"These goals have considerable support in Congress. Last November a bipartisan group of 24 senators sent a letter to President Obama urging him to approve continued funding through 2013 for the Department of Energy’s exascale computing initiative (the NSA’s budget requests are classified). They cited the necessity to keep up with and surpass China and Japan. “The race is on to develop exascale computing capabilities,” the senators noted. The reason was clear: By late 2011 the Jaguar (now with a peak speed of 2.33 petaflops) ranked third behind Japan’s “K Computer,” with an impressive 10.51 petaflops, and the Chinese Tianhe-1A system, with 2.57 petaflops."
The latest data from http://bitcoinwatch.com/ gives the current processing power working just Bitcoin hashs at 185,509.82 PetaFLOPS with more processing power added daily.
