National Center for Computational Sciences. It is a premier United States Department of Energy facility for open science, located at Oak Ridge National Laboratory in Tennessee. The center operates some of the world's most powerful supercomputers for computational science and artificial intelligence research. Its mission is to accelerate scientific discovery and engineering breakthroughs across a wide range of disciplines.

History

The center's origins trace to the 1992 establishment of the Center for Computational Sciences at Oak Ridge National Laboratory, which was created to advance high-performance computing. A major milestone was reached in 2004 when leadership of the DOE Leadership Computing Facility was awarded to the laboratory, formally creating the center as a national user facility. This was followed by the deployment of pioneering systems like Jaguar, which in 2009 became the first petaflop-scale system for open science. Subsequent decades saw the center maintain its position at the forefront with machines such as Titan and the Frontier system, which in 2022 was crowned the world's fastest on the TOP500 list.

Mission and objectives

The primary mission is to provide unparalleled computational resources to the scientific community to solve challenges of national and global importance. Key objectives include advancing the capabilities of exascale computing, supporting the DOE Office of Science mission, and integrating artificial intelligence with simulation. The center aims to foster a robust ecosystem of software, applications, and data analytics to maximize the impact of its high-performance computing systems. It also focuses on workforce development and training the next generation of computational scientists.

Major facilities and resources

The center's flagship facility is the Oak Ridge Leadership Computing Facility, which houses the exascale supercomputer Frontier. Other significant historical systems operated include Summit, Titan, and Jaguar. The center also manages the Everest visualization and data analytics system and extensive high-performance data storage infrastructure. These resources are accessible to researchers worldwide through competitive peer-reviewed proposals under the Innovative and Novel Computational Impact on Theory and Experiment program.

Key research areas and projects

Research spans fundamental and applied science, including computational physics, climate modeling, materials science, and bioinformatics. Major projects include simulations for the ITER fusion experiment, large-scale genomics analysis for the Department of Energy's Joint Genome Institute, and cosmological simulations like those for the Dark Energy Spectroscopic Instrument. The center also hosts the Exascale Computing Project, developing applications for fields such as nuclear energy, combustion, and quantum chromodynamics. Artificial intelligence research for scientific discovery is a rapidly growing focus area.

Organizational structure and leadership

The center is a directorate within Oak Ridge National Laboratory, which is managed by UT-Battelle for the United States Department of Energy. It is led by a director, a position held by Dr. Gina Tourassi. The organization comprises divisions focused on operations, science, and technology, including teams for system administration, user support, application performance, and advanced technology. Key advisory input comes from external groups like the Oak Ridge National Laboratory's Scientific Advisory Committee and the DOE Advanced Scientific Computing Advisory Committee.

Collaborations and partnerships

The center maintains deep collaborations with other DOE National Laboratories, including Argonne National Laboratory and Lawrence Berkeley National Laboratory. It partners with leading academic institutions through the Compute and Data Environment for Science consortium and the Exascale Computing Project. International partnerships include work with facilities like the Max Planck Society in Germany and RIKEN in Japan. The center also works closely with industry partners such as Hewlett Packard Enterprise, AMD, and NVIDIA on system development and technology testing.
