computing (HPC) infrastructure, the division also hosts the <a href="https://www.olcf.ornl.gov/"><strong>Oak Ridge Leadership Computing Facility</strong></a> (OLCF), a Department of Energy Office of Science User Facility. The OLCF is home to the HPE Cray EX Frontier, which debuted in 2022 as the first supercomputer to break the exascale barrier and the fastest computer in the world. With a peak performance of 1.5 EF, Frontier is capable of over 1 quintillion calculations per second. </p><p>Each year the OLCF provides over 36 million hours of computer time to scientists and engineers who use Frontier and the OLCF's other compute resources to work on some of the most important scientific challenges of our day. The power of exascale will open new doors of discovery in climate, medicine, materials, energy, and beyond. </p></div> </div> </div> </div> </div> </div> <div class="paragraph-container"> <div
