NNSA Completes LLNL Exascale Computing Facility Modernization Project

WASHINGTON, June 9, 2022 — The Department of Energy’s National Nuclear Security Administration today announced the formal completion of construction on the Exascale Computing Facility Modernization project at Lawrence Livermore National Laboratory in Livermore, California. The project enhanced the electrical and mechanical capabilities of the Livermore Computing Center, enabling the facility to power the first NNSA exascale system, called El Capitan, and provide exascale-class computing service (with performance of at least one trillion calculations). per second). ) to LLNL, Los Alamos National Laboratory, and Sandia National Laboratories.

The Exascale Computing Facility modernization project enhances the electrical and mechanical capabilities of the Livermore Computing Center, enabling the facility to provide exascale-class computing service.

On May 5, NNSA approved the formal completion of construction and the beginning of transition to operations – known as Critical Decision-4 under the Department of Energy’s process for planning and executing major construction projects. The project more than doubled the facility’s existing cooling capacity, which can now absorb enough heat to melt 28,000 tons of ice per day. It also upgraded the existing electrical system from 45 megawatts to 85 megawatts, expanding with new transmission lines, switches and substations.

The lab will be cutting a ribbon on June 15 to celebrate the achievement.

“We are delighted that this project has received approval for CD-4. It plays a vital role in supporting NNSA’s goal of bringing more advanced computing capability to the complex. Bringing exascale computing capabilities to the NNSA enterprise from 2023 will aid the country’s efforts in an important, time-critical weapons modernization project and serve as a testament to the country’s commitment to leadership in high-performance computing.” Mike Lang, federal program manager for the Advanced Simulation and Computing program.

The upgrades will enable LLNL to use supercomputers capable of regularly performing the high-fidelity, 3D modeling and simulation tasks needed to meet the increasingly challenging certification requirements of NNSA’s Stockpile Stewardship Program and its mission to to improve the nation’s nuclear deterrent capability.
