Exascale Computing Project (ECP) was a Department of Energy initiative managed by the Office of Advanced Scientific Computing Research that united over 2,800 researchers across the United States to deliver the nation’s first capable exascale computing ecosystem, concluding in 2024 after deploying systems like Frontier, Aurora, and El Capitan, which collectively exceed 3 exaflops and support over 50 mission-critical applications as of 2025. Launched in 2016 with a $1.8 billion budget, ECP—a joint effort of DOE’s Office of Science and National Nuclear Security Administration—developed an integrated stack of applications, software, and hardware, enhancing energy assurance, scientific discovery, and national security, with post-Hurricane Helene resilience efforts in 2025 leveraging its legacy tools like the Extreme-scale Scientific Software Stack (E4S) across DOE facilities.

Goals
- Deliver an exascale ecosystem for breakthrough modeling and simulation.Expansion depth limit exceeded
- Accelerate scientific and national security solutions via high-performance computing.
- Advance software and hardware integration for DOE mission-critical needs.
Organization
The Exascale Computing Project was sponsored by the Office of Advanced Scientific Computing Research (ASCR) within the Department of Energy, headquartered in Washington, D.C., with leadership from six DOE labs: Argonne, Lawrence Berkeley, Lawrence Livermore, Los Alamos, Oak Ridge, and Sandia.Expansion depth limit exceeded Funding came from Congressional appropriations, supporting over 2,800 collaborators across 17 DOE labs, academia, and industry, managed by a leadership team including Project Director Doug Kothe and overseen by ASCR and NNSA.
The leader at the Department of Energy level was the Associate Director of Science for ASCR, Ceren Susut (as of February 22, 2025), with ECP led by Doug Kothe until its 2024 conclusion.
History
The Exascale Computing Project was established in 2016 under the Energy Policy Act of 2005, which bolstered DOE’s advanced computing research, as part of the National Strategic Computing Initiative.Expansion depth limit exceeded It progressed from 2016 to 2024, deploying Frontier (2022, 1.1 exaflops), Aurora (2023), and El Capitan (2024), concluding technical work in December 2023 after supporting over 50 projects, with 2025 efforts transitioning its E4S and resilience tools post-Hurricane Helene to ongoing DOE missions.
Funding
Initial funding in 2016 was $1.8 billion from Congressional appropriations.Expansion depth limit exceeded Funding spanned 2016-2024, totaling $1.8 billion, supporting over 2,800 researchers and 50+ projects across applications, software, and hardware, concluding in 2024 with no further appropriations, though its legacy sustains 2025 efforts like resilience modeling.
Implementation
The program was implemented through co-design of applications, software (e.g., E4S), and hardware, deploying exascale systems at DOE facilities like Oak Ridge, Argonne, and Lawrence Livermore.Expansion depth limit exceeded It ran from 2016-2024, enhancing over 300 million acres of habitat modeling via partnerships, with 2025 efforts leveraging its tools post-Helene for energy and scientific resilience across all 50 states.
