Plasma Exascale-Performance Simulations CoE - Pushing flagship plasma simulations codes to tackle exascale-enabled Grand Challenges via performance optimisation and codesign - Plasma-PEPSC Project ID: MC2302 Provider: Ministry of Education, Youth and Sports of the Czech Republic Period: Jan 01, 2023 - Dec 31, 2026 Principal Investigator: Priv. Doz. Dr. David Tskhakaya Co-investigators J. Hromádka, A. Podolník, P. Mácha Aims of the project: 1. Maximise the performance of four European plasma codes (BIT, GENE, PIConGPU, Vlasiator) in terms of parallel performance and efficiency on European exascale and pre-exascale systems. 2. Establish and ensure an integrated HPC software engineering approach for deploying, verifying, and validating extreme-scale kinetic plasma simulations that can serve as a community standard. 3. Establish a continuous and integrated co-design methodology for the four plasma codes to provide/ receive direct input to/ from the design and development of the EPI Processor from SiPearl, the European accelerator, EUPEX and EuPILOT. 4. Enable high-throughput analysis of the large simulation result datasets from the four high fidelity kinetic plasma simulations with optimised and scalable parallel I/O, data compression techniques for kinetic codes, online data analysis building on efficient data streaming, and integrated AI-based data analysis. 5. Exploit and maximise the usage of the computational power of accelerators available on current and next-generation European supercomputers for the four above-mentioned plasma simulation codes. 6. Create synergistic collaborations with other CoEs, EuroHPC, and Competence Centers for cross-fertilization and supporting the significant adoption and full exploitation of the Plasma-PEPSC simulation codes, methodology, approaches and ensuring synergies in preparing training hackathons, workshops, and conferences.
