Three national laboratories, including Oak Ridge National Laboratory, are building new computer systems that could be many times more powerful than today’s top supercomputers.

The new machines are exascale systems. None have been delivered yet, but the planning for them started more than a year ago and the new high-performance systems could be delivered to the three laboratories in the next several years. Planning for the exascale computers was under way even before the world’s most powerful supercomputer, a petaflop system called Summit at ORNL, was unveiled in June 2018.

Exascale computers could be 50 to 100 more powerful than today’s petaflop computers, according to the U.S. Department of Energy. Besides ORNL, they could be located at Argonne National Laboratory southwest of Chicago and Lawrence Livermore National Laboratory east of San Francisco. The first system is expected at Argonne, followed by a second system at ORNL.

Tennessine is among the names proposed for four new elements. If approved, the name would recognize the contributions of Tennessee research centers—Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee—in the discovery of one of four new superheavy elements: 113, 115, 117, and 118.

Tennessine (Ts) is proposed for element 117.

The discovery of the four new elements was announced in January, and Oak Ridge National Laboratory played a role in discovering two of them. The elements have been added to the periodic table, filling the seventh row, or period.

Twenty-two milligrams of a very pure synthetic material produced at ORNL were used in the discovery of two of the new chemical elements. [Read more…]

Laboratory directors from Sandia National Laboratory, Lawrence Livermore National Laboratory, and Los Alamos National Laboratory recently visited the Y-12 National Security Complex in Oak Ridge.

The group toured facilities at the site, including production buildings and Y-12’s Nuclear Detection and Sensor Testing Center, a press release said.

Pictured above are employees at Y-12; lab directors from SNL, LLNL, and LANL; and the National Nuclear Security Administration Production Office.
