Yesterday, President Obama signed an executive order to establish the National Strategic Computing Initiative, intended to advance American research efforts that require high-capacity computing (HCC). The main thrust of the program, according to a blog post from the White House, would be to create the world's fastest supercomputer, which would be 20 times faster than today's fastest supercomputer, China's Tianhe-2. The machine would be called an exascale computer--capable of making a billion billion—or one exaflop—calculations per second.
