The Department of Energy has launched a large high performance computing collaboration focused on climalte modeling - Accelerated Climate Modeling For Energy (pdf)
The Accelerated Climate Modeling for Energy (ACME) project is a newly launched project sponsored by the Earth System Modeling program within DOE’s Office of Biological and Environmental Research. ACME is an unprecedented collaboration among eight national laboratories, the National Center for Atmospheric Research, four academic institutions, and one private-sector company to develop and apply the most complete, leading-edge climate and Earth system models to the most challenging and demanding climate- change research imperatives. It is the only major national modeling project designed to address U.S. Department of Energy (DOE) mission needs and efficiently utilize DOE Leadership Computing resources now and in the future. While the project’s capabilities will address the critical science questions articulated in this plan, its modeling system and related capabilities also can be flexibly applied by the DOE research community to address mission-specific climate change applications, such as those identified in the report, U.S. Energy Sector Vulnerabilities to Climate Change and Extreme Weather.
The remainder of this section provides an overview of the ACME project strategy. Section 2 articulates our science priorities and the short- and long-range plans to address them. Section 3 provides more detail on the computational research challenges the project faces as we move Earth system modeling onto the new disruptive architectures. Our scientific metrics of model performance are described in section 4. Section 5 describes the initial construction of the software engineering and workflow infrastructure needed to support the ACME project. Finally, section 6 addresses the changes in the ACME management structure and function that resulted from the peer review.
1.1 The ACME Vision
The Accelerated Climate Modeling for Energy Project is an ongoing, state-of-the-science Earth system modeling, simulation, and prediction project that optimizes the use of DOE laboratory resources to meet the science needs of the nation and the mission needs of DOE. In this context, “laboratory resources” include the people, programs, and facilities, current and future. They collectively represent a unique combination of scientific and engineering expertise as well as leadership computing and information technologies required to construct, maintain, and advance an Earth system modeling capability that is needed by the country and DOE. A major motivation for the ACME project is the coming paradigm shift in computing architectures and their related programming models as capability moves into the exascale era. DOE, through its science programs and early adoption of new computing architectures, traditionally leads many scientific communities, including climate and Earth system simulation, through these disruptive changes in computing.
1.2 The ACME Ten-Year Goal
Over the next 10 years, the ACME project will assert and maintain an international scientific leadership position in the development of Earth system and climate models at the leading edge of scientific knowledge and computational capabilities. With its collaborators, it will demonstrate its leadership by using these models to achieve the goal of designing, executing, and analyzing climate and Earth system simulations that address the most critical scientific questions for the nation and DOE.
