High Performance Computing: The Computational Resources behind the Agency’s Environmental Modeling and Visualization
High Performance Computing (HPC) provides the infrastructure, software and technical support for EPA researchers and scientists to run their own compute jobs on EPA HPC machines. This enables quick and easy access to the resources needed for a variety of research, including work on the General Coastal Ecosystem Model (GCEM) and the Community Multiscale Air Quality Model (CMAQ) -- a powerful computational tool used by EPA and states for air quality management.
The main server that provides high-end scientific computing resource for Vis/HPC projects and models is the HPC system Atmos.
Compute time on Atmos is shared by EPA scientists and researchers. The primary applications are atmospheric modeling, computational fluid dynamics, computational chemistry, and statistical modeling. Projects are allocated time on the HPC system through an annual review process.
In FY 2021, projects were allocated around 30 million CPU hours.
Sophisticated visualization hardware and software support high-end, R&D visualization computing, providing the ideal technology for projects such as modeling the human respiratory system or wind flow through an urban landscape. These visualizations can be converted to animations for display or graphics suitable for publishing.
