Alice-Agnes Gabriel, a ChEESE partner from the Department of Earth and Environmental Sciences Geophysics at Ludwig-Maximilians-University of Munich (LMU), won the 2020 PRACE Ada Lovelace Award for HPC for her contributions to and impact on HPC in Europe.

The Center of Excellence for Exascale in Solid Earth (ChEESE) has doubled the speedup of seismic wave propagation code SPECFEM3D through the software optimization efforts of project partner Bull/Atos.
Mauricio Hanzich and Claudia Rosas presented a webinar that focused on the work of ChEESE in integrating HPC and data across Solid Earth related disciplines in Europe and how POP conducts performance assessments on all the codes that ChEESE uses.
Mitiga Solutions is a Barcelona Supercomputing Center spinoff that uses ChEESE pilot demonstrators and codes to predict and mitigate the impact of natural hazards to air traffic management.
ChEESE researchers recently participated in the CINECA GPU Hackathon which took place in CINECA Rome.
Through the optimization work of BULL/ATOS, SPECFEM3D can now take advantage of modern x86 SIMD (Single Instruction Multiple data) instructions sets such as AVX2 or AVX512. These optimizations allow higher processing rates by allowing each core to handle multiple computations simultaneously. This has already allowed the code to obtain a speedup of 2x on one of CHEESE test cases on ATOS’ BullSequana machine equipped with Intel processor Skylake 6148, thus enabling a faster execution of the Pilot Demonstrators.
ChEESE partners recently came together at INGV in Rome, Italy for a Project Supervisory Board (PSB) meeting on September 18, 2019 followed by an inter-work package technical face-to-face meeting to discuss technical work package updates on September 19-20, 2019.
How to build a society resilient to natural catastrophes: ChEESE team defines HPC service prototypes
In cases of a natural catastrophes, efficient computational algorithms and the most powerful computer in Europe might be required to help manage these emergencies, in the shortest possible time.
Tsunamis are long water waves caused by other large natural hazards such as earthquakes, landslides, and volcanoes. They present a threat to near-coastal populations and infrastructure. In ChEESE, new ways of quantifying tsunami hazard will be developed. The main aim is to utilize large High Performance Computing resources to map the tsunami inundation hazard at very high resolution while, at the same time, estimating the large uncertainty associated with tsunamis.
ChEESE partners from the Barcelona Performance Computing Center (BSC) are in charge of Task 3.2, which proposes to explore parallel mesh partitioning strategies to enable dynamic load balance of the different simulation codes.
ChEESE researchers came out in full force at the 27th International Union of Geodesy and Geophysics (IUGG) General Assembly, held in Montreal, Canada on July 8-18, 2019.
The IUGG General Assembly is one of the biggest international events for those in the fields of Earth sciences and geosciences. It is held every four years, during which there are over 4,000 attendees.
