Advanced Scientific Computing Research

The Advanced Scientific Computing Research (ASCR) program leads the nation and the world in supercomputing, high-end computational science, and advanced networking for science.
Maintaining U.S. leadership requires specialized computer scientists and applied mathematicians who know how to develop supercomputing methods to harness supercomputers to solve real world problems today and develop the technology of the future. Supercomputers push the edge of what is possible for US science and innovation—enabling scientists and engineers to explore systems too large, too complex, too dangerous, too small, or too fleeting to do in the real world. From atoms to astrophysics understanding these complex systems delivers new materials, new drugs, more efficient engines and turbines, better weather forecasts, and other technologies to maintain U.S. competitiveness in a wide array of industries.
We support U.S. research at hundreds of institutions and deploy open-access supercomputing and network facilities at our National Laboratories. Our supercomputers are the world’s most powerful and our high-speed network is specially built for moving enormous scientific data, at light speed. From artificial intelligence to quantum computing, our vibrant research community keeps the U.S. ahead in a rapidly evolving high-tech field and impacted industries. Through strong partnerships between scientists, applied mathematicians and computer scientists, we maintain U.S. leadership in science, technology, and innovation.

Introducing Summit

The biggest problems in science require supercomputers of unprecedented capability. That’s why the US Department of Energy’s Oak Ridge National Laboratory (ORNL) launched Summit, the world's fastest supercomputer. Summit is providing scientists with incredible computing power to solve challenges in energy, artificial intelligence, human health, and other research areas, that were simply out of reach until now. These discoveries will help shape our understanding of the universe, bolster US economic competitiveness, and contribute to a better future.
