Two NNSA supercomputers—Trinity and Sequoia—are among the top six systems in the world, according to the 46th edition of the twice-yearly TOP500 list of the most powerful supercomputers released this month. Sequoia has been the world’s third most powerful computer since June 2013, while Trinity is new to the top-ten list this fall in sixth place.
NNSA’s newest champion supercomputer was named after the Trinity Test of 1945—the world’s first nuclear detonation. Since the U.S. no longer conducts underground nuclear testing, Trinity’s primary purpose is to enable NNSA perform full-physics, 3-dimensional simulations to assess the nuclear weapons' performance, as their continued mission to ensure the safety, security and effectiveness of the U.S. nuclear deterrent.
