Every six months, the TOP500 projectranks the world's most powerful computers - and right now, these are the top five machines the world has ever seen.

1. The slightly mysterious Chinese one: Tianhe-1A
China's supercomputer is currently the world's fastest: it can run at a sustained 2.5 petaflops (a petaflop is a thousand trillion floating point operations per second) thanks to its 186,368 cores and 229,376GB of RAM.
While the horsepower comes from off-the-shelf Intel and Nvidia chips, the New York Times saysthat the Chinese machine's speed is down to its interconnect, the networking technology that connects the individual nodes of the computer together, which is twice as fast as the InfiniBand technology used in many other supercomputers.
It's located in Shenzhen's National Supercomputing Centre, where it's used by universities and Chinese companies.

2. The one with a quarter of a million cores: Jaguar
Jaguar, a Cray XT5-HE
supercomputer located at the US Oak Ridge National Laboratory, has quite a few cores: TOP500 says there are nearly a quarter of a million since its most recent upgrade.
Jaguar's 224,162 cores come courtesy of a whole bunch of six-core Opteron chips, and its performance is a hefty 1.76 petaflops. Oak Ridge says it's the world's fastest supercomputer for unclassified research.

3. The other slightly mysterious Chinese one: Dawning Nebulae
When it launched in early 2010 the Chinese Dawning Nebulae supercomputer was the world's fastest, with performance of 1.27 petaflops, but it's already in third place thanks to Jaguar and China's own newer, faster Tianhe-1A. Like its sibling Nebulae is in the National Supercomputing Centre in Shenzhen.

4. The one with the rubbish name: TSUBAME 2.0
Tokyo's TSUBAME 2.0 offers similar performance to Jaguar - it peaks at 2.3 petaflops, with sustained performance of around 1.4 petaflops - but it's one-quarter of the size and uses one-quarter of the power thanks to its heavy reliance on Nvidia Fermi GPUs as well as Intel CPUs.
According to project lead Professor Satoshi Matsuoka, TSUBAME will really shine in climate and weather forecasting, biomolecular modelling and tsunami simulations.

5. The planet-saver: Hopper
Hopper is working on the big stuff: climate change, clean energy, astrophysics, particle physics... its home, the US Department of Energy's National Energy Research Scientific Computing Center, offers its services to more than 3,000 researchers in the fields of climate research, chemistry, new material development and other crucial fields.

Wetin dem dey use this kin machines do sef? I can only imagine!

Someday we will have one of these "Beasts" on Nigeria Soil.
