The ChEESE CoE is a new initiative to integrate HPC and data across Solid Earth related disciplines in Europe. One of its main goals is to prepare ten flagship codes for exascale environments. These codes cover fields of study highly relevant for urgent computing, probabilistic hazard assessment and data science, such as computational seismology, magnetohydrodynamics, physical volcanology, and tsunami modeling.

POP conducted performance assessments of all these codes at the start of the project and will do so again at the end. In this webinar, we looked in more detail at one of these, a physical volcanology code called Fall3D and explained how work conducted within ChEESE, aided by insights provided by the POP assessment, has led to a 10x improvement in scalability in a fairly short period of time.

The presentation slides are also available here.
