Center of Excellence in Solid Earth - Second Phase (ChEESE)


The scientific ambition of the second phase of the EU project Center of Excellence in Solid Earth (ChEESE-2P) is to prepare 11 community flagship codes to address 12 domain-specific Exascale Computational Challenges (ECC), enlarging the areas covered during the first implementation phase (computational seismology, magnetohydrodynamics, physical volcanology, and tsunamis) with two additional disciplines (geodynamics and modelling of glacier hazards). 

Codes will be optimised in terms of performance on different accelerators, scalability, deployment, containerisation, and portability across current pre-exascale systems and hardware architectures emerging from the EuroHPC Pilots by co-designing with mini-apps. 

Optimisation will also include heterogeneous single-node and multi-node performance and continuous efficiency monitoring using the Performance Optimisation and Productivity (POP) metrics. Emphasis will be given on the uptake by science, public administration and industry, including training and capacity building in cooperation with National Competence Centers (NCCs). 

Codes and workflows will combine to farm a new generation of 9 Pilot Demonstrators (PDs) underpinned by concepts like multi-scale, multi-source, and multi-physics. The PDs will materialise in 15 Simulation Cases (SCs) representing capability and capacity use cases of particular relevance in terms of science, social relevance, or urgency (the capability SCs include 4 potential Scientific Grand Challenges, i.e. cases that can require an extreme-scale access mode). 

The SCs will produce relevant EOSC-enabled datasets and enable services on aspects of geohazards like urgent computing, early warning forecast, hazard assessment, or fostering an emergency access mode in EuroHPC tier-0/tier-1 systems for geohazardous events (earthquakes, tsunamis and volcanoes), including access policy recommendations. Finally, ChEESE-2P will liaise, align, and synergize with other domain-specific European projects and longer-term mission-like initiatives like Destination Earth.
