Learning more about the sun
The HPC project “Solar Atmospheric Modelling” uses the applications Bifrost and Dispatch to simulate the Sun’s atmosphere, the outer layers from which sunlight comes. The simulations are compared with observations from solar telescopes on the ground and space, to learn more about how the Sun, and thus other stars, works.
The applications are highly parallel, which mean that they use numerous processor cores to perform calculations faster. On Betzy, Bifrost has been tested on more than 131,000 cores, and application developers are collaborating to adapt the code to the GPU. This makes the applications particularly suitable for piloting the new supercomputer LUMI.
