MOLIMEXA – Pokročilé modelovanie interakcií svetlo-hmota na exascale superpočítačoch blízkej budúcnosti
Advanced Modelling of Light-Matter Interactions on Near-Term ExaScale Supercomputers
Program: Plán obnovy EÚ
Project leader: Mgr. Komorovský Stanislav, PhD.
Annotation: Interaction of the matter with light is one of the most important means for unravelling its structure and properties. Recent advances in laser technology have opened the way towards attosecond laser experiments, awarded by Nobel Prize in 2023. Theoretical description of these processes is exceptionally complex due to the electron-nuclear dynamics. Simulations in solids require the solution of Schrödinger or Dirac equation in real time, which is a formidable task for CPU-based computers due to a large number of atoms inside a model cell and a large number of time steps required for high resolution. The main objective of this project is to develop innovative algorithms and parallel computational procedures for the simulation of attosecond experiments that leverage the power of exascale computer systems. This will be achieved by data and task decomposition and distribution across multi-processing units such as CPUs and GPUs, while ensuring equal workload for each processing unit.
