Achieving high performance is a complicated task. Different levels have to be exploited - from single core performance up to cluster-wide performance. Furthermore, different techniques and skills have to be used.

Held virtually on October 26-29, 2020 the PRACE course "Tools & Techniques to quickly improve performances of HPC applications in Solid Earth" was developed in the CHEESE framework by CINECA staff to mostly focus on the main HPC issues for Earth Science.

ChEESE partner Alexey Cheptsov (HLRS) presented a tutorial titled "Development of Parallel Geoscientific Applications on High Performance Computing Architectures" at the Twelfth International Conference on Advanced Geographic Information Systems, Applications, and Services
(GEOProcessing 2020) on 22 November 2020.

The Center of Excellence in Performance Optimisation and Productivity (POP) has recently worked with ChEESE in order to improve the FALL3D code and the workflow developed in the project´s Pilot Demonstrator 6 - Probabilistic Volcanic Hazard Assessment (PVHA), that analyses several thousands of FALL3D simulations. The resulting Probabilistic Volcanic Hazard Assessment Work Flow package (PVHA_WF) has allowed FALL3D to achieve 588x and 488x execution time speedups. 

ChEESE proudly announces that two female researchers will present their work in the lightning talk session of the Women in HPC Workshop at SC20 on 11 November 2020. Get to know them! In these interviews Marisol Monterrubio-Velasco and Beatriz Martinez Montesinos introduce themselves and their work and share what being a woman in HPC means for them.

ChEESE partners from LMU Munich, the Technical University of Munich (TUM), ETH Zurich, the French National Centre for Scientific Research (CNRS), High Performance Computing Center, Stuttgart (HLRS) and the Barcelona Supercomputing Center (

One of the partners in the ChEESE consortium is Istituto Nazionale di Geofisica e Vulcanologia (INGV), the largest Italian public research body operating in the field of geophysics whose activities span from fundamental to applied research. The institute plays a role of direct societal relevance by being in charge of both hazard assessment and 24/7 real-time monitoring, early warning and forecasting for various geophysical phenomena. 

ChEESE has been awarded over 90 million core hours to be used towards HPC-related research in tsunamis and earthquakes after winning two separate project access grants.

ChEESE coordinator Arnau Folch was invited to give a presentation due to his close working relationship with Italian institutions such as Istituto Nazionale di Geofisica e Vulcanologia  and CINECA. His talk, which took place under the Geophysics and physics of the environment session on 18 September 2020 at 15:00, was titled “A computational model for atmospheric transport and deposition of tephra,dust, SO2and radionuclides”. 

Are you fascinated by high-performance computing and seismology? Are you curious to know how to numerically solve complex wave propagation problems?

ChEESE tackles the problem of having to work with a large amount of data in one of its work packages, together with the workflow management activity, with the concrete goal of extending and consolidating the use of EUDAT CDI data services among the partners. The choice to use EUDAT CDI data services for Solid Earth was pioneered by EPOS with a pilot project, but with the intention of extending the effort to other EPOS domains and services.

Within the ChEESE Center of Excellence for Exascale in Solid Earth (ChEESE),  the earthquake simulation software SeisSol, one of the 10 ChEESE flagship codes, is being ported to GPU-based supercomputers. First simulations have now been  executed on Marconi100 and Piz Daint, two of the largest European supercomputers.
