Oak Ridge National Laboratory – Oak Ridge Leadership Computing Facility

Description

Building on its 25-year history as a global leader in high-performance parallel computing, the Oak Ridge Leadership Computing Facility (OLCF) is now home to the world’s fastest supercomputer and the first exascale computer, Frontier. Exascale is an unprecedented level of computing performance of a quintillion calculations per second. The Frontier system leverages ORNL’s extensive expertise in accelerated computing and will enable scientists to develop critically needed technologies for the country’s energy, economic and national security, helping researchers address problems of national importance that were impossible to solve just five years ago. Using OLCF supercomputers, scientists can develop a wide range of numerical simulations applicable to MRE problems, using either off-the-shelf Computational Fluid Dynamic software or developing custom scalable codes. Relevant simulations include turbine hydrodynamics and design optimization, fluid-structure interaction modeling, smooth particle hydrodynamics, environmental modeling, and mooring dynamics simulation.

The Oak Ridge National Laboratory (ORNL) hosts three petascale computing facilities: the Oak Ridge Leadership Computing Facility (OLCF), managed for DOE; the National Institute for Computational Sciences (NICS), operated for the National Science Foundation (NSF); and the National Climate-Computing Research Center (NCRC), formed as collaboration between ORNL and the National Oceanographic and Atmospheric Administration (NOAA) to explore a variety of research topics in climate sciences. Each facility has an experienced operational and engineering staff comprised of groups in high-performance computing (HPC) operations, technology integration, user services, scientific computing, advanced data and workflows, and application performance tools. Front-line computer facility staff provide 24×7 operation of the centers and immediate problem resolution.
