Unlocking Innovation: The Impact of DOE’s Exascale Supercomputers on Scientific Research
Supercomputers help scientists perform research that would be impossible otherwise. They enable simulations of large, complex, or quick phenomena that cannot be easily studied through experiments or observations.
The Department of Energy (DOE) provides supercomputing facilities at its national laboratories for both industry and academic researchers. This accessibility ensures that public investments yield the most benefit for American citizens.
Currently, DOE has three exascale computers: Frontier at the Oak Ridge Leadership Computing Facility, Aurora at the Argonne Leadership Computing Facility, and El Capitan at Lawrence Livermore National Laboratory. The Office of Science oversees user facilities for Frontier and Aurora. Frontier became operational in 2022, while Aurora will start in 2025.
El Capitan is the most powerful supercomputer globally and is dedicated to national security. This advancement in high-performance computing boosts the National Nuclear Security Administration’s (NNSA) ability to maintain the safety and reliability of America’s nuclear weapons without explosive testing.
These supercomputers can perform one quintillion floating point operations per second. To put this in perspective, it would take the entire global population five years of continuous simple math to match the calculations an exascale computer can perform in one second. El Capitan’s performance is 20 times greater than its predecessor, enabling it to create detailed 3D simulations that previously required weeks in only hours.
