[ONLINE] SPACE: Presentation of the ChaNGa code and the Charm++ framework

Annotation

The target audience will be researchers interested in HPC and the challenges that astrophysics codes present when scaling towards exa-scale. We will discuss both the benefits and difficulties of the ChaNGa code and the Charm++ framework. We will also discuss recent and future improvements to the code.

Language

English

Level

Intermediate, advanced; the talk is intended for experts in HPC who do not necessarily have domain-specific knowledge in cosmology and astrophysics.

Prerequisites

Experience in HPC.

Tutors

Robert Wissing is a postdoc working at the University of Oslo, with publications in the field of numerical methods, magnetohydrodynamics (MHD), dynamo processes, galaxy formation, equation of state and planetary impacts. He has developed the MHD module for the ChaNGa and Gasoline codes and is currently involved in improving the scalability of the ChaNGa code.
