SUMMARY:MS3C - Mathematical Developments for Magnetic Fusion HPC Applicati
 ons
DESCRIPTION:The quest for fusion as an environmentally benign, virtually i
 nexhaustible energy source has recently taken frontstage thanks to a numbe
 r of breakthroughs such as a new world record for fusion power or the firs
 t demonstration of energetic breakeven. This minisymposium is dedicated to
  the development and application of new mathematical methods and framework
 s to improve the HPC simulation of magnetic fusion plasmas, the talks will
  cover communications-avoiding DG schemes for the Vlasov equation, using h
 ierarchical matrices for accelerating the simulation of neutral particles,
  variable precision computing for multi-model applications and the GPU acc
 eleration of a Python based framework for HPC simulation of plasmas.\n\nAc
 celerated Neutral Solvers for Plasma Simulations\n\nThe simulation of turb
 ulence in the boundary region of a tokamak is crucial for understanding an
 d optimizing the performance of fusion reactors. However, these simulation
 s pose significant computational challenges due to the complex plasma dyna
 mics at the boundary. In this talk, we explore how low-r...\n\n\nMargherit

 C)\n---------------------\nRecent Developments in the Modern Particle Solv
 er GEMPICX\n\nThe GEMPICX code is a geometric particle in cell solver for 
 plasma physics models. It can handle both electrostatic and fully magnetic
  simulations. The code is able to leverage modern (including GPU-based) hi
 gh performance computing systems by utilizing the AMREX framework for bloc
 k structured adapt...\n\n\nMartina Prugger (Max Planck Institute for Plasm
 a Physics)\n---------------------\nCommunication-Avoiding Lagrangian-Euler
 ian Discretization for the Vlasov Equation\n\nThis talk will discuss two e
 fficiency-enhancements of the discontinuous Galerkin solution of the Vlaso
 v equation: communication-avoiding boundary exchange as well as an arbitra
 ry Lagrangian-Eulerian implementation of the gyration about the magnetic f
 ield lines. The communication of boundary data in ...\n\n\nKatharina Korma

  Plasma Simulations\n\nStruphy (STRUcture-Preserving HYbrid codes) is an o
 pen-source Python package for solving plasma physics PDEs based on finite 
 element exterior calculus (FEEC), particle-in-cell (PIC) and purely Lagran
 gian methods (smoothed-particle hydrodynamics, SPH). Its purpose is to pro
 vide a unified development ...\n\n\nStefan Possanner and Max Lindqvist (Ma
