High-Performance Computing (HPC)

In Earth System Science (ESS), High-Performance Computing (HPC) refers to the use of powerful computing systems to perform large-scale, complex calculations and simulations required to understand and predict Earth’s systems. These systems include the atmosphere, oceans, land surfaces, and biosphere, all of which interact in complex ways. ESS relies on HPC to process and analyze vast amounts of data generated by models and observations, enabling scientists to study and predict phenomena ranging from climate change to weather patterns. For the NFDI4Earth, the Interest Group High-Performance Computing in Earth System Sciences (IG HPC in ESS) provides a forum for HPC centers and users, working towards a simplified re-use and FAIR handling of Earth System Science data on large computing systems.

Several articles have been published in the Living Handbook that deal with this topic in greater detail: * How to apply for a HPC project provides an insight into the possibilities of applying for HPC rescources at the 'Center for Information Services and High-Performance Computing (ZIH)' at the Technical University of Dresden * Interest Group High-Performance Computing in Earth System Sciences (IG HPC in ESS) provides information about the interest group's motivation and goals as well as, contact details * Overview on NFDI4Earth operated High Performance Computing service instances provides an overview of HPC service instances available within the NFDI4Earth * HPC and Cloud Computing - What is it and when should we use it describes an opinion on when and how traditional HPC services should be used in comparision to cloud-based services.
