Two 20-petaflop systems planned for 2012, but China’s Tianhe-1A to rank No.1 on Top500 list this year.

ORNL-Comp-CourtyardThe U.S. is building two 20-petaflop supercomputers, many times more powerful than anything operating today, including China’s new supercomputer, the Tianhe-1A, which is expected to be officially crowned next week as the world’s fastest system.

Oak Ridge National Laboratory, home for what has been the world’s most powerful system, the Jaguar, a 1.75-petaflop system, versus Tianhe-1A’s 2.5 petaflops, is building a 20-petaflop system that will include accelerators.

That system will be ready in 2012, James Hack, director of the National Center for Computational Sciences at Oak Ridge, told Computerworld. No other details about the system are being offered.

Another 20-petaflop system is being built for the Lawrence Livermore National Laboratory by IBM. That system has already been announced and is expected to arrive at the lab in late 2011 and be in production in 2012.
