Descrizione del progetto
Una nuova era nelle simulazioni al plasma ad alte prestazioni
Le reazioni di fusione combinano elementi leggeri sotto forma di plasma, ovvero un incandescente gas carico elettricamente costituito da ioni positivi ed elettroni liberi di muoversi, caratterizzato da proprietà uniche differenti rispetto a quelle che contraddistinguono i solidi, i liquidi o i gas. La modellizzazione del plasma si trova in prima linea nell’ambito del calcolo ad alte prestazioni. L’UE ha investito fortemente nella preparazione di codici per le simulazioni al plasma, destinati all’era dell’esascala. Il progetto Plasma-PEPSC, finanziato dall’UE, si prefigge di potenziare al massimo le prestazioni parallele e l’efficienza di quattro codici di riferimento per il plasma che vantano un’ampia base di utenti: BIT, GENE, PIConGPU e Vlasiator. Le simulazioni avanzate sulle attuali piattaforme pre-esascala e su quelle future su esascala dovrebbero consentire di controllare le interfacce tra plasma e materiali, di ottimizzare i plasmi da fusione a confinamento magnetico, di progettare gli acceleratori al plasma di prossima generazione e di prevedere le dinamiche del plasma spaziale nella magnetosfera terrestre.
Obiettivo
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.
