EuroHPC SPACE CoE: Redesigning Scalable Parallel Astrophysical Codes for Exascale. Invited Paper

Le résumé fourni par la source

High Performance Computing (HPC) based simulations are crucial in Astrophysics & Cosmology (A&C), helping scientists investigate and understand complex astrophysical phenomena.Taking advantage of exascale computing capabilities is essential for these efforts.However, the unprecedented architectural complexity of exascale systems impacts legacy codes.The SPACE Centre of Excellence (CoE) aims to re-engineer key astrophysical codes to tackle new computational challenges by adopting innovative programming paradigms and software (SW) solutions.SPACE brings together scientists, code developers, HPC experts, hardware (HW) manufacturers, and SW developers.This collaboration enhances exascale A&C applications, promoting the use of exascale and postexascale computing capabilities.Additionally, SPACE addresses high-performance data analysis for the massive data outputs from exascale simulations and modern observations, using machine learning (ML) and visualisation tools.The project facilitates application deployment across platforms by focusing on code repositories and data sharing, integrating European astrophysical communities around exascale computing with standardised SW and data protocols.
