The Exascale Computing Project (ECP)

The ECP ran from 2016–2024 and was the largest software research, development, and deployment project managed to date by the US Department of Energy (DOE). The $1.8 billion project was a joint effort by the DOE Office of Science and the National Nuclear Security Administration that funded nearly 2,800 multidisciplinary individuals over the lifetime of the project to uplift the high-performance computing community toward capable exascale platforms, software, and application codes. The outcome was the delivery of an exascale computing ecosystem to provide breakthrough solutions that address future challenges in energy assurance, economic competitiveness, healthcare, and scientific discovery, as well as growing security threats. The ECP exascale ecosystem includes DOE mission-critical application codes, the underlying supporting software technologies, and mechanisms for their deployment and integration.

ECP was a grand convergence of advances in modeling and simulation, software tools and libraries, data analytics, machine learning, and artificial intelligence in support of delivering the world’s first capable exascale ecosystem.

The payoff is here: exascale computing is revolutionizing nearly every domain of science.

ECP by the Numbers

Created to develop the nation’s first capable exascale computing ecosystem, this unprecedented DOE research, development, and deployment project has already made a huge impact on computational science:

idea icon2,800 collaborators funded to develop exascale applications, software, and hardware.
planning iconGame-changing results in a broad spectrum of science and engineering application areas.
chip icon2 different GPU architectures now proven to work with exascale environments.
cloud data iconFirst and only open-source scientific software stack developed for scalability and available across all HPC platforms, including cloud computing.

ECP Impact

Mission-critical Applications, an Integrated Software Stack, and Exascale Hardware Technology Advances

Software Stack

The Extreme-scale Scientific Software Stack is the first and only open-source scientific software stack that provides portable high-performance tools and libraries across all GPU and CPU architectures. No other software stack plays a similar role in the high-performance scientific and artificial intelligence ecosystems.

  • Key to transforming the U.S. scientific software infrastructure to utilize modern GPU platforms to accelerate industrial, commercial and scientific advanced computing;
  • Readily available for all high-performance computing platforms and major cloud environments, including AWS and Google Cloud;
  • Robust with most of the commonly used AI libraries and tools and less commonly available AI products that target scientific applications.
