The U.S. government was at the forefront of the race to petascale computing–that’s a quadrillion calculations per second for those of you counting–with computers like Los Alamos National Lab’s Roadrunner and Oak Ridge National Lab’s Jaguar, and Congress has now thrown its weight behind reaching the next plateau, exascale computing.
Last week, House and Senate conferees agreed on full funding for the Department of Energy’s effort to move toward exascale computing by providing $442 million for advanced scientific computing research, $126 million of which will go toward exascale computing, according to the president’s budget proposal.
Exascale computing would represent one thousand times the computing capacity of petaflop computers, which themselves remain extremely rare–only 14 supercomputers made the grade as of the November 2011 list of the world’s top 500 supercomputers. It took a dozen years to move from terascale to petascale, and researchers see the movement to exascale as a long-term goal as well.
