WholeSun: New codes and frameworks for exascale computing for multi-scale simulations

We live around an active magnetic star, our Sun, that has a direct impact on our technological society through its variability and eruptive behaviour.

Simulation of the solar dynamo that generates the magnetic field (left, simulation by the group in Paris) and a simulation of the outer solar atmosphere (right, simulation by RoCS) where the emerging field interacts with pre-existing field creating explosions and jets.

Despite decades of intense research, fundamental questions such as: How does the Sun work? Why does it possess a magnetic cycle, dark spots and a dynamic hot atmosphere? remain mostly unanswered.

This project is closely connected to the ERC Synergy Grant Whole Sun project, where we aim at tackling these key questions as a coherent whole for the first time. The advent of Exa-scale computers makes such a challenge within our reach but new methods and codes need to be developed.

This project involves the further development of the framework DISPATCH, that enables scaling to millions of cores, and the implementation of radiation magnetohydrodynamics solvers on emerging Exa-scale hardware.

The project is hosted by the Rosseland Centre for Solar Physics (RoCS).
