2-2-2-2-2-2-2-2-2-2-2-2-2 From: afolch <arnau.folch@xxxxxx> Dear colleague, We hope this email finds you well. Time is approaching for virtual EGU21 abstract submission (deadline 13 January 2021 at 13:00 CET) and we would like to draw your attention to the following shared Session: *Towards Exascale Supercomputing in Solid Earth Geoscience and Geohazards* Programme groups: NH6.9/EMRP2.3/ESSI2.4/GD8.4/GMPV1.6/SM8.3 Convener: Arnau Folch Co-conveners: Steven J. Gibbons, Marisol Monterrubio-Velasco, Jean-Pierre Vilotte, Sara Aniko Wirp Link: https://meetingorganizer.copernicus.org/EGU21/sessionmodification/39619 Session Details: The leading-edge computational and data facilities of the forthcoming Exascale era will bring a variety of currently inaccessible Solid Earth computational challenges within reach. Firstly, many Geoscience calculations that are currently unaffordable due to the size of the computational domain, necessary model resolution, or insurmountable data requirements, will become increasingly tractable. Secondly, Exascale supercomputing will facilitate probabilistic framework approaches to ever larger and more complex problems, through larger ensembles of model realizations and incorporating high-end data inversion, model data assimilation, and uncertainty quantification. Finally, Urgent High Performance Computing will become a reality with complex numerical simulations, potentially with large model ensembles, becoming possible in near real-time. Numerous natural hazards which pose a direct threat to human life and critical infrastructure (e.g. earthquakes, volcanic eruptions, wildfire, landslides, and tsunamis) can require rapid and well-informed decision making in the emergency management process. The basis for these decisions is often provided by complex and data-intensive numerical models and we face a challenge of designing and implementing robust and powerful workflows (including computing, data management, sharing and logistics, and post processing) which present stakeholders with relevant and accurate results in a timely manner. This transdisciplinary session seeks contributions related to the preparation of codes for Exascale, geoscience workflows and services, adapting codes for emerging hybrid hardware architectures, e-services demanding Urgent HPC, early warning and forecasts for geohazards, hazard assessment, and high-performance data analytics. Examples include codes and workflows for near real-time seismic simulations, full-waveform seismic inversion, ensemble-based forecasts, faster than real-time tsunami simulation, magneto-hydrodynamics simulations, and physics-based hazard assessment. This session is organised by the Center of Excellence for Exascale in Solid Earth (ChEESE) with the support of the European Plate Observatory System (EPOS), the EUDAT Collaborative Data Infrastructure (EUDAT CDI) and the Partnership for Advanced Computing in Europe (PRACE). The organisers plan to submit a proposal for an Advances in Geosciences (ADGEO) EGU General Assembly special volume on one or more EGU Divisions. Kind regards a happy new year. 2-2-2-2-2-2-2-2-2-2-2-2-2 ------------------------------
