Who We Are

Oak Ridge National Laboratory (ORNL) is one of six national laboratories leading in the Department of Energy’s Exascale Computing Project, which was chartered with accelerating delivery of a capable exascale computing ecosystem to provide breakthrough modeling and simulation solutions to address the most critical challenges in scientific discovery, energy assurance, economic competitiveness, and national security.


ORNL is a premier source of computing and computational science research for the nation, with a long and successful history of delivering breakthrough science and powerful tools for discovery. It is also home to the Oak Ridge Leadership Computing Facility, providing the open scientific community access to America’s fastest, most powerful supercomputer. We are addressing some of the biggest challenges and problems of our time, and our supercomputers have decreased time to solution, increased the complexity of models, and improved realism of simulations of subjects ranging from development of advanced materials, to cleaner combustion of fuels, to understanding climate dynamics.
