India enters supercomputing race

50°
353w ago - A computer system designed in India has made it into a top ten of the world's fastest supercomputers.

Computer giant IBM continues to dominate the list - which is compiled twice a year - with a total of 232 out of the top 500 supercomputers.

Its Blue Gene/L supercomputer - used to ensure the US nuclear weapons stockpile remains safe and reliable - comes out at number one.

The Indian system - known as EKA - made it into fourth place.

The world's fastest supercomputer - BlueGene/L - has been significantly upgraded in the last six months.

It can now deliver a sustained performance of 478 trillion calculations per second (478 teraflops), nearly three times faster than any other machine on the list.

Petaflop barrier

Second place went to another IBM system - a newer version of BlueGene/L known as BlueGene/P. The system, introduced this June is the first in a batch of IBM machines designed to operate at a petaflop and beyond.

Breaking the petaflop barrier - the ability to process 1,000 trillion calculations every second - has long been a key milestone in supercomputing and would allow highly detailed simulations.

For example in earthquake simulations it could show building-by-building movements of regions in earthquake zones,...
 

PixelJunk Racers Review for PS3

50°
360w ago - PixelJunk Racers is a neat little game that takes the basic concepts of slot car racing and applies them to a multitude of minigame-like events that you can play alone or against friends. There are a good number of different events, though the addition of a few more tracks and online multiplayer would have made it a much longer-lasting collection.

The controls in Racers are simple. You can use either the D pad or the analog stick to change lanes, and the L2 or R2 triggers can be used to control how fast you're moving. You don't have direct steering control, and so you can swap between lanes only one at a time. This control scheme is applied across 10 different tracks and 32 different game types, which gives you a lot of different potential combinations. But that doesn't prevent the game's solo tournament mode, which gradually unlocks tracks and game types as you play, from feeling monotonous for sticking to the same handful of tracks early on.

Some events are basic races to the finish line. Others include stuff like "the munchies," which is accompanied by this helpful life lesson: "Eat cars to stay alive for as long as possible!" Still others have you blowing up your car like a balloon to charge it with forward movement; dodging cars until you pass enough to turn into a fireball, at which point you have...
