Powering Discovery for Years to Come

Oak Ridge National Laboratory explores fundamental scientific challenges in energy and security ― and delivers transformative solutions to them. Their work may start in the theoretical but it ends in the marketplace in the products and services that make our world safer, cleaner, and healthier.

Now the lab enters a new era of discovery and innovation with Frontier ― their first exascale supercomputer. Able to perform one quintillion operations per second, Frontier will be built on Cray’s revolutionary new Shasta™ supercomputing platform.

Coming in 2021, this landmark system will help lead the way into the exascale era. It’s an era where we’re not only transforming how we compute, we’re transforming what we can solve, discover, and achieve.

Solving Big Problems

Oak Ridge National Laboratory (ORNL) is the U.S. Department of Energy’s (DOE) largest multiprogram science and energy laboratory. Its scientific and technical capabilities span basic to applied research and an exceptionally wide range of R&D problems from nuclear physics to advanced energy systems. In service of solving the DOE’s fundamental research challenges, ORNL puts emphasis on combining scientific insights and applied systems to deliver practical solutions to the marketplace. Its discoveries create new industries, provided jobs, and support the DOE’s in ensuring the nation’s security and prosperity.

The Oak Ridge Leadership Computing Facility (OLCF) is Oak Ridge National Laboratory’s supercomputing program. OLCF provides world-class HPC resources and scientific computing expertise to researchers working on the world’s most difficult scientific problems in disciplines from biology to seismology. It helps scientists and engineers deliver practical breakthroughs and new knowledge in climate, materials, nuclear science, and more. This U.S. Department of Energy Office of Science User Facility will be home to Frontier.


Understand the speed and size of an exascale supercomputer

Oak Ridge National Laboratory’s Frontier supercomputer will be able to perform 1.5 quintillion operations per second. But what does that number even mean? Our infographic helps illustrate the massive speed and size of an exascale system.

Why Exascale Is a New Era

The supercomputing industry has hit major speed and scale milestones before. But exascale is different. It’s different because questions are changing – and so must the workloads tasked with answering them.

Traditional modeling and simulation are converging with artificial intelligence, analytics, and IoT to create single workflows operating at unprecedented scale and in real-time. It demands a complete rethinking of how we design compute infrastructure. And it’s an effort whose success depends on collaboration with visionaries like ORNL. Their Frontier supercomputer will lead the way into the exascale era, bringing more capabilities, discoveries and efficiencies to a larger number of people than ever before.

Cray’s Shasta supercomputing architecture and Slingshot interconnect form the foundation of Frontier’s exascale capabilities.

Shasta Supercomputer

Cray’s new supercomputer, code-named Shasta, is an entirely new design and will underpin the next era of supercomputing. The system is characterized by exascale performance capability, new datacentric workloads, and an explosion of processor and accelerator architectures. Shasta incorporates next-generation Cray system software to enable modularity and extensibility, supports unparalleled flexibility in processing choice, and scales seamlessly.
