The Oak Ridge Leadership Computing Facility (OLCF) was established at Oak Ridge National Laboratory to accelerate scientific discovery and engineering progress by providing world-leading computational performance and advanced data infrastructure. The OLCF is home to the nation’s two fastest supercomputers: Summit and Frontier.

The IBM AC922 Summit supercomputer, the second fastest in the United States. Summit can perform 200 quadrillion calculations per second, or 200 petaflops. Researchers use Summit to investigate otherwise inaccessible global problems: from designing new materials, energy sources, and treatments for disease to modeling complex phenomenon related to weather or space to gaining new insights by analyzing gargantuan amounts of data.

In 2022, the NCCS and the OLCF debuted the HPE-Cray EX Frontier supercomputer as the world’s fastest and the first to break the exascale barrier with 1.1. exaflops. Frontier will enable scientists to discover new patterns in patient data for precision medicine, uncover the origins of disease, shed light on new properties of materials, and advance research in high-energy physics.
