“DoE NNSA Post-Exascale Computing Strategy“

Abstract

The Advanced Simulation and Computing (ASC) program, in the U.S. Department of Energy (DOE) National Nuclear Security Administration (NNSA), is responsible for providing high-performance simulation capabilities and computational resources for the NNSA Stockpile Stewardship Program. Within recent years, ASC has experienced major disruptive computing architecture changes which cause numerous code performance and portability challenges. Responding to the 2023 National Academy of Science, Engineering, and Medicine’s Post-Exascale report, we will present ASC’s near-term plan that addresses the challenges and recommendations discussed in the report.
Partnering with industry to do hardware/software research and development, field testbeds and prototypes, and procuring high-performance computing platforms – all to keep pace with the technology changes – will continue because they allow the ASC program to anticipate and prepare for future technological disruptions. Sustained, tightly coordinated collaborations with industry partners, U.S. agencies, and international organizations will enable the optimal use of these technologies to meet the NNSA stockpile stewardship requirements.
