President Obama doesn't have much longer in office, but one of his last executive orders while he's in power, is that the United States build the world's fastest supercomputer by 2025.
The National Strategic Computing Initiative has been kicked off to get the US building an Exascale capable machine that would lead the world in the technological arms race. The new system will be developed by various arms of the federal government, and then be boosted up in speed to help research in various topics. One area would be helping NASA "better understand turbulence for aircraft design", reports Engadget.
As it stands, the US is behind both China and Japan when it comes to supercomputer speed. China's Tianhe-2 has been the world's fastest supercomputer for nearly two and a half years now, but with the federal government behind it, and I'm sure a boat load of taxpayers' money, the US will have Skynet online in 2025.
