Computing and Computational Sciences


ORNL is a premier source of computational science research. 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. 

ORNL is using computing to tackle national challenges

  • Sustainable energy solutions
  • Safe nuclear energy systems
  • Advanced materials
  • Sustainable transportation
  • Climate change
  • Detailed knowledge of the atomic-level structure and dynamics of materials
