Exascale Explorers

Since its beginning, Argonne National Laboratory has been at the center of the United States’ effort to provide its scientific communities with leading computing resources. It solidifies that position with the announcement of Aurora, the nation’s first exascale supercomputer.

Coming in 2021, Aurora is a Cray® Shasta™ supercomputer with additional compute and accelerator infrastructure provided by Intel. But what it will do extends far beyond what it is. The most advanced supercomputer ever, Aurora will power scientific and engineering advancements in every field of inquiry beyond anything so far imaginable.

Read the announcement for details on the Aurora system.

It seems fitting that America's first exascale supercomputer, the country's initial entrant in the global exascale race, is a Cray, a name synonymous with the word supercomputer.

—Steve Conway, Hyperion Research Senior Vice President of Research

A Scientific Computing Leader

Argonne National Laboratory (ANL) is a storied science and engineering research center that leads discovery in a wide range of disciplines from high-energy physics and materials science to biology and advanced computer science. The laboratory collaborates with universities, industry, and government agencies on the nation’s largest questions and experiments ― problems too big for any single institution.

The Argonne Leadership Computing Facility at ANL accelerates these major scientific discoveries and engineering breakthroughs by designing and providing world-leading computing facilities in partnership with the computational science community. This U.S. Department of Energy Office of Science User Facility houses the nation’s premier computing resources for open science research and will be home to Aurora.

What Makes Exascale Performance Possible

The U.S. Department of Energy has been building a dominant scientific computing research program for decades. As part of their program, they collaborate with the nation’s leaders in all fields to overcome scientific barriers. The collaboration between the DOE’s Argonne National Laboratory, Cray, and Intel represents a joining of leaders in their respective fields all focused on exascale as their target.

Making Aurora possible took a cooperative effort between industry, government, and academia. Dignitaries from all the organizations involved gathered March 18 to announce and celebrate the achievement.

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.
