The team’s findings will provide a better understanding of seismic hazards in the Golden State. Building…
PI: Mark Taylor, Sandia National Laboratories In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That meant rethinking, reinventing, and optimizing dozens of scientific applications and software…
On the beach, ocean waves provide soothing white noise. But in scientific laboratories, they play a key role in weather forecasting and climate research. Along with the atmosphere, the ocean is typically one of the largest and most computationally demanding components of Earth system models like the Department of Energy’s Energy Exascale…
The world’s first exascale supercomputer will help scientists peer into the future of global climate change and open a window into weather patterns that could affect the world a generation from now. The research team used Frontier, the 1.14-exaflop HPE Cray EX supercomputer at the Department of Energy’s Oak Ridge…
A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory looks at some of the influences that could be driving the increasingly severe weather over Pakistan. Published in npj Climate and Atmospheric Science, the study analyzed over 40 years of data and found that natural climate…
As extreme weather devastates communities worldwide, scientists are using modeling and simulation to understand how climate change impacts the frequency and intensity of these events. Although long-term climate projections and models are important, they are less helpful for short-term prediction of extreme weather that may rapidly displace thousands of people…
Simulations performed on the Summit supercomputer at the Department of Energy’s Oak Ridge National Laboratory revealed new insights into the role of turbulence in mixing fluids and could open new possibilities for projecting climate change and studying fluid dynamics. The study, published in the Journal of Turbulence, used Summit to…
By Aliyah Kovner, Berkeley Lab Accurately modeling the effects of an earthquake is possible, but it requires intricate physics-based models that can only be run on advanced supercomputers. The data from such models are invaluable for the earthquake research community and engineers seeking to build and retrofit earthquake-resilient homes, businesses,…
Successfully running a simulation program on a supercomputer requires more than just writing code. An application such as a climate model requires libraries, network support, and the correct operating environment. Because of these complex and multilayered requirements, applications are typically customized and built natively on a computing system, making them…
In 2021, supercomputing at the US Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) enabled new scientific breakthroughs amid the global pandemic. From modeling small particles called quarks to simulating turbulence in fusion reactors, the Oak Ridge Leadership Computing Facility's (OLCF's) flagship supercomputer, Summit, continued to provide unprecedented opportunities…
The US Air Force and the US Department of Energy’s Oak Ridge National Laboratory (ORNL) launched a new high-performance weather forecasting computer system that will provide a platform for some of the most advanced weather modeling in the world. Procured and managed by ORNL’s National Center for Computational Sciences, the…

Using the Oak Ridge Leadership Computing Facility’s (OLCF’s) IBM AC922 Summit—the nation’s most powerful supercomputer devoted to open science, located at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL)—a team of researchers from the European Centre for Medium-Range Weather Forecasts (ECMWF) and ORNL achieved a computational first:…
Each year, anywhere from a few hundred to tens of thousands of deaths are attributed to the catastrophic effects of major earthquakes. Apart from ground shaking, earthquake hazards include landslides, dam ruptures, flooding, and worse—if the sea floor is suddenly displaced during an earthquake, it can trigger a deadly tsunami.…
