EuroHPC Summit Week (EHPCSW) is an annual event gathers the main technology suppliers and HPC infrastructures to scientific and industrial HPC users in Europe. This year´s edition took place on 22-26 March 2021.
Our knowledge of the deep structures of the earth is largely due to geophysical methods. Indeed, it is impossible to directly observe the composition or structures at depths of several tens, hundreds or thousands of kilometers. We therefore have to probe the earth indirectly from measurements made by instruments on the earth's surface. Among geophysical methods, seismic tomography uses measurements of seismic waves that have propagated through the earth to calculate the properties of geological environments at depth.
