Computing Resources
World-Class Computing
The HPC4EI Program uses world class computing power across nine U.S. Department of Energy laboratories. Combined, the DOE systems, which include 5 of the top 20 systems as ranked by TOP500 in June 2021, mark some of the most powerful computing resources in the world.


In addition, through the national laboratories, DOE actively infuses and maintains a comprehensive ecosystem of high performance computing assets and the industry leading scientists and engineers capable of leveraging their power.
Each project awarded through the HPC4Manufacturing and HPC4Materials pillars is matched with a specific super computing system that best meets their needs. Through the overarching HPC4EI program, we are leveraging this family of DOE systems to bring world class computing power to solve some of the most challenging problems facing US industry.
