While our friends Jaguar and Ranger toil to model the Earth's atmosphere, star formation and battery chemistry, other supercomputers are working on classified national security problems. Namely: What happens when a nuclear weapon explodes? Are we sure our nuclear arsenal would actually work, should, God forbid, we decide to use it?
A Japanese supercomputer is now the world’s fastest, unseating the previous record-holder by nearly a factor of four. The K Computer, based at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, can perform 8 petaflops — that’s 8 quadrillion calculations per second.
A new native Chinese supercomputer set to debut this summer might be the most efficient ever built. It won’t be the fastest, but it sips power to perform terascale calculations, and it’s all built in China.
In an effort to test the awesome power of their new super computer, a team of scientists at University of Tsukuba, Japan, have calculated Pi out to 2.5 trillion decimal places, more than doubling the previous record.

In 2005, IBM's $2-million BlueGene supercomputer took 80 minutes to process the same data that eight million cerebral-cortex neurons—a fraction of the brain's total—handle in one second. Now bioengineer Kwabena Boahen of Stanford University has built a microchip that could help computers catch up.
Sandia and Oak Ridge national labs aim to bust the million trillion calculations-per-second barrier

Time was, a teraflop (that's one trillion, or 10^12 floating point operations per second) was just a dream. But the supercomputer ASCI Red nabbed that prize in 1996. Since then, it's been the grueling, relentless march to a petaflop--that's 10^15 flops for those keeping count--a goal achieved by the Riken MDGrape-3 computer in 2006 (some dispute this claim, as the machine is so specialized it can't properly run the benchmark software. For them, we present the latest iteration of IBM's Blue Gene/P, which is purportedly capable of a petaflop as well).
The world's fastest supercomputer is about to get even faster. Can anyone outdo Blue Gene/L?

The quest to build the world´s most potent supercomputer is like a never-ending Olympic event, with the pride of entire nations at stake. This summer, the U.S. will tighten its grip on the gold when engineers at the Department of Energy´s Lawrence Livermore National Laboratory boost the speed of IBM´s reigning champion Blue Gene/L to an anticipated 270 teraflops-a floor-shaking 270 trillion calculations per second.
