Edit Program: Oak Ridge Leadership Computing Facility

Free text:

'''Oak Ridge Leadership Computing Facility''' (OLCF) is a Department of Energy program operated by Oak Ridge National Laboratory (ORNL) to provide world-class high-performance computing (HPC) resources for groundbreaking scientific research. The facility delivers cutting-edge supercomputers like Summit and Frontier—the latter being the world’s first exascale system operational since 2022—to researchers globally, addressing complex challenges in energy, biology, and materials science, while advancing computational science through HPC and artificial intelligence (AI) tools for open science. Established as part of DOE’s Leadership Computing Facility initiative, OLCF has set benchmarks in computational power, supporting discoveries from climate modeling to quantum physics. {{Official URL (simple)|url=https://www.olcf.ornl.gov}} ==Goals== * Provide exascale computing (10^18 calculations per second) to accelerate scientific discovery across disciplines. * Enable open access to HPC resources, targeting support for thousands of peer-reviewed projects annually. * Drive innovation in HPC and AI, with success measured by system performance rankings and research impact. ==Organization== The Oak Ridge Leadership Computing Facility is managed by Oak Ridge National Laboratory, a DOE Office of Science laboratory, with funding from DOE appropriations under the Advanced Scientific Computing Research (ASCR) program. It operates supercomputers like Titan, Summit, and Frontier, supported by a team of computational experts. Governance involves DOE oversight, with user access allocated through competitive programs like INCITE. Industry partners, such as IBM, NVIDIA, and HPE, collaborate on system design and deployment. The leader of the program holds the title of OLCF Director, currently Gina Tourassi as of 2025. ==History== The OLCF was launched in 2004, with significant funding authorized by the [[Energy and Water Development Appropriations Act of 2005]], establishing it alongside Argonne as a DOE Leadership Computing Facility to elevate U.S. computational science. It began with Jaguar (2005), scaled to petascale with Titan (2012), and achieved exascale with Frontier in 2022, topping the TOP500 list as the world’s fastest supercomputer. Milestones include Summit’s 2018 deployment via CORAL and Frontier’s role in exascale breakthroughs like genomic simulations. The facility plans ongoing upgrades to maintain HPC leadership. ==Funding== The OLCF received an initial $150 million for early systems like Jaguar, funded through DOE appropriations starting in 2004.<ref>{{cite web |url=https://www.olcf.ornl.gov/about-olcf/ |title=About OLCF |publisher=Oak Ridge Leadership Computing Facility}}</ref> Funding continues annually with no end date, with major investments like Frontier’s development costing over $600 million through DOE and vendor contracts with HPE and AMD. Additional funding supports operations, user programs, and future system enhancements. ==Implementation== OLCF implements its mission by deploying and maintaining supercomputers, providing user support, and managing access via programs like INCITE and Director’s Discretionary awards. Implementation includes phased upgrades—Jaguar (2005), Titan (2012), Summit (2018), and Frontier (2022)—using co-design with vendors for performance and efficiency. The program has no defined end date, focusing on sustained HPC advancements and adapting to emerging scientific needs. ==Related== * [[Argonne Leadership Computing Facility]] * [[Collaboration of Oak Ridge, Argonne, and Livermore]] * [[Advanced Scientific Computing Research]] ==External links== * https://www.olcf.ornl.gov * https://www.energy.gov/science/leadership-computing-facilities * [[wikipedia:Oak Ridge Leadership Computing Facility]] ===Social media=== * https://twitter.com/OLCFGOV ==References== <references /> [[Category:Programs and initiatives]] [[Category:Programs]] [[Category:Department of Energy]]
