Office of Advanced Scientific Computing Research
The Office of Advanced Scientific Computing Research provides high-performance computing support and foundational computational science for national priorities across United States Department of Energy, interfacing with Argonne National Laboratory, Lawrence Berkeley National Laboratory, Oak Ridge National Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories. It advances algorithms, software, and computing facilities used by projects such as Exascale Computing Project, Human Genome Project, ITER, National Ignition Facility, and collaborations with agencies including National Aeronautics and Space Administration, National Institutes of Health, National Science Foundation, Defense Advanced Research Projects Agency, and Department of Defense. The office supports research spanning partnerships with universities such as Massachusetts Institute of Technology, Stanford University, University of Illinois Urbana–Champaign, University of California, Berkeley, and Princeton University.
The office funds foundational activities in computational mathematics, extreme-scale software, and high-performance hardware procurement for programs like Exascale Computing Project, Advanced Scientific Computing Research (ASCR) Leadership Computing Facilities, and initiatives that serve users from Fermi National Accelerator Laboratory, Brookhaven National Laboratory, National Renewable Energy Laboratory, and Pacific Northwest National Laboratory. It coordinates with standards bodies and initiatives such as OpenMP, Message Passing Interface, IEEE, US Ignite, and partners in industry including IBM, Intel, NVIDIA, Cray Inc., and AMD.
The office traces roots to computational programs initiated within United States Department of Energy laboratories during the post–Cold War era connecting efforts at Argonne National Laboratory and Lawrence Livermore National Laboratory and responding to calls from the High Performance Computing Act of 1991 and the research priorities of Office of Science and Technology Policy. Early programs funded collaborations involving John von Neumann-inspired architectures, influenced by projects at Los Alamos National Laboratory and Sandia National Laboratories and later pivoted toward exascale planning with the Exascale Computing Project and procurement of systems like Frontier (supercomputer), Aurora (supercomputer), and Summit (supercomputer).
The office’s mission emphasizes advancing computational methods, software ecosystems, and computing infrastructure to enable scientific discovery across disciplines represented by Lawrence Livermore National Laboratory, Oak Ridge National Laboratory, Argonne National Laboratory, Los Alamos National Laboratory, and university partners such as California Institute of Technology and Georgia Institute of Technology. Objectives include delivering algorithms for simulation and modeling used in projects like ITER and National Ignition Facility, supporting data-intensive science from collaborations with CERN-adjacent teams and biomedical efforts tied to National Institutes of Health projects, and ensuring resilient hardware roadmaps in partnership with Intel, NVIDIA, AMD, and procurement agencies like National Nuclear Security Administration.
Programs span applied mathematics, computational science, and computer science topics that intersect with work at Massachusetts Institute of Technology, University of California, Davis, Columbia University, Yale University, and University of Michigan. Research areas include high-performance computing architectures exemplified by Cray Inc. designs, numerical linear algebra used in climate models similar to those developed at National Center for Atmospheric Research, scalable I/O and storage advances relevant to Oak Ridge Leadership Computing Facility, uncertainty quantification practiced with collaborators at Sandia National Laboratories, and machine learning techniques applied in partnership with Google DeepMind, Microsoft Research, and IBM Research.
The office operates and funds leadership-class facilities such as Oak Ridge Leadership Computing Facility, Argonne Leadership Computing Facility, and National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory, hosting systems like Frontier (supercomputer), Summit (supercomputer), and planned machines such as Aurora (supercomputer). Facilities provide services to scientific user communities from Fermi National Accelerator Laboratory, Brookhaven National Laboratory, Los Alamos National Laboratory, and external academia, and coordinate data storage strategies with projects like ESnet and archive initiatives inspired by Kepler and Large Hadron Collider data challenges.
The office maintains partnerships with federal agencies including National Science Foundation, National Aeronautics and Space Administration, National Institutes of Health, Defense Advanced Research Projects Agency, and National Institute of Standards and Technology; national laboratories such as Argonne National Laboratory, Oak Ridge National Laboratory, Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, and Sandia National Laboratories; and industry partners like IBM, Intel, NVIDIA, Cray Inc., and AMD. It supports cross-disciplinary teams involving Princeton University, University of California, San Diego, University of Texas at Austin, University of Chicago, and international collaborations with institutions associated with CERN, Rutherford Appleton Laboratory, and Swiss National Supercomputing Centre.
Funding is appropriated through the United States Department of Energy Office of Science budget and allocated via competitive grants, cooperative agreements, and user facility allocations, guided by strategic plans and roadmaps developed with input from panels such as the National Research Council and advisory committees convened with stakeholders from Oak Ridge National Laboratory, Argonne National Laboratory, and partner universities. Administrative oversight involves coordination with offices including Office of Science and Technology Policy and programmatic review cycles that align with federal appropriations processes and directives from United States Congress.
