Frontiers in Planetary and Stellar Magnetism through High-Performance Computing

Показать описание

A state-of-the-art simulation of magnetic field generation in Earth's liquid iron core. The simulation grid consists of more than 2 billion points. The movie shows the velocity (left) and the magnetic field (right) in a rotating frame of reference and close to the core-mantle boundary. The red/blue and orange/blue show positive and negative values. Computing support for this simulation was provided by ALCF/INCITE grant "Frontiers in Planetary and Stellar Magnetism through High-Performance Computing" project (PI: Jonathan Aurnou, UCLA).

The project was awarded computing time and resources at the ALCF through the Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program supported by DOE’s Office of Science. The development of the Rayleigh code was funded by the Computational Infrastructure for Geodynamics, which is supported by the National Science Foundation.

This research used resources of the Argonne Leadership Computing Facility at Argonne National Laboratory, which is Department of Energy Office of Science User Facility supported under DE-AC02-06CH11357.
