Welcome to The
Exascale Computing Project

The quest to develop a capable exascale ecosystem is a monumental effort that requires the collaboration of government, academia and industry.


Achieving exascale will have profound effects on the American people and the world—improving the nation’s economic competitiveness, advancing scientific discovery, and strengthening our national security.


The Exascale Computing Project (ECP) was established with the goals of maximizing the benefits of high-performance computing (HPC) for the United States and accelerating the development of a capable exascale computing ecosystem.

Exascale refers to computing systems at least 50 times faster than the nation’s most powerful supercomputers in use today.

The ECP is a collaborative effort of two U.S. Department of Energy organizations – the Office of Science (DOE-SC) and the National Nuclear Security Administration (NNSA).

ECP is chartered with accelerating delivery of a capable exascale computing ecosystem to provide breakthrough modeling and simulation solutions to address the most critical challenges in scientific discovery, energy assurance, economic competitiveness, and national security.

This role goes far beyond the limited scope of a physical computing system. ECP’s work encompasses the development of an entire exascale ecosystem: applications, system software, hardware technologies and architectures, along with critical workforce development.

“The Exascale Computing Project offers a rare opportunity to advance all elements of the HPC ecosystem in unison. Co-design and integration of hardware, software, applications and platforms, a strategic imperative of the ECP, is essential to deploying exascale-class systems that will meet the future requirements of the scientific communities these systems will serve.” – Paul Messina, ECP Director
