Description du projet
Une nouvelle ère dans les simulations haute performance de plasma
Les réactions de fusion combinent des éléments légers sous forme de plasma, un gaz chaud et chargé composé d’ions positifs et d’électrons en mouvement, avec des propriétés uniques distinctes de celles des solides, des liquides ou des gaz. La modélisation des plasmas est à l’avant-garde du calcul à haute performance. L’UE a énormément investi dans la préparation des codes de simulation des plasmas en vue de l’ère exascale. Le projet Plasma-PEPSC, financé par l’UE, entend maximiser les performances parallèles et l’efficacité de quatre codes plasma européens phares ayant une large base d’utilisateurs: BIT, GENE, PIConGPU et Vlasiator. Les simulations avancées sur les plateformes pré-exascale actuelles et exascale à venir devraient permettre de contrôler les interfaces plasma-matériau, d’optimiser les plasmas de fusion à confinement magnétique, de concevoir les accélérateurs de plasma de nouvelle génération et de prédire la dynamique des plasmas spatiaux dans la magnétosphère de la Terre.
Objectif
Plasma science has been at the forefront of HPC for several decades, driving and at the same time benefiting greatly from innovative hardware and software developments. The overall goal of Plasma-PEPSC is to take this development to the next level, enabling scientific breakthroughs in plasma science Grand Challenges through exascale computing and extreme-scale data analytics. Specifically, we aim to enable unprecedented simulations on current pre-exascale and future exascale platforms in Europe to control plasma-material interfaces, optimize magnetically confined fusion plasmas, design next-generation plasma accelerators and predict space plasma dynamics in the Earth’s magnetosphere. We achieve these goals by maximizing the parallel performance and efficiency of four European flagship plasma codes with a large user base: BIT, GENE, PIConGPU, and Vlasiator. Here, we will build on algorithmic advances (regarding load balancing, resilience, and data compression) as well as on programming model and library developments (MPI, accelerator and data movement APIs and runtimes, in-situ data analysis). We ensure an integrated HPC software engineering approach for deploying, verifying, and validating extreme-scale kinetic plasma simulations that can serve as a community standard. We will establish a continuous and integrated co-design methodology to provide/receive direct input to/from the design and development of the EPI Processor and accelerator, will exploit synergies through collaborations with other CoEs, EuroHPC, and Competence Centers for cross-fertilization, adoption and full exploitation of the Plasma-PEPSC codes. Plasma-PEPSC brings together an exceptional, interdisciplinary group of highly-recognized leading scientists from academia, research centres, and HPC centres, with decades of experience in algorithmic and method developments, extreme-scale plasma simulations, and application optimizations with high involvement in strategic EuroHPC projects and initiatives.
