SUMMARY:MS2F - Exascale Plasma Simulations, Methods and Technologies for F
 usion, Plasma Accelerator and Space Physics Research (Part 2/2)
DESCRIPTION:Minisymposium\n\nPlasmas constitute paradigmatic examples of c
 omplex physical systems, involving nonlinear, multiscale processes far fro
 m thermodynamic equilibrium. HPC and virtual prototyping play an increasin
 gly crucial role in explaining and predicting observations as well as in d
 esigning more effective plasma systems and manufacturing processes. This p
 rovides novel pathways to reducing the risks, costs, and time often associ
 ated with the design and construction of new devices and large experimenta
 l facilities. The present mini-symposium brings together scientists, resea
 rchers, and practitioners from plasma physics, applied mathematics, and co
 mputer science (incl. HPC, computational science, software engineering, an
 d data analytics) to discuss computational tools and methodologies needed 
 to tackle critical grand challenges in plasma physics: optimising magnetic
  confinement fusion devices, developing new accelerator technologies, and 
 predicting space weather. Meanwhile, the tools and techniques devised in t
 hese contexts are applicable to a much wider range of problems involving n
 atural and laboratory plasmas and fluids.\n\nParallel-In-Time Integration 
 with Particle-In-Fourier Schemes\n\nParticle-In-Fourier (PIF) schemes are 
 attractive for long-time integration kinetic plasma simulations as they co
 nserve charge, momentum and energy, exhibit a variational structure, do no
 t have aliasing and have excellent stability properties. However, they are
  typically more expensive than the commo...\n\n\nSriramkrishnan Muralikris

 nleashing the Power of Multiple GPUs for ECsim Using OpenACC\n\nThe Partic
 le-In-Cell (PIC) method is a particle-mesh technique widely used to model 
 the kinetic nature of plasmas. Macroparticles representative of several pl
 asma particles interact via electromagnetic fields that they produce. Thes
 e fields are calculated by solving Maxwell's equations on a fixed gr...\n\

 (NVIDIA Inc.)\n---------------------\nWhole-Device Simulations of Fusion P
 lasmas with GENE\n\nIn order to achieve a burning (i.e., self-heating) pla
 sma which is suitable for electricity production in a fusion power plant, 
 the so-called energy confinement time needs to exceed a threshold given by
  the Lawson criterion. The physical process which sets this key figure of 
 merit is turbulent trans...\n\n\nFrank Jenko (Max Planck Institute for Pla
 sma Physics) and Tilman Dannert (Max Planck Computing and Data Facility)\n
 ---------------------\nThe Beam, Plasma & Accelerator Simulation Toolkit (
 BLAST) at Exascale\n\nParticle accelerators, among the largest, most compl
 ex devices, demand increasingly sophisticated computational tools for the 
 design and optimization of the next generation of accelerators that will m
 eet the challenges of increasing energy, intensity, accuracy, compactness,
  complexity and efficiency...\n\n\nAxel Huebl, Remi Lehe, Edoardo Zoni, Ol
