air. Thanks to its
cutting-edge hardware, the SuperMUC is Germany's fastest supercomputer.
In fact, it's the fastest supercomputer in Europe, period.
3. Mira (United States)
Here's where supercomputers get serious. The first seven entries on
the list were fast, but not fast enough for top-three ranking. IBM's new
Mira, which becomes fully operational in 2013, peaks at a performance
of 8 petaflops. That's more than twice as fast at the SuperMUC in
Germany.
Mira runs on 768,000 processor cores. It's located at the
Argonne National Laboratory, a research laboratory run for the United
States Department of Energy. It uses IBM's BlueGene/Q platform and
replaces an older IBM system, Intrepid, which ranked fourth on the list
in 2008.
Researchers who submit proposals for the Innovative and
Novel Computational Impact on Theory and Experiment program will be able
to claim processor time on Mira. Sixty percent of the computer's
capacity will go to their research, while 30 percent will go towards the
Advanced Science Computing Research Leadership Computing Challenge. The
final 10 percent will be reserved for urgent, time-sensitive
computations.
2. K computer (Japan)
Fujitsu's K computer, the only supercomputer in Japan that made the
top 10, is an incredibly powerful machine. It reigned as the fastest
supercomputer in the world on both 2011 lists and now sits at No. 2 with
a huge gulf in performance over IBM's new Mira. It can perform at up to
11 petaflops.
The K Computer is located at Japan's RIKEN Advanced
Institute for Computational Science, where it performs scientific
operations including global disaster prevention, meteorology and medical
research.
Unlike many of the other supercomputers on the list, it doesn't run on
IBM architecture. The K computer uses Fujitsu's own SPARC64 VIIIfx
octo-core processors. Seven hundred and five thousand computer cores
help it churn through operations at an incredible pace.
But believe it or not, the fastest supercomputer in the world is leaps and bounds more powerful than the K computer.
1. IBM Sequoia (United States)
This is the Big Kahuna, the champion on the June 2012 TOP500 list.
IBM's Sequoia is the fastest computer in the world (at least, the
fastest visible to the public) thanks to 1.6 million processing cores
that can crank out an incredible 16.3 petaflops of performance.
Wondering just how incredible that is?
Well, if we look back a
mere half decade, to 2008, IBM's Roadrunner made history (and grabbed
the top slot) for cracking 1 petaflop, aka performing 1,000 trillion
operations per second.
IBM said Roadrunner was equivalent to 100,000 of 2008's laptops in
performance. And Sequoia is 16 times as fast! Sequoia is one of four
computers on the June 2012 list running on the BlueGene/Q IBM design, an
18 core 1.6GHz chip. That's not an especially fast clock speed by
today's standards, but with 96 racks of chips, the performance really
adds up.
What's
Sequoia doing with all that speed, anyway? For a while, IBM has
bragging rights -- Sequoia is 55 percent faster than the second fastest
computer on the list. But they're putting Sequoia to work, of course.
The computer operates at the U.S. Department of Energy's National
Nuclear Security Administration at the Livermore National Laboratory.
The computer's doing important work: One of its responsibilities is
simulating nuclear explosions.
