Occigen supercomputer at GENCI used for seismology

Barbara Romanowicz from the Institut de Physique du Globe de Paris (IPGP) and the University of California, Berkeley studies the Earth's mantle. Her objective: A better understanding of the internal structure and dynamics of Earth's mantle, the movements of which explain plate tectonics and continental drift.
Thanks to their model, Barbara Romanowicz and her team have confirmed that "hotspots" volcanism is due to columns of hot material rising from the depths of the mantle, at the boundary with Earth's core and is not directly related to the diverging or converging motions of tectonic plates. Scientists have also been able to link these columns of hot material to twenty-some hot volcanoes around the world. These calculations have used 400,000 core hours on the GENCI supercomputer Occigen in Montpellier France. Also supercomputing capacity at the National Energy Research Scientific Center (NERSC) were used.
