Titan, a new supercomputer located at Oak Ridge National Laboratory, has taken over the top spot as the world’s most powerful according to the TOP500 list of the world’s fastest supercomputers. NNSA’s Sequoia supercomputer, housed at Lawrence Livermore National Laboratory, is now ranked as the second fastest supercomputer. Sequoia was previously  ranked as the fastest last June.
This brings the total number of DOE systems in the fastest 20 to five, with: Mira at Argonne National Laboratory, ranked fourth; Cielo, located at Los Alamos National Laboratory and operated jointly by Los Alamos and Sandia National Laboratories, ranked 18th; and Hopper at Lawrence Berkeley National Laboratory, ranked 19th.
“The nation that leads the world in high-performance computing will have an enormous competitive advantage across a broad range of sectors, including national defense, science and medicine, energy production, transmission and distribution, storm weather and climate prediction, finance, commercial product development, and manufacturing,” said U.S. Secretary of Energy Steven Chu. “Titan joins the Department’s top-ranking supercomputers in equipping our nation’s researchers with the tools needed to keep the United States on the cutting edge of innovation.”
