Japan Bests IBM in Supercomputer Stakes
One future hurdle is the silicon chip that is the brain of these machines. Already engineers are reaching the physical limits of how many circuits they can cram onto a slice of silicon, though chip makers are experimenting with new technologies and materials for the next generation of microprocessors.
After nearly four years in development and $9 million spent, the Riken machine is the first ever to accomplish the feat. It's nearly three times swifter than BlueGene/L, the official No. 1 in an industry ranking called the Top 500...
