Over at Computerworld, Patrick Thibodeau writes that President Barack Obama’s federal budget plan released this week calls for increases in federal R&D spending, but does not set a goal for building Exascale systems.
Every decade, compute power has double in alignment with Moore’s Law. The power of supercomputing has followed a similar path. Following that target, an exascale system might have been possible in the 2018 timeframe. The petaflop barrier was broken in 2008. Exascale development, however, poses unique challenges because of the enormous amount power such a system would likely need. That challenge is driving a re-thinking of all aspects of systems development. But because of funding uncertainty, federal officials have said that an exascale system may not be developed in the U.S. until 2022.
