MS4
Extreme-Scale Computational Astrophysics

9:30 AM - 11:30 AM
Room: Picasso

To understand our universe and our place in it will require that we understand the universe on all scales, from the evolution of the universe as a whole, to the formation of its large-scale structure, galaxies, stars planets, and compact objects such as neutron stars and black holes. Understanding the universe on each scale presents extreme-scale (peta- to exa-scale) computing challenges, and the challenge of connecting phenomena on all scales to provide a seamless description of the universe and its evolution will take us beyond even the exascale. In this minisymposium, some of these challenges will be addressed. The speakers will present the science, its importance and connections to other initiatives and fields, the current state of the art in their respective fields, and the path forward over the next decade, as supercomputing architectures, astrophysical models, and massively parallel computing advance.
