IBM manufactures lightbased 'nanophotonic' chips to let the terrabytes flow

IBM's taken a large step toward computer chips that use photons instead of electrons by manufacturing the first 90nm silicon-based optical processing modules. It did so using the CMOS nanophotonics technology we first saw back in 2010, creating tranceivers capable of 25Gbps transfer speeds. By multiplexing a large number of those streams to a single fibre, "terrabytes of data" per second could flow between distant computer systems," according to IBM. The 90 nanometer light circuits should allow data-hungry servers or supercomputers to scale up rapidly in speed "for the next decade, and at the desired low cost," according to the researchers. It's now primed for commercial development, meaning we could see an end to bottlenecks in systems "a few centimeters or a few kilometers" apart from each other. Check the PR for the detailed technical skinny.

IBM: ‘We must build an Exascale computer before 2024’ (video)

ASTRON has enlisted the help of IBM to lead a five-year, $43 million project to develop and build a supercomputer for the new Square Kilometer Array. The SKA is a $2.1 billion initiative to construct the world's largest radio telescope across a 3,000km strip of Australia or South Africa. It's hoped to be around 50 times as powerful as the dishes we currently point heavenward and will be used to examine the deepest reaches of space to learn more about the formation of the universe. When it goes live in 2024, it'll produce an Exabyte of data each day: twice as much information as there is traffic on the internet in the same period. Of course, no existing computer could handle the job, so Big Blue has a slim 12 years in which to turn nascent technologies like Nanophotonics, 3D chip stacking and phase change memory amongst others into a practical, workable Exascale computer. Its either that, or somehow daisy-chain 100 million PCs with enough power and cooling fans to keep it all working and hope for the best. If you'd like to know more, then head on past the break, although unfortunately it won't count as college credit.
