Road to Exascale Computers
SAN JOSE, Calif., Oct. 16, 2009 -- Exascale computers, which would be 1000 times more powerful than today's fastest supercomputers, will need to have optics playing a bigger role, said Jeffrey Kash of IBM Research during a presentation at Frontiers in Optics 2009.
Kash, who said he was presenting his own views and not those of IBM Research, said that VCSEL-based optics have displaced electric cables today in supercomputers, but with power, density and cost requirements increasing exponentially as the systems get powerful,...
