other tech: Supercomputer communication at 25 Gbps

NEC’s new technology has achieved a transmission speed of 25 gigabits per second, 40 times faster than the Earth Simulator, the fastest supercomputer at present in Japan, which has a transmission speed of 0.5 gigabits per second The technology uses a vertical-cavity surface-emitting laser capable of huge transmissions of data between a central processing unit and a memory device. NEC’s new technology surpassed the previous transmission speed record of 14 gigabits per second achieved last year by a researchers’ group developing a next-generation supercomputing system for the U.S. Department of Defense.
